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.

Turning PDF highlights into linked flashcards is powerful. How do students usually review or resurface those cards over time inside BrainLoom?

Indeed I like BrainLoom's local first concept! Just curious - how often does it refresh the local memory?

The "View Source" feature is genuinely killer - I've always hated losing context when reviewing flashcards weeks later. The fact that you built FSRS v6 directly into the app (not as a plugin) shows serious commitment to the learning science. As a fellow knowledge worker drowning in PDFs, the Smart Paste for mind maps without touching the mouse sounds like a huge time-saver. Is the Mac version planned for Q1 2026, or later in the year?

This seems like a very carefully made and well-made product. But with so many strong features, no feature truely stands out. I had previously tried using Google's learn-your-way and notebook LM. The thing with these tools is that the learning curve is steep, and it takes time for it to fully seep into your routine.

Project seems really useful. Though I already use obsidian. If I start using the app, how would the migration to your app looks like?
Really clever use of a unified learning OS turning PDFs into flashcards instantly solves a real chaos problem for students and researchers. Curious: are you seeing more value from flashcard generation or the deep context linking back to source text? That kind of behavior usually predicts whether people stick long‑term. �

converting highlightes directly into flashcards is going to save me hours of manual data entry every single week.

​Local-first is the way to go because I hate worrying about my study data disappearing or needing a constant internet connection to get work done

Spaced repetition lives or dies on scheduling, how much control do users get there?

Local-first is refreshing, but how do you see syncing or backups fitting in log term without compromising that philosophy?

Alt-tabbing between PDFs, notes, and flashcards is painfully real. This feels built by someone who actually studies, not just ships features.

The view source jump-back is huge. Flashcards without context always felt shallow this actually close that gap nicely.

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!

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

Amazing man! It's the way I use to learn content so you're helping enough with it. Hope everybody can see the same and wish you all the best here!

Kudos on Launch. The “view source” context jump is 🔥, feels genuinely built by someone who studies a lot.
