Claude and Mistral Vibe, briefly
Claude is Anthropic's assistant. Mistral Vibe (ex-Le Chat) is the assistant from Mistral AI, a French company. It was renamed on 28 May 2026 and is still at the same address, chat.mistral.ai.
What the import tools do
- Claude can take on what other AIs know about you. According to Anthropic's help pages, you run a prompt in your current AI and paste its answer into Claude. Anthropic calls the feature experimental. It's an import into Claude, not a profile you can take anywhere.
- For Mistral Vibe, check Mistral's help pages for what's offered when you switch.
An import isn't a handover.
Even when your profile or history comes along, the new assistant doesn't know what's been decided in one specific piece of work, what you dropped along the way, or what comes next. To carry on that work, it needs a short opening message.
Carry a conversation over by hand
You're picking up work I started in ChatGPT. Here's what you need to continue. GOAL: [what we're doing or deciding] DECIDED (don't reopen): - [decision 1] - [decision 2] RULES: - [tone, format, length] WHERE WE ARE: [current state] NEXT: [the next step] Confirm you've understood, then help me with the next step.
Send it first in a new Claude or Mistral Vibe chat. Uploaded files, images, ChatGPT's memory of you and your custom instructions don't come along: add them again if you need them.
The faster way: Handoff in Uncook
Handoff in Uncook writes that opening message for you, addressed to the AI you're moving to. Open the conversation in ChatGPT, click the Uncook icon, choose Handoff, turn on Switch to another AI, then where you're going:
- Claude: paste the prompt.
- Mistral Vibe: copy the prompt and send it first in a new Mistral Vibe chat.
You get the decisions, the reasons you gave and the questions still open. It works the other way too: the extension also reads Claude and Mistral Vibe chats.
FAQ
Will Claude or Mistral Vibe answer like ChatGPT? Not exactly: each has its own style. Put the tone and format you want in the rules of your prompt.
Can I move a chat to Grok? You can copy a Handoff prompt into any AI by hand. But Uncook doesn't read Grok chats, so you can't bring one back with Uncook.
Does it work on my phone? Uncook is a Chrome extension for your computer. On your phone, write the opening message by hand with the template above.

We don't keep the conversations you bring. When you click Send to Uncook in the extension window, the extension sends the chat from your tab to our servers, encrypted, for up to 30 minutes, and we delete it as soon as your Uncook page opens it. What Uncook makes from it is kept as a task, for as long as our Privacy page says. Neither your chats nor your tasks are used to train AI models.
