How it works

From a first score to a fix you can prove, in four steps.

  1. 01

    Check your domain

    Enter it above. A domain we already track opens its report straight away. A new one gets its first report built live: quick checks of what agents can reach, then Claude, ChatGPT and Gemini trying real tasks in a real browser.

  2. 02

    Read the report

    One overall score and its rank, a score per category and per agent, and the friction that stopped them, each backed by the run it came from. The methodology explains every check.

  3. 03

    Fix what blocks agents

    Every report carries a fix prompt: the failing checks and frictions, written up for your coding agent. Paste it in, ship the fix, and the next run shows whether it worked.

  4. 04

    Claim it

    Sign in with a work email on the domain to claim it. Owners replay every agent session in full, edit how the domain is presented and request a re-run whenever they ship. Personal inboxes like Gmail can't prove ownership.

Go past the public tasks

The Index runs the same tasks for every site in a sector. Stunt Double puts agents and AI personas through your own flows, signed in, with the evidence to show what broke.
