Features

Why this beats DownSub or browser extensions

Most caption downloaders fail when the video has no native captions. BibiGPT auto-transcribes via AI when needed, so you always get text — for any YouTube video.

Captions when they exist, AI transcript when they don't

BibiGPT first tries to extract creator-uploaded or YouTube auto-captions. If the video has none, it transcribes the audio with Whisper + Gemini hybrid pipeline.

SRT + TXT + Markdown export

SRT preserves timestamps so you can burn the subtitles back into a re-edit. TXT is plain text for paste-ready notes. Markdown is Obsidian / Notion friendly.

Works across long-form videos, Shorts, livestream replays

youtube.com / youtu.be URLs both work. Same flow, same export formats.

What you get on top of just the captions

If you only need raw captions, that's one click. If you want more, BibiGPT layers translation, summary, and AI dialog without leaving the page.

One-click translate to 5 languages

Once captions are extracted, translate to Chinese, English, Japanese, Korean, or Traditional Chinese — and download a bilingual SRT.

AI summary and mind map

Skip watching: get a structured summary plus visual mind map of the YouTube content. Great for research and content briefs.

Free for daily use

Free users get 3 caption extractions per day. Plus ($5.9/mo) raises to 50/day, Pro ($15/mo) is unlimited with batch API.

3 steps to finish

No signup needed for the free tier. Use the embedded tool above — your URL is processed in seconds.

  1. 1

    Paste YouTube URL

    Copy the share URL from YouTube. The widget supports youtube.com or youtu.be out of the box.

  2. 2

    Wait a few seconds

    If the video has native captions BibiGPT extracts them verbatim. If not, it transcribes the audio via AI — typically 5-15 seconds for a short clip.

  3. 3

    Download or copy

    SRT (timestamps for re-burn), TXT (plain text), Markdown (Notion ready), or copy to clipboard.

3 typical scenarios

Built for content creators, language learners, and anyone who wants a YouTube's text without watching.

Content creators — repurpose / re-dub

Pull captions from a viral YouTube video, translate, re-dub for Bilibili / Douyin / YouTube Shorts. Cuts hours of manual transcription per video.

Language learners — dual-language notes

Download English YouTube captions, paste into Anki / Notion. BibiGPT can auto-translate to Chinese / Japanese for side-by-side study notes.

Researchers — citation-grade transcripts

Export full transcripts of public YouTube statements for citations or fact-checks. Timestamped SRT lets you reference specific moments.
