Projects that provably run on Jev.
Jev is TypeSafe AI's System One model: state and a typed question in, a constrained answer with a probability out. Every project here links to the line of code that makes the call. Mentions, forks and catalogues are left out, and what is left out is published too.

SDKs & clients. A library whose whole purpose is talking to the System One API from one language or runtime: request signing, typed Choice/Score/Noul answers, retries. Not here: Applications that happen to ship a thin wrapper, and provider adapters that live inside a larger framework (those are integrations).
Integrations. An existing framework, platform or product that gained Jev support: a provider, adapter or plugin inside a codebase that is not about Jev. Not here: Standalone tools built around Jev from the start.
Agent tooling. Tools that sit in an AI agent or developer workflow and use typed decisions to act: tool-call gates, routers, guardrails, MCP servers, code review, CLIs. Not here: General applications that merely call a model, and browser automation (its own section).
Browser & computer use. Drives a browser, desktop or operating system, deciding what to click, type or do next from page or screen state. Not here: Scrapers and extensions that never decide an action.
Applications. A product or hosted service someone uses, where a Jev decision is part of what it does: moderation, triage, matching, scoring, pricing. Not here: Examples and experiments with no users (those are demos), and internal libraries.
Games & simulation. A game, robot controller or physics simulation where Jev reacts to game or sensor state, usually in a loop. Not here: Game-themed demos with no running loop.
Demos & playgrounds. Built to show or learn one thing: examples, playgrounds, starters, tutorials, weekend experiments. Not here: Anything with real users or a published package.
Benchmarks & research. Measures Jev: benchmarks, calibration studies, accuracy or latency comparisons, reproductions, datasets. Not here: Projects that merely report a benchmark number in their README.
