Timed like a human captioner, at machine speed

Most caption tools estimate timing from sentence boundaries. The subtitle agent aligns every word to the audio waveform itself, so highlights land exactly when the word is spoken — even through crosstalk, music beds, and fast cuts.

  • Word-level timestamps aligned to the waveform, accurate to ±50 ms
  • Karaoke, pop-in, and clean-line animation styles
  • Active-word highlight with per-word color and scale control
  • Safe-zone aware placement for 9:16, 1:1, and 16:9

Your brand, on every caption

Set your fonts, colors, stroke, and position once. The memory agent stores it as your house style, applies it to every project, and lets you restyle an entire video in one click — no re-render of the underlying edit.

  • Brand fonts, colors, and outline saved as named presets
  • Memory recalls your caption style across projects
  • Keyword and emoji emphasis only where it earns attention
  • One-click restyle without touching the cut

How AI Captions works

  1. 1

    Upload anything

    Drop in a video and the transcription agent returns a word-level transcript with speaker labels — about a minute of processing per hour of footage.

  2. 2

    Pick a style

    Karaoke highlight, word-by-word pop, or clean lines. Fonts, colors, and position come from your brand kit — or from memory of your last project.

  3. 3

    Review and render

    Every word is editable on the timeline. Correct a name once and custom vocabulary spells it right on every future upload.
