Jevvie — Chris Wijnia
Jevvie is the companion in the corner of every page on chriswijnia.com: ask it for something and Jev picks which of the page's actions you mean, one typed Choice at a time, then Jevvie hops over and does it. The same actions are WebMCP tools.

Highlights
- Ask it for something and Jev picks which of the page's actions you mean, one typed Choice at a time.
- When Jev is unsure it asks instead of guessing; it offers a tip now and then and mostly chooses to stay quiet.
- Double-click for a trick, right-click for its menu, and in the studio it takes any body or mood and saves a frame as a sticker.
- The same actions are WebMCP tools: with WebMCP or the MCP-B extension an agent can drive the site while Jevvie narrates.
Watch out
Grounded on the page text captured on 2026-10-15, which mirrors the page's panel text; no pricing, account requirements or implementation details beyond the WebMCP tools and the System One model credit appear in the capture. Agent control needs a browser with WebMCP or the MCP-B extension.
Questions about this entry
Short answers drawn from the linked project or page.
The site's companion, living in the corner of every page on chriswijnia.com, this one included. Click it and ask for something; Jev, TypeSafe AI's System One model, picks which of the page's actions you mean, one typed Choice at a time, and Jevvie hops over and does it.
It asks instead of guessing. It also offers a tip now and then and mostly chooses to stay quiet, so the companion does not act without a clear choice.
Double-click it for a trick and right-click for its menu. In the studio you can put it in any of its bodies and moods, make it do a trick, and save the frame as a sticker.
Yes. The same actions Jevvie performs are exposed as WebMCP tools: in a browser with WebMCP, or with the MCP-B extension, an agent can drive the site with them, and Jevvie narrates what it does.
Jev, TypeSafe AI's System One model, called for the typed Choice that maps your request to one of the page's actions. The panel on the page also exposes what an agent in your browser sees and what Jevvie chooses from.
No pricing, account or key requirements appear in the captured text. It is a feature of chriswijnia.com's pages rather than a separately installed product.
There is no distribution described in the capture; Jevvie lives on chriswijnia.com's pages. The page shows a source link marker, but the digest does not record a repository, licence or embed instructions.

A website companion's code: a page's actions are offered as WebMCP tools, a visitor's request becomes one Jev Choice, and a three.js voxel character hops to the button and does it.

An independent lab for trying the Jev model: a customer-message example plus experiments for task routing, context selection and evidence checks. It shows choice, score and boolean answers with probabilities and can export the request as TypeScript.
