What it is
A Manifest V3 Chrome extension that automates the tab you are looking at, using your own cookies and logins. It is a community port of browser-use/jev-ultrafast, not affiliated with TypeSafe or Browser Use.
How it uses Jev
Each step, one Jev request carries the goal, element table and recent actions; a Choice picks the operation and element, while two Noul checks (goal reached, stuck) veto a premature DONE or BLOCKED. A small text model writes typed text only.
Primitives:choicenoul
Technique worth stealing
Two independent Noul checks cross-check DONE and BLOCKED without seeing the action choice.
Try it
Load the extension in Chrome, type a goal in the popup.
Evidence
Each line is one question put to Jev about the README. ≥ 0.60 reads as yes, ≤ 0.40 as no; in between Jev is not making a call.
