Do auto caption apps upload my video?

Most do. Many caption apps send your audio or video to a server to transcribe it and send the text back, which needs a connection and hands your footage to a third party. Reelvana is the exception here: by default, transcription runs on the phone itself, so your video never leaves it and captioning works in airplane mode. Turn on the optional Cloud model for top accuracy and it sends just the audio track, never your video.

Which caption app is best for Arabic?

Reelvana. It transcribes Arabic speech on the device and lays the captions out right to left, and you can pick a larger speech model for higher accuracy on your dialect. Most caption apps treat Arabic as an afterthought.

Q: What is the best auto caption app for iPhone?

If privacy and Arabic matter to you, Reelvana is the best pick because it transcribes your speech on the device with Whisper and never uploads your video. CapCut is a strong free all-round editor with fast auto captions, and Captions is polished for talking-head creators. All three run on iPhone.

Q: Are auto captions accurate enough to post?

Usually, but you should always review them. Names, jargon, and fast speech trip up every transcriber. The best apps let you edit the text before it is locked in. In Reelvana, captions are editable before export, so you can fix any misheard word and adjust timing, size, and position first.

Captions are the single highest-return thing you can add to a short-form video, because most people watch on mute. Here are the auto caption apps worth using on iPhone this year, what each does well, and how they differ on the thing most roundups skip: where your video actually goes.

What makes a caption app good

Auto captioning has three parts, and most apps are only strong at one of them. First, the transcription has to be accurate on your voice, your accent, and your vocabulary. Second, you need to be able to style the words and fix mistakes before they are locked into the video. Third, and this is the part people forget to ask about, the app has to get the transcription done somewhere. Many send your footage to a server. A few do it on the phone. If you care about privacy or you record offline, that difference is the whole decision.
