- European company subject to GDPR
- Free plan covers most everyday needs
- Trails top rivals on complex reasoning and coding
- Chats train models by default unless you opt out
- No desktop app for Mac or Windows
Vibe, formerly Le Chat, is Mistral AI's assistant, relaunched in May 2026 as an agent that can work through longer tasks across your email, calendar and documents. Answers come fast, and it covers web search, deep research, image generation and a Code mode for programming. Being a French company that favors EU providers is a plus if you care where your data goes. Its models still trail the top US labs on hard reasoning.

Dia
- Calm, uncluttered design from the makers of Arc
- Data is stored and encrypted on your device
- AI partners are barred from training on your data
- New users' free plan has no AI features
- Better Days plan costs $100 a month
- Windows version is still an early build
Dia comes from the team behind Arc and puts an AI chat beside your tabs that can read what's open and pull in context from Slack, Notion and Teams. Its Morning Brief, meeting prep and deck building are aimed squarely at office work. Privacy is better than most AI browsers, with your data stored on your device. Since August 2026, though, new users get no AI on the free plan, and the Windows version is still young.
