Vidleaf

Vidleaf is a research tool that searches video captions, verify the moment, export cited quotes. Vidleaf reads YouTube and Bilibili captions, lets users search within them, check each passage against the original video, and export selected quotes as Markdown, TXT or SRT with timestamps and source details.

Vidleaf is a transcript reader built around one job: helping people find the exact words in a long video and carry them into notes with the source attached. A user pastes a YouTube or Bilibili link, and the tool loads the existing captions, showing the caption language and where those captions came from so the reader can judge their reliability before relying on them. From there the workflow is search-first. Typing a phrase highlights matching caption rows while keeping the neighbouring lines visible, so a quote can be read in context rather than as an isolated fragment. Each line carries a timestamp that links to the original video at that moment, which makes it quick to confirm what was actually said. Selected rows can be exported as Markdown or plain text, or as an SRT subtitle file. The Markdown export keeps the original wording, the caption source, time ranges, and attribution and license details where they apply, which suits researchers, students, journalists and writers who need to cite carefully. Beyond existing captions, Vidleaf handles recordings that have none. Signed-in users can upload audio, or extract sound from a video, and confirm transcription after reviewing their allowance and a processing notice. Uploads stay in the user's account, and uploading alone does not start a job. An interview feature separates voices so a transcript can be filtered to one speaker, using names supplied by the user rather than inferred from voices. Optional AI summaries and translations exist, with a clear warning that they should be checked against the original. The pricing model separates cheap reading from metered processing. Reading existing captions is free, with a daily guest limit and no limit for registered accounts, while transcription and AI tasks use weekly allowances plus an optional one-time minute pack. Compared with general transcription services or summarizers, Vidleaf is narrower and more citation-minded: it favours verification and quoting over automatic digests, and it keeps the page free of ads.
