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

1. Open the HAEVN page on the Chrome Web Store (link coming soon).

2. Click Add to Chrome.

3. In the confirmation dialog, click Add extension.

4. 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:

1. Open chrome://extensions in your browser.

2. Enable Developer mode using the toggle in the top-right corner.

3. Click Load unpacked.

4. Select the dist/ folder from your HAEVN build.

5. The extension will load and the HAEVN icon will appear in your toolbar.

Caution

Manually loaded extensions are not auto-updated. You’ll need to reload the extension and click Update whenever you install a new build.

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.

Permissions

HAEVN requests the following browser permissions:

Permission	Why it’s needed
Storage	Saves your synced conversations locally
Tabs	Detects which AI platform you’re currently on
Scripting	Injects a content script to read conversation data
Host permissions	Accesses the APIs of each supported platform

Note

All data stays in your browser. HAEVN does not send anything to external servers. See Privacy & Storage for details.
