SubTitler - Auto Captions

SubTitler helps add burned-in captions to one selected video.

Choose a video and SubTitler transcribes the audio on iPhone, places readable captions on the video, and saves a new MP4 while leaving the original untouched.

Speech language detection is automatic by default. If detection is not a good fit, choose a language from the in-app searchable list before transcription.

Useful for

- Adding captions before posting to social apps

- Making spoken videos easier to watch

- Creating captioned videos without typing every line by hand

Main features

- Choose one video and create captions automatically

- Burn captions into the exported video

- Preserve the video's orientation and aspect ratio

- Save the generated video to Photos

- Run transcription and export on device

- Use automatic speech language detection or choose a language
