The best app to automatically generate subtitles depends first on which phone you hold. On iPhone, Instagram Edits, CapCut, Captions, VN and InShot all generate captions from speech, and Edits does it with no watermark and no paid tier listed. On Android, the choice is shorter than most lists admit: CapCut, VN, InShot and YouTube Create generate captions, Captions ships only as "Captions Lite", a manual editor, and Clipchamp has no Android app at all. Every fact in this post was read from the vendor's own App Store listing, Play Store listing or help page on 28 Oct 2026, and the table below shows the free-tier and watermark terms each one states.
If you do not want to install anything, both phones already caption live audio. Android Live Caption and iOS Live Captions put words on screen while audio plays, on the device, but neither saves those words or writes them into the video file. For captions that stay in the video, you need an app or a browser tool. CapsAI is one browser route: it runs in the phone browser, with no app, no APK and no install, and exports an MP4 with the captions burned in. More on both at the end.
Android vs iPhone: which caption apps exist on each
This is the table the top results skip. "Android" and "iPhone" mean the app, as listed by the vendor today, generates captions from speech on that platform. "Free tier and watermark" is what the listing or help page says, nothing more.
| App | Android | iPhone | Free tier and watermark, as listed 28 Oct 2026 |
|---|---|---|---|
| CapCut | Yes, APK download page on capcut.com | Yes, iOS 15 or later | Free with in-app purchases; Standard $9.99 a month; watermark terms not on the listing |
| Captions | Captions Lite only, manual editing, Android 7.0 or later | Yes, iOS 16 or later | Free with in-app purchases; Basic $9.99 a month; watermark terms not on the listing |
| Instagram Edits | Google Play listing reported at the April 2025 launch; Play text not readable today | Yes, "Only for iPhone", iOS 16.3 or later | Free; "no watermark" |
| YouTube Create | Android phones with at least 4 GB of RAM, listed countries only | iPhone XR or newer, iOS 17 or later | No price on the help page; captions only for clips up to 60 seconds |
| Canva | Play text not readable today | Yes | Free with in-app purchases; Canva Pro $14.99 a month; caption plan terms not readable today |
| VN | Yes, store and APK | Yes | "Free with No Watermark"; VN Pro $7.99 |
| InShot | Yes, Google Play and AppGallery | Yes | Free with ads; Pro $4.99 a month; watermark terms not on the listing |
| Clipchamp | No Android app | iOS app unsupported since 9 June 2026 | Web and desktop only |
| Android Live Caption | Built in, Pixel and selected phones | Not applicable | Free; live on screen only, nothing saved |
| iOS Live Captions | Not applicable | Built in, iPhone 11 or later | Free; live on screen only, nothing saved |
| CapsAI | Phone browser, no app | Phone browser, no app | 3 free minutes to start; packs from $4 paid once; watermark-free export comes with every paid pack |
Two rows deserve a closer look before you pick. Captions on Android is not the Captions app iPhone users talk about, and Clipchamp has left phones entirely. Both are explained below.
What each app does, from its own listing
Instagram Edits
Edits is Instagram's standalone video editor. Its App Store listing says it can "Generate captions automatically and customize how they appear in your video" and that you can "Export your videos in 4K with no watermark and share to any platform." The listing is marked "Only for iPhone" and needs iOS 16.3 or later. It shows an In-App Purchases label but lists no purchases, so there is no paid caption tier to read today.
Edits launched on Google Play in April 2025 according to the press coverage of the launch, which quoted the same "no added watermarks" line. The Play Store listing itself could not be read today, so the Android row in the table is marked as reported, not confirmed. For Reels specifically, the best caption apps for Instagram Reels covers Edits alongside the Reels in-app captions.
CapCut
CapCut's App Store listing describes "Auto captions: automate speech recognition and subtitles in videos." It is free with in-app purchases, and the purchases listed are a Standard monthly subscription at $9.99, a Pro monthly subscription at $19.99 and a yearly subscription at $89.99. The listing does not say what a free export looks like or whether captions sit behind the subscription, so this post does not say either. On Android, CapCut's own download page links to an APK, and CapCut Online runs in a browser.
CapCut is the app most people are leaving when they search this phrase, usually over the subscription. Captions app vs CapCut compares the two paid editors in detail, so that comparison is not repeated here.
Captions
The Captions app's iPhone listing claims it can "Automatically generate accurate captions or subtitles in 91+ languages". That is the vendor's claim. The listing shows Captions Basic at $5.99 a week, $9.99 a month or $64.99 a year, and Captions Max at $24.99. It needs iOS 16 or later.
The Android answer is the one most searches miss. Captions' own Android help page says "Captions Lite for Android" "brings essential manual video editing to your phone" and that "Captions Lite offers advanced tools for manual editing and is only available on Android." The page's feature table compares Free and Lite tiers on caption styles, teleprompter, dubbing and transcript copy, and the install step is "In the Play Store, search for Captions Lite." It requires Android 7.0 or newer. So yes, there is a Captions app on Android, but it is a different product from the iPhone app, and the help page describes it as a manual editor. If the free tier is your real question, is Captions AI free reads the current plan page.
YouTube Create and YouTube Studio
YouTube Create is Google's phone editor. Its captions help page says to tap Captions in the toolbar, choose all videos or just the voiceover recorded in the app, pick the language and tap Generate. The hard limit is in the same article: "YouTube Create cannot generate captions for clips longer than 60 seconds." The page says "YouTube Create is available on Android phones (with at least 4GB of RAM)", and lists iPhone XR and newer on iOS 17 or later, in a set of listed countries.
YouTube Studio is a different path. YouTube Help says "YouTube uses speech recognition technology to automatically create captions for your videos" after upload, and that "Automatic captions will be in the video's default language only." Those captions are a closed-caption track viewers can switch off, not text in the picture, and the editing steps on that page are for studio.youtube.com, not the Studio app.
Canva
Canva's App Store listing says you can "Add captions, apply cinematic effects like slow motion, sync your edits to music with Beat Sync". The app is free with in-app purchases, and Canva Pro is listed at $14.99 a month or $119.99 a year. Canva's feature page and its captions help article refused the fetch today, so this post does not state whether caption generation in the app needs Pro. Check the Captions panel in the app before you count on it.
VN
VN is the plain option. Its App Store listing headline is "Free with No Watermark", the auto captions feature is described as "Automatically generate subtitles from audio", and the paid VN Pro is listed at $7.99 or $69.99 with small credit packs from $1. VN's site offers iOS, Android, Mac and Windows downloads, including a direct Android APK, and repeats "no watermarks - all for free".
InShot
InShot's listing says "Auto Captions. Generate subtitles and captions with AI speech-to-text tool." and adds "Bilingual Subtitles". The app is free with advertising, and the listed purchases are InShot Pro at $4.99 a month, $19.99 a year or $49.99 for life, plus a $3.99 Remove ads purchase. The listing does not mention a watermark one way or the other. InShot's site links the App Store, Google Play and Huawei AppGallery.
Clipchamp
Clipchamp mobile no longer exists in a useful sense. Microsoft's support page says "Beginning June 9, 2026, the Clipchamp iOS app will no longer be supported", and "The Clipchamp web and desktop applications will remain fully functional." The page does not mention an Android app, and the Play Store and App Store URLs returned nothing today. If you saw Clipchamp on a 2024 list, treat it as a desktop and web tool now.
The free options built into the phone, and what they cannot do
Both operating systems caption speech without an app. Neither replaces a caption app for publishing.
Android Live Caption. Google's help page says "Live Caption automatically captions speech on your device." It works on videos, podcasts, phone calls, video calls and audio messages, not music. It is on-device: "All captions are processed locally, never stored, and never leave your device", and "Live Caption doesn't use mobile data or an internet connection" after the first language download. Languages depend on the phone: English only on Pixel 2 and 3, seven languages including Hindi on Pixel 4 and 5 and selected phones, and fifteen on Pixel 6 and later and selected phones running recent Android.
iOS Live Captions. Apple's iPhone guide lists it for iPhone 11 or later, captions conversations nearby or audio playing on the phone, and says it is not available in all languages, countries or regions. Apple also warns that accuracy may vary and that the feature should not be relied on in high-risk or emergency situations. Apple's accessibility page describes a related feature, generated subtitles for videos, which uses "on-device speech recognition" and is "available in English in Canada and the U.S."
The shared limit is the one that matters for creators. Both features draw text over the screen for the person holding the phone. The words are never stored, never exported and never written into the video file. If you record a Reel, turn on Live Caption and upload, your viewers see no captions. The system features are for watching, and apps are for publishing. Adding captions to a video on iPhone and Android walks through the publishing steps on both phones.
Picking by situation
You want free with no watermark, and you are on iPhone. Edits lists "no watermark" and no paid tier. VN lists "Free with No Watermark" on both platforms.
You are on Android and want the same. VN is the listing that says it. CapCut and InShot both generate captions on Android, but neither listing states its watermark terms, so test an export before you plan a channel around either.
You asked "is Captions AI for Android". The answer from Captions' own help page is Captions Lite, a manual editor for Android 7.0 and newer. The automatic 91-language captioning the iPhone listing advertises is not what the Android help page describes.
Your clips are longer than a minute. YouTube Create stops at 60 seconds per clip. The other apps above do not state a clip limit on their listings. CapsAI takes videos up to 10 minutes.
You speak Hinglish or an Indian language. Live Caption on Pixel 4 and later includes Hindi. Among the apps, the listings say "multiple languages" without naming them, so check the language picker before buying. CapsAI's 11 spoken languages are Hinglish, English, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada and Punjabi, and the Hinglish caption generator is the page for mixed Hindi and English speech.
You do not want another app on the phone. Read the next section, then the subtitle app for Android or iPhone page, which answers whether you need an app at all.
The browser route: no app, no APK
CapsAI has no native Android app, no iOS app and no APK. It runs in the phone browser. You upload an MP4 or MOV up to 10 minutes long, choose the spoken language from the 11 above, read the timed draft against the audio, fix any word or timing, pick a caption style and export an MP4 with the captions burned in. That file plays with its captions on every platform, because the text is part of the picture.
The limits are plain. It exports a burned-in MP4 only, with no SRT or VTT file, and it does not translate or caption live audio. You get 3 free minutes to start. After that, packs cost $4, $9 or $19 paid once, which is ₹49, ₹99 or ₹299 in India and €4, €9 or €19 in the euro area, and watermark-free export comes with every paid pack. There is no subscription to cancel, which is the difference most people searching this phrase are looking for after CapCut or Captions.
The auto subtitle generator that runs in your phone's browser has its own page with the full description. If your question is how a phone-only editing routine fits around it, the mobile-only video editing workflow covers recording, editing and captioning in order.
Summary
- Edits is the only app above whose listing says both "no watermark" and no paid tier, and it is marked iPhone only on the App Store.

- Clipchamp's iOS app has been unsupported since 9 June 2026 and there is no Android app.
- Android Live Caption and iOS Live Captions are live, on-device and never saved, so they do not caption a video for upload.
