Builds made with Jev

Kyle McLaren released JevQL, which lets vanilla Postgres filter rows by meaning using Jev, with no extension, plus a CLI, SDKs and MCP support.

Max Libin built a 3D cube where code does the solving and Jev coaches you, staying quiet while you progress and warning or suggesting a next move after mistakes.

Akash Purjalkar built a Minecraft bot where Jev decides actions: it constructs houses, towers, lakes and castles on command and fights mobs while dodging skeleton arrows.

Elena Joseph built a firewall between a coding agent and your computer where Jev judges each tool call before it can touch the machine.

Divine Machine open-sourced a desktop agent that uses Jev for computer use and says it was about 10x faster than a frontier model's native computer use in limited tests.

A Claude Code user published a toolkit that lets Jev judge selected tool calls, size subagents and choose browser actions, and measured the effect on real sessions.

Davernow tuned a custom Jev harness with context hints and chained decisions to choose Chinese pronunciations, reporting about one seventh of the cost and one thirtieth of the latency of DeepSeek.

The author added Jev to a Chrome extension so it chooses the best saved prompt, template or workflow for a goal even when your search words match nothing.

Jev-gc watches an agent's OpenTelemetry spans and has Jev decide what stays in the next prompt, what turns into a pointer and what gets archived.

Jevals turns agent checks into typed questions so the same evaluation definitions run on saved traces and as live guardrails using Jev-style decisions.

Davertor built an open-source Chrome extension where Jev scores each post for AI slop and blurs anything over your chosen threshold, with a button to reveal it.

A founder rebuilt their survey-research workflow around Jev and reports it came out 85% cheaper and twice as fast as Gemini Flash-Lite on 200 samples.

A Reddit builder launched real8ball.com, a free site where Jev answers your question like a magic 8 ball.

Cheeaun built an open-source app that scores more than 3,000 emojis against whatever you type with Jev and shows the best matches, a playful take on Jev ranking.

Eluewisdom wrote a small Elixir library for Jev that works with TypeSafe and OpenRouter and supports yes/no, choice and score questions, several per request.

Jive is an open-source terminal coding agent whose execution graphs mix tool calls with Jev decisions so a frontier model is used only where needed; six tasks ran in about 1.7 to 3.4 minutes.

The author maps an accessibility snapshot to the next browser action with Jev, reporting around 153 ms median per decision and a four-step form fill in 3.4 seconds.

A Reddit builder shared a router where Jev decides per request whether a local Qwen model or hosted Sonnet should answer, with a UI that shows each routing decision.
