About this app

CaptionLab turns any video into captioned, subtitled content in seconds — powered by AI that understands what's actually being said, not just raw speech-to-text.

WHAT YOU CAN DO
• Auto-generate accurate captions from any video
• Translate captions into 40+ languages
• Edit, restyle, and fine-tune every line
• Export as SRT or VTT, copy as text, or burn captions straight into your video
• Built for creators who post everywhere: Reels, TikTok, Shorts, YouTube, podcasts, courses, and ads

HOW IT WORKS
Import a clip, pick a language, and CaptionLab transcribes, understands the context, and produces perfectly timed captions you can style and export.

CaptionLab Pro (auto-renewable subscription) unlocks unlimited captions, 40+ language translation, premium styles, and burned-in video export. Subscriptions are billed weekly, monthly, or yearly and renew automatically unless cancelled.

What’s new
