Checked 21 October 2026 from each product’s public pages; prices and plans change, so confirm them before you buy.
Every app here listens to the speech in a clip and writes timed captions over it. They differ in three things that matter more than the feature lists: whether the video leaves your phone, whether you pay a subscription or per use, and how much editing the app does beyond captions. This list is written by the maker of Captions Cut, which is on it; the other apps are described from their App Store pages and sites, as checked on 21 October 2026.
1. Captions Cut ours
Best for word-by-word captions, pay per second, video never uploaded.
Captions Cut (“Captions Cut: Auto Subtitles” on the App Store) does captions only, and does them word by word: the spoken word is highlighted as it is said, in one of 48 styles. 53 spoken languages plus Auto detect; every word editable; translation into a second line with Pro; export to Photos in 1080p or 4K. The video stays on the phone: only the audio track is uploaded for transcription, then deleted. No account is needed. The app is free; captioning costs 1 credit per second of audio, with packs from $2.99 that never expire, or Pro at $7.99 a month. The same credits work in the web editor. It is the one on this list we make.
2. CapCut
Best for a free, complete video editor with captions inside.
CapCut, ByteDance’s editor, is the app most short-form creators already have. Auto captions are one tool among cuts, transitions, effects, music and templates. The video is uploaded for captioning. The editor is free; CapCut Pro, as of October 2026, is listed around $19.99 a month or $179.99 a year in the US (lower tiers and regional prices exist) and unlocks 4K export and the full toolkit. Pick it if you want to edit and caption in one place. Captions Cut vs CapCut.
3. Captions
Best for AI dubbing, avatars and eye-contact correction alongside captions.
Captions started as a caption app and is now an AI video studio: captions, AI dubbing into other languages, AI avatars, eye-contact correction, AI editing. Processing happens in the cloud, on a subscription whose entry tier third-party listings put around $9.99 a month, as of October 2026, with generative features in a higher tier. Pick it if you want those generative features in one app. Captions Cut vs Captions.
4. Submagic
Best for captions plus automatic emojis, zooms and b-roll, on a plan.
Submagic is a web service with mobile apps, aimed at creators and agencies who want captions with extras added for them: emojis, zooms, b-roll, sound effects, and Magic Clips that cut long videos into shorts. The video is uploaded. Plans, as of October 2026, start around $19 a month with a cap on videos per month; the free trial watermarks a few short videos. Pick it if you want the extras and a desktop workflow. Captions Cut vs Submagic.
5. SnapScript
Best for captions made entirely on the phone.
SnapScript transcribes and renders on the device, so nothing is uploaded at all, not even the audio. The trade-off is the on-device model: accuracy and language coverage depend on it, and processing uses the phone’s battery and time. Pick it if even an audio upload is too much.
6. Subtitle Maker: AI Captions
Best for on-device Whisper transcription with many animations.
Subtitle Maker runs Whisper on the phone and lists 50-plus languages and dozens of word animations, including karaoke-style highlighting. As with SnapScript, nothing leaves the device, and speed depends on the phone. Pick it for offline captioning with plenty of animation choices.
7. Clips
Best for quick, free captions from Apple.
Apple’s Clips adds Live Titles as you record, free and without an account. The captions are plain and tied to Clips’ own recording flow rather than to footage you already have, and the styling choices are few. Pick it for a quick caption on a clip you are shooting right now.
How to choose
- Where does the video go? CapCut, Captions and Submagic upload the whole video. Captions Cut uploads only the audio and deletes it. SnapScript and Subtitle Maker upload nothing.
- How do you pay? CapCut Pro, Captions and Submagic are subscriptions. Captions Cut charges per second of audio, with packs that never expire. SnapScript and Subtitle Maker have their own one-off or subscription pricing; check the App Store.
- Do you want more than captions? Only if you do should an editor or an AI studio win over a captions app.
- Will you read the captions before posting? Every app here makes mistakes on names and noise; the ones with a word-level editor make fixing them quick.
