Feynman is an open source AI research agent that runs in your terminal. It searches academic papers, synthesizes evidence across sources, verifies citations, and replicates experiments — all from a conversational interface built on Pi and alphaXiv. Every output is source-grounded. Claims link to papers, docs, or repositories with direct URLs. You can ask naturally in free-form language or use slash commands to invoke specific research workflows.

​
Research subagents

Feynman ships four bundled research subagents that are dispatched automatically depending on the workflow:
  • Researcher — gathers evidence across papers, the web, repositories, and documentation
  • Writer — produces structured paper-style drafts from research notes
  • Reviewer — runs simulated peer review with severity-graded feedback and a revision plan
  • Verifier — checks inline citations, verifies source URLs, and cleans up dead links
The lead agent plans and delegates work; subagents handle decomposed subtasks and hand off results via files.

​
Research workflows

Ask Feynman in natural language or use slash commands as shortcuts. The table below lists the built-in workflows:
CommandDescription
/deepresearch <topic>Source-heavy multi-agent investigation with parallel researchers, synthesis, and verification
/lit <topic>Literature review with consensus findings, disagreements, and open questions
/review <artifact>Simulated peer review with severity ratings and a revision plan
/audit <item>Compares paper claims against the public codebase to surface mismatches
/replicate <paper>Replicates experiments on local or cloud GPUs
/compare <topic>Side-by-side source comparison matrix
/draft <topic>Paper-style draft from research findings
/autoresearch <idea>Autonomous experiment loop
/watch <topic>Recurring research watch on an evolving topic
/outputsBrowse all research artifacts (papers, outputs, notes)

​
How it works

Feynman is built on Pi for the agent runtime and alphaXiv for paper search, Q&A, code reading, and annotations. Research capabilities are delivered as Pi skills — Markdown instruction files synced to ~/.feynman/agent/skills/ on startup. Additional tools include Docker for isolated container execution, Gemini or Perplexity for zero-config web search, Modal for serverless GPU compute, and RunPod for persistent GPU pods.

​
Get started

Installation

Install Feynman on macOS, Linux, or Windows using the one-line installer, pnpm, or bun.

Setup

Configure your model provider, API keys, and alphaXiv authentication.

Quick Start

Launch the REPL, run your first research query, and explore slash commands.
