Works perfectly, does exactly what it's supposed to do (and has a really pretty UI).

AI product read

Automatically close browser tabs after a user-defined delay

Prevents tabs from staying open overnight or during long browsing sessions, reducing memory usage and helping users avoid distraction or accidental tab accumulation.

User clicks the extension icon → sets a time delay (or selects a preset) → clicks Start → the service worker schedules an alarm to close the tab after the specified time → a countdown is shown in the popup and a badge on the tab → user can cancel at any time.

Target users: Night browsers who fall asleep with tabs open / Users seeking a digital detox or focus aid / Anyone wanting to prevent tab clutter

The extension is very small (18 KiB) and self-contained; no external API calls or server-side logic to analyze. The analysis is based entirely on static code inspection of the 10 files in the source package.

Monetization

No paid features detected

No payment, subscription, billing, or upgrade logic exists in the code. The extension is entirely free with all features available. The keyword 'pro' found in _metadata/verified_contents.json is part of Chrome Web Store's signed-content metadata, not a paid tier.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local utility that uses only chrome.storage.session and chrome.alarms. There is no login UI, no account creation, no external authentication, and no reference to any web service requiring an account. The core workflow (setting a timer to close a tab) works entirely offline within the browser.
