Hey Product Hunt 👋
I’m Ujjwal, the solo developer behind BrainLoom.
For years, my study workflow was a mess. I was drowning in PDFs, typing notes in one app, and manually creating flashcards in another. I realized I was spending more time managing my tools than actually learning.
BrainLoom is a Learning OS designed for speed.
The core magic is the Flash-Loom: You simply highlight text in a PDF, and it converts into a Flashcard instantly. No copy-pasting. No switching apps.
It also features:
- 🎨 Infinite Canvas: Don't just list notes; weave them. Use "Smart Paste" to structure ideas visually into mind maps without touching your mouse.
- 🔗 Deep Context: The "Killer Feature." Click "View Source" on any card to jump back to the exact paragraph where the idea was born.
- 🚀 Active Recall Engine: A built-in smart scheduler that manages your reviews, so you master topics efficiently.
💻 Platform Update:
It is Windows Only right now. I know many of you are on Mac—I am working hard to port it!
I built this because 'Alt-Tabbing' was ruining my focus.

Pretty UX/UI :))

@busmark_w_nika Thanks Nika! 🙌 That means a lot coming from a design pro. I really tried to keep it clean and distraction-free.
I see you have a launch coming up on the 28th—I just followed your profile so I can support you when you go live! :)

@ujjwalranga That's so kind move from you. Than you so so much!
Congrats on the launch! I really really like how clean and uncluttered this looks, it gives a very nice “workspace” vibe.
At this early stage, what part of the experience are you most curious to see people use or react to first?
I'm impressed by BrainLoom's local-first approach and how it connects PDF highlights directly to flashcards with source context—it's exactly what I need to stop juggling multiple study apps—but I'm curious, does it support spaced repetition algorithms like Anki, and will there be any sync option for studying across devices?
BrainLoom
@geng_zheng Glad the workflow clicked for you! Yes, I built the FSRS v6 algorithm directly into the app (no plugins needed), so the scheduling is actually more efficient than Anki's default. Regarding Sync: I kept v1.0 strictly local-to-device for speed and privacy, but optional Cloud Sync is at the top of my roadmap for v2.0!

@zeiki_yu Thank you so much! 🙌 That means the world to me.
I'm curious—since you tried it out, did you get a chance to test the 'View Source' button on a flashcard? That's the feature I'm most proud of.
Very useful product with good UI/UX. Can I know which stack did you use?
BrainLoom
@szymcode Thanks! I poured a lot of love into the design, so I appreciate that.
The stack is Flutter & Dart. For the database, I used Isar (it's blazing fast for local storage).
The UI looks fantastic, and I'm particularly impressed that you're building with Flutter—I've been using it for the past 6+ years myself and love how rapidly it's evolving.
Out of curiosity, what platform are you using to handle subscriptions and payments? How much do they charge per subscription?
BrainLoom
@nikhil_sharma_117 Thanks, Nikhil! Fellow Flutter dev here 🤝. It really has matured into a beast for desktop apps.
For payments, I decided to go with Lemon Squeezy. As a solo dev in India, dealing with global taxes (VAT/GST) is a nightmare, and they handle the 'Merchant of Record' compliance for me. They charge 5% + 50¢ per transaction
@nikhil_sharma_117 @ujjwalranga You maybe want to consider adding BrainLoom to LS Affiliate program, too. Setup is really simple and maybe it can help growth...
