The #1 directory of projects built with Jev

What is Made with Jev?

A directory of projects built with Jev, the System One model from TypeSafe AI. It is one place for the things people ship with it: repos, demos, agents, browser extensions, trading loops, games, plus the posts and guides that explain how they work.

Entries are sorted by what the build does, not by who made it, across 8 use cases — from agents and browsers to triage and routing. Every entry links straight to its source, so nothing here asks to be taken on trust.

How did Made with Jev get started?

Jev launched on 15 September 2026, and I have been obsessed with it since. A model that only decides, in under half a second, for a fraction of a cent, changes what a small team can even try to build. So I went down the rabbit holes.

What I found was better than the launch demos. Someone had Jev flying a drone. Someone sorted a thousand research papers with it in a minute. Someone wired it into a browser agent that books flights. I started saving the good ones, the list outgrew my notes, and a few days after launch it became this site.

It is still the same job, only in public: read everything, keep what holds up, throw the rest away. Now other people add to it too.

What gets listed, and how?

Builds are picked by hand, and the bar is plain:

• A public link anyone can open — a repo, a post, a live page. No private demos.
• Something that actually runs, or a write-up worth the read. An announcement of an intention is not a build.
• Jev doing the deciding somewhere in it, not just named in passing.
• Any cost or speed figure shown is the one its author published, next to the link where you can check it. Nothing on this site is measured here.

Listing is free and cannot be bought. Paid placements exist, they are marked in amber, and they never sit in the feed pretending to be a listing. The sponsor rules spell that out.

Can I share what I built with Jev?

Yes, and that is the part I like most. Drop a link on the community page and Jev judges it itself: it opens the page, decides whether it belongs here and sorts it into a use case, in one call. What clears the bar is live the same second — no queue, no inbox, no me. 24 links have gone through it so far.

The community lane and the curated directory stay separate on purpose. The keepers get promoted into the main feed by hand. If you would rather I look at yours myself, use the submit page.

Who is behind Made with Jev?

One person: me. I read the submissions, write the entries and keep the guides current.

Solo founder. I build and ship my own products, and I curate this directory. If you are building with Jev and want a second pair of eyes on it, say hello on any of these.

Is Made with Jev affiliated with TypeSafe AI?

No. This site is independent. TypeSafe AI does not run it, review it or pay for it, and nothing here is an official source on the model. For that, read their launch post and their docs.

One naming note, because search keeps confusing them: the Jev listed here is TypeSafe AI’s System One model. It is not Japanese encephalitis virus, which shares the letters JEV.

How is the directory paid for?

Sponsor slots, and that is all. They are marked in amber so an ad never reads like a listing, and buying one does not buy an entry in the feed. The free tools stay free. If the site is useful to you and you want to chip in, there is a coffee button below.
