YouTube knowledge brain — ingest, classify, and curate your YouTube activity

yt-brain

Turn passive YouTube watching into active knowledge.

yt-brain ingests your YouTube watch history, classifies videos by genre and channel, and provides an interactive dashboard to explore your viewing patterns.

Features

• Semantic search — find videos by meaning, not just keywords (powered by sentence-transformers + sqlite-vec)
• Genre classification — automatic categorization using YouTube categories and keyword analysis
• Interactive dashboard — filter by genre, channel, time range, and starred channels simultaneously
• Incremental sync — stay current with new watches via yt-dlp browser cookie integration
• AI-powered clustering — discover viewing patterns with HDBSCAN + Claude-generated topic names
• Google Takeout import — bulk import your full watch history

Install
