Fudici

For AI agents in your browser

Set the rules for your AI agent. See what Fudici would have stopped.

Fudici watches what AI agents do in your browser: the sites they use, the forms they fill in and what they buy. When an agent breaks one of your rules, you see the step and the rule it broke. It only watches; nothing is blocked.

  • ChatGPT
  • Claude

ChatGPT on its own site. Claude and other agents on any site once you tell Fudici an agent is working in the tab.

Get startedSee how it works
An animation of Fudici at work, with ChatGPT as the example agent: it buys a phone on demoblaze.com, the Fudici button in the toolbar shows a red mark, its popup names the $100 purchase rule the step broke, and Home asks whether Fudici should have stopped it and records the answer. The data is an example.

Rules

Your limits, in plain words.

Fudici starts with two rules: a purchase over $100 and a first time on a site. Add a monthly limit, or change them any time.

An animation of the Rules page: the monthly limit is turned on, the purchase limit changes from $250 to $100, and Save rules says the extension in this browser has the new rules. The data is an example.

Watch mode

It shows what it would have stopped.

Break a rule and the extension marks it at once. Home lists the step and asks whether Fudici should have stopped it. Nothing is blocked.

An animation of Home: two steps a rule caught arrive, each gets an answer, and each rule's count updates. The data is an example.

Every run

Everything your agent did, on one page.

Not just purchases: the searches it ran, the sites it used, the forms it filled in and what it bought, step by step. Each step Fudici records is signed on your computer, so a later change to the record would show.

An animation of Activity: each step of an agent run, with ChatGPT in this example, appears as it happens, from a web search to a purchase whose result the page never showed. The data is an example.

Privacy

Your browsing stays with you.

On sites other than ChatGPT, Fudici records only once you turn on “Watch agents on every site”, and only in a tab where an agent is acting, not while you browse on your own. Chats and page text stay on your computer. Fudici receives a short record of each step, such as the site, the action, any amount and how it ended.

The extension welcome page: three steps done, the two rules Fudici starts with, then what Fudici receives and what stays with you.

Let your agent work. Keep your rules.
