Installation

HAEVN runs as a Chrome extension (Manifest V3). It requires Chrome or any Chromium-based browser (Edge, Brave, Arc, etc.).

Install from the Chrome Web Store

Open the HAEVN page on the Chrome Web Store (link coming soon).
Click Add to Chrome.
In the confirmation dialog, click Add extension.
The HAEVN icon will appear in your Chrome toolbar. If you don’t see it, click the puzzle-piece icon (Extensions) and pin HAEVN.

Install manually (developer / early access)

If you have a local build or a downloaded .zip of the extension:

Open chrome://extensions in your browser.
Enable Developer mode using the toggle in the top-right corner.
Click Load unpacked.
Select the dist/ folder from your HAEVN build.
The extension will load and the HAEVN icon will appear in your toolbar.

Install the CLI (optional)

If you want terminal access to your archive (search, branch navigation, imports/exports):

npm install --global @haevn/cli

Then run:

haevn --help

See the CLI guide for full setup.

Verify the installation

Click the HAEVN icon in your toolbar. A small popup will appear showing the HAEVN interface. If you’re on a supported platform (like ChatGPT or Claude), you’ll see sync options. If you’re on any other page, it will show a list of supported sites to visit.

Click Archive in the popup to open the full archive manager — this is your home base for browsing, searching, and managing all your synced conversations.
