AskMed vs Le Chat (Mistral)

What is Le Chat?

Le Chat is the AI assistant made by Mistral AI, a French AI company, and Mistral has since renamed Le Chat to Vibe. Mistral's help center says "Le Chat is now Vibe, Mistral's unified agent for professional productivity and coding tasks", with three modes: Vibe Work, the productivity mode people used in Le Chat; Vibe Code, a coding mode for developers; and Vibe Chat, the turn-based conversation Le Chat was known for. The web address chat.mistral.ai still works, and accounts and conversations carried over. On the App Store and Google Play the app is now called "Vibe by Mistral (ex-Le Chat)" and sits in the Productivity category. The store listings describe catching up across email, chat and calendar, running deep research across the web, internal docs and connected tools, analysing spreadsheets and drafting reports. Mistral's pages don't present Le Chat as a medical tool, and none of them names a list of medical sources.

Mistral's Usage Policy, under "Professional advice", says its products must not be used "to provide professional advice without proper qualification", and gives "offering medical diagnoses, treatment suggestions, or any form of health-related guidance" as an example. Mistral's help center also says Vibe "can occasionally respond with incorrect answers or facts" and recommends checking whether its responses are accurate.

How do AskMed and Le Chat answer a medical question differently?

AskMed and Le Chat differ most in where an answer comes from. AskMed searches a fixed list of medical sources before any answer is written: journals such as 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; and references such as StatPearls. AskMed doesn't search the open web, forums or social media. AskMed ranks guidelines first, then systematic reviews and meta-analyses, prefers sources from the last 10 years, and links each claim to its source's exact web address. Le Chat, now Vibe, gathers context "from your prompt, attached files, connected tools, or the web", in the words of Mistral's documentation, and its deep research compiles "sourced analysis" from the web, internal docs and connected tools. Mistral doesn't state a medical source list, a ranking of evidence or a citation after every claim. For a clinical question, that difference decides how much checking an answer needs.

When AskMed finds no usable medical source, AskMed gives a fixed reply that says so and asks you to rephrase, instead of answering from memory. Source filters let you turn journals, guidelines, drug labels or references on or off, choose study types from systematic reviews to clinical trials, and set 3 to 12 sources per answer. How AskMed answers explains the full source list and its limits.

Where do drug facts come from?

AskMed answers drug questions from official drug labels, the prescribing information a regulator approved, while Mistral's pages name no drug label source for Le Chat. AskMed reads FDA labels and DailyMed, and for brand names sold outside the US it also checks official drug registries, such as the European Medicines Agency and the UK's medicines.org.uk, so a local brand name leads to the right label. The label is the primary document for a medicine's indications, contraindications, boxed warnings, interactions and adverse reactions. Each drug claim in AskMed links to the label's exact web address, so a pharmacist checking an interaction or a nurse checking a side effect can open the label and confirm the wording. AskMed never gives drug doses, dose calculations or titration schedules. A drug answer still covers what the drug is used for, how it works, first-line and alternative options, how dosing is adjusted for kidney or liver function, monitoring and side effects. Exact amounts come from the current label.

Exam prep built in

AskMed includes Exam Prep for 10 licensing exams, while Mistral's pages state no question bank for Le Chat. AskMed's question banks cover PLAB, USMLE Step 1 and Step 2 CK, PLE, EDN, UKOMNAS, NEET-PG, ENARM, TUS, Ghana MDC and Israel MLE. Each bank is written in the language of its exam, so a candidate for a non-English exam practices in the language of the real paper. Every question comes with an explanation for every option, not only the right one, and a timed mock of 40 questions in 60 minutes lets you practice under exam conditions. When a question raises something you don't know, you can ask AskMed in the same app and get an answer cited to journals, guidelines and drug labels, then go back to the bank. For a medical student, a resident or an international medical graduate, AskMed keeps exam practice and cited clinical answers in one account on iPhone, iPad, Android and the web, in any country.

The best AI apps for USMLE guide compares AskMed with other study tools for Step 1 and Step 2 CK, and the PLAB 1 guide does the same for the UK exam.

When should you use each?

Use AskMed for medical questions and Le Chat for general work, because each tool is built for that job. AskMed is the pick when an answer will inform a clinical decision, a care plan, a drug check or an exam: a doctor confirming a guideline, a nurse checking a monitoring plan, a pharmacist reviewing an interaction, a student revising for finals or a researcher scoping a question. In each case AskMed searches journals, guidelines and drug labels first and links every claim. Le Chat, now Vibe, is built for professional productivity and coding, and Mistral's pages name tasks such as catching up across email, chat and calendar, analysing spreadsheets, drafting reports and writing code in the terminal or VS Code. A clinician can use Le Chat to draft a rota email and use AskMed for the evidence behind the clinical content. Mistral's Usage Policy lists health-related guidance among the professional advice its products must not be used to provide without proper qualification.

How to check an AI medical answer

Checking an AI medical answer takes five steps, whichever tool wrote the answer, AskMed and Le Chat included. First, open the source behind the sentence you plan to act on and read what the source itself says; an answer with a citation after every claim lets you check one sentence against one page. Second, check the kind of source: a current guideline or a systematic review carries more weight than a news story or a blog. Third, check the year, because guidance changes and an older recommendation may have been replaced. Fourth, check drug facts against the official label, such as an FDA label or the EMA's product information, since drug websites summarize the label and can lag behind an update. Fifth, check local practice, because guidelines and drug approvals differ between countries. Mistral's help center itself says Vibe "can occasionally respond with incorrect answers or facts". AskMed makes these checks quicker by labelling each source as a Guideline, Research, Drug label or Reference.

1. Open the source. Read the cited page for the sentence you will act on, not just the answer around it.
2. Weigh the source. Guidelines and systematic reviews come before single studies, and studies before news or blogs.
3. Check the year. Make sure the guideline is the current version, not one that has been replaced.
4. Check the label. Confirm drug facts in the official prescribing information for your country.
5. Apply local practice. Approvals, first-line choices and thresholds differ between countries and settings.

Bottom line

For medical questions, AskMed is the stronger choice over Le Chat. Le Chat, which Mistral has renamed Vibe, is a general assistant for professional productivity and coding, listed under Productivity on the App Store and Google Play, and Mistral's pages name no medical source list. AskMed is built for everyone in medicine, from doctors, residents and medical students to nurses, pharmacists and researchers. AskMed searches a fixed list of journals, guidelines and drug labels before answering, links every claim to its source, and says so when no source supports an answer instead of answering from memory. Source filters let you choose source types, study types and 3 to 12 sources. AskMed reads FDA labels and official registries such as the EMA for local brand names, never gives drug doses, and includes Exam Prep for 10 licensing exams.
