🤔 Why Weaver? (NotebookLM vs Weaver)

Tired of Google NotebookLM's limitations? Weaver is a free, open-source NotebookLM alternative that you can self-host and customize.

Feature	Google NotebookLM	Weaver
Open Source	❌ Proprietary	✅ AGPL-3.0
Self-Hosted	❌ Google Cloud only	✅ Deploy anywhere
Visual Canvas	❌ List-based UI	✅ Infinite canvas workspace
LLM Choice	❌ Gemini only	✅ Any LLM (Claude, GPT-4, Gemini, Ollama)
Video Sources	YouTube only	✅ YouTube + Bilibili + Douyin
Data Privacy	⚠️ Google servers	✅ Your data, your servers
API Access	❌ None	✅ Full REST API
Cost	💰 Usage limits	✅ Pay only for LLM API

Weaver = NotebookLM + Miro + Obsidian — All in one open-source package.
