Transcript history

Loading history…

    When captions are unavailable, audio is transcribed by Whisper through OpenRouter. Transcript text is sent to MiniMax for paragraph formatting and light corrections, plus translation or a summary if selected.

    Speech recognition can make mistakes. Check against the original video. Signed-in transcripts are saved to your account; guest transcripts stay in this browser. Temporary task files are removed after 6 hours; saved history remains.

    One task at a time. Busy periods may mean a queue or a usage limit. Please only process content you have the right to use.

    Getting the Bilibili video link

    Copy the video page URL from your browser, or use Share → Copy link in the Bilibili app. Both BV video URLs and b23.tv short links work. You can paste the whole shared message.

    Select Get subtitles after pasting the link. To find a particular explanation in a long video, search the transcript for a phrase and use the timestamps to locate that passage.

    Common questions

    What if the video has no CC subtitles?

    The tool transcribes the audio when it cannot retrieve captions. The video must be accessible and contain understandable speech. Check names, technical terms and numbers against the recording.

    Are danmaku comments included?

    No. The transcript comes from captions or speech. Scrolling comments and unspoken text on screen are not included.

    Is it free? Do I need an account?

    It is free to use without an account. Each network or browser can submit up to 20 videos in 24 hours, one at a time. You may need to wait when the queue is busy.

    How long are results available?

    Results are available for 6 hours in the browser you used to submit the link. Copy the text or download the files you want to keep.
