No complex setup. No learning curve. Just capture your knowledge before it fades.
Finish a course, solve a problem, read a paper — any 'aha' moment worth preserving.
Grab your phone or screen recorder. Explain it like you're teaching a friend. 5-15 min is enough.
Upload to YouTube as unlisted. Paste the link in Knowledge Capsule under the right topic.
Years later, search your capsule and hear past-you explain it — with all the context intact.
Every feature exists to help you capture, organize, and rediscover what you've learned.
Group recordings by subject — DSA, System Design, ML, anything. Your knowledge stays organized by what you were learning, not when you learned it.
Auto-generate searchable summaries from your recordings' transcripts. When you need a quick refresher, read before you re-watch.
Watch your past self explain concepts directly in the app. No context switching, no searching YouTube.
Archive topics you've moved past. Restore anytime, or permanently delete only from archive.
Single-user capsule. No sharing, no public profiles. Your videos and notes stay private.
Edit titles, notes, and summaries right where you see them. Add timestamps and annotations.
That moment of clarity is fleeting. Knowledge Capsule helps you capture it in your own voice, so you can come back to it whenever you need — whether that's next month or five years from now.
Every recording is a gift to your future self. The best time to start was yesterday. The next best time is now.
