Khoj

★ 32k

Your personal AI second brain — chat with your notes and documents, custom agents, runs locally or self-hosted.

Khoj does the job of ChatGPT Plus, Notion AI and Perplexity Pro, self-hosted. It is AGPL-licensed, so a hosted fork has to publish its changes, and setting it up is an afternoon, not a weekend. ChatGPT Plus bills $20 for it. 32k stars on GitHub.
