Visualize & Learn is a browser extension that explains what you're reading or watching, in chat and with interactive visuals. This policy explains what data it handles, where that data goes, and what stays on your device.
The extension is off by default. It does nothing on a page until you click its toolbar icon to turn it on for that tab. You can turn it off again from the icon or from Settings.
Only when you ask it something (by sending a message, clicking Visualize, picking a suggestion, or using a shortcut or the right-click menu), the extension reads from the current tab:
It does not read pages in the background, and it does not access your browsing history, bookmarks, passwords, cookies or other tabs.
Anthropic. The content above, together with your messages, is sent directly from your browser to Anthropic's API (api.anthropic.com) using your own API key, to generate answers and visuals. Anthropic's handling of that data is described in its privacy policy: https://www.anthropic.com/legal/privacy
Google (voice input). If you use the microphone, your browser's built-in speech recognition turns your speech into text. In Google Chrome, Google processes that audio.
Google (early-access sign-up). The extension includes an optional "Get early access" link to a Google Form. Nothing is sent unless you open the form and submit it yourself. If you do, the form collects your email address and your answers to a few short questions (what you want to learn, where you learn, whether you have an API key, and what you'd pay). The developer uses this only to contact you about the hosted version and to plan it, and will not sell or share it. Google stores form responses under Google's privacy policy: https://policies.google.com/privacy. To have your sign-up deleted, email the address below.
The extension has no server of its own. The developer does not receive, store or see your pages, messages, visuals, usage or API key.
In your browser's local extension storage, which never leaves your device:
