How it works

From intent to done — in three steps.

01Step

Pin the extension

Add Agentronics to Chrome in one click. Sign in, drop $10 into your wallet, and pick a model — Claude, GPT, or Gemini.

02Step

Press ⌘K, say what you want

On any website — Amazon, United, Zillow, LinkedIn — press the shortcut and type the task in plain English. No scripts, no setup.

03Step

Watch it finish the job

Agentronics clicks, scrolls, fills, and compares for you. You stay in the loop — pause it, correct it, or just walk away.

What it can do

If the web can do it, Agentronics can do it for you.

Not a chatbot. Not a plugin. A real browser agent that clicks, types, and scrolls like you would — only faster, and without getting bored.
