Add captions to a video
Add Captions to a Video on Android
To add captions to a video on Android, open CapsAI in Chrome, upload the MP4 from your gallery, read the draft captions it writes from the speech, and download one MP4 with the captions burned in. Nothing is installed and nothing on the phone changes. Before the steps, it helps to separate three things people mean by "captions on Android", because each has a different answer. First, captions that appear while you watch: Live Caption on Android does this for any audio playing on the phone, and YouTube, Instagram and TikTok show their own captions to viewers. Second, captions a platform adds to your post: YouTube Shorts, Instagram Reels and TikTok can generate them when you upload, in their own look, visible only on that platform. Third, captions inside your own video file, so they travel with the MP4 wherever you send it. This page is about the third kind, done from an Android phone in Chrome, with Google Photos, YouTube, CapCut and Live Caption covered honestly afterwards. CapsAI takes one MP4 or MOV up to 10 minutes per upload, 500 MB per file on free minutes, and writes captions in 11 spoken languages, including English and Hinglish. A new account gets 3 free minutes.
Start with 3 free minutes. Watermark-free export comes with every paid pack.
Upload Video
For best results, upload a video with clear speech. You can review and edit the captions after generation.

Three things I wish I knew before switching to Android.
A plain two-line style such as Beast (free) reads well over a face. Keep the captions in the middle band so the Reels or Shorts buttons do not cover them.
Screen recording of a phone setting
Settings, then Sound and vibration, then Live Caption.
Menu names are what speech recognition guesses wrong. Retype them in the editor, then use Newsroom or another lower-third style so the text sits clear of the recorded interface.
Hinglish voice note over footage
Yaar, is phone ka camera night mode mein kamaal hai.
Pick Hinglish as the spoken language and the captions come out in Roman script as spoken. Poppins Italic (free) suits a casual tone.

Hold the button for two seconds until the light turns blue.
A word-by-word style such as Ice or Color Blend lands each instruction as it is said. Numbers are worth a second read before export.

How it works
How it works
Step 1
Open CapsAI in Chrome on your phone
Go to the page in Chrome and sign in with Google or an email code. There is nothing on Google Play to install, so any Android phone that runs a current Chrome works, and the same account opens on a laptop later.
Step 2
Pick the video from your gallery
Tap the upload area. Android shows its picker: choose Gallery, Google Photos or Files and tap the clip. Camera recordings are MP4 files and upload as they are. One file per upload, MP4 or MOV, up to 10 minutes long.
Step 3
Check the file size, then stay on Wi-Fi
Long-press the clip in your gallery to see its size. Free minutes take files up to 500 MB; a pack raises that to 10 GB. A big file is a slow upload on mobile data, so switch to Wi-Fi and keep Chrome in the foreground until the bar finishes, because Android slows down background tabs.
Step 4
Confirm the spoken language
English is preselected from this page. Change it if the clip is in Hinglish, Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada or Punjabi. Captions come out in the language spoken; there is no translation step.
Step 5
Fix the words with your thumb
The editor is laid out for a touch screen. Tap a caption, retype it with the phone keyboard, and type a new start or end time in seconds if a line lands late. Preview any of the 37 styles on your own clip; 8 export free and the rest come with any paid pack.
Step 6
Export and find the MP4
Tap export and wait for the render. Chrome saves the file to your default download location; open Chrome's menu and tap Downloads to see it, or open the Files app, which lists everything downloaded to the phone. From there, share it to Instagram, YouTube, WhatsApp or anywhere else.

Questions
Is there a CapsAI app for Android?
No. CapsAI is a browser tool, not an app, and there is nothing on Google Play. Open the page in Chrome on your Android phone, sign in with Google or an email code, and upload from your gallery. The editor is built for a touch screen.
Can Google Photos add captions to a video on Android?
Not from the speech. Google Photos' Android help page "Edit your videos with Google Photos", read 30 October 2026, lists trim, stabilize, crop, adjust, filters, text, audio, speed and music; its text tool lets you "Tap Text", type a message, choose a font and colour, and save a copy. It names no caption, subtitle or transcription tool, so every line would be typed and placed by hand.
Does YouTube add captions to Shorts I upload from Android?
YouTube generates captions from speech for uploads and Shorts, and it says the quality "may vary". Its "Enhance your Shorts" page for iPhone documents a Captions button in the Shorts editor; the Android version of that page, read 30 October 2026, lists only a Text tool. Either way, YouTube's captions live on YouTube and cannot be exported as part of your file.
Do Instagram and TikTok caption videos on Android?
Both offer in-app captions generated at posting time, in the platform's own look, visible only on that platform. If your video already has burned-in captions, turn the platform's own captions off when you post, or viewers see two sets. We have not quoted their help pages here because we could not read them on 30 October 2026.
What is Live Caption on Android, and can it caption my video file?
Live Caption shows captions on screen for audio playing on the phone; Google's page says it "automatically captions speech on your device" and that captions are "never stored". It is for listening, not for editing. It cannot write captions into a video you will send to someone else, which is what this page is about.
Is CapCut on Android a good option?
CapCut has an auto-captions feature inside a full editor on Android, so expect more steps than a single-purpose tool, and check whether your spoken language is in its menu. The CapsAI alternative page for CapCut covers how the two differ, including CapCut's own pricing pages, which we do not restate here.
Which Android video files work?
MP4 and MOV. Android phone cameras record MP4 in H.264 or HEVC, and both upload. If someone sends you an iPhone .MOV, Chrome on Android may show "Preview unavailable" because the browser cannot play HEVC in that container; the message says your captions will still be generated, and they are. Up to 10 minutes per video, 500 MB on free minutes, 10 GB with a pack.
Where does the captioned video go after export?
Chrome saves it to your default download location, as Chrome's own help page puts it (read 30 October 2026). Tap Chrome's menu, then Downloads, to open it, or find it in the Files app. From the Files app or your gallery you can share it to any other app.
Can I get an SRT file or a translation on Android?
No. The output is one MP4 with the captions burned in; there is no SRT, VTT or TXT download, and captions stay in the language spoken. CapsAI's English has been used most on Indian English; for other accents, run your own clip through the 3 free minutes and read the draft.
What the Android search results are actually about
Search "add captions to video android" and the first page is a mix of different problems. Google Drive Help explains how to add caption tracks to a video stored in Drive: that attaches a subtitle file you already have, such as SRT or VTT under 2 MB, from a computer, so Drive plays it with captions. It does not write captions and it does not change the video file. YouTube Help describes YouTube's own captions, shown only on YouTube. A Chrome extension on the same page captions streaming sites while you watch. None of those puts text into your MP4.
If you want a video that shows captions when you send it to anyone, on any app, the captions have to be rendered into the frames. That is the browser route above. The export is 1080p on Starter and up to 4K on Creator and Pro, and watermark-free export comes with every paid pack. For plain subtitles rather than styled captions, the auto subtitle generator on Android follows the same steps in Chrome.
Google Photos on Android: a text tool, not a caption tool
Google Photos is the editor most Android phones already have, so it is the natural first try. Its Android help page, read 30 October 2026, lists what the video editor does: enhance or stabilize, trim or export a still, crop or rotate, adjust, add an effect or filter, add text, change or mute the audio, change the speed, add music. The text section is simple: tap Text, tap Edit text to type, pick a font and a colour, tap Done, and save a copy. No step listens to the audio, so a 60-second clip with 20 spoken lines means 20 text boxes typed and placed by hand.
The page also notes that some tools need a minimum amount of memory or Android version, and that non-Pixel phones on Android 9 do not get video editing at all. For a title card, Google Photos is fine. For spoken captions, use a tool that transcribes.
YouTube's captions from an Android phone
YouTube writes captions from speech for long-form uploads and Shorts, in the video's default language only, and warns that because they are generated by machine learning "the quality of the captions may vary". Corrections are made in YouTube Studio. For Shorts made in the app, the iPhone version of YouTube's "Enhance your Shorts" page documents a Captions button that starts automatic captioning and lets you change font and text colour and fix the words, with a note that captions are "only available in certain languages and mobile devices"; the Android version of the same page, read the same day, lists a Text tool and no Captions section. When YouTube Studio cuts a Short from a longer video, it adds autocaptions where available and lets you restyle or disable them.
The limit that matters here: YouTube's captions exist on YouTube. If the same clip goes to Instagram, WhatsApp or a client, it goes without them. Burn the captions in first, upload the captioned MP4, and switch YouTube's own captions off for that video so viewers do not read two sets.
Instagram, TikTok and CapCut on Android
Instagram and TikTok both generate captions at posting time on Android, styled their way and visible only there. They are quick for a one-platform post; the moment the clip is reposted, forwarded or downloaded, the captions stay behind. We could not read their help pages on 30 October 2026, so this page describes them only in general terms.
CapCut is the Android editor most people name for auto captions. It is a full editor, so captioning is one feature among many, and the menus change between versions. If you already cut in CapCut, export the finished edit without captions and upload that MP4 to CapsAI for the caption pass. The CapsAI alternative page for CapCut compares the two and carries the pricing facts, so they are not repeated here.
Live Caption is for listening, not for your file
Live Caption is the Android accessibility feature found under the volume controls on Pixel phones and, in Google's words, "selected Android phones". Google's help page says that "with a single tap, Live Caption automatically captions speech on your device" and that all captions "are processed locally, never stored, and never leave your device". It captions what you are hearing, for you, in the moment. It does not create a file, it does not add text to a video in your gallery, and the languages on offer depend on the phone model.
If "captions on Android" brought you here because you want to read along with a video, turn Live Caption on and you are done. If you want other people to read captions on your video, you need the browser route or an editor.
Android file facts: MP4, HEVC, 500 MB and the iPhone .MOV
Android cameras record MP4. Newer phones often offer HEVC (H.265) for smaller files and H.264 for compatibility; both upload to CapsAI as recorded, so there is no conversion step. The practical check is file size, not codec: free minutes take files up to 500 MB, a pack takes files up to 10 GB, and every video is capped at 10 minutes. A long 4K clip is the usual way to pass 500 MB; trim it in Google Photos first, or caption it with a pack.
One Android-specific moment is worth knowing in advance. When an iPhone .MOV lands on your phone and you upload it in Chrome, the page may show "Preview unavailable" in the upload frame, with a note that this browser cannot play HEVC video. That is the browser failing to decode the preview, not the upload failing. The file is accepted, the captions are generated, and the editor previews through a format Chrome can play. Projects stay in your account for 1 day on free minutes and 3, 7 or 15 days by pack, so download the export soon after it renders.
