Keyworder updates: Groups

Feature updates to keyword plugin: Grouping!

https://github.com/taoist22/sn-keyworder/releases

Features

• Multi-keyword insertion — check any number of keywords and insert them all in one tap; each keyword lands as a separate, movable element in wrapped rows near the bottom of the page
• Selection to add keyword — lasso handwritten or typed text in notes, or select text in PDFs/EPUBs, then tap the Keyworder button and save it directly to your keyword list; works with OCR for handwriting
• Native index integration — automatically adds each keyword to the device's built-in keyword index for page navigation
• In-plugin keyword management — add, delete, and pin keywords directly from the plugin; changes persist automatically
• Group-based keyword sets — create reusable groups such as meetings, classes, projects, or assignments, then assign existing keywords to one or more groups
• Bulk import — use the Keyword Builder web tool to create a keywords.json file, then load the list onto the device
• Pinned keywords — keep your most-used keywords at the top of the list for zero-scroll access
• Structured keywords — optionally save a keyword with a short key so it inserts as key:value for tools such as sn-query; key capitalization is preserved for display and insertion
• Keyword views — filter the picker by pinned keywords or by group, then select the filtered view when you want a batch
• Responsive Nomad and Manta layout — larger, denser panels with compact two-column keyword lists on supported screen sizes
• A-Z letter rail — filter the Keyword, Manage Keywords, and Manage Groups screens by first letter using the vertical rail on the right side of the list

FrameClip Plugin

FrameClip for Supernote

FrameClip captures a region of a PDF page as a PNG and inserts it into a note. It renders the page natively, lets you draw and fine-tune a crop, optionally darkens it for faint scans, and keeps a gallery of clips you can drop into any note.

>

What it does

• Render-then-crop: opens the current PDF page, renders it to an image, and lets you crop from that — no screenshots required.
• Draw-first cropping: drag anywhere on the page to draw the crop box, drag the corner to resize, and use the on-screen buttons to nudge/resize precisely.
• Page navigation: ‹ Prev / Next › step through a multi-page PDF without leaving the plugin, so you can grab several regions in one session.
• Tone adjustment (great for light scans): a row of boxes — 
  • Auto · Off · 1 · 2 · 3 · 4 · B/W.
  • Contrast is pivoted at white, so the background stays clean while faint text darkens. Auto picks a gentle level for you; B/Wproduces crisp 1-bit black/white (best for plain text).
• Multi-clip gallery: every capture is saved. In a note, FrameClip shows a thumbnail grid — pick one and insert it, or delete clips you no longer need.

Workflow

1. Open a PDF and launch FrameClip from the plugin toolbar.
2. Draw a box around the region you want; fine-tune with the buttons or corner handle.
3. (Optional) Use Prev/Next to capture from other pages.
4. Tap Capture Clip. On the saved screen, adjust the Tone if needed.
5. Tap Capture Another to grab more, or Done to exit.
6. Open the destination note and launch FrameClip there.
7. Pick a clip from the gallery and tap Insert Selected. Resize it in the note as usual.

Saved clips live in /storage/emulated/0/MyStyle/FrameClip/.

Install

Side-load the plugin package onto your device:

1. Download FrameClip.snplg from the latest release.
2. Copy it to your Supernote and install it via the plugin manager.

Build from source

Requires Node 18+ and a working React Native / Android toolchain.

npm install
# Always clear stale generated output first, or changes may appear not to apply:
rm -rf build/generated build/outputs
./buildPlugin.sh

The packaged plugin is written to build/outputs/FrameClip.snplg.

Project layout

• App.tsx — React UI and crop/tone/gallery logic.
• android/app/src/main/java/com/snframeclip/FrameClipNativeModule.java — native page render, crop, contrast/threshold, and clip management.
• PluginConfig.json — Supernote plugin manifest.

SN Query Advanced Query Tab

SNQuery is a powerful plugin for Supernote that brings Obsidian Dataview-like querying capabilities to your device, enabling dashboard creation and note management without needing to export your notes to a PC.

Current Release: https://github.com/taoist22/sn-query/releases/tag/v0.2.1

Important

SNQuery searches the same folder as the note where you run the plugin. It does not scan the entire device.

For reliability and performance, [SNQ] property blocks and loose inline properties must be on page 1 of each note to be found during folder scans. Native Supernote keywords can still be used across matching notes, but full-note property scanning is intentionally not performed.

Features

• Dataview-like Syntax: Query your notes using familiar TABLE and LIST commands tailored for Supernote's offline environment.
• On-Demand Dashboards: Create dashboards that track keywords and property fields. (Note: Dashboards do not auto-update; you simply tap "Run" on your saved queries to fetch the latest data).
• Templates & Config: Create, edit, and insert reusable [SNQ] item templates.
• Selected Block Editing: Lasso an existing [SNQ] block and open SNQuery from the lasso menu to edit that block directly.
• Saved Queries: Save your frequently used queries and run them with a single tap.
• Progress Feedback: Folder scans show live progress so long-running queries are easier to trust.
• Column Statistics: Calculate averages, sums, minimums, maximums, and counts for numeric fields.

Launching SNQuery

SNQuery has two launch paths:

• Main toolbar/plugin icon opens the normal Dashboard workflow.
• Lasso menu on a selected [SNQ] block opens the dedicated editor for that selected block.

Use the main toolbar when you want to run dashboards, saved queries, or insert new templates. Use the lasso menu when you want to update an existing [SNQ] block already placed on a note page.

Scan Scope

SNQuery is designed to keep scans predictable on-device:

• It scans .note files in the current folder only.
• [SNQ]...[/SNQ] data blocks must be placed on page 1 of each note.
• Loose properties outside an [SNQ] block must also be on page 1.
• Keyword-only searches are faster because they use Supernote's native keyword metadata instead of reading note elements.
• SNQuery does not OCR handwriting; handwritten content must be converted to text or tagged with native keywords to be queried.
• Inserted dashboards are snapshots; run the query again to refresh the results.

Keywords vs Properties

Native Supernote keywords are best used for broad, human-meaningful categories like #journal, #todo, #sleep, #meeting, or #project-alpha. They are fast to search and are not dependent on [SNQ] blocks.

Use [SNQ] properties for structured values you want to filter, sort, or calculate, such as status: open, due: 2026-06-25, sleep_score: 81, or sleep_time: 7:25. Avoid stuffing property-style data into native keywords; too many overly specific keywords can make Supernote's keyword system harder to browse and less useful.

Common Workflows

Todo Dashboard

Add one [SNQ] block for each task you want to track:

[SNQ]
type: todo
task: Call Nancy
status: open
due: 2026-06-26
[/SNQ]

Then query it:

TABLE task AS "Task", due AS "Due", status AS "Status"
WHERE type = todo AND status = open
SORT due ASC

Sleep Tracking

Time durations can be entered as hours and minutes, such as 7:25 or 6h55m. SNQuery treats those as durations for statistics.

[SNQ]
type: sleep
date: 2026-06-19
sleep_score: 81
sleep_time: 7:25
[/SNQ]


TABLE date AS "Date", sleep_score AS "Sleep Score", sleep_time AS "Sleep Time"
WHERE type = sleep
STATS AVG(sleep_score), AVG(sleep_time), MIN(sleep_score), MAX(sleep_score)
SORT date DESC

Meeting Or Event Dashboard

[SNQ]
type: meeting
meeting: Finance
date: 2026-06-25
time: 11:00
summary: Budget review
[/SNQ]


TABLE meeting AS "Meeting", date AS "Date", time AS "Time", summary AS "Summary"
WHERE type = meeting
SORT date ASC

Current Limitations

• SNQuery scans the current folder only.
• Subfolders are not included yet.
• [SNQ] blocks and loose inline properties must be on page 1 for folder scans.
• SNQuery does not connect to Supernote's native Tasks or Calendar apps.
• Inserted dashboards are static snapshots and must be rerun to refresh.

Installation

1. Build or download the SNQuery.snplg file.
2. Transfer the .snplg file to your Supernote device via USB or Supernote Cloud.
3. Open the plugin manager on your Supernote and load the plugin.

Documentation

For comprehensive instructions on query syntax, setting up dashboards, and using templates, please refer to the User Manual.

Unfortunately, during an upgrade to the plugin today, I found a memory leak in one of the critical APIs (getElements) that gave this plugin relevance. Since that severely limits the functionality of the plugin, I've decided to remove it until and if that issue is resolved.

Flashcard plugin

I've been working on this plugin for weeks and I think it is finally mostly stable. There are a couple of quirks I hope to iron out like having to tap twice on Insert Flashcard after entering text/edits etc. It is not a small plugin either at 8MB. Please test and let me know what you think!

Flashcards for Supernote

Latest Release

Flashcards is a beta spaced-repetition flashcard plugin for Supernote Nomad and Manta. It lets you create decks, add cards manually, turn lassoed handwriting into question/answer cards with OCR, study with FSRS scheduling, and move basic text cards between the plugin and Anki Desktop.

>

Features

• Create, select, and delete decks
• Add flashcards manually
• Add flashcards from handwritten notes with the lasso toolbar
• Review cards with a temporary editable guess box
• Schedule reviews with FSRS
• View basic deck stats
• Import basic Anki Desktop plain text exports
• Export decks back to Anki-compatible plain text

Installation

1. Download Flashcards.snplg from the latest GitHub release.
2. Copy Flashcards.snplg into the MyStyle folder on your Supernote.
3. On the Supernote, open Manage Plugins.
4. Add/install the plugin from MyStyle.
5. Open a note and tap the plugin icon to launch Flashcards.

Creating Decks

1. Open Flashcards from the plugin menu.
2. On the Decks screen, enter a deck name.
3. Tap Create Deck.
4. Tap a deck to open it.

Each deck shows total cards, due cards, reviews completed today, and total reviews.

Creating Flashcards

There are two ways to create cards.

Manual Cards

1. Open a deck.
2. Tap Add Manually.
3. Enter the question.
4. Enter the answer.
5. Choose the target deck.
6. Tap Add Flashcard.

Handwritten Cards With Lasso OCR

1. In a Supernote note, write the question on one line.
2. Write the answer on the line below it.
3. Lasso both handwritten lines together.
4. Tap Add Flashcard in the lasso toolbar.
5. The plugin OCRs the top line as the question and the lower line as the answer.
6. Edit the recognized text if needed.
7. Choose the target deck.
8. Tap Add Flashcard.

For best OCR results, keep the question and answer on separate horizontal lines with a little vertical space between them.

Studying Cards

1. Open a deck.
2. Tap Study Due or Study.
3. Read the question.
4. Use the editable Guess box to type or handwrite your answer.
5. Tap Show Answer.
6. Rate your recall:
   • Again
   • Hard
   • Good
   • Easy

The guess is temporary. It is cleared when you reveal the answer or move to the next card, and it is never saved.

Editing Cards

1. Open a deck.
2. Tap a card in the card list.
3. Edit the question, answer, or deck.
4. Tap Save Changes.

Deleting a card removes it from the plugin and also removes its local review history.

Anki Import

The plugin supports basic text cards from Anki Desktop. It does not import .apkg, .colpkg, media, tags, note types, cloze behavior, or Anki scheduling.

Export From Anki Desktop

In Anki Desktop:

1. Select the deck.
2. Choose Export.
3. Select Notes in Plain Text (.txt).
4. Recommended options:
   • Include deck name: enabled
   • Include unique identifier: enabled
   • Include HTML and media references: disabled
   • Include tags: disabled
   • Include note type name: disabled
5. Save the .txt file.

Put the File on Supernote

Copy the Anki .txt export into this folder on the Supernote:

EXPORT/sn-flashcards

If the folder does not exist yet, open Flashcards, tap Import Anki Text, and the plugin will create/show the folder path.

Import Into Flashcards

1. Open Flashcards.
2. Open any deck.
3. Tap Import Anki Text.
4. Confirm the displayed import folder.
5. Put the Anki .txt file there if it is not already present.
6. Tap Refresh.
7. Tap the file name.

The plugin reads Anki's #guid column and #deck column metadata. It creates the deck if needed, adds new cards, updates changed cards with matching GUIDs, and skips unchanged duplicates. Plugin FSRS scheduling stays independent from Anki.

Anki Export

1. Open the deck in Flashcards.
2. Tap Export Deck.
3. The plugin writes an Anki-compatible text file to Supernote's EXPORT folder.

The export uses Anki-style metadata:

#separator:tab
#html:false
#guid column:1
#deck column:2

When importing the exported file into Anki Desktop, map the two card fields as front/back. If Anki offers an option to update existing notes, choose it so the GUID column can prevent duplicates.

Current Limitations

• Basic question/answer text cards only
• No direct .apkg or .colpkg import
• No media/audio/image import
• No cloze support yet
• No Anki scheduling or stats import
• Large decks may be slow because the plugin currently stores cards in a JSON database

Recommended deck size for this beta is under about 1,000 simple text cards. Larger decks may work, but should be tested carefully.

Building From Source

Prerequisites

• Node.js 18+
• npm
• Android/JDK setup compatible with the Supernote plugin template

Build

npm install
./buildPlugin.sh

The plugin package is written to:

build/outputs/Flashcards.snplg

If you rename the package, clear old files from build/generated/ before rebuilding. The Supernote plugin loader can pick up stale bundles if multiple bundle files are present.

Development Notes

• The original stable base plugin is tagged as working-flashcard-plugin-base.
• The first beta with Anki text import/export is tagged as v0.1.0-beta.
• Persistent plugin data is stored locally on the device by a small native storage module.
• FSRS scheduling is handled inside the plugin using ts-fsrs.

License

MIT

A new plugin for Supernote that supercharges your link management. Generate interactive index pages of all links inside a note, create external web links, link to specific pages of other note files seamlessly, and manage broken links with ease.

Links plugin

https://github.com/taoist22/sn-links

Features

- Links Index Generation: Scans the current note for all links (text links, stroke links, and web links) and generates a clean, tappable index list right on the page.

- Advanced File Linking: Pick any `.note` or `.pdf` document on your device and create a link to it.

- Page-Specific Jumping: Automatically fetches the total pages of the selected note and lets you precisely choose which page to jump to using a visual selector.

- Absolute Routing: Fixes native Supernote limitations to guarantee that links to external notes always land on the correct page.

- Web Links: Drop fully functional URLs directly into your notebooks.

- Broken Link Management:

- Automatically identifies links pointing to files that have been deleted or moved.

- Repair: Visually re-map broken links to their new file destinations without having to recreate the link from scratch.

- Delete: Safely scrub orphaned links off your pages.

Installation

1. Connect your Supernote to your computer or use the Supernote Cloud/Partner App.
2. Copy the `Links.snplg` file into the `MyStyle` folder on your Supernote device.
3. Install the plugin on your Supernote device by going to `Manage Plugins` and selecting `Links`.

Usage

Once installed, you can launch the plugin at any time from the Plugins menu.

1. Generating an Index

- Navigate to a blank page in your note where you want your table of contents to live.

- Open the Links plugin and select the **Links page** tab.

- Tap **Insert Links**. The plugin will scan the entire notebook and drop a perfectly aligned, interactive index of every link onto your page.

2. Creating Web Links

- Go to the page where you want to insert a URL.

- Open the plugin and select the Web link tab.

- Type or paste your URL (e.g., `https://google.com\`), give it an optional readable label, and tap Add.

3. Creating File Links

- Select the File link tab.

- Tap Select File to browse your Supernote's storage for the target document.

- Use the horizontal page chips to pick exactly which page the link should jump to. (If you want to just open the file to its last-read page, you can delete the page number entirely).

- Give it a label and tap Add.

4. Fixing Broken Links

If you move or rename a file, any links pointing to it will break.

- Open the plugin to the Links page tab. It will immediately warn you if any broken links exist in the current note.

- Tap Repair to select the file's new location, or tap Delete to cleanly remove the dead link from your notebook.

Weather for Supernote

https://reddit.com/link/1tx2al2/video/l719nmrzqc5h1/player

A Supernote plugin that looks up the current weather for your location and inserts it into your note as an editable text stamp. Powered by the free, keyless Open-Meteo API.

Features

• City search — type a city name and pick from the matching results; no coordinates needed. Your choice is saved for next time.
• Current conditions — temperature, weather description, "feels like", wind speed + direction (16-point compass), and humidity.
• Two formats:
  • Multi-line (default):Toronto, Ontario · 2026-06-04 14:30 12°C, Slight rain · feels 10°C Wind 14 km/h NE · Humidity 78%
  • One-line: Toronto · 12°C, Slight rain · Wind 14 km/h NE
• Optional timestamp: toggle a date + local-time stamp on or off, in 24-hour or 12-hour format. The time is the reading's time in the location's own timezone.
• Units: °C / °F and km/h / mph, selectable and remembered.
• Position: Top Left or Top Right of the page.
• Inserted as an editable text element — lasso and move it like any text box.

Installation

1. Download Weather.snplg from the latest release.
2. Connect your Supernote to your computer using the Supernote Partner app or Browse & Access.
3. Copy Weather.snplg into the MyStyle folder on your device.
4. On your Supernote, open a note, tap the plugin icon in the toolbar, go to Manage Plugins, tap Add Plugin, and select Weather.

Usage

1. Open a note and tap the weather icon in the toolbar.
2. First run: search for your city and tap the correct match (e.g. "Springfield, Illinois, United States"). The location is saved.
3. The panel fetches the current weather and shows a live preview.
4. Adjust temperature (°C/°F), wind (km/h / mph), format, and position as desired. Changing units re-fetches; your settings persist.
5. Tap Insert to place the stamp and close the panel.
6. To switch cities later, tap Change on the weather screen.

Requirements & limitations

• NOTE files only. Insertion uses the note text-box API, which is not available in documents (DOC).
• Needs an internet connection at the time you fetch. The Supernote has no GPS, so location comes from your saved city search (not your physical position). Weather is current as of the last fetch.
• Weather data and forecasts by Open-Meteo.com, licensed under CC BY 4.0.

Building from Source

Requirements: Node.js ≥ 18, JDK ≥ 19 (Zulu 21 recommended), Android SDK 35.

npm install   # or: yarn install
./buildPlugin.sh

This plugin bundles a native module (AsyncStorage) for saved settings, so the first build requires two runs (PackageList.java is generated on the first and populated on the second). The built plugin will be at build/outputs/Weather.snplg.

Compatibility

Requires Supernote firmware with plugin support. Tested on Supernote Nomad (A6X2) and Manta (A5X2).

List sorter plugin

sn-list-sorter

https://github.com/taoist22/sn-list-sorter/releases/tag/v1.0.0-beta

A Supernote plugin that sorts a recognized or typed list alphabetically and inserts it back onto the page with your choice of formatting. Handwritten items must be converted to text using Recognize as Text before the plugin can read them.

Pre-release: This plugin requires the Supernote beta firmware and is not yet intended for general use.

How to Use

Step 1 — Recognize your handwriting as text

The plugin works on text the device has already recognized, not raw ink strokes.

1. Write your list items on the page (one item per line works best)
2. Lasso the handwritten items
3. Tap Recognize as Text in the lasso menu

The device will convert your ink to typed text in place. You will see the items redisplayed as a text block.

Step 2 — Sort and format

1. Lasso the recognized text block (or blocks)
2. Tap the List Sorter plugin button in the lasso menu
3. The plugin reads the items, sorts them alphabetically, and shows the Sort Panel
4. Configure your options (see below)
5. Tap Insert Sorted — the sorted list appears on the page below your original selection

Sort Options

Format

Adds a prefix to each item in the sorted list.

Alignment

Sets the text alignment within each box: Left, Center, or Right.

Font Size

Choose from 24, 28, 32, 36, or 40 pt.

Style

Toggle Bold on or off.

Insert As

This is the most important setting. It controls how the sorted list is written to the page.

Single box

All items are placed in one multi-line text box.

• Enables H (Highlight/Title) — lasso the box and tap H to add it to the Navigation panel as a title or keyword
• Enables New Event and New Task from the lasso menu
• The whole list moves and resizes together
• Use Format Group later to change font size or bold

Individual items

Each item gets its own text box, stacked vertically.

• Each item can be moved independently
• Use Realign to snap all items back to the same left edge with consistent spacing after moving them around
• Use Format Group to resize or restyle all items at once
• Does not support H highlight, New Event, or New Task on the group as a whole

>

Group Actions

Once a sorted list is on the page, lasso any item in the group and tap the List Sorter plugin button. The plugin detects that it created those elements and shows the Group Panel instead of the Sort Panel.

Realign

Snaps all items in the group to the same left edge and restores even vertical spacing. Useful after you have moved individual items around and want to tidy them up.

Only available for Individual items output.

Format Group

Changes the font size and bold setting for every item in the group at once, and repositions them with the correct spacing for the new size.

1. Tap Format Group to expand the options
2. Choose a font size and toggle bold
3. Tap Apply Format

Tips

• Original list stays on the page. The plugin inserts the sorted list as new elements; it does not delete your original recognized text. Delete or move the original manually once you are happy with the result.
• Undo. Use the back arrow (undo) if an insert does not look right. The plugin writes elements in a single operation so one undo removes the whole list.
• Borders and backgrounds. The SDK does not currently support filled backgrounds on text boxes. If you want to visually separate a list from page lines, consider moving it to a blank area of the page.
• Writing on top of an H-highlighted list. Once a single-box list is highlighted with H, the pen input is captured by the text box. This is a platform behavior, not a plugin limitation.

NEW RELEASE!
https://github.com/taoist22/sn-restyle/releases/tag/v0.2.0-beta

New features

• Presets — save up to 4 user-defined color + thickness combinations for one-tap access; presets persist across sessions
• Undo — after applying a restyle, the next plugin open offers a one-tap undo to revert all changed elements; available within the same session
• Geometry support — restyle now works on drawn shapes (geometry) as well as freehand strokes
• H-element protection — plugin detects notes with H (title/outline) elements and shows a clear disabled message instead of risking element corruption

Fixes

• Thickness input keyboard no longer covers the Cancel/Apply buttons

Limitations

• Undo is in-session only; closing the note clears the undo history
• Plugin is disabled on notes containing H (title) elements — use notes without H elements

I made this plugin because I wanted to reformat my handwritten notes to add emphasis without having to re-write certain sections completely.

**Does not work well with notes that have H headers, placement is unstable.

Restyle is a plugin for the Supernote Nomad and Manta that lets you change the ink color and stroke thickness of handwriting you have already written. Lasso any strokes on the page, tap the Restyle button, pick a color and thickness, and apply — the selected strokes are updated in place with no repositioning.

Features

• Four ink colors — Black, Dark Gray, Light Gray, and Ghost (white / invisible on white paper)
• Lasso any strokes — works on freehand handwriting anywhere on the page
• Non-destructive — strokes stay exactly where they are; only color and thickness change
• Works on Nomad and Manta

Installation

1. Download Restyle.snplg from the latest release.
2. video posted here: https://github.com/taoist22/sn-restyle/blob/main/README.md
3. Connect your Supernote to your computer using the Supernote Partner app or Browse & Access.
4. Copy Restyle.snplg into the MyStyle folder on your device.
5. On your Supernote, open a note, tap the plugin icon in the toolbar, go to Manage Plugins, tap Add Plugin, and select Restyle.

Usage

1. Open a note and lasso the strokes you want to restyle.
2. Tap the Restyle button in the lasso toolbar.
3. The plugin reads your selection and shows the Restyle panel.
4. Tap a color swatch to change ink color, and use the − / + buttons (or type directly) to adjust thickness. It is easier to make larger jumps in thickness by typing over the number than trying to use -/+ .
5. Tap Apply — the selected strokes are updated and the page reloads.

• Financial IRR / NPV: the full cash flow schedule and result
• Financial Amortization: periods, principal, interest, and remaining balance
• Conversion: category name, from value and unit, to value and unit

Smart placement detects the lowest existing element on the page and inserts below it.

Installation

1. Download SnCalc.snplg from the latest release.

Usage Notes

• This is a beta release. Verify critical results independently.
• Financial mode uses RPN (Reverse Polish Notation). Values are pushed onto a 4-register stack (X, Y, Z, T).
• The DEG/RAD indicator appears in the top-left of the Scientific display.
• The memory indicator (M) appears in the display when the memory register holds a non-zero value.

Update to the Calculator plugin:
Added Financial calculator and Scientific calculator modes

These new function have been *lightly* tested. Please let me know if you have issues or suggestions!

Three Modes

• Standard: A familiar algebraic calculator for quick daily tasks, featuring an ergonomic 5-column layout with percentage support.
• Financial (HP 12C Logic): A full-featured RPN financial engine. Calculate TVM (Time Value of Money), Amortization (Principal/Interest breakdown), IRR (Internal Rate of Return), and NPV (Net Present Value).
• Scientific: A dense 7-column algebraic grid featuring over 50 functions, including hyperbolic trigonometry, logarithms (ln, log10, log2), powers, roots (including custom root solvers), and scientific notation.

Smart Audit Trails

• "Full Record" Stamps: Beyond just results, SnCalc Pro can stamp detailed reports into your notes.
  • Amortization: Stamps a formatted block showing periods, principal paid, interest paid, and remaining balance.
  • Cash Flows: Stamps your entire investment schedule (CF0, CFj, Nj) alongside the IRR/NPV results.
  • Scientific: Stamps the full algebraic expression and the result.
• Smart Placement: Automatically detects the lowest element on your page and places the stamp below your handwriting, ensuring no overlaps.

High-Precision Engine

• Deterministic Math: Uses a custom recursive descent parser for algebraic expressions and the Newton-Raphson method for financial roots.
