I’m building Penlog, a handwritten iPad journal for people who use software.

The thing I kept wanting was simple: I like planning by hand, but the rest of my day lives in tools — Notion, calendar, Claude, ChatGPT, task databases. My handwritten page was the one place none of that software could really see.

So Penlog starts with a normal daily journal page. You write with Apple Pencil. As you write, Penlog picks out tasks, and notes, keeps the original page attached, and lets the useful pieces show up in the tools you already use. Each morning you can seed the day's page with your latest open tasks and calendar events.

What’s working now:

• handwriting (even my chicken scratch) converted and stored as text

• tasks and notes pulled out of the page

• two-way Notion task sync

• the original handwritten page stays as the source

• API / MCP access so agents can read your journal too

It’s in TestFlight now, free during beta. iPad + Apple Pencil required.

I’m curious how other people handle this today: if you think or plan by hand, does that writing make it back into your software anywhere — or does it mostly stay trapped on the page?

Anyone else write notes on iPad but manage tasks in Notion? I built something for that.

I'm building Penlog for people who think on paper but live in Notion.

The basic idea: write naturally with Apple Pencil, and the things you wrote — open tasks, meetings, scratch notes — show up in Notion without you retyping. The original page stays as the source.

I built it because handwriting is how I plan. My prior workflow was the standard one: GoodNotes export, PDF into Notion, Notion AI to pull the text out, tasks created by hand. The page lost something in the round-trip. Penlog turns that into one step.

What's live today:

• every page is searchable by what you wrote — Penlog reads it as you're writing

• tasks, events, and notes are pulled into structured pieces

• tasks sync two-way to a Notion database (toggle done on either side, the other updates)

• the original page stays attached so you can always go back to your own ink

Worth noting alongside this: Notion's Developer Platform release this week — External Agents, native MCP, the new Workers runtime — is explicitly opening Notion up to tools that turn external context into something Notion can read. Penlog's pen-to-structured-data flow is the input shape for exactly that.\

In TestFlight now, free during beta. iPad with iPadOS 17+ and an Apple Pencil.

Curious if anyone here is hand-writing into Notion today — what does your path look like? GoodNotes → PDF → Notion AI was the one I knew best, but I'd bet there are other patterns I haven't seen.

Anyone else write notes on iPad but manage tasks in Notion? I built something for that.

I’m working on a small app called Penlog for people who like writing notes by hand — especially on iPad with Apple Pencil — but still use Notion as their actual system of record.

The idea is simple: you keep writing naturally, and Penlog turns your handwritten pages into searchable notes and Notion tasks automatically.

I built it because I kept running into the same problem: handwriting is great for thinking, planning, and journaling, but terrible for follow-through. Tasks, decisions, and useful ideas get buried unless I manually export a PDF and upload them into Notion later — which I almost never do consistently.

Penlog is meant to bridge that gap. It reads handwritten pages, finds the action items, keeps the original notes searchable, and syncs tasks into Notion so they actually land where work happens.

It’s still early, but I’m looking for a few Notion users who already take handwritten notes on iPad and would be willing to try the beta and give blunt feedback.

Curious if this resonates with anyone here. If you write by hand but manage your life/work in Notion, how are you handling that gap today?
