Frequently Asked Questions

What is YouTube Timestamp?expand_more

YouTube Timestamp is a Chrome extension that saves exact moments in YouTube videos with notes and tags. Keep them in a searchable local library, and use the workspace beside the video to read transcripts, generate AI summaries, and ask questions about the video.

What can I use for free?expand_more

Save unlimited local bookmarks and notes, add tags, search your library, and jump back using timestamps or timeline markers. JSON backup and restore are also free. You can keep reading saved transcripts, summaries, and conversations after your trial ends.

Do I need an account?expand_more

You do not need a YouTube Timestamp account to save notes, start the trial, or activate a lifetime license. AI features use an API key from your chosen provider. A purchase email is required so your license key can be delivered and recovered.

How does the 14-day Pro trial work?expand_more

Choose Start free trial in extension Settings when you are ready. Installing the extension does not start the trial. You get 14 days of folders, caption capture, transcript import, AI summaries, and video chat, with no account or card required. AI provider usage is billed separately. After expiry, free features keep working and saved content remains readable and exportable.

What does the lifetime license include?expand_more

The founding price is $5 as a one-time payment, with no license expiry or recurring license payment. It unlocks video folders, caption capture, transcript import, AI summaries, and video chat on one active browser installation at a time. Your license key is emailed after purchase. Activate it in Workspace or Library Settings → Lifetime license. AI credits are not included.

Can I move my license to another device?expand_more

Yes. Deactivate the license on the old installation, then activate it on the new one. If you cannot access the old installation, use Recover license / manage devices in Settings. Export and restore a JSON backup to move your library too; moving the license does not transfer your saved content.

How do AI summaries and video chat work?expand_more

During your trial or with Pro, add your Gemini, OpenRouter, OpenAI, or DeepSeek API key in Settings. Capture available captions or import a transcript, then generate a summary or ask questions about that video. Requests go to your chosen provider, which bills API usage separately. Provider, model, and transcript-size limits apply.

What if a video has no captions?expand_more

Caption capture depends on what YouTube makes available and may fail for some videos. During your trial or with Pro, you can import plain or timestamped text, SRT, or WebVTT as a fallback. Summaries and video chat need a transcript. Timestamped bookmarks and notes work without one.

Where is my data stored?expand_more

Your local library is stored in your Chrome profile and is not automatically synced across devices. When you request an AI summary or chat answer, the transcript, question, and relevant context go to your chosen provider. Its privacy and retention policies apply. License activation and periodic checks contact Dodo Payments.

Can I back up and restore my library?expand_more

Yes. Export your local library as JSON and restore it through the extension's import controls. Backup and restore are free. Keep a backup before changing devices, removing a Chrome profile, or uninstalling the extension; your library is not automatically backed up. API keys and license activation records are excluded from library backups.

Does it work on mobile or offline?expand_more

The extension is designed for desktop Chrome. Your local library is not available in a mobile browser. Saved content can be read offline, but new AI requests and caption capture need internet access. A lifetime license also needs internet access for activation and periodic checks, with up to 14 days of offline Pro access after a successful check.
