Something not working?

The very first time you use Lens, it downloads the AI model (roughly 200–300MB) so it can run fully on your device from then on. This only happens once — every analysis after that is fast, and repeat analyses of the same image are instant thanks to Lens's local cache.

If it seems stuck rather than just slow, check your internet connection for that first download — after that, Lens needs no connection at all.

This almost always means the tab was already open before Lens was installed or updated — Chrome doesn't retroactively inject extensions into existing tabs.

1. Refresh the page you're trying to use Lens on.
2. If that doesn't help, go to chrome://extensions and click the reload icon on Lens's card.
3. Confirm Lens is enabled and not paused for that site under "Site access."

This is a known, harmless message from the AI runtime cleaning up unused parts of the model graph while it loads — it doesn't affect your results. Recent versions of Lens filter this out of the console automatically.

This was a real bug in earlier builds, caused by the AI runtime trying to use a background worker thread that doesn't work inside a Chrome extension. It's fixed as of the current version.

If you still see this: update to the latest version, then fully remove and reinstall the extension so any partial model download gets cleared out.

Make sure you're clicking the button itself (not just viewing the card) — browsers only allow clipboard writes in direct response to a real click. Then try pasting into any text field to confirm; some sites' own paste handling can interfere with what you see immediately after, but the clipboard content itself is set correctly.

Go to chrome://extensions → Lens → Details → Clear storage. This removes all locally cached captions/tags; nothing needs to be cleared on any server, because there isn't one.
