TubeScribeAI

TubeScribeAI is a free YouTube transcript and productivity toolkit, available as a website and a Chrome extension, built for anyone who needs to pull information out of a YouTube video faster than watching it start to finish.

At its core, TubeScribeAI extracts the available captions from any YouTube video into a clean, readable transcript, downloadable as TXT, SRT, or VTT. AI-powered tools take it further: generate a video summary that adapts to the actual content, create timestamped chapters ready to paste into a description, or translate subtitles into another language while keeping original timestamps intact.

The Chrome extension brings this straight onto the YouTube watch page: a transcript panel with clickable, playback-synced timestamps below the video, so you can search, copy, export, summarize, or translate without leaving YouTube.

Beyond transcripts, TubeScribeAI includes creator and SEO tools: thumbnail downloader (5 resolutions up to 1280x720), tag extractor for competitor research, timestamp link generator, embed code generator, chapter formatter, character counter, video ID extractor, thumbnail safe-area preview, aspect ratio calculator, and keyword density checker.

A set of subtitle converters rounds it out: SRT to VTT, VTT to SRT, SRT to plain text, SBV to SRT/VTT, and a subtitle time-shifter for out-of-sync captions.

Everything works without an account or watermark, free within fair-use limits. It relies on YouTube's own caption tracks (manual or auto-generated), so it works on any video with existing subtitles.

Useful for students reviewing lectures, researchers and journalists pulling quotes from interviews, creators building chapters and captions, language learners, and SEO professionals researching competitor tags.
