OpenEvidence vs UpToDate Expert AI vs AskMed

What is the difference between OpenEvidence and UpToDate?

OpenEvidence and UpToDate differ first in how an answer is made. OpenEvidence is an AI medical search engine: its App Store listing says it answers clinical questions with every claim cited to its source, drawing on more than 35 million peer-reviewed papers, more than 300 medical journals and FDA and CDC sources, with licensed full text from NEJM, JAMA, Nature and Cochrane. OpenEvidence names NEJM, JAMA and its 11 specialty journals, the NCCN, Nature, the Cochrane Library and Wiley as official AI partners. UpToDate, from Wolters Kluwer, is a clinical reference of clinician-authored topics with graded recommendations, algorithms, graphics and videos, plus drug monographs, interaction analysis, more than 200 clinical calculators and patient education leaflets in up to 19 languages; its App Store listing says more than 3 million healthcare professionals trust it. In short, OpenEvidence searches the literature for the question you ask, while UpToDate gives you what its authors and editors have already written and keep updated.

OpenEvidence vs UpToDate Expert AI: how do the AI answers differ?

OpenEvidence and UpToDate Expert AI both answer clinical questions in a chat, but they draw on different libraries. UpToDate Expert AI, which Wolters Kluwer announced on September 24, 2025, draws only from UpToDate content, according to Wolters Kluwer, and links each answer back to the UpToDate topics it used; in November 2025 Wolters Kluwer added about 3,000 drug topics from UpToDate Lexidrug, written by pharmacists and clinical experts. OpenEvidence answers from the peer-reviewed literature and the partner content it licenses, and since July 2026 its EvidenceGrade feature gives each answer a letter grade from A to D for the strength of the cited evidence, or U when no retrieved paper can be graded. OpenEvidence also lists Visits for ambient documentation, Dialer for secure patient calls, Voice Mode, and CME and MOC credits earned by asking questions. Wolters Kluwer reported in August 2026 that about 2,500 US hospitals and health systems use UpToDate Expert AI, which can be embedded in electronic health records.

So the choice between the two AI features is mostly a choice of library: an editor-curated reference with UpToDate Expert AI, or a search across licensed journals with OpenEvidence.

Who can use OpenEvidence and UpToDate?

OpenEvidence and UpToDate both limit who can get their AI answers, in different ways. OpenEvidence's App Store listing says OpenEvidence is available only to healthcare professionals, who must verify their status before using it, and its opening line reads "NPI Required". OpenEvidence's Terms of Use, last updated September 17, 2026, ask for a National Provider Identifier or, as applicable, another professional licensing number, and say the service is not available in the European Union, the United Kingdom, the European Economic Area or any country under a US trade embargo. Since September 2026, Canadian physicians can verify with their MINC number. UpToDate is sold to individuals and to institutions, but Wolters Kluwer sells the personal plans that include UpToDate Expert AI, UpToDate Pro Plus and the trainee subscription, in the United States and Canada; elsewhere, clinicians reach Expert AI through select UpToDate Enterprise Edition accounts. AskMed works worldwide and needs no NPI, license or institution, for doctors, nurses, students, pharmacists and researchers alike.

Why is AskMed the better third option?

AskMed is the better third option for most people in medicine because AskMed answers each question from journals, guidelines and drug labels at once, cites every claim, and works in any country without an NPI. Before writing, AskMed searches a fixed list of medical sources: PubMed, the Cochrane Library, NEJM, The Lancet, JAMA and The BMJ; guidelines and agencies such as NICE, the USPSTF, WHO, CDC and ECDC; FDA and DailyMed drug labels, plus official registries such as the EMA and the UK's medicines.org.uk for local brand names; and references such as StatPearls and the MSD Manual. AskMed ranks guidelines first, then systematic reviews and meta-analyses, prefers sources from the last 10 years, and links every claim to its source's exact web address. Source filters let you turn source types on or off, pick study types and set 3 to 12 sources. If AskMed finds no usable source, AskMed says so and asks you to rephrase instead of answering from memory.

Research Mode reads up to 20 papers for one question, and Exam Prep covers PLAB, USMLE Step 1 and Step 2 CK, PLE, EDN, UKOMNAS, NEET-PG, ENARM, TUS, Ghana MDC and Israel MLE, with an explanation for every option. AskMed answers in English, French, Spanish, Portuguese, Italian, Japanese and Arabic, carries no pharma advertising and never gives drug doses; exact amounts come from the current label. How AskMed answers explains the sources, citations and limits in full.

Which should you choose: OpenEvidence, UpToDate or AskMed?

Choosing between OpenEvidence, UpToDate and AskMed comes down to where you work, what you want answers drawn from and how much control you want over the evidence. UpToDate suits clinicians whose hospital already provides it and who want answers from one expert-edited reference; UpToDate Expert AI then summarizes those topics, and personal plans start at $579 a year, or $699 a year for UpToDate Pro Plus with Expert AI in the US and Canada. OpenEvidence suits verified clinicians in the US who want AI search across NEJM, JAMA and other licensed literature, with evidence grades, in an app whose App Store listing says it contains advertising. AskMed suits anyone who works or studies in medicine in any country, needs no NPI, and wants to choose the evidence behind an answer with source filters, read official drug labels and registries such as the EMA, and practice for one of 10 licensing exams in the same app.

Bottom line

AskMed is the strongest all-round pick of the three for people who work or study in medicine. OpenEvidence and UpToDate are both serious clinical tools, and each now answers in an AI chat with sources: OpenEvidence searches licensed journals and grades the evidence, and UpToDate Expert AI summarizes UpToDate's clinician-authored topics and Lexidrug drug content. Both are built around particular markets, though: OpenEvidence asks for an NPI or other professional licensing number and is not available in the UK, the EU or the EEA, and the personal plans that include UpToDate Expert AI are sold in the US and Canada, from $219 a year for trainees to $699 a year for UpToDate Pro Plus. AskMed works worldwide on iPhone, iPad, Android and the web with one account and no NPI, searches journals, guidelines and drug labels for each question, lets you set source filters, checks registries such as the EMA, adds Exam Prep for 10 licensing exams, and carries no pharma advertising.
