Auto-organized
Drop Anything. It's Auto-Organized.
Videos, PDFs, articles, podcasts — drop them and they're instantly in your second brain, auto-tagged and searchable.
- Paste a YouTube link — it's transcribed, summarized, and saved.
- Drop a PDF — AI extracts the key points and tags it by topic.
- Everything is auto-organized so you never have to manually file anything.
Stop organizing. Start knowing. Your knowledge base builds itself.

Search by Meaning, Not Keywords
Semantic search finds content by what it means, not just the words it contains. Finally find that thing you saved.
- Search: "That video about morning routines" — found, even if you never typed those words.
- Search: "What I learned about focus" — shows all relevant saves across formats.
- Find anything from your entire library in seconds.
Search like you think. Semantic search understands what you're looking for.
