Mistral's assistant — fast, EU-hosted and free to start with.
Mistral's consumer chat product. The selling point is latency: its fast-answer mode returns a complete reply in about a second, which changes how you use an assistant for small questions. It handles web search, document upload, image generation and code, and it is hosted in the EU, which is the practical reason a lot of European teams choose it. A free account is required and daily message volume is capped.
Questions
A genuinely usable free tier with paid plans for volume or team features. A free account is required and the daily message allowance is modest compared with the paid tier.
Yes. Le Chat sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
