Export Bilibili CC subtitles as SRT, VTT, or TXT — timestamps kept, danmaku left out. Paste a bilibili.com link, a BV number, or a b23.tv share link; most Bilibili videos carry no CC track at all, so BibiGPT transcribes the Mandarin audio with AI when needed. Free, no login, no Bilibili account required.
Paste a Bilibili URL — get SRT or VTT in seconds. The live BibiGPT app loads inline; no redirect, no tab switching.
Paste a Bilibili link (bilibili.com URL, BV number, or b23.tv share link) into BibiGPT and export .srt, .vtt, or .txt with timestamps kept. If the video has an official CC track, it is extracted verbatim; most Bilibili videos have none — danmaku is not a transcript — so BibiGPT transcribes the spoken audio and still returns a clean file. No Bilibili login or 大会员 needed.
Most subtitle downloaders fail the moment a Bilibili video has no captions. BibiGPT auto-transcribes with AI when needed, so you always walk away with a clean SRT, VTT, or TXT file.
BibiGPT first pulls the creator-uploaded or Bilibili auto-captions verbatim. If the video has none, it transcribes the spoken audio with AI so you still get the full text.
SRT and VTT keep timestamps so you can re-burn subtitles into an edit. TXT is plain copy-ready text. Markdown drops straight into Obsidian or Notion.
Paste a bilibili.com or b23.tv share link — both work out of the box. Same one-click flow, same export formats every time.
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.
Once captions are extracted, translate to Chinese, English, Japanese, Korean, or Traditional Chinese — and download a bilingual SRT.
Skip watching: get a structured summary plus visual mind map of the Bilibili content. Great for research and content briefs.
Free users get 3 caption extractions per day. Plus ($19.8/mo) raises to 50/day, Pro ($34.8/mo) is unlimited with batch API.
No signup needed for the free tier. Use the embedded tool above — your URL is processed in seconds.
Copy the share link from Bilibili — bilibili.com URLs, BV numbers, and b23.tv short links from the mobile app all work out of the box.
If the video carries an official CC subtitle track, BibiGPT extracts it verbatim. If not — the common case on Bilibili — it transcribes the Mandarin (or other) audio via AI, typically 5-15 seconds for a short clip.
SRT (timestamps for re-burn), TXT (plain text), Markdown (Notion ready), or copy to clipboard. What you get is the spoken script — danmaku overlay comments are not mixed in.
How the commonly cited subtitle tools actually behave on Bilibili links. Capabilities below reflect each tool's own documentation and issue tracker.
| Capability | BibiGPT | yt-dlp | NoteGPT | DownSub |
|---|---|---|---|---|
| Bilibili link support | bilibili.com / BV number / b23.tv, no login needed | Supported via its Bilibili extractor; CC access can require passing browser cookies | Bilibili summarizer accepts video URLs | Not supported — Bilibili is not in its site list (YouTube, Viki, Viu…) |
| Videos without CC subtitles | AI transcribes the audio automatically — works on the majority of Bilibili videos | Nothing to download — it only fetches existing tracks, and often returns danmaku XML instead of captions | Generates a transcript as part of its AI summary flow | Nothing — needs an existing subtitle track |
| Timestamped subtitle file export | SRT / VTT / TXT / Markdown | Native subtitle formats when a real CC track exists | Geared to notes — exports summaries/transcripts as PDF or Word, not SRT | SRT / VTT / TXT (on supported sites only) |
| Danmaku vs subtitles | Extracts the spoken script; danmaku is excluded | Danmaku downloads as XML; turning it into ASS needs a plugin — and it's still comments, not a transcript | Not a danmaku tool | N/A |
| Setup | None — paste a link in the browser | Command line install + per-site flags and cookies | Web tool, freemium quota | Web tool with ads |
Built around what people actually do with Bilibili's Chinese-first catalog — study content, translation, and research.
Bilibili's knowledge zone is full of full-length courses and tech talks that never ship a CC track. Extract the transcript, export Markdown into Notion or Obsidian, and search the lecture instead of scrubbing through it.
Pull the Mandarin script from a trending Bilibili video, get a timestamped SRT, and translate it for YouTube or other platforms. BibiGPT's one-click translation produces a bilingual SRT ready for re-burn.
Vlogs and interviews on Bilibili are natural listening material. Download the transcript, line it up against the audio by timestamp, and build Anki decks from real colloquial Mandarin instead of textbook dialogs.
Platform announcements and format standards this page relies on.
Bilibili's own AI-generated smart captions (智能字幕) exist but are off by default and cover only part of the catalog — which is why most videos still play with danmaku only.
Bilibili 专栏 — 智能字幕上线公告 ↗SRT (SubRip) files are numbered cues with start/end timestamps followed by the subtitle text — the structure BibiGPT preserves on export.
Matroska.org — Subtitle format specifications ↗WebVTT (.vtt) is the W3C standard for timed text tracks on the web — the caption format used by HTML5 video players.
W3C — WebVTT: The Web Video Text Tracks Format ↗A Bilibili subtitle downloader is a tool that turns a Bilibili video into a timestamped subtitle file you can save. It reads the official CC track when the uploader attached one; when there is none — the usual case — it transcribes the spoken audio. BibiGPT exports SRT, VTT, TXT, or Markdown and does not mix danmaku comments into the file.
Danmaku (弹幕) are viewer comments that scroll across the video. They are not a transcript of what is said. Bilibili subtitles are the optional CC track an uploader attaches, and most videos do not have one. A subtitle downloader must transcribe speech; downloading danmaku XML still leaves you with comments, not a script.
Yes. CC subtitles are opt-in for Bilibili uploaders, and the platform's own smart captions are off by default. Paste the link anyway: BibiGPT transcribes the audio and returns a timestamped SRT, VTT, or TXT. Accuracy is typically above 90 percent on everyday Mandarin when speech is clear.
