Clinical AI for US practice
Clinical answers you can verify.
Ask one question. Primary AI searches current guidelines, medical literature, and FDA labels — with Canadian guidance when it differs. Every citation links back to the evidence.
From question to verified answer
- Ask. Start with one clinical question.
- Understand. Primary AI identifies the decision and clinical context.
- Search. It retrieves guidelines, literature, and FDA labels.
- Answer. It writes a direct clinical response.
- Verify. It checks each citation before display.
Clinical AI search for US physicians
Primary AI is a clinical AI search and answer tool for licensed clinicians in the United States. It retrieves current medical evidence, surfaces US guidance first, and shows Canadian guidance when practice differs — with a direct source link on every cited claim.
Primary AI searches publicly accessible medical content, public guidance, trial registries, drug labels, and public health material. Each citation opens the public source page when one is available.
Questions clinicians ask
How does Primary AI handle patient information?
Clinical questions must be de-identified by default. Authorized clinicians can use patient information in Primary AI Assistant for care. Approved Canadian Business API customers can use a separate PHI path under written terms. Assistant transcripts and notes are private to the user and deleted after 30 days. Clinicians must obtain consent when required and meet applicable privacy requirements.
How are citations verified?
Every reference is checked against a live PubMed and DOI lookup so the paper actually exists before it is shown to you. A hard no-fabrication guardrail instructs the model to refuse rather than invent a citation, and recommendations are graded by evidence type (RCT, meta-analysis, guideline, or expert consensus).
Is Primary AI free for clinicians?
Yes. Primary AI is free for licensed clinicians — no credit card and no patient data required. It is intended solely for credentialed healthcare professionals acting in their professional capacity.
Which guidelines and sources are covered?
Primary AI searches publicly accessible medical content, public guidance, trial registries, drug labels, and public health material. Each answer links to the cited public page when one is available. When guidance differs between locations, Primary AI identifies the difference.
How does Primary AI compare to OpenEvidence?
OpenEvidence made AI clinical search mainstream and is widely adopted among US physicians. Primary AI is built for clinicians who want direct links to cited public pages, citations verified against live lookups, location-aware guidance, and local antibiotic resistance patterns. See our detailed comparison at /vs/openevidence.
Does Primary AI store my data or train AI models on it?
We store account information, saved conversations, query logs, and usage records as described in our Privacy Policy. Assistant records expire after 30 days and are removed by an hourly deletion job. AI providers process inputs under the terms and settings for the service used. See the Privacy Policy for retention, provider processing, advertising uses, and your choices.
