Install chanio in 60 seconds

chanio is in Chrome Web Store review. While we wait, you can install the dev build directly. It's the same code that ships to the store — unzip, load, done.

Download chanio-extension.zip Open chrome://extensions

Works in Chrome, Arc, Brave, Edge, and Opera. Manifest V3. No background tracking.

Download the extension

One zip, 13 KB. Unzip it somewhere you can find again — the folder stays on your machine.

Open chrome://extensions

Paste that into your address bar. Same menu for Chrome, Arc, Brave, and Edge.

Toggle Developer mode

Top-right switch. This unlocks the Load unpacked button. You'll toggle it off once we're in the Chrome Web Store.

Click Load unpacked → pick the chanio folder

Select the unzipped chanio-extension folder (the one with manifest.json inside). chanio installs instantly.

Pin chanio and start surfing

Click the puzzle icon in your toolbar, pin chanio, then browse like normal. It learns your channels passively.

What chanio reads, and what it does not

ReadsTitles, URLs, visible text on pages you actively browse.

StoresLocally on your device. Nothing leaves unless you explicitly share.

Never touchesPasswords, payment fields, private tabs, inputs flagged sensitive.

Open sourceEvery line of content.js and background.js is readable in the zip.

After you install

Try the healthcare channel first

Visit any of the condition sites — hearthealth.help, hippain.help, memoryloss.help — and chanio starts building your quiet map. When you open a new conversation in Claude, your Sage already knows what you've been reading.
