Chrome preview
Install Project Atlas locally.
The preview is not in the Chrome Web Store yet. Chrome labels locally loaded extensions as unpacked; only install the package from this official page.
Unzip the download
Keep the resulting project-atlas folder somewhere you will not delete.
Open Extensions
Enter chrome://extensions in Chrome’s address bar.
Enable Developer mode
Turn on Developer mode in the upper-right corner of the Extensions page.
Load unpacked
Choose Load unpacked, then select the unzipped folder containing manifest.json.
After installation
Pin Atlas from Chrome’s Extensions menu. The toolbar popup saves and restores contexts; the side panel searches live tabs; the dashboard reviews local organization suggestions.
Updating the preview
Download the newer package, replace the old folder contents, then choose Reload on chrome://extensions. Local contexts remain in Chrome storage.
