The honest brief
OpenEvidence
Official AI partner of NEJM and JAMA, so answers cite journal-grade licensed evidence other clinical search tools can't access.
- Free for verified U.S. clinicians
- Licensed NEJM/JAMA content partnerships
- Answers cite primary evidence
- Wide adoption among U.S. physicians
- Verified-clinician gate to access
- Weak at targeted author/journal lookups
- Curation process is opaque
- Overreliance risk for trainees
SciSpace
Search, PDF Q&A, and agentic literature review sit in one academic workspace, against a larger paper index than most rivals query.
- 280M+ paper corpus
- Agentic Deep Review search
- Cited answers over PDFs
- Writing aids (paraphrase, citations)
- Undisclosed underlying models
- Free tier limits depth
- Answer quality varies by field
