Khoj
App in the BluixApps catalog
What it is
Khoj is a personal AI assistant that searches your notes, documents, and the web — answering questions in chat with citations from your own data. Self-hosted, with native clients for Obsidian, Emacs, browser, mobile. Khoj indexes Markdown, PDF, images, org-mode, and chats with the content via any LLM.
It's the "personal Perplexity" — your second brain made conversational, on your infrastructure.

- Document Q&A — ask questions about your PDF library

Tips & operations
- Pair with Ollama for fully offline personal AI — no notes leave your network
- Index incrementally — bulk import of large note libraries takes time; let it run
- Set rate limits — public-facing instance can be abused; cap queries per user
- Persist
/data— index + embeddings live here; mount volume from day one - Memory usage — indexing large note libraries needs more RAM than runtime; size accordingly
- Update notes via API — Khoj watches filesystem; bulk changes need re-index via API
