Word-level timing
Each word appears as it is spoken, the caption style short-form viewers expect and feeds reward.
AI Captions Generator
Word-accurate animated captions generated straight from your audio, styled for short-form video and rendered into the final clip.
Workflow
How it works
Add your video
Upload a clip or use one produced inside GPT-Video. The audio is transcribed with Whisper-class speech recognition.
Review the transcript
Captions are generated word by word with precise timings. Fix a name or a term once and the captions update everywhere.
Style and render
Pick the caption look, and the animated text is rendered into the exported vertical video — no separate subtitle file to manage.
Why it matters
What you get
Sound-off friendly
Most feeds start muted. Burned-in captions make your clip watchable from the first silent second.
Part of the pipeline
Clips from the AI clip generator, stream highlights and story formats all pass through the same captioning engine automatically.
Editable before export
Correct the transcript, change the style, or ask the vibe editing agent to restyle the captions in plain language.
FAQ
How accurate are the AI captions?
Transcription uses Whisper-class speech recognition, which is highly accurate on clear speech. You can review and correct the transcript before rendering.
Are the captions animated?
Yes — captions appear word by word in sync with the audio, in styles designed for TikTok, Reels and Shorts.
Do I get a subtitle file or burned-in captions?
Captions are rendered into the exported video, so they display identically on every platform with nothing extra to upload.
Is captioning automatic for generated clips?
Yes. Clips produced by the clip generator and the viral formats come out captioned by default.
