Browser Annotations is a Chrome DevTools extension that grabs element context and lets you add annotations to send to coding agents.

It runs entirely on your machine. There is no server, account or analytics.

The extension handles a few things while you use it:

• - The annotation text you type
• - DOM context of the element you select — selector, position, size, viewport, device info, and the page URL
• - An optional screenshot of the selected element

Annotations, your webhook URL, and the send toggle are stored locally with chrome.storage, scoped per website, so you can batch feedback across page loads. Clearing extension data in Chrome removes them.

Webhook sends embed the screenshot inline in the request body. Copies save it to your Downloads folder under browser-annotations/ so your agent can read it from disk. Delete the folder to remove saved screenshots.

The data goes only where you tell it to — your configured webhook (your own Pi or Claude Code session), or your clipboard. Nothing is sent to me or to any third party.

• - No tracking across sites
• - No selling or sharing of data
• - No use for advertising or creditworthiness
• - No remote code execution

Three permissions are requested, all for the core feature:

• - storage — to persist annotations between page loads
• - downloads — to save screenshots to disk so your agent can read them
• - <all_urls> — so the extension can read element context and capture screenshots on whichever site you happen to be debugging
