Best Apps to Translate Video Subtitles on iPhone

Most caption apps can write subtitles in the language you speak. Fewer can translate them, and they don't all do it the same way. Some give you translated subtitles burned into the video, some give you a subtitle file, and some replace your voice entirely.

This list covers apps that run on an iPhone. One of them, CapCap, is the app we make. We've tried to be fair about where the others are a better pick.

Prices are the in-app purchases listed on the US App Store, checked on October 17, 2026. They change, so check the listing before you pay.

What to look for

• Translated subtitles you can edit. Machine translation gets names, slang and jokes wrong. You need to be able to fix a line before you post.
• A subtitle file (SRT). If you post on YouTube, a file lets viewers pick their language from the CC menu instead of reading text burned into the video.
• Styling. For Reels and TikTok the subtitles are drawn into the video, so fonts, colors and placement matter.
• Dubbing, if you want it. Some apps can also replace the voice. That's a different job; see our dubbing app roundup.

1. CapCap

CapCap transcribes your video, translates the transcript and times the translated lines to the speech. You can edit any sentence, style the subtitles, then save the video with them burned in or export them as an SRT file. It can also dub the translation if you want a voice track.

• Good for: translated subtitles you want to check and style, and SRT files for YouTube.
• Watch out for: iPhone only (iOS 18 or later). One translation language per project, so each extra language is a new project.
• Price: free plan with 3 captioned videos a month, up to 3 minutes each, with a small watermark. Pro is $14.99 a month or $59.99 a year, and removes the limit and the watermark.

2. Captions (by Mirage)

Captions is a full AI video editor with a chat-based editor, AI edits and avatars. Its App Store description says it generates subtitles in 91+ languages and dubs into 29.

• Good for: people who want one app for editing, captions and translation and don't mind paying more.
• Watch out for: most of the app is built around AI editing, so it's a lot of app if you only need translated subtitles.
• Price: Captions Basic is listed at $9.99 a month or $64.99 a year, and Captions Max at $24.99. The company's site says there is a free version.

3. VEED Lite

VEED Lite is the quick-edit iPhone app from VEED, the web video editor. Its description lists auto captions in several styles, translation into other languages, and removing silences and filler words, for clips up to 10 minutes.

• Good for: people who already use VEED on the web, or want silence removal along with captions.
• Watch out for: the 10-minute clip limit in the Lite app. VEED's full app and website handle longer videos.
• Price: "Mobile PRO" in-app purchases are listed from $2.99 to $51.99, depending on the plan length.

4. InShot

InShot is a general video editor. Its App Store description lists AI auto captions and bilingual subtitles, which show your language and a second one together.

• Good for: bilingual subtitles inside a cheap, full video editor.
• Watch out for: captions are one feature among many, not the focus of the app.
• Price: InShot Pro is listed at $4.99 a month, $19.99 a year or $49.99 once.

5. HeyGen: Translate Video

HeyGen Translate is built for dubbing: its description says it dubs into 175+ languages, clones your voice and can re-sync your lips to the new language. It can also add captions in any language.

• Good for: talking-head videos where you want viewers to hear you in their language, not read subtitles.
• Watch out for: it's priced for dubbing. If you only need subtitles, the apps above cost less.
• Price: HeyGen Creator is listed at $10 a week, $29 a month or $279 a year, plus credit packs from $4.99.

Which one to pick

• Subtitles you check and style, plus SRT for YouTube: CapCap.
• An all-in-one AI editor: Captions.
• You already edit in VEED: VEED Lite.
• Two languages on screen at once: InShot.
• Your face on camera, speaking the new language: HeyGen.

Whatever you use, read the translation once before you post, or ask someone who speaks the language to watch it.
