Agent readiness & answer capture, on every store you visit

One click on any storefront: readiness score, verdict, UCP/MCP and AI-crawler access. And on ChatGPT, Gemini, Rufus and friends, capture the shopping answer you’re seeing into ACOS as observed ground truth.

Is it safe? Yes — and you can verify it yourself

The whole thing is 3 short text files

No build step, no bundler, nothing hidden. Read every line before you install — links below open the exact source this download contains.

Minimal, explained permissions

activeTab (only the tab you click on) · scripting (reads the visible answer only when you press Capture) · storage (remembers your Cloud/Local choice). No “all sites” access, no background access.

Capture takes a screenshot — of that tab, only on click

Pressing Capture screenshots the visible area of the current tab (so you keep visual proof of what the agent showed) and uploads it to your ACOS for review. Whatever is on screen is in the image — if the assistant’s sidebar shows your name, email or chat history, crop or close it first. Screenshots are stored privately in your workspace and you can delete them at any time.

Nothing happens automatically

It only acts when you click. Captured answers and screenshots open a review form in your ACOS — nothing is attached to a saved answer until you confirm.

No tracking, no third parties

It talks only to your ACOS instance (the readiness API and the capture form). No analytics, no telemetry, no data brokers.

Read the exact source you’re installing

These are the exact files inside the .zip above. What you read is what runs.

Chrome Web Store listing coming. Once published, you’ll install in one click and get Google’s independent review, a verified publisher, and automatic updates — the strongest safety guarantee. This developer-preview download bridges the gap until then.

Privacy: the extension sends the current tab’s domain to your readiness API when you click it. When you press Capture it sends two things, and only then: the sellers/prices it reads from the page, and a screenshot of that tab’s visible area — which contains whatever is on screen at the time. Both go to your own ACOS for you to review before anything is saved, are stored privately in your workspace, and can be deleted at any time. Nothing is read or sent otherwise, never automatically, and never to anyone but your own ACOS. See the privacy policy.
