CaryHealth Clair vs Rejoy Health (2026)
Two small clinical AI companies with very different scope. Clair, from CaryHealth, is a drug and therapeutics reference built on named public sources: FDA package inserts, the NIH trials database, a National Library of Medicine interaction database and clinical guidelines. Every answer links to its references, and an API lets other products embed it. Rejoy Health sells a whole care team suite: a clinical question assistant, a scribe, a coder, a receptionist that books appointments, a live interpreter and decision support. The scribe now leads its home page, and it publishes a full price ladder, from a free plan to $199 per clinic per month. Choose Clair for a narrow reference with named sources. Choose Rejoy for breadth at a published price, and check which plan carries a business associate agreement before trusting it with patient data.
- A bounded corpus of named public drug, trial and guideline sources, with every answer linked to its references.
- Published API documentation for embedding the reference in another product.
- A $9.99 professional subscription after a free trial.

- Published prices: a free plan with 25 questions a day, Pro at $63 per clinician per month and Practice at $199 per clinic per month, billed annually.
