Semantic Scholar is a free academic search engine. Fynman is a local workspace that organizes, synthesizes, and writes over the library you build. An honest, sourced comparison.

Semantic Scholar is a free, enormous academic search engine with a solid citation graph and API — one of the best places to find papers.
But it’s a search engine, not a workspace: it doesn’t organize your library, synthesize across your papers, or help you write. And its coverage of paywalled work, books, and patents is thin.
Fynman is the workspace half: import what you find, surface gaps, synthesize across your own collection, and draft — locally, on your own AI key. Here’s the side-by-side.
Every row checked against the tool's docs and user reviews. Toggle to focus on where they actually differ.
