YouTube only shows relative time like '3 days ago' rather than the exact publication timestamp. This extension lets users see the precise date/time a video was published or a live stream started.

1. User navigates to a YouTube video page. 2. The content script (dt.js) detects the page and inserts a '詳細' button next to the video title. 3. User clicks the button. 4. The extension sends the video ID to background.js, which fetches data from a Cloud Run proxy server. 5. The proxy returns video metadata including publication time or live stream start time. 6. The exact local date/time is displayed next to the video title.

Target users: YouTube viewers who want to know the exact time a video was published / Japanese-speaking YouTube users (UI is in Japanese)

The proxy server at detailedtime-server-1055222665673.asia-northeast1.run.app is a backend service — its internals (e.g., whether it uses a YouTube API key or has rate limits) cannot be inspected from the extension source alone

Monetization

No paid features detected

No payment UI, no billing APIs, no subscription/upgrade gates. All keyword hits are false positives: 'pro' matches are from 'proxy' (proxyUrl, Proxy server) in background.js and jQuery internals, 'license' is the jQuery library license header. A commented-out section references a developer donation/support link, but it is entirely inactive.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login UI, no auth tokens, no credentials flow. The extension works directly on YouTube pages without user authentication. The proxy server fetches data server-side on behalf of the user. The 'auth' keyword hit in manifest.json is the 'author' field (@nulltypo) — a false positive.
