  • Free generation + free editing
  • 1080p MP4 with captions burned in
  • .ass subtitle download included
Generate, edit, and preview unlimited captions for free. Pay only when you export.

The shift

Stop wasting hours on captions you’ll redo anyway.

Here’s the difference between editing the old way and the CapzAi way.

The old way

Painful
  • 2–4 hours hand-typing captions per video.
  • Pay $20+ per minute for an editor — every time.
  • No control over timing, styling, or export quality.
  • One language at a time. RTL is a nightmare.
  • Rebuild your style from scratch on every clip.
  • Final file looks generic. Watch time drops.

The CapzAi way

Recommended
  • Captions ready in under a minute. Edit only what matters.
  • Pay only when you render. Generation and edits stay free.
  • Word-level timing, color, font, layout — fully yours.
  • Arabic, Darija, French, English — switch in one click.
  • Save a preset once, reuse it across every video.
  • Burn-in 1080p MP4 ready to ship to TikTok, Reels, Shorts.

How it works

From raw clip to viral-ready MP4 in 3 steps.

No tutorials. No prompts. A real editor that respects your workflow.

01

Drop your video.

Drag a short-form clip into CapzAi. We keep the original audio, framing, and pacing untouched.

≈ 10 seconds
02

Tune every word.

AI generates word-level timing. Fix wording, slide timing, restyle — preview live on the video.

≈ 2 minutes
03

Export and post.

One click renders a 1080p MP4 with captions burned in, ready to ship to TikTok, Reels, or Shorts.

≈ 1 minute
You pay only for final renders. 20 credits per started minute. A 61-second video = 40 credits. Generation and editing are always free.

Real results

Creators who switched aren’t going back.

From solo creators to in-house teams — here’s what changed when they ditched the old way.

5x faster turnaround

I went from 2 hours per video to 20 minutes. The word-level editor is the difference. I edit only what the AI gets wrong — which is barely anything.

We were paying an editor $20/min just for captions. Now my team handles 80 videos a month in-house with predictable credits. Total no-brainer.
