This extension works pretty well enough for being able to see comments and timestampts listed though i wished there was an option to make it so it automaticly shows the relevant timestamped comment as the video plays, Some videos can have big amounts of timestamped comments which having this option would make it less of a hastle to being able to check out every comment if one wanted to

これがないYoutube視聴生活はないと断言できるツールですただ問題というほどではないのですが以前使っていたバージョン(0.8.2)からブラウザ変更の際に現在のバージョン(0.9.1)をインストールしなおした結果タイムスタンプ一覧が別ウインドウとしてポップアップするようになってしまいました前のように同ウインドウで見られる方が便利だったのですが設定等で変えられることは可能なのでしょうか？現在は以前使っていたバージョンを読み込み直し使っています

長時間のアーカイブを見るのに必須級のツールです。タイムスタンプ表示系のツールは色々試しました。「Highlights for YouTube」「youtube timestamp loader」などなど数あるツールの中で、複数の投稿されるタイムスタンプを自動的に統合し、時間順に並べ、全体の流れを把握しやすくしてくれるツールは本ツールを置いてほかにありません 2021-08-05現在、正常に動作します YOUTUBE APIに対応したおかげで、YOUTUBEの仕様変更に怯えずすむようになりました

入れてみましたが機能しません。おそらくYouTubeの仕様変更が原因でしょうか？追記なんやかんやあって使えるようになって、今まで快適に使わせていただいていましたが、唐突に利用できなくなりました。具体的な症状は、アイコンをクリックした際読み込みがいつまでも終わらず、タイムスタンプが表示されないというものです(俗にいう無限ロード？)。もちろん、動画にはタイムスタンプが張られていることは確認済みです。シークレットウィンドウで拡張機能が少ない状態でも検証してみたので、他の拡張機能との競合では無いようです。拡張機能の管理ページに行ってみると、エラーが出ていましたが、関係があるかは分かりません。とても使いやすく気に入っている拡張機能なので、もし可能なのであれば修正していただけると幸いです。

タイムスタンプとコメントの文字サイズをそれぞれ調整できるようにして欲しい。タイムスタンプを含んだ長文コメントを読み込むとスクロールが長くなるので

60分を超える指定 1:01:01などの時1:01として認識されてしまう ↑修正されたみたいです！あとは１コメントに複数タイムスタンプがある場合に重複表示してしまうのが気になります

Tem mais Bug que a selva amazônica, mas a ideia é muito boa.

Display timestamp comments on YouTube videos

Helps users find and navigate to specific timestamps mentioned in YouTube video comments, making it easier to jump to relevant parts of a video based on comment timestamps.

1. User installs extension and obtains a YouTube Data API key from Google Cloud Console. 2. User stores the API key in the extension's storage (via chrome.storage.sync). 3. When viewing a YouTube video page (youtube.com/watch*), the extension fetches comments for that video using the YouTube Data API. 4. It parses comments for timestamp patterns (e.g., 1:23, 01:23:45). 5. The extension displays these timestamp comments in a popup panel, sorted by time. 6. Clicking a timestamp jumps the YouTube video playback to that position.

Target users: YouTube viewers who want to quickly find specific moments in videos based on comment timestamps / Users watching long-form YouTube content with timestamped discussions in comments

The pageAction.js file is heavily minified (~1MB), making it difficult to fully trace all UI interactions. However, the core logic in contentScript.js and background.js is clear. The extension requires a user-provided YouTube Data API key, which is a free tier from Google Cloud, not a paid feature of the extension itself. The extension does not handle API key provisioning or billing.

Monetization

No paid features detected

The extension is free. It requires a YouTube Data API key (user-provided, not managed by the extension vendor). The extension itself does not gate any features behind a paywall, subscription, or license check. The 'license' keyword matches in the source are from Font Awesome and React open-source licenses, not paid feature gating. There is no payment platform integration, no subscription UI, and no upgrade prompts.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension does not implement any login mechanism. It requires the user to be on a YouTube video page (destination_service is YouTube, which may require login for some features, but the extension itself does not gate its core workflow behind an extension-level or destination-service-level account creation/login flow specific to this tool. The extension uses a user-provided YouTube Data API key stored in chrome.storage.sync. If no key is provided, it shows an error. There is no sign-in UI, OAuth flow, or account creation in the extension code.
