These are the 36 prompts worth saving for Mistral Le Chat. They target Mistral Medium 3.5, Mistral's unified flagship for 2026 that folds chat, reasoning, and coding into one 128B model with a 256K-token context window. In Le Chat, flipping on Work mode routes you to Medium 3.5 with extended reasoning — use it for anything multi-step.

Every prompt is written out in full and ready to copy. They follow the Role + Task + Context + Constraints + Output format shape, and they lean on Le Chat's real features: web search with citations, the Canvas workspace, the sandboxed code interpreter, the Agent Builder, and image generation via Flux. Swap anything in [BRACKETS] for your own details. New to the syntax? The Mistral prompt cheat sheet is a one-page reference, and the fill-in-the-blank templates turn these into reusable skeletons.

Work & productivity

Le Chat handles the daily grind — email, notes, planning, and documents. Turn on Work mode for the multi-step jobs and connect Gmail or Calendar so it can pull real context. For a deeper set, see the Mistral business prompts.

1. Inbox triage and draft replies

You are my executive assistant. Here are the emails from my inbox: [PASTE OR CONNECT GMAIL]. Triage them into: Reply now, Reply later, Delegate, and Ignore. For each "Reply now", draft a reply under 80 words in my voice (direct, warm, no filler). Output a table with columns Sender, Why it matters, Suggested action, and put the drafts below it.

Why it works: The triage buckets plus a word cap keep the drafts short and stop Le Chat from over-explaining.

2. Meeting notes to decisions and actions

Turn this meeting transcript into structured notes: [PASTE TRANSCRIPT]. Output three sections: Decisions made, Action items (as a table with Owner, Task, Due date), and Open questions. Do not invent details that are not in the transcript, and flag anything left unresolved. Keep it tight.

Best for: Turning a Zoom or Teams transcript into something the team can actually track.

3. Prioritized weekly plan

Here is everything on my plate this week: [PASTE LIST]. Act as a sharp chief of staff. Sort it by impact and urgency, name the three things that actually move the needle, and say what to delegate or drop. Lay it out as a simple day-by-day plan, and call out anything that looks like busywork.

Why it works: Asking Le Chat to name what to drop is where the prioritization actually happens.

4. Summarize an uploaded document

Read the attached document and give me: a 3-sentence executive summary, the 5 most important points as bullets, any numbers or dates that matter, and one section titled "What I should do about this." If the document contradicts itself or leaves something unclear, say so. Keep the whole thing under 300 words.

Best for: Contracts, reports, and long PDFs — Le Chat handles graphs, tables, and equations inside the file.

5. Project kickoff brief

You are a delivery lead. Turn this rough idea into a one-page project brief: [DESCRIBE PROJECT]. Cover: the goal in one sentence, scope (in and out), key milestones with rough dates, the main risks, and who needs to be involved. Use Work mode to think it through. Output clear sections, no filler, ready to paste into a doc.

Why it works: "Scope in and out" forces the boundaries that stop projects from ballooning.

6. Slide outline in Canvas

Open a Canvas and draft a [10]-slide deck outline for [PRESENTATION TOPIC] aimed at [AUDIENCE]. For each slide give a title, three bullet points, and a one-line speaker note. Keep one idea per slide and lead with the takeaway. End with a slide that states the single ask. Let me edit it in place.

Best for: A first draft you refine directly in Canvas instead of regenerating the whole thing.

Writing & content

Mistral writes cleanly and follows tone instructions well. Give it a role, the audience, and an exact format, and name the clichés to avoid. More in the Mistral writing prompts.

7. Blog post from an outline

You are a writer for [AUDIENCE]. Write a [1,200]-word blog post titled "[TITLE]" from this outline: [PASTE OUTLINE]. Keep the tone practical and direct, lead each section with the takeaway, use short paragraphs and concrete examples, and avoid clichés and filler. Output in clean Markdown with H2 sections and a two-line intro.

Best for: Turning a rough outline into a publishable draft that reads like a person wrote it.

8. LinkedIn post with a hook

Write a LinkedIn post for [MY ROLE] about [TOPIC / LESSON]. Open with a one-line hook that earns the scroll without clickbait, tell it as a short story or a concrete example, and end with a question that invites comments. Keep it under 150 words, use line breaks for readability, and no more than one emoji. Give me two hook options.

Why it works: A hook-plus-story structure and a hard word cap keep the post from turning into a listicle.

9. Rewrite for clarity and tone

Rewrite the text below to be clearer and more direct without losing meaning. Cut filler, fix weak verbs, and keep my key terms. Target a [confident but plain] tone at a [general professional] reading level. Return the rewrite first, then a short bullet list of the main changes you made. Text: [PASTE TEXT]

Best for: Tightening anything you have already drafted; the change list shows its work.

10. Cold outreach email

You are writing a cold outreach email from me ([MY ROLE] at [MY COMPANY]) to [PROSPECT ROLE] at [PROSPECT COMPANY]. Goal: [GOAL]. Keep it under 90 words, open with a specific reason I am reaching out to them (not a template), state one clear value point, and end with a low-friction ask. Give me three subject-line options.

Why it works: Naming a real reason to reach out is what separates this from spray-and-pray outreach.

11. Newsletter from raw notes

Turn these raw notes into a [500]-word newsletter issue for [AUDIENCE]: [PASTE NOTES]. Structure: a strong one-line opener, 3-4 short sections with subheads, and a closing line with one clear call to action. Keep my voice casual and specific, and suggest a subject line and preview text. Output in Markdown.

Best for: A weekly send where your notes stay the source of truth and Le Chat only handles structure.

12. Headline and subject-line variations

Generate 12 headline options for [PIECE / PRODUCT] aimed at [AUDIENCE]. Mix angles: benefit-led, curiosity, contrarian, number-led, and how-to. Keep each under 65 characters, avoid hype words, and label the angle of each. Then pick your top three and say why they would perform best.

Why it works: Labeling the angle of each option makes the batch testable instead of interchangeable.

Coding & Vibe

Mistral's coding stack — Codestral, Devstral 2, and the Vibe agents — is a real strength; Medium 3.5 posts 77.6% on SWE-Bench Verified. Always paste real code and state your language, versions, and the exact error. Full set in the Mistral coding prompts.

13. Debug with root cause

I am getting this error in [LANGUAGE / FRAMEWORK version]: [PASTE ERROR]. Here is the relevant code: [PASTE CODE]. Think it through step by step, find the root cause, give me the corrected code, and explain what was wrong in two sentences. If more than one cause is possible, rank them by likelihood.

Why it works: Asking for a ranked set of causes keeps Le Chat honest on subtle bugs instead of committing to a guess.

14. Explain unfamiliar code

Explain what this code does to a developer new to [LANGUAGE / LIBRARY]: [PASTE CODE]. Give a one-paragraph overview, then a block-by-block walkthrough of the tricky parts, and call out any bugs, edge cases, or performance concerns you notice. Keep it concrete.

Best for: Onboarding to an unfamiliar codebase or reviewing a teammate's work.

15. Write unit tests

Write thorough unit tests for this function using [TEST FRAMEWORK]: [PASTE FUNCTION]. Cover the happy path, edge cases, invalid inputs, and boundary conditions. Explain in one line what each test verifies, and note any behavior in the function that looks like a bug or is ambiguous enough to need a spec decision.

Why it works: Flagging ambiguous behavior surfaces spec gaps while Le Chat writes the coverage.

16. SQL from plain English

Write a [PostgreSQL] query for this request: [WHAT I WANT]. Here is the schema: [PASTE TABLES / COLUMNS]. Return the query, a one-line explanation of each join or filter, and a note on indexes that would keep it fast at scale. If my request is ambiguous, state the assumption you made.

Best for: A correct, performance-aware query without hand-writing joins.

17. Refactor for readability

Refactor this code for readability and maintainability without changing behavior: [PASTE CODE]. Improve naming, reduce nesting, and extract logic where it helps. Return the refactored version, then a short bullet list of what you changed and why. Keep it idiomatic for [LANGUAGE] and do not add dependencies.

Why it works: "Without changing behavior" and "no new dependencies" keep the refactor safe to merge.

18. Scope a Vibe agent task

I want to hand this off to a Vibe cloud agent. Write a precise task spec it can run end to end in an isolated sandbox: [DESCRIBE THE TASK, e.g. fix the failing tests in module X]. Include the exact acceptance criteria, the files or areas it may touch, what it must NOT change, and how it should report back. Keep it unambiguous.

Best for: Routine fixes you delegate to an async Vibe agent with GitHub access. A tight spec is what makes the handoff work.

Research & web search

Le Chat has web search with citations built in. Ask for links by name and demand dates so you can verify every claim. Turn on Work mode when the research is multi-step. More in the business pack.

19. Cited web briefing

Search the web and give me a briefing on [TOPIC] as of this month. Cover: the current state, the three biggest developments in the last six months, the key players, and the open questions. Cite every claim with a link, prefer primary and recent sources, and note the publication date next to each fact. Output a bulleted brief under 400 words, then a one-line bottom line.

Why it works: "Note the publication date" exposes stale sources and keeps the briefing genuinely current.

20. Compare products with sources

Search the web and compare [PRODUCT A] and [PRODUCT B] for a [USE CASE] buyer. Build a table: price, key features, real user complaints, and best-fit user. Pull from current reviews and forums, cite every source with a link and date, and end with a clear recommendation for someone who cares most about [PRIORITY].

Best for: A buying decision grounded in current reviews, not last year's marketing copy.

21. Fact-check a claim

Fact-check this claim using web search: "[CLAIM]". Find the original source, what the primary evidence actually says, and how credible outlets have covered it. Rate it True / Misleading / False / Unproven with a short reason. Cite every source with a link and date, and separate what is confirmed from what is still uncertain.

Why it works: Forcing a rating plus a "still uncertain" bucket stops Le Chat from smoothing over a genuinely open question.

22. Market landscape map

Use Work mode and web search to map the current landscape of [MARKET / INDUSTRY]. Cover the main players and their positioning, recent funding or M&A, pricing norms, and where the market is heading. Cite every source with a link and date, and end with two gaps or openings a new entrant could target.

Best for: A fast, sourced lay of the land before a strategy or investment call.

23. Summarize a web page

Read this URL and summarize it for me: [PASTE URL]. Give a 3-sentence overview, the key points as bullets, any data or claims worth double-checking, and one line on what the author wants me to do or believe. If the page is thin or promotional, say so. Keep it under 200 words.

Why it works: Asking what the author "wants me to believe" surfaces spin that a plain summary hides.

24. Evidence review

Use Work mode and web search to review the current evidence on [RESEARCH QUESTION] published in the last two years. Summarize what the strongest sources agree on, where they disagree, and what remains unsettled. Cite each source with a link and date, weight studies over opinion pieces, and end with a short "confidence and gaps" note.

Best for: A grounded evidence synthesis rather than a confident-sounding guess. Cross-reference with Claude or Gemini for a second read.

Data & documents

Le Chat's sandboxed Python code interpreter runs real analysis, and it reads PDFs, spreadsheets, and scanned images directly. Upload the file and tell it exactly what to compute. See the structured output guide for extraction.

25. Analyze a CSV

Here is a CSV: [UPLOAD FILE]. Using the code interpreter, load it, describe the columns and row count, and answer these questions: [YOUR QUESTIONS]. Show the key numbers, flag any data-quality issues (missing values, outliers, duplicates), and end with the three findings that matter most for [DECISION]. Do not speculate beyond the data.

Why it works: Running actual Python beats an eyeballed guess, and the data-quality check catches the usual traps.

26. Spreadsheet formula and model

I need a [Google Sheets] formula/model to [GOAL]. My data is laid out like this: [DESCRIBE COLUMNS]. Give me the formula, explain what each part does, and note common ways it could break (blank cells, text vs numbers). If a small helper column would make it cleaner, suggest it.

Best for: An explained formula plus the gotchas, so you can maintain the sheet yourself.

27. Extract structured JSON

Extract structured data from the text below into valid JSON only — no prose. Use exactly this schema: {"company": string, "contact": {"name": string, "email": string}, "items": [{"sku": string, "qty": number, "price": number}], "total": number}. If a field is missing, use null. Do not invent values. Text: [PASTE TEXT]

Why it works: Mistral is strong at structured output; naming exact keys and types and forbidding prose gives you parseable JSON on the first try.

28. Chart from data

Using the code interpreter, make a clean chart from this data: [PASTE OR UPLOAD]. Chart type: [bar / line / scatter]. Put [X] on the x-axis and [Y] on the y-axis, label the axes and title clearly, and use a colorblind-friendly palette. Then tell me in two sentences what the chart shows and one thing that stands out.

Best for: A presentable chart plus the one-line insight to caption it with.

29. Summarize a long PDF report

Read the attached [report / whitepaper] and produce: a one-paragraph executive summary, the key findings as bullets with the page numbers, any figures or tables worth quoting, and a "so what for [MY ROLE]" section. Note anything the report claims without evidence. Keep the whole thing to one page.

Why it works: Page numbers make the summary auditable, and the 256K context means Le Chat can hold the whole report at once.

30. Turn a scanned doc into a table

Here is a scanned [invoice / receipt / form]: [UPLOAD IMAGE OR PDF]. Read the text (OCR), then extract the fields into a table with columns [FIELD 1], [FIELD 2], [FIELD 3]. Preserve exact numbers and dates, and mark any field you could not read clearly as "unclear" rather than guessing. Output the table only.

Best for: Digitizing paperwork; the "mark unclear, do not guess" rule keeps the data trustworthy.

Multilingual, business & features

Mistral's multilingual and EU-business strengths are a real edge, and Le Chat's Agent Builder and Flux image generation round out the toolkit. See the translation and multilingual prompts for more.

31. Translate and localize

Translate the text below from [SOURCE LANGUAGE] into [TARGET LANGUAGE] for a [AUDIENCE / REGION]. Do not translate word-for-word — localize idioms, units, currency, and tone so it reads as if written by a native speaker. Keep the meaning and any names or product terms exact. Return the translation, then a short note on any choice you had to make. Text: [PASTE TEXT]

Why it works: "Localize, do not translate word-for-word" is what makes Mistral's multilingual output read natively instead of stiff.

32. Draft in a European business register

Write a [formal business email] in [French / German / Spanish / Italian] from [MY ROLE] to [RECIPIENT] about [PURPOSE]. Match the professional register and courtesy conventions native to that language and country, not a translated English tone. Keep it under [120] words, end with one clear ask, and add an English gloss below so I can check it.

Best for: EU business communication where a translated-from-English tone would land wrong.

33. Build a no-code agent

Help me build a reusable agent in Le Chat's Agent Builder that [WHAT IT DOES, e.g. summarizes new support tickets and drafts a reply]. Write: the agent's system instructions, the inputs it should expect, the tools it needs (web search, code, connectors), the output format, and 3 test inputs with the expected output. Keep the instructions specific enough that it behaves the same every run.

Why it works: Specifying tools, output format, and test cases up front is what makes a no-code agent reliable instead of flaky.

34. Generate an image with Flux

Generate an image: [SUBJECT with 2-3 defining details], in [ENVIRONMENT], lit by [LIGHTING], in a [SINGLE STYLE, e.g. editorial product photography]. Shot [CAMERA / LENS or ANGLE], [MOOD]. Aspect ratio [16:9 / 1:1 / 9:16]. Keep one coherent style and skip quality-adjective spam like "8k ultra masterpiece."

Best for: Quick visuals inside Le Chat; image generation is powered by Black Forest Labs' Flux.

35. Decision brief with a recommendation

You are a pragmatic strategy advisor for a [COMPANY TYPE]. We are deciding whether to [DECISION]. Context: [KEY FACTS AND CONSTRAINTS]. Use Work mode to reason it through, then lay out the options, the main trade-offs, the biggest risk, and what you would do and why. Be blunt about weaknesses. Output a one-page brief: recommendation, rationale, risks, next step.

Why it works: The "be blunt" line and a fixed brief structure give you a decision doc, not a hedge.

36. Structured output for an app

You are a classification function. For each input below, return valid JSON only matching this schema: {"category": one of ["billing","technical","account","other"], "priority": one of ["low","medium","high"], "summary": string (max 15 words)}. No prose, no markdown fences. If the input is empty, return {"category":"other","priority":"low","summary":"empty input"}. Inputs: [PASTE ITEMS]

Best for: Wiring Mistral into a pipeline; its native function calling and structured-output discipline make the JSON dependable.

Frequently Asked Questions

Which Mistral model are these prompts built for?

They target Mistral Medium 3.5, Mistral's unified flagship as of 2026, which folds chat, reasoning, and coding into one 128B model with a 256K-token context window. In Le Chat, switching to Work mode routes you to Medium 3.5 with extended reasoning. The prompts also run on Mistral Large and the open Small models.

What is the Mistral prompt formula?

Role + Task + Context + Constraints + Output format. Lead with a specific role like "You are a senior data analyst", state the one task, give the context, set the limits, and name the exact output shape. Mistral rewards concise prompts where every sentence earns its place.

How do I get web-sourced answers in Le Chat?

Le Chat has built-in web search with citations on the free tier. Ask it to "search the web and cite every source with a link", or paste a URL and tell it to summarize the page. For heavier multi-step research, switch to Work mode so it plans before it answers.

Can Le Chat write and run code?

Yes. Le Chat has a sandboxed Python code interpreter for data analysis and charts, plus the Codestral and Devstral models behind its coding features, and Vibe cloud agents that can handle routine fixes in isolated sandboxes with GitHub and Slack integrations.

Is Mistral good for non-English work?

It is one of Mistral's core strengths. The models are strong across French, German, Spanish, Italian, and many other languages, which makes Le Chat a good fit for translation, localization, and EU business communication. Name the target language and register in your prompt.

What is Canvas in Le Chat?

Canvas is a free-form workspace where Le Chat drafts documents, code, and design mockups you can edit in place without regenerating the whole answer. It supports version tracking and live previews, which makes it ideal for iterating on a doc or a landing page.

How do the [BRACKET] placeholders work?

Anything in square brackets is a swap-in. Replace [TOPIC], [AUDIENCE], or [PASTE TEXT] with your own details before sending, and delete any bracket you do not need. The rest of each prompt is written to be copy-paste ready.
