Download as SRT, TXT, or PDF. AI-powered transcription for videos without captions. ## Overview BibiGPT's Bilibili Subtitle Downloader lets you extract complete subtitles from any Bilibili video by simply pasting the video link. Export in three formats: SRT (with timestamps), plain text TXT, and formatted PDF. For videos without official subtitles, the system automatically uses AI speech-to-text transcription to generate them. ## Pain Point Many high-quality educational, finance, and tech videos on Bilibili lack subtitles, or their subtitles can't be copied directly. Taking notes, repurposing content, or translating to other languages requires painstaking manual transcription — extremely inefficient. BibiGPT solves this: paste the link, extract instantly, export in your preferred format. ## Key Features * Supports all standard Bilibili video URLs: BV, AV, mobile links, and playlist URLs * Three export formats: SRT (with timestamps), plain TXT, formatted PDF * AI transcription for videos without official subtitles * Full support for multi-part (multi-P) videos * Fast extraction, typically completed in seconds ## Use Cases * **Study Notes**: Extract key points from educational videos without rewatching — read the text version directly * **Content Repurposing**: Turn Bilibili video scripts into blog posts, articles, or social media content * **Subtitle Download**: Export SRT files for video translation, subtitle burning, or offline archiving ## Tips * Use the full Bilibili video URL (with BV number) for best compatibility * For multi-part videos, include the `?p=` parameter in the URL; otherwise it defaults to the first part * AI transcription works best for Mandarin; strong dialects may require manual review * After extraction, use BibiGPT's AI summary feature to further distill key insights *** **Related Feature**: [AI Bilibili Video Summary](https://bibigpt.co/features/ai-bilibili-summary) — Try it now **Upgrade to Pro**: Unlock unlimited usage → [View Pricing](https://bibigpt.co/pricing) ## Related Features
