About
SubTitler is an automatic caption app for adding burned-in subtitles and 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
- Correct frequently misheard names, brands, and specialist terms
All features are available for free. There is no paywall, subscription, or in-app purchase flow.
SubTitler does not include multi-video joining, automatic cutting, BGM, or manual timeline editing.
