About this app

Turn raw footage into polished, ready-to-share video in one focused mobile studio.

Captionist combines AI captions, multilingual translation, natural dubbing and hands-on editing, so you can move from import to export without juggling separate apps.

Caption with confidence

• Generate timed captions from your video's audio
• Edit caption text, timing, position and appearance
• Apply creator-ready caption styles and templates
• Preserve Arabic, Persian and other complex scripts correctly

Translate and dub

• Translate caption tracks into supported languages
• Generate AI voiceovers from your captions
• Choose a voice and add delivery notes
• Keep caption and dub timing aligned with your video

Edit in one workflow

• Trim, split and crop video
• Add overlays and work with video and audio controls
• Adjust color, filters, speed and volume
• Fine-tune captions and sound from the same timeline
• Undo and redo changes while you create

Export for every platform

Choose layouts for Reels, TikTok, Instagram and YouTube, then export at the quality your project needs. Resolution options include 720p, 1080p, 1440p and 4K when supported by your source video and device.

Made for multilingual creators

Captionist is designed for global scripts, including right-to-left text. Arabic and Persian shaping, punctuation, numbers and bidirectional layout are treated as core editing requirements, not afterthoughts.

Private by design

Projects and source videos remain on your device. When you choose a cloud AI feature, the content needed for that request, such as extracted audio or caption text, is sent securely to service providers for processing. Account and data deletion controls are available in the app.

Whether you create short-form social video, product stories, tutorials or multilingual content, Captionist gives you a refined studio that travels with you
