Captions finished in the browser

AutoCaptions turns speech into timed captions you can edit, style and export — without a desktop editor or a render queue. It is built and operated by an independent team.

Why we built it

Most caption tools force a choice: a full video editor that treats captions as an afterthought, or a transcription tool that stops at a wall of text. We wanted the shorter path — drop a clip, get timed captions, fix the words that matter, choose a look, and export a file you can post.

The product is deliberately narrow. It does not try to be a timeline editor, a stock library, or a social scheduler. It focuses on the caption layer: transcription, timing, readability, styling and export.

What we believe

  • Your video is not our content. The video is read in your browser. Only the extracted audio is sent for transcription. We do not keep a video caption history.
  • Free should be usable. The free plan includes the full editor and free SRT/VTT/TXT downloads. Video exports carry a watermark and are capped at 720p and 10 minutes; the limits are stated before you start.
  • No fake accuracy numbers. Transcription quality depends on the audio. We do not claim a universal “99% accurate” figure; we explain what affects accuracy and why you should review captions before publishing.
  • Boring is good for billing. Paddle is the Merchant of Record. You get a receipt, a customer portal, and a clear cancellation path. We do not store card numbers.

How the product works

  1. You choose a video in the browser. The audio track is extracted locally.
  2. The audio is sent to our transcription provider and returned as timed words and captions.
  3. You edit wording, merge or split lines, adjust timing, translate, and apply a style.
  4. You export a captioned MP4, or download SRT/VTT/TXT. Subtitle files are free on every plan.
