BrainTube vs Glasp
Social highlights vs. private intelligence.
Glasp is a social web highlighter — you mark text on articles, optionally share it publicly, and discover what others highlight. BrainTube is a private, AI-queryable knowledge base. Glasp's value is the social discovery layer; BrainTube's value is depth (transcripts, summaries, semantic search) and MCP-level integration with the AI clients you actually work in.
Glasp turned highlighting into a social network. BrainTube treats highlighting as one input into a private, AI-queryable knowledge base — with first-class video, summaries, and MCP integration into the AI tools you use every day.
BrainTube
- Private by default — your library, your retrieval
- Full video and audio transcripts, not just text snippets
- AI summaries and chapters auto-generated per item
- Hybrid search you can actually use from any AI client
- Public sharing optional — Brains, Digests, Notes
- MCP server — Claude/Cursor/ChatGPT query directly
Glasp
- Optimized for social — public-first feels weird for personal notes
- Web articles only; no native video or audio capture
- AI features are summarizer-wrappers, not corpus retrieval
- No MCP / no AI-client integration
- Search is over your highlights, not the underlying corpus
- Discovery feed is the headline; storage is the side effect
When you want a private knowledge layer that AI clients can query — and you consume video as well as text.
When the social discovery of what others highlight is the actual reason you're there.
A real scenario
A writer enjoys Glasp's social feed to see what other people are reading. The same writer keeps her real research private and consumes hours of podcasts a week. BrainTube takes the podcasts, articles, and PDFs into a private corpus the writer queries through Claude — and Glasp stays open in another tab for the social side.
Verdict
Use Glasp for social highlights. Use BrainTube as your private, AI-queryable knowledge layer.
