About JEV Ultrafast Agent

Jev Ultrafast Agent is a browser extension that automates tasks on web pages, such as filling forms and clicking buttons, using a language model of your choice. It reads the page as a numbered list of interactive elements and returns a typed decision for each action, ensuring speed and efficiency. This open-source project requires no local server or additional tools, making it easy to use with various API providers.

JEV Ultrafast Agent FAQ

Does it need a local server or Python?

No. It is a pure Chrome extension. Everything runs in the browser.

Which models can I use?

Claude (Anthropic), any OpenAI-compatible API (OpenAI, OpenRouter, Groq, DeepSeek), local models (Ollama, LM Studio), or TypeSafe Jev.

Is my data sent anywhere?

Only the page content and task go to the model endpoint you choose. No analytics, no central backend, API keys stay local.

Can it bypass CAPTCHAs or logins?

No. It works only on pages you can already interact with manually.

How is it different from other browser agents?

One typed decision per step (CLICK, TYPE, SELECT, etc.), indexed elements, re-observes the page if it changes, and is fully token-efficient.
