of everything you learn vanishes within 48 hours. That video, article, podcast? Gone.

Not an app. A knowledge layer.
Three steps from what you save to what you build — accessible from every AI tool you use.
Layer 1
Your Raw Universe
Videos, documents, articles, podcasts — all searchable, all transcribed. Connect up to 6 YouTube accounts.
What no other tool does.
From frictionless capture to universal access — every feature serves one idea: the knowledge you save should work for you, in every tool you use.
YouTube Auto-Sync
Connect your YouTube account and we automatically capture every video you watch. Zero effort, total recall. No competitor does this.
Knowledge Playground
Explore connections between all your content on an interactive knowledge graph. Chat, annotate, and quiz — deeper than any competitor.
Content Lab
Generate articles, images, and even music FROM your knowledge base. No other tool turns your saved content into new creations.
Semantic Search
Search by meaning, not keywords. Ask 'how to stay focused' and find the exact moment — even if those words were never said.
Spaced Repetition
Science-backed retention with adaptive review scheduling. Don't just save knowledge — actually remember it. The layer competitors lack.
Audio Digest
Listen to AI-generated audio briefings compiled from your library. Turn your commute into learning time — across everything you've saved, not just today's reading.
