asta-paper-finder vs feynman
Research paper discovery and AI research workflows compared
asta-paper-finder finds and ranks papers from a single natural-language query, while feynman is a command-line agent for broader research tasks such as literature reviews, paper critique, and source comparison. asta-paper-finder is a frozen Python evaluation release; feynman is a TypeScript tool that runs on Pi and requires a configured model provider.
asta-paper-finder: Find Papers from Natural-Language Queries
PaperFinder is a single-query research agent that finds papers using content and metadata criteria, then judges and ranks results. This frozen evaluation release is suited to reproducing results or running the core workflow locally, rather than replacing the live service.
feynman: Research Papers with an AI Agent
Feynman is a TypeScript CLI agent for investigating research topics, reviewing papers, and comparing sources. It suits researchers and developers who want structured, citation-aware literature work and can configure a model provider.

Key differences
- asta-paper-finder focuses on single-query paper search and ranking; feynman supports a wider set of research workflows, including literature reviews and draft reviews.
- asta-paper-finder evaluates retrieved abstracts and snippets against query criteria; feynman uses researcher, verifier, reviewer, and writer agents, with provenance files for selected workflows.
- asta-paper-finder is written in Python and licensed under Apache-2.0; feynman is written in TypeScript and licensed under MIT.
- asta-paper-finder exposes a FastAPI endpoint and requires credentials for OpenAI, Semantic Scholar, Cohere, and Google; feynman is a CLI that runs on Pi and requires a model provider.
- asta-paper-finder is a frozen snapshot that may differ from the live service; feynman is not archived and describes citation checks and provenance for some workflows.
Choose asta-paper-finder if you…
- need a locally runnable, single-query paper-search workflow for evaluation or reproduction.
