FAQ

Questions, answered.

How do I download a YouTube transcript?

Install ScriptSnap from the Chrome Web Store, open any YouTube video, and click Download under the video title. Pick TXT, SRT, VTT, Markdown, CSV or JSON and the file saves to your computer.

Can I copy a YouTube transcript with timestamps?

Yes. Click Copy under the video to copy the full transcript with timestamps like [2:15]. You can switch timestamps off in settings to copy plain text instead.

Is ScriptSnap free?

Yes. ScriptSnap is free, with no account, no daily limits and no ads.

Does it work on videos without captions?

ScriptSnap reads the captions YouTube already has, including auto-generated ones. If a video has no captions at all, there is no transcript to copy.

Can I download YouTube subtitles as an SRT file?

Yes. Choose Subtitles (SRT) from the Download menu. You get a standard .srt file with numbered cues and start and end times, ready for video editors and media players.

Does ScriptSnap collect my data?

No. Everything runs in your browser. ScriptSnap has no servers, no analytics and no account, and it only asks for one permission: storage, to remember your settings.

Can ScriptSnap summarize a video with AI?

ScriptSnap builds a ready-made prompt for a summary, study notes, a blog post or a thread, copies it with the transcript, and opens ChatGPT, Claude or Gemini so you can paste it in. It never sends anything on its own.

Which languages are supported?

Any language the video has captions in. You can switch between caption tracks, and use auto-translate when YouTube offers it for that video.
