The transcription tool that understands Bilibili's unique format
Bilibili isn't just another video site — it has multi-part videos (P1, P2, P3...), dense educational content, and audiences speaking Mandarin, Cantonese, Sichuan dialect, and dozens of other languages. Vocova handles all of it. Paste any BV or AV link and get an accurate, timestamped transcript. Note: danmaku (scrolling comments) are viewer-generated overlays and are not included in the transcript — only the video's spoken audio is captured.

Features
Multi-part video support
Bilibili's P1/P2/P3 multi-part format is unique to the platform. Select a specific part to transcribe, so you get exactly the section you need without processing the entire series.
Chinese dialect handling
Bilibili content spans Mandarin, Cantonese, Sichuan dialect, and other regional varieties. Vocova detects and transcribes each dialect accurately, not just standard Mandarin.
Academic content density
Bilibili is a hub for educational content — university lectures, technical tutorials, and science explainers. Vocova handles the specialized vocabulary and dense information delivery common in these videos.
BV and AV URL formats
Whether you copy a modern BV-format URL or an older AV-format link, both are recognized and processed. Just paste whatever URL your browser shows.
100+ languages beyond Chinese
Bilibili hosts international content too. Japanese, English, Korean, and other languages are auto-detected and transcribed alongside Chinese-language videos.
Why choose Vocova
Turn educational videos into study notes
Bilibili's educational content is some of the best on the internet. Convert lectures and tutorials into text you can annotate, highlight, and review.
Search within video content
Video audio is unsearchable. With a transcript, you can instantly find specific explanations, formulas, or references across hours of educational content.
Create subtitles for cross-platform sharing
Export SRT or VTT files to add subtitles when sharing Bilibili content on other platforms, improving accessibility and reach.
Preserve dialect content in text
Regional dialect content on Bilibili captures cultural perspectives that standard Mandarin doesn't. Transcripts preserve this spoken content in a referenceable format.
