Captions AI

What is Captions AI?

Captions AI is an AI-driven video editing app that works entirely mobile and cloud-based, designed for content creators on social media. The core of the tool is automatic captioning: you upload a video and within seconds accurately timed, styled subtitles are burned into the footage, with no manual work. Around that, the app offers a complete suite of smart editing features specifically tuned to the speed that short-form video demands.

How does Captions AI work?

The captioning runs on a proprietary ASR model (Automatic Speech Recognition) optimized for short videos and colloquial language, so casual speech and slang are recognized well. The silence detector analyzes energy levels and speech activation to automatically cut out pauses above an adjustable threshold, noticeably improving a video's pacing.

The eye contact correction analyzes eye position per frame and, using facial landmark detection and synthesis, adjusts the pupil direction so you appear to be looking at the camera, even when reading a script off a screen. Everything runs in the cloud, so heavy editing doesn't have to happen on your own device.

Key features

• Automatic captioning — accurately timed, styled captions burned directly into the video.
• Eye contact correction — corrects your gaze so you look straight at the viewer.
• Silence removal — automatically cuts out pauses for a tighter pace.
• AI B-roll suggestions — proposals for supplementary footage that strengthens your story.
• Clip generator — splits longer videos into short clips for TikTok, Reels and Shorts.

Captions AI compared with alternatives

Unlike desktop editors such as Premiere Pro or CapCut, Captions AI is fully mobile and cloud-based, with a workflow built for speed. Where standalone captioning tools like Rev or Kapwing focus on a single task, Captions AI combines captioning with a broader palette of video features in one app. The eye contact correction is also a feature that direct competitors rarely offer at comparable quality.

Who is it for?

Captions AI is intended for YouTubers, TikTokers, Instagram Reels creators and podcasters who publish video regularly. Because many viewers watch videos without sound, subtitles are essential; where doing that manually quickly takes an hour for a ten-minute video, with Captions AI it is reduced to a few minutes of editing.
