Bidi Captions

AI story video generator and captions editor, in your browser

Bidi Captions has two tools that run on your own device: no API key, no credits and no uploads.

AI story video generator

  • Type a topic and pick a viral format: "What if...", "What it looks like in every level of [a job]" or "What it looks like to marry into [a rich family]".
  • It writes the script in English, narrates it in one of 9 voices and shows a new picture every 10 to 20 seconds, with a slow pan and zoom.
  • Long videos of 10 to 30 minutes for YouTube and Spotify video podcasts, with the captions burned in.
  • Vertical shorts of under a minute that end on a "Follow for part 2" banner.
  • A ready-to-paste description for every video, with chapters and hashtags.

Captions editor

  • Auto-captions for speech in 99 languages, highlighted word by word.
  • Right-to-left done right for Hebrew, Arabic, Persian and Urdu: no reversed words or stray punctuation, even with English words in the line.
  • Export an MP4 with the captions burned in, or SRT and VTT subtitles.

Plans

  • Free, no account: auto-captions, right-to-left fixes, unlimited SRT and VTT export, and one story short of up to 60 seconds. Video exports carry a small watermark and stop at 60 seconds.
