Auto subtitles for facecam videos on iPhone
ReactCam turns your voice into subtitles automatically: record your facecam reaction or voiceover commentary, tap to generate subtitles from that audio, then style and edit every line before export. No separate captioning app, no re-uploading to a web service.
How it works
- Record your reaction. Facecam or audio-only commentary — subtitles are generated from whichever voice track you record.
- Generate subtitles. ReactCam transcribes the recorded audio into subtitle lines placed on your video.
- Style them. Pick the font, size, alignment, background, and the word-highlight color that follows your speech.
- Edit anything. Fix a misheard word, rewrite a line, or delete subtitles you don't want — all inside the project.
- Export. Subtitles render into the final video, up to 4K.
Why subtitle your reactions
- Muted autoplay. Most feeds play video silently — subtitles keep your commentary landing even with the sound off.
- Retention. Viewers hold on captioned videos longer, and the word-by-word highlight draws the eye.
- Accessibility. Deaf and hard-of-hearing viewers can follow your content.
Record, subtitle, export — one app.
Frequently asked questions
Can I edit the subtitles after they're generated?
Yes. Every generated line is editable inside your project — fix a word, restyle the text, change alignment or highlight color, or delete lines entirely.
Do subtitles work for audio-only commentary too?
Yes. ReactCam can record voiceover commentary without the camera, and subtitles are generated from that recorded audio the same way.
Why do subtitles matter for reaction videos?
Most short-form video is watched with the sound off. Subtitles keep your commentary readable on mute, which improves watch time on TikTok, Reels, and Shorts.
