How do I make a viral short with CaptionBolt?

Upload a video or paste a YouTube link. CaptionBolt helps find strong moments, add captions from 301 styles, crop to 9:16 vertical, and translate when needed. Preview, tweak, and export.

Can I turn a podcast or long interview into multiple shorts?

Yes. Drop in up to 60 minutes. CaptionBolt finds promising moments, scores each clip, and prepares 9:16 shorts with captions and face tracking applied.

What makes CaptionBolt different?

CaptionBolt is built end-to-end for short-form creators: 301 caption styles, speaker-tracked vertical cropping that switches layouts mid-conversation, ranked clip drafts from your long videos, and AI dubbing in 30+ languages. Pricing stays creator-friendly, and new accounts get 10 free minutes of dubbing.

How accurate are the AI captions?

CaptionBolt creates word-level timing across 30+ languages with auto-language detection. You can click any word to fix transcription errors, and the preview updates instantly.

How does AI Dubbing work, and what's the free credit?

Upload a video, pick a target language. AI Dubbing renders the new language with a natural-sounding voiceover, and captions stay aligned to the new audio. On signup, you get 10 minutes of dubbing free. No card, one-time. After that, dubbing minutes count against your plan.

What do I get on the free plan?

10 minutes of video per month, 3 minutes per video max, five basic caption styles (you can preview all 301), MP4 export with a small CaptionBolt watermark, and plain-text export. AI Viral Clips and dubbing require a paid plan.

Can I cancel or get a refund?

Cancel anytime from settings. No call, no email hoops. Full refund within 14 days of purchase if CaptionBolt isn't the right fit, no questions asked.

AI Reframe

Cropped for TikTok and Instagram. Speaker stays in frame.

Not a center crop. AI locks onto the speaker, follows faces frame by frame, and switches layouts when the scene changes.

Single-focus
One person talking? The camera zooms in and tracks the face.
Split-screen
Two people in dialogue? Stack them vertically so both stay visible.
Group-wide
Multiple speakers? Pull wide so nobody gets cut off.
