Hey people,

If anyone saw my other post about converting scanned PDFs to EPUB, welcome back. I implemented a lot of features based on the feedback I got from the users, so check it out if you want. Anyways,

After building that, my friends said to me that they read a lot of stuff online[articles, newsletters, blogs] and bookmark them. They wanted a tool to read them offline, just the way they read their book, with a clean structure.

So I built a Chrome extension.

https://www.convert2epub.com/extension/

FEATURES

• Add the current page from the toolbar popup or the right-click menu
• Keep a running reading list; pages stay queued until you're ready to save
• Drag to reorder chapters before you export
• Give the book a custom title, or let it use the first page's title
• Cover image and in-article images are pulled in automatically
• Everything runs locally in your browser, no account, no external server
• Works great with long-form articles, blog posts, and documentation pages

HOW IT WORKS

1. Browse to a page you want to save and click "Add this page"
2. Repeat for every page you want in the book
3. Click "Save as EPUB"; your browser downloads a ready-to-read .epub file

Please try and tell me if you like it.

Hi everyone — we've been building Vikreya (https://vikreya.com) and we're opening it up publicly. It started as "why do I need a coupon app, a marketplace app, and a local-services app separately" and turned into one place for:

• Smart Deals — AI-powered search that surfaces real shopping deals
• Trades — buy/sell marketplace, free to list, no fees to browse
• Services — post a job, get quotes from local pros
• Rewards — earn points/cashback across all of it

It's still early and I'm sure there's rough edges — genuinely want to hear what's broken or missing.

Best regards

We built Shehnai Stories — https://shehnaistories.com

The idea is pretty simple:

Indian weddings spend an absurd amount of money on venues, clothes, photography, decor, etc.

Then the actual invitation that introduces the wedding is often… a generic PDF with floral borders, or a slideshow with floating Ganesh PNGs and random transitions.

So we’re building a studio specifically for high-end wedding invitation films and designed digital/PDF invites/digital websites.

Not “choose template → change names → export.”

The goal is for the invite itself to feel like a piece of the wedding — custom art direction, caricatures/illustration, animation, storytelling, music, culturally specific design, etc.

We’re mainly targeting Indian weddings, where there are also 4-7 different events apparently requiring their own identity.

Site is here:

https://shehnaistories.com

Please roast:

• Does the website immediately explain what the hell we sell?
• Does this actually feel premium or just like another wedding-template business wearing expensive clothes?
• Which part of the site looks amateur?
• Would you trust us with an important wedding invite?
• Is the positioning too broad?
• Is there anything that makes you think “why would I pay for this?”
• And most importantly: is this a real business, or have we successfully invented a solution to a problem nobody gives a shit about?

Don’t be nice. I’m posting here because friends and family are professionally useless at giving negative feedback.

Hey everyone,

I’ve been working as a commercial facility HVAC technician for years, and one recurring nightmare drove me to learn software development: tracking heavy mechanical hardware inside concrete vaults, hospital basements, and deep sub-levels.

Every enterprise CMMS or inventory tool on the market completely drops dead the moment you lose cellular service. On top of that, manual data entry while hanging off a ladder trying to read a corroded, sun-bleached nameplate is completely impractical.

I built Equipment Tracker Pro to solve the exact headaches we face in the dirt.

The core architecture runs on a localized SQLite engine that caches everything locally on-device. It updates and logs completely offline, then executes a smart-sync state change with a Firebase backend only when you walk back out to the truck and hit signal.

To kill the keyboard friction, I integrated a multimodal Gemini AI scanning layer. You snap a photo of a weathered data plate, and it extracts over 40 structured database fields (Compressor RLA/LRA, MCA, MOP, factory chemical charge weights, belt codes, and filter sizes). It also automates EPA Section 608 leak-rate math configurations for heavy commercial industrial charges and handles native thermal printing layouts for on-site QR asset tagging.

The core logging frameworks are completely free because bottom-up technician adoption matters more than corporate walls.

The web platform documentation and details are fully accessible directly via our main domain portal at: https://equipment-tracker.com

I am also launching a Product Hunt community queue this Tuesday to gather raw UX feedback from other developers and field engineers.

Would love to know your thoughts on the offline-first sync architecture or the edge OCR accuracy limits if you've built similar tools!

Solo dev here. I kept owning things and forgetting where I put them, so I built Store & Forget.

The whole point is zero effort to catalog: you don't type or tag anything. Snap a photo and it auto-fills what the item is (the photo scan uses a cloud AI service). Later you find it by searching names, descriptions, or which box or room it's in, or tap "Smart Find" to search by meaning.

Local-first: everything sits in an on-device database, no account, no sign-up. Optional backup to your own Google Drive.

It's free, Android only. Would love feedback from other builders.

Founder disclosure: I built MGO Data and its DT model.

DT handles most of the work automatically:

- Audits the store

- Diagnoses technical SEO and AI-visibility issues

- Prioritizes what should be addressed

- Creates individual tasks

- Drafts supported fixes

- Sends them for merchant approval

- Applies supported Shopify changes

- Checks the live result

- Rolls back failed or conflicting changes

The merchant does not have to understand every SEO term or manually turn an audit into a

plan. Approval is required before DT changes the store.

Current automatic Shopify writes include supported SEO titles, meta descriptions, and

eligible sitewide JSON-LD. Content and FAQ tasks can be planned, but full content

publishing is not automatic yet.

DT also has an advertising lane that turns business goals, economics, offers, and creative

assets into structured Meta, Google Search, and TikTok campaign plans. It prepares

campaign and ad-set structures, including supported Meta CBO/ABO decisions, checks

tracking and account readiness, and places actions behind approval.

I am not claiming guaranteed rankings, AI citations, or proven advertising performance.

Real ad-account execution is still being validated.

MGO Data is currently free to test. I want completely open feedback about anything useful,

incorrect, confusing, missing, unnecessary, or difficult to trust.

Hey guys,

A couple months back i shared my local pdf editor here (the one that keeps your original fonts intact when editing). The feadback from you guys was insane, and alot of people reached out asking for way more than just simple text editting.

So I basically spent the last few months rebuilding it into a full PDF suite for V2!

Heres whats new in this version:

• Upgraded Studio + OCR: added in-browser OCR so you can finaly edit scannned docs. Completely redid the rendering engine for crisp exports and loaded the toolbar with tons of layout options.
• Pro Sign: real encrypted signatures. Not just slapping a transparent png on top like most sites do, but actual encrypted signature standards right inside your browser.
• Standalone Tools: built dedicated utilities outside the main editor (Word-to-PDF, compress, redact, protect, etc) so no need to rely on sketchy converter sites anymore.

Also quick update: the Android version will be availible on Google Play later this week!

The main philosophy is still teh same: 100% local, zero files uploaded to any server, no account needed, and no paywalls.

Just pushed the update live today. Since theres a ton of new stuff under the hood, there might still be some small bugs here and there... if anything acts weird on your end, let me know in the comments and ill fix it asap!

Cheers PdfNoLimit

I started a watch review site to learn Amazon affiliate marketing properly. What I learned instead was that writing reviews is the small half of the job. The big half is product data, keeping prices and stock accurate across three Amazon marketplaces, images, structured data, hosting, and the endless small repairs. Most people who want a site like this quit at that layer, not at the writing.

So I built usebravery, which does that half for you.

How it works: you pick a category (watches, coffee gear, mechanical keyboards and a dozen more), we build the site on your own domain, fill it with products, keep prices and stock current, and handle hosting, content and updates. The links carry your own Amazon Associates ID, so commissions are paid by Amazon directly to you. We charge a monthly fee and never touch your commissions.

Markets are Amazon US, UK and Germany. Plans start at $29 a month for the US market, with UK and Germany on higher tiers. There is a 7-day free trial: a card is required but you are charged nothing during the trial and can cancel from the panel with one click.

What I am not promising is earnings. Commission depends entirely on your traffic and Amazon's category rates, and anyone handing you a number is selling you something. My own watch site is three months old and still early. What you get from me is the site and the running of it, not a revenue guarantee.

One thing worth knowing if you are new to this: Amazon closes your Associates account if you do not make three qualifying sales within 180 days of signing up. It happened to me. That means the real first problem is not building a site, it is getting those first sales, which is why I offer to pick the starting products together on a call rather than dumping a category on you.

https://usebravery.com

I would genuinely rather hear the sceptical questions than the nice ones. This category is full of junk (Flippa flips, Fiverr spam, done-for-you scams), so if the whole idea sounds suspicious to you, tell me exactly where it breaks and I will answer straight. What would stop you from trying something like this?

So I built [Blog2Video](https://pdf2vid.com) \- so far it has generated over $4K in additional revenue almost all on autopilot.

\- It uses remotion for the video

\- It takes 3 min from link/upload->video

\- It has eleven labs voiceover + stock footage + AI image

\- It uses configurable human templates to base the video on.

Has a generous free tier, only costs $0.6 per video much more affordable than AI video models or video editors

I built AutoShelf, a macOS menu bar app that watches your folders and auto-organizes files based on rules. Think Hazel but simpler. And on the Mac App Store. And with MCP support so AI assistants can control it.

The pitch: set it and forget it. Downloads folder stays clean. Desktop does not look like a landfill. DMGs auto-delete after 3 days.

I am a solo dev. This is my first Mac app. I have been building it for about 8 months alongside my day job. It is on the Mac App Store for $19.99 one-time (no subscription). Free tier gets one rule. Pro unlocks everything.

It has:

- 13 file actions (move, copy, trash, rename, tag, archive, image optimize, convert, photos import)

- 12 condition types (file type, extension, download source, date, size, name)

- MCP integration so Claude/Cursor/opencode can create and run rules

- 9 built-in templates

- 19 languages

- A CLI tool (separate Go binary)

Current state: version 2.0.1. Working on 3.0 which adds custom conditions and actions.

Roast away. Tell me why this dies or what I am doing wrong. I can take it.

I've been building Discovery Companion as a side project and I'm at the stage where feedback from people who know me isn't enough.

It's designed around the work that happens during and after customer discovery: keeping customer context, opportunities, discovery, requirements and the resulting customer-facing documentation in one structured workflow.

https://discoverycompanion.app

Don't worry about being nice. I'd particularly like to know:

• Within 30 seconds, do you understand what it does?
• Who do you think the actual customer is?
• Does the problem feel real or manufactured?
• Does the workflow/product seem useful or overcomplicated?
• What would stop you creating an account?
• Does €24/month feel sensible, too high, too low, or irrelevant because you wouldn't use it anyway?
• What looks amateur, untrustworthy or confusing?

One thing I'd especially like to avoid is explaining the product myself and then hearing that it makes sense. I want to know whether it makes sense without me there.

For context only after you've had a look: the initial audience I have in mind is consultants and solution professionals working around CX, contact centres and CCaaS. I'd be interested to know whether you got anywhere near that from the product itself.

Roast away.

our friend group is split across spotify, apple music, youtube music and even vlc. theres no way to see what everyone is playing unless you're all on the same app.

so we started building vynu, an android home screen widget that shows what your close friends are currently listening to in a compass style view. designed to work across different music players.

its not a streaming app or a social network. just a small quiet widget for close friend groups who want to know what each other are playing.

we're still early and want to see if this actually resonates before we go all in. if you’d use something like this, join the waitlist at getvynu.com so we can measure demand.

would love honest feedback, would you actually keep this on your home screen?

I've been building a side project called Portlio over the last few months.

The problem I wanted to solve was simple: I kept finishing projects, pushing them to GitHub, and forgetting to update my portfolio. By the time I started applying for internships, my portfolio was already outdated.

So I built Portlio.

It lets you:

• Connect your GitHub account
• Choose which repositories to showcase
• Generate a portfolio website
• Add context about your projects
• Keep your portfolio updated as your GitHub changes

Some recent improvements based on community feedback:

• Demo mode (no GitHub login required)
• Multiple portfolio templates
• Better onboarding
• Faster page loads (mobile Lighthouse: 90 on the landing page)
• Improved GitHub sync flow
• Better project storytelling instead of just listing repositories

I'm not really looking for design feedback anymore—I want to know whether this actually solves a problem for developers.

A few questions:

• Do you maintain a portfolio, or has it become outdated?
• Would you trust GitHub as the primary source for keeping it updated?
• What would stop you from using a tool like this?

You can try the demo here without signing in:

https://theportlio.com

I'd appreciate honest opinions, especially from developers who've gone through internship or job applications. If you think this is solving the wrong problem, I'd rather hear that now than after launch.

So I built this directory for people to showcase their products. I wanna make it different for builders in a way that their product stays in public for a longer period of time rather than just a launch day. I've always come across this situation where waiting for months for the launch day still gets you ghosted. This is an approach to go beyond that and always have the products in front of the right people.

Also, builders who're truely in for making their product stand out, i've made a builder tier for them that really helps them stand out from the regular products. Pricing honestly feels like a deal.

I've also implemented analytics for people to see how they're doing on the platform.

For normal users to navigate through the platform, I've implemented semantic search. just give it a proper description on the search bar and look at it come up with the best products.

Currently with just a few products covering every category. I'm on a quest to grow this platform more and more.

I'd love for your to be genuinely unhinged on the UI/UX, Navigation, Pricing, Features, Everything.

Have spent months on Duolingo before moving to another country and realized that while I can say "the horse drinks milk," I have no idea how to ask a landlord about heating. Vocabulary is great, but there were just not any specific goals.

So I created something where you tell me your motivation — job relocation, partner's family, whatever — and we create the lessons tailored to that, rather than anything else. Normal course still exists if you just want to learn language.

Just wondering what you people think in this sub: does goal-oriented approach really work better, or should one start with boring basics first? Cannot make my mind up.

Built this because every affordability calculator I found only covered houses and cars, using generic income brackets instead of real numbers. Tell me what's wrong with it.

You type in what you're considering (a wedding, a business loan, IVF, "to take unpaid leave" - 800+ built-in categories, or your own) plus your income, and it gives a plain risk read - low, moderate, elevated, or high - instead of a spreadsheet. No sign-up needed.

What I'm least sure about: whether the risk thresholds themselves are right (is 15% of take-home too conservative for a car payment? too loose?), and whether "tight/risky" actually reads as useful or just vague.
