First Steps for a Small Business

Updated November 2, 2026 — Le Chat is now Vibe. As of May 28, 2026, Le Chat has been rebranded as Vibe (still at chat.mistral.ai): a single agent for work and code that retains your conversations, settings, and subscriptions. The legacy Le Chat experience remains accessible in Chat mode. In Work mode, agents have become skills (invoked with @), memories serve as the knowledge base, and deep search is now the Deep Research skill. The plans are now called Mistral Free, Pro, Team, and Enterprise. This lesson uses the name Vibe; note that some menus described here may have changed names or locations.

Create your Mistral account in three minutes

Enough theory: by the end of this lesson, you will have a working account and your first genuinely useful interaction with Vibe.

Open your browser and go to chat.mistral.ai, the address for Mistral’s conversational interface. Click “Sign up.” You have three options: a professional email address, a Google account if your company runs on Google Workspace, or a Microsoft account if you use Microsoft 365. Stick with your professional email: this lets you switch frictionlessly to the Business plan if your team grows. When choosing a plan, stay on the free tier. Upgrading to Pro takes two clicks from settings, and there is no reason to pay until you have used the tool for several days.

Your first useful conversation

When discovering a conversational assistant, the temptation is to ask for a joke. Resist it: your first impression shapes how you will use the tool going forward. Start with a real problem on your desk, such as a difficult email to write: “I need to reply to an unhappy customer complaining about a 5-day delivery delay. The delay was caused by our supplier. I want to apologize, explain the situation without blaming the supplier, and offer a 10% discount. My usual tone is professional but warm. Draft this email.” Read the response, then compare the time saved against how long you would have spent wrestling with the same paragraph.

Your second move should involve documents. If a multi-page contract or report is sitting in your inbox, click the attachment icon, upload the PDF, and ask: “Summarize this document in 5 key points. Identify the main obligations for my company and the deadlines to meet.” The third use case to test on day one is meeting preparation: “I have a meeting tomorrow with a prospect in the logistics sector. My company sells inventory management solutions. Prepare 5 relevant questions to ask and 3 sales arguments tailored to the logistics industry.”

Configure Vibe for your business

Vibe settings include a Custom Instructions section: permanent text applied to all your conversations so you do not have to repeat it. This is the setting that transforms a generic assistant into one that knows your context, yet it is the feature most users never discover.

Here is a template to copy, replacing the brackets: “I am the owner of a French SME with [X] employees in the [your sector] sector. My company is called [name]. We sell [products/services] primarily to [customer type]. When you draft text for me, use a professional but accessible tone. Always address clients formally. Use the metric system and French conventions (dates, addresses, etc.).”

Adopt one good habit from day one: one conversation per topic. Vibe keeps your history in the sidebar, and a thread like “Email to Client Dupont” will remain usable in six months, unlike a catch-all mixing a follow-up, a supplier search, and a newsletter draft. The tighter the context, the more relevant the answers.

Five use cases that pay off on day one

Writing tops the list: follow-ups, responses to complaints, sales messages, and administrative letters are produced in seconds, in the tone you specify. Translation comes next, invaluable if you deal with foreign clients or suppliers, because Vibe grasps business context where a standard translator stays literal.

The third use case is meeting minutes: type your raw notes right after a meeting and ask for a structured document, with decisions on one side and action items on the other. The fourth is information research, which replaces half an hour of browsing for a question on industry regulations or a supplier comparison. The fifth is content creation—LinkedIn posts, product descriptions, newsletters, presentations—where the tool delivers a first draft ready for refinement.

Four startup pitfalls

Do not paste sensitive personal data into a conversation, such as social security numbers or your clients’ bank details, even with a GDPR-compliant tool: transmit only what is strictly necessary for the task. Always review responses, prioritizing figures and dates. Do not start with automation: master the conversational mode first; connections to your tools will come later. Finally, do not draw conclusions from a single disappointing response—rephrase, clarify, add context. It is a dialogue, not a vending machine.
