Jev routesMistral writes

Two models,
one chat.

Jev reads every message and picks the shape of the answer: a plan, its reasoning, a diagram, or prose. Mistral writes it.

An illustrative replay of four messages. In the app, every reply streams live from Mistral.

You ask: “Schema's drafted. Plan the rest of our move to GraphQL.” Jev routes it to plan with 0.91 confidence. Mistral may only call showPlan. Mistral replies with a plan card: two steps done, one in progress, two to go.

How it works

Two models, two jobs.

Jev never writes a word. It answers one typed question about your message, and that answer decides which tools Mistral is allowed to use.

  1. 01

    You ask

    Type anything into the prompt box. Pick Codestral or Ministral 3B, and switch whenever you like, even mid-conversation.

    Plan the rest of our move to GraphQL.

  2. 02

    Jev picks the shape

    One question, five possible answers: plan, reasoning, diagram, audio, or plain chat. It's a single classification, not a second chat turn.

    jev → plan · 0.91

  3. 03

    Mistral writes it

    Only the matching tool is on the table, so a plan comes back as a plan. The reply streams in word by word and lands in your history.

    showPlan ▸ streaming…

When Jev isn't sure, it steps aside.

Below 60% confidence, or if Jev can't be reached, Mistral gets every tool and picks for itself. Routing gets less precise; the chat keeps working.

Formats

Not every answer is a paragraph.

A tool call lets Mistral answer as interface, rendered straight from the call with no extra round trip. Everything else comes back as prose.

showPlan

Plans

A titled plan with every step marked done, in progress, or still to come.

showChainOfThought

Reasoning

The working, laid out step by step before the answer.

showCanvas

Diagrams

Concepts drawn as nodes and edges on a canvas, right in the thread.

no tool

Prose and code

Markdown that stays tidy while it streams, with highlighted code, math, and Mermaid charts.

  • History that stays

    Every chat and message is saved to your account. A refresh or a new tab loses nothing.

  • Pin, rename, search

    Pin what matters, rename anything, search the rest, and delete what you don't need.

  • Stop mid-reply

    Cut a reply off the moment you've seen enough.

  • Regenerate

    Ask for another take on the last answer. The new one replaces it.

  • Edit and resend

    Fix a message you already sent, and the thread picks up again from there.

  • Feedback

    Thumbs up or down on any reply, saved with the message.

  • Copy

    Copy any reply in one click.

  • A real account

    Email and password sign-in, password reset, and account deletion when you're done.

Ask it anything.

Jev picks the shape. Mistral writes it. Your history stays put.
