CaptioAI Subtitle Creator

Auto generated subtitles for your videos using AI, right on your phone.

CaptioAI is a mobile app that automatically generates subtitles for your videos using artificial intelligence. It transcribes spoken audio into text, allows easy editing and customization, and lets you export the final result — all directly on your device, with no internet required.

CaptioAI includes a built-in speech recognition system that processes audio quickly and accurately. Because all processing happens on your phone, your data stays private and the app works even without a network connection.

Once a video is transcribed, you can review the subtitles and make manual adjustments if needed. The interface is designed to make editing simple and intuitive, even for longer clips.

To help match the style of your content, CaptioAI allows you to customize how subtitles appear. You can change the font, size, color, and position of the text before exporting the final video.

CaptioAI is designed to be fast, lightweight, and easy to use, giving you full control over your subtitles without relying on cloud-based tools or external services.
