What Jev is: an 18K-star decision model and 10 live projects
Jev only makes decisions and does not execute: given a state and a question it returns a decision while code handles execution, with 10 examples including browser click prediction, Claude Code context selection, Mac control, Android automation, code review, trading, tax classification and Postgres Q&A.
18K+ STARS FOR AN AI THAT DOESN’T CHAT OR WRITE. It just makes the call. That’s JEV. You give it a state and a question, it returns a decision, and your code handles the execution. That simple idea is already being used across browser agents, coding tools, trading, tax software, databases, and mobile automation. 10 projects already live: JEV-ULTRAFAST Predicts the next browser click. 18K+ GitHub stars. https://github.com/browser-use/jev-ultrafast FAST-JEV-COMPACTION Decides which tool calls Claude Code should keep and which ones it should drop. 6.5K+ stars. https://github.com/tamaratran/fast-jev-compaction JEV-CHAT-JARVIS Reads a chat screen and ranks possible replies without ever sending one. https://github.com/jev-chat/jev-chat-jarvis TYPESAFE-COMPUTER-USE Lets software control a Mac for roughly $0.0002 per step. https://github.com/awlevin/typesafe-computer-use MOBILE-JEV Brings the same decision loop to a real Android phone. https://github.com/droidrun/mobile-jev JEV-REVIEW Reviews a git diff and returns risk, evidence, and severity. https://github.com/devagrawal09/jev-review JEV-TRADER Makes a buy, sell, or hold decision on every Monad block. https://github.com/jarrodwatts/jev-trader TAX-DOC-CLASSIFIER Classifies IRS page types for roughly $0.001. https://github.com/kyotofin/tax-doc-classifier PG-JEV Lets you ask questions about Postgres tables in plain English. https://github.com/realZachi/pg-jev KILLMYIDEA Evaluates a startup idea and tells you whether to kill it, fix it, or ship it. https://github.com/monteduro/killmyidea The interesting part is that JEV is not trying to do everything itself. It sits between the current state and the next action. That is why the idea is interesting. JEV makes the decision. Your software does the work.
