Download & use

1. Download the zip (when available) and unzip it somewhere permanent (e.g. Documents\chip-for-beta). Chrome loads the extension from this folder, so don't delete it afterwards.
2. Open Chrome and go to chrome://extensions.
3. Turn on Developer mode (top right).
4. Click Load unpacked and select the unzipped folder (the one that contains manifest.json).
5. The glasses icon appears in the toolbar. Pin it if you like. Refresh any tabs that were already open.

1. Take the Beta Test and click Download settings for this level. You get a small .json file.
2. Right-click the extension icon → Options.
3. Under 备份与安全 (Backup & security) click 导入设置 (Import settings) and choose the file.
4. Done. Everything else stays at the extension's defaults; you can still change the style, threshold or whitelist later.

Default style is a black block at a 0.20 confidence threshold with 15% margin. GPU (WebGPU) is used when available, otherwise CPU.

• Chrome 116 or newer (also works in Edge / Brave / other Chromium browsers with the same steps).
• Permissions explained: storage saves settings; offscreen documents run the local model; alarms remove temporary rules; the scoped network rule helps repair certain cross-origin video frames; host access lets the extension inspect media on enabled pages. No media or browsing history leaves your machine.
• Updating: download the new zip, unzip it over the old folder, then click the reload icon on chrome://extensions.
• Chrome may show an "unpacked extensions" reminder on startup. That's expected for anything not from the Web Store.
• Source is AGPL-3.0-or-later. The model and runtime notices are in the zip under THIRD-PARTY.md and licenses/.
