The honest brief
Connected Papers
A visual citation-graph map rather than a chat assistant — surfaces adjacent prior and derivative work a keyword search would overlook.

- Finds related work beyond keywords
- Built on the Semantic Scholar corpus
- Free tier with 5 graphs per month
- Affordable academic plan
- Free tier capped at 5 graphs/month
- Coverage limited to indexed papers
- Not a full-text reading or chat tool
Semantic Scholar
A free, nonprofit-run corpus of 200M+ papers with auto-generated TLDR summaries and an open API — no paywall or ads, unlike most research tools.
- TLDR one-sentence summaries for many papers
- Covers every field of science
- Semantic Reader adds inline citation context
- Adaptive Research Feeds for new work
- TLDR coverage skews to CS, bio, and medicine
- Not a chat/Q&A research assistant
- Metadata gaps for some niche fields
