A teleprompter that captions, too.
You read down the lens, NexCam records the take, and then it captions it — word by word, on device, without ever sending your audio anywhere. No exporting to a separate captioning app, no re-uploading, no watermark. The whole job lives in one place.

Why prompting and captioning belong together
Captions are not optional anymore. Most short-form video is watched on mute, and captioned clips hold attention longer. But for most creators captioning is a second errand: finish the take in the prompter app, export it, open a captioning app, re-upload, restyle, export again. Every hop is a chance to lose quality, lose sync, or lose the afternoon.
NexCam already knows what you said — you read it from the teleprompter. So captioning is not a separate project bolted on at the end. It is the natural next step in the same app, on the take you just recorded.
Caption Studio, in the same app
After a take, Caption Studio generates word-synced captions on device and gives you real control over how they look — the kind of styling that usually means a separate subscription tool.
- Eight styles from clean Classic to Bold Karaoke, so captions match the tone of the video instead of fighting it.
- Karaoke word-highlighting that lights up each word as it is spoken — the look that keeps eyes on the screen.
- Custom fonts, sizes, colors, and uppercase, so the captions read as part of your style, not a default overlay.
- Burn-in or sidecar export. Bake the captions into the video, or export a separate SRT or VTT file to upload alongside the clip.
Transcription runs entirely on your iPhone. There is no upload, no account, and no internet required — your audio never leaves the device. Read the full on-device commitment.
Burned-in or a sidecar file — when to use each
Burn them in when you are posting to TikTok, Reels, or Shorts and want the captions to look exactly the way you styled them, on every player, guaranteed. The captions become part of the video pixels, so nothing can strip or restyle them.
Export an SRT or VTT when you are uploading to YouTube or a site that reads caption files — that keeps captions selectable, searchable, and translatable, and lets viewers turn them off. NexCam gives you both from the same take, so you are never boxed in. If you want the deeper how-to, see how to add captions to a video on iPhone.
One take, all the way to published
Because the prompter, the camera, and the captions are the same app, a finished captioned clip is a few taps from the read — not a relay race across three tools:
- Read down the lens with the script in a band beneath the camera, scrolling to your voice.
- Record crash-proof, with every second written to disk so a crash or a call can never lose the take. How that works.
- Caption in Caption Studio, styled to match the video.
- Export watermark-free at 1080p or 4K, in 9:16, 16:9, or 1:1.
Common questions
Is there a teleprompter app that also adds captions?
Yes — NexCam prompts, records, and captions in one app. After a take, Caption Studio generates word-synced captions on device, with eight styles and karaoke highlighting, and exports them burned in or as a sidecar SRT or VTT.
Are captions made on device or in the cloud?
On device. Transcription runs entirely on your iPhone, with no upload and no account, so it works offline and your audio never leaves the phone.
Can I export an SRT, or only burned-in captions?
Both. Burn captions into the video, or export a sidecar SRT or VTT to upload alongside the clip. Burned-in exports stay clean at 1080p and 4K with no watermark.
