Captionist: AI Video Studio

Caption videos that read naturally in every language. Translate, style, dub, and export polished social videos from one private, mobile-first studio.

Turn raw footage into polished captioned videos—from your phone.

Captionist is an AI video studio for creators who want accurate captions, fast editing, natural translation, and optional AI dubbing without moving an entire project into the cloud.

CAPTIONS THAT READ RIGHT • Automatically transcribe speech into editable captions • Fine-tune caption timing and edit individual words • Style type, color, position, and templates • Render Arabic, Persian, Urdu, and other complex scripts with correct joining and mixed-direction text

CREATE FOR EVERY AUDIENCE • Translate captions while preserving the source timing • Generate dubbed audio with a choice of studio voices • Record voiceovers and, with explicit consent, create a reusable voice • Add dubbing minutes when you need more

EDIT AND EXPORT • Crop, resize, adjust, filter, and arrange clips • Preview captions directly on your video • Export watermark-free HD or 4K video with eligible plans • Keep source videos and projects on your device; only the audio or text needed for the AI feature you request is securely sent for processing
