Jev Ultrafast Agent is a Chrome-based AI browser agent that replaces screenshot-heavy automation with an indexed action space. Instead of repeatedly sending screenshots to a vision model, Jev turns interactive page elements into structured inputs and lets the AI execute typed actions like CLICK, TYPE_TEXT, SELECT and SCROLL. It runs directly in Chrome with no Python or local server required. Bring your own model and API key - including Claude and OpenAI-compatible APIs.
