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.
What is the one part of your current study routine that frustrates you the most? Let me know in the comments
Congratulations on the launch; without a doubt, it is a tool that every education professional could use. The features look interesting and, besides saving time, I believe they will increase productivity when studying, which will lead to better results. It seems to me that it could become an essential resource for those looking to optimize their teaching and learning methods. It would also be interesting to know if there are customization options to adapt it to different educational styles. Undoubtedly, this type of tool can make a big difference in the academic field.
Does the tool work on any operating system (Mac, Linux, Windows)? Is the interface only available in English? I ask because there are many of us who do not master that language, and an interface in Spanish or another language would be very useful.
Are you planning to launch any version for mobile devices?
Also, I would like to know if you have plans to add support for more languages in the near future, as this would undoubtedly expand its accessibility and usefulness globally.
Thank you!
BrainLoom
@alejandro_luna2 Thank you, Alejandro!
OS: Windows now. Mac/Linux coming in ~4 weeks.
Mobile: On the roadmap for later this year.
Language: The interface is English v1.0, but you can create notes/cards in Spanish/any language immediately. UI localization is coming in Q3!
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!
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...
Congrats on the launch Ujjwal! This looks really helpful. Also are you planning to accommodate other sources apart from PDFs like web articles, ebooks or Youtube videos?
BrainLoom
@mustassim Thanks, Syed! The short answer is: Yes.
Full web-article parsing (like a 'Reader mode') is next on the roadmap for Q2. Is there a specific source you use most often for study (e.g., Coursera, Wikipedia, Blogs)?"
Congrats on the launch! One feature that I personally will be excited about is automatically filtering out any content that is duplicated across multiple pdf files, curious is that is something you are considering
BrainLoom
@david_chen37 Oh, that is a brilliant idea for v2. Cross-PDF deduplication is tricky but would be a killer feature for researchers handling multiple papers. Adding it to the wishlist!
