Create with confidence

Find help with captions, photo and video editing, exporting your work, and common questions.

Your privacy comes first

Your photos, videos, projects, caption processing, and video rendering stay on your device. CaptionFrameX does not upload your project media to its servers or sell your personal information. A speech-recognition model may need to download before first use; your audio or video is not sent to the model provider to download it. Apple handles subscription payments. Files leave the app only when you choose to share or export them.

Get started

Go from choosing your media to a finished edit, all within a project.

  1. Choose your media. Select a photo or video from the Home screen to create a project.
  2. Create captions and edit. Generate captions for a video, review the text and timing, and explore available styles and animations. Adjust your photo or video with the app's editing tools.
  3. Preview and export. Review your result, export the finished video, or create an SRT or VTT subtitle file.

Frequently asked questions

Where are my projects and media stored?

Your projects and imported media are kept in the app's private storage on this device. They are not uploaded to a CaptionFrameX server.

Does CaptionFrameX send my video or photos anywhere?

No. Editing, caption processing, and rendering happen on your device. Media leaves the app only if you choose a sharing or export option.

Why does caption generation need a download?

The speech-recognition model may need to download once before first use. It is stored locally afterward. Your audio or video is not sent to the model provider to download the model.

How do I create captions for a video?

Open a video project, go to the caption controls, choose the language and recognition options, and generate captions. Review the text and timing before exporting.

Can I change the look and motion of captions?

Yes. Choose from the available caption styles. Depending on the style, options may include fonts, colors, emphasis, and word or caption animations.
