Doximity Ask vs OpenEvidence (2026)
Doximity Ask, formerly Doximity GPT, is the AI assistant inside Doximity's professional network, whose members include more than 85 percent of US doctors, and it is free to verified US physicians, nurse practitioners, physician assistants and students. It answers clinical questions with inline citations and full text from more than 2,000 journals, draws drug answers from monographs grounded in FDA labeling, reads uploaded labs and notes, and drafts prior authorization requests, appeal letters and letters of medical necessity that can go out by Doximity's fax. Its reference layer came from Pathway, acquired in 2025, and in October 2026 Doximity agreed with Wolters Kluwer to show UpToDate content beside Ask's answers for health systems that license both. OpenEvidence is AI medical search used at the point of care, free to verified US and Canadian clinicians and funded by pharmaceutical and device advertising. It grounds answers in more than 300 journals under AI partnerships with NEJM, JAMA, Nature, Cochrane and NCCN, and its EvidenceGrade label rates the evidence behind each answer. Health systems including Mount Sinai, Cedars-Sinai and UTMB run it inside the record, and Visits records encounters and drafts notes, after visit summaries and billing codes. The company reports more than 200 million clinical consultations to date. Both are free and both are paid for by others, OpenEvidence through advertising inside the product and Doximity mainly through pharmaceutical marketing and hiring sales across its network. OpenEvidence has peer reviewed studies of its citations, guideline answers and triage, offers a SOC 2 Type II report through its trust center, and sits inside the chart at named health systems. Doximity has a public business associate agreement, a SOC 3 report and a panel of more than 12,000 physicians reviewing answers, but publishes no evaluation of Ask, no record integration and no model provider. A clinician who wants answers and payer paperwork in one place has a reason to open Doximity Ask, and a health system that wants studied, cited answers in the chart has a reason to open OpenEvidence.

- Peer reviewed studies found no fabricated reference across 4,979 citations and 100 percent citation accuracy across 999 spine guideline citations.
- Mount Sinai, Cedars-Sinai and UTMB run it inside the electronic health record.
- Visits records the encounter and drafts the note, after visit summary and billing codes.

Each vendor in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached.
Doximity Ask is the free clinical AI assistant inside Doximity's network for verified US physicians, nurse practitioners, physician assistants and students. It answers clinical and drug questions with inline citations, reads uploaded documents, and drafts prior authorizations, appeal letters and letters of medical necessity that can be faxed from Doximity. Doximity reports deployment at more than 165 health systems, publishes its member business associate agreement and a SOC 3 report, and is adding UpToDate content for health systems that license both. The main caveat is that it publishes no evaluation of Ask's answers and names no model provider, and its agreement lets Doximity commercialize deidentified data.

OpenEvidence is a free, advertising funded medical search product for verified US and Canadian clinicians, answering from more than 300 journals under publisher partnerships with a strength of evidence label on each answer. Independent peer reviewed studies have tested its citations, guideline concordance and triage, and health systems such as Mount Sinai and UTMB run it in the record. It now also records encounters and drafts notes through Visits, and offers a SOC 2 Type II report through its trust center. The main caveat is that it names no foundation model supplier, publishes no retention schedule and left the EU and UK in April 2026.

Questions buyers ask
How does Doximity Ask compare to OpenEvidence?
Doximity Ask and OpenEvidence are both free AI clinical search tools for verified clinicians, reached through different front doors. Doximity Ask sits inside Doximity's professional network and pairs cited answers with drafted prior authorizations and appeal letters. OpenEvidence is a standalone search product with publisher partnerships, an evidence strength label and deployments inside the record. OpenEvidence has peer reviewed studies of its answers, and Doximity publishes none for Ask. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified November 3, 2026. No vendor pays for placement.
Are Doximity Ask and OpenEvidence really free?
Yes, for verified individual clinicians. Doximity Ask is free to verified US physicians, nurse practitioners, physician assistants and students, and Doximity earns mainly from pharmaceutical manufacturers and health systems buying marketing, hiring and workflow products. OpenEvidence is free to verified US and Canadian clinicians and shows pharmaceutical and device advertising inside the product. Neither Doximity nor OpenEvidence publishes enterprise or health system pricing. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified November 3, 2026. No vendor pays for placement.
How accurate are Doximity Ask and OpenEvidence?
OpenEvidence has independent peer reviewed studies, including no fabricated reference across 4,979 citations, 100 percent citation accuracy on 999 spine guideline citations and 71.3 percent triage accuracy, and it scored below general purpose models in a June 2026 Nature Medicine benchmark. Doximity publishes no evaluation of Ask, and its panel of more than 12,000 physicians reviews answers without published results.
Doximity says Ask ranked top in the NOHARM preprint, which names no tools in its main text and found no significant differences among the clinical tools tested. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified November 3, 2026. No vendor pays for placement.
Can Doximity Ask and OpenEvidence be used with patient information?
Both accept it under a business associate agreement. Doximity publishes its member agreement, entered at registration, though no list confirms Ask among the covered tools, and the agreement lets Doximity deidentify and commercialize data. OpenEvidence states business associate status on its security page and says it does not train AI models on protected health information. Neither Doximity nor OpenEvidence publishes how long prompts or uploads are kept. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified November 3, 2026. No vendor pays for placement.
Do Doximity Ask and OpenEvidence work inside the EHR?
OpenEvidence does at named health systems, including Mount Sinai across seven hospitals, Cedars-Sinai and UTMB, which has run it in the record since March 2026. Doximity Ask has no published record integration; clinicians upload documents and send drafted letters by Doximity's fax, and notes are copied into the chart. Doximity's October 2026 UpToDate partnership adds reference content inside Ask rather than a connection to the record. From the AI Health Index, drawn from each vendor's own published materials and the regulatory record, verified November 3, 2026. No vendor pays for placement.

Other published head to head assessments involving these vendors or their closest peers.
Neither vendor publishes how long prompts are kept, an enterprise price, or a measured error rate of its own. Doximity does not name the model behind Ask, publish results from PeerCheck, confirm that Ask is a covered tool under its business associate agreement, or say what the UpToDate content will cost. Ask Doximity for those. OpenEvidence does not name a foundation model supplier or say whether an enterprise agreement removes advertising. Ask OpenEvidence for those and for how its advertising partners may use activity data.
