Pros & Cons
OpenEvidence
- Genuinely free for verified US healthcare professionals, funded entirely by advertising
- Massive real-world adoption — approximately 20 million clinical consultations/month as of January 2026
- Substantial recent funding ($250M Series D, $12B valuation) suggests continued platform investment
- Access requires a US NPI number, excluding non-US healthcare professionals
- Withdrew from the EU and UK entirely in April 2026, cutting off previous international access
- Ad-supported model means pharmaceutical advertising is shown during use
Andi Search
- Faster to get a direct answer than scanning a traditional results page
- Supports conversational follow-up questions
- Provides citations for verifying synthesized answers
- Answer reliability depends entirely on the quality and transparency of cited sources
- Faces much better-funded competition from newer answer-engine products
- Best treated as a starting point rather than a final source for anything important
