Description
Inspects whether the ChatGPT Ads measurement pixel is installed and firing on any website. Live event log, misuse alerts. Pixel Checker for ChatGPT is a developer tool that tells you, on any website, whether the ChatGPT Ads measurement pixel is installed and actively firing. It is built for advertisers, marketers, growth engineers, and QA teams who need to confirm that their conversion tracking is working before they spend ad budget — or who are auditing a third-party site they're considering as a partner or competitor. ▸ What it answers • Is the official pixel SDK loaded on this page? • Has oaiq("init", { pixelId, ... }) been called, and with which Pixel ID? • Is debug mode on? • Which events have actually been measured on this tab, with what payload? • Is the first-party __oppref cookie set? • Is the page mistakenly calling the server-only /v1/events endpoint from the browser? (a common misconfiguration that breaks attribution) ▸ How it works The extension runs entirely on your device. A small page-world helper hooks the window.oaiq global at document_start and captures every init / measure call, including event_id, custom_event_name, and the full event payload. A service-worker-side webRequest listener corroborates the in-page signal by watching for the pixel SDK script and outbound beacons. The popup, the toolbar badge, and an optional "Pixel Checker" DevTools panel show the results in real time. ▸ Toolbar badge at a glance • ON (green) — installed, initialized, and measuring • • (green) — initialized, no events captured yet • ? (amber) — SDK loaded but no init() call observed • ! (red) — browser is calling /v1/events directly (misconfiguration) • (empty) — pixel not detected on this page ▸ What you can see in the popup • Pixel ID(s) — copyable, deduplicated across multiple init calls • Debug mode flag • A live, expandable list of every measure call with full JSON detail (event name, props, options, event_id, custom_event_name) • Outbound beacon count • __oppref cookie status • One-click "Copy report" that produces a shareable JSON snapshot ▸ DevTools panel A dedicated "Pixel Checker" tab in Chrome DevTools shows a live, filterable stream of every oaiq(…) call on the inspected page, with timestamps down to the millisecond. ▸ Privacy This extension does not collect, transmit, or share any data. There is no analytics, no telemetry, no remote code, no developer-side server. All state lives in the Chrome service worker's memory and is cleared when you close the tab. See the privacy policy linked from this listing for full details. ▸ Demo site A fake brand called Lumen ships with the source code (in the demo/ folder) so you can verify the extension end-to-end without spending real ad budget. The homepage alone fires eight distinct event types as you click around. ▸ Disclaimer Pixel Checker for ChatGPT is an independent third-party developer tool.
