Feynman - AI Research Assistant

The AI-plugin space here is crowded, so here is the short version of how Feynman differs and how it handles your data.

Most AI plugins are chat-with-your-vault. Feynman is an agent that runs multi-step workflows and leaves you files. You run /lit, /deepresearch, /audit, /review and others from the chat panel or the command palette. Output lands as regular markdown in Feynman/outputs/, Feynman/notes/, and Feynman/papers/, so everything it produces is a normal note you can link, edit, and keep.

On data handling, since that is usually the first question:

  • The agent runs in a Docker container on localhost. Nothing about your vault reaches a server I run. There is no managed tier in v1.

  • Your Anthropic API key is stored at ~/.feynman/secrets.json, outside the vault. Obsidian Sync does not touch it.

  • The loopback server requires a random bearer token, so other processes on your machine cannot reach it.

Requirements: Obsidian 1.5+, Docker Desktop, an AI model API key or OAuth login. Desktop only for now. You pay your own API usage. MIT licensed, and early, so I am looking for feedback.
