Captions for Instagram, TikTok and YouTube Shorts
Upload the clip as your phone saved it — a vertical MP4 or MOV — and try it here, with no account. In an account, you fix the words first, then burn the captions into the video and download the finished file to post; it works on every plan, Free included, and the captions are in the picture, so they show wherever the video is watched, sound on or off.
Upload a file
Audio or video from your device.
Record
Your microphone, recorded in this browser.
Keep this page in front while you record. Switching to another app or locking the screen makes the browser stop the microphone, and what was missed can’t be recovered.
Keep this tab open while you record. If you close it or open another page in it, the recording is lost.
Auto detect can mishandle a recording that switches language.
Free: one recording up to 10 minutes · its transcript to read · no account · deleted after 48 hours
What you get
In an account — free or Pro, with the same features — the transcript comes with:
- Captions burned into the video
- The finished video, with the captions in the picture, ready to download and post — on every plan, Free included. Fix the text before you render: the captions are fixed when the render is asked for, so a later edit goes into the next render.
- The words first, with a time on every word
- Click any line to hear it; the captions follow the word times, so a caption appears when the words are spoken.
- Editing in the text itself
- Names, slang, the product you are talking about: fix them where they sit, before you render.
- Subtitle files instead
- Word (DOCX), TXT, SRT and VTT, on every plan — SRT or VTT if your editor or platform takes a caption file rather than captions in the picture.
- Who spoke
- In American English, British English and Indian English, the transcript separates the voices into Speaker 1, Speaker 2 and so on; you rename each label once, and the name holds for the whole transcript. In Australian English and Philippine English, it separates them too, on recordings of up to 2 hours. If the separation fails, the transcript comes without speaker labels, and says so.
Short clips, the trial preview and what is not captioned
A short clip is short: in the no-account trial, you can read everything it transcribes, and the result page says what you are seeing. Music and sound effects are not captioned, and text already in the picture is not read — only speech becomes captions. Every automatic transcript has errors, and they cluster on proper names, numbers and technical terms. Before you quote a passage, click the line and listen: with a time on every word, that check takes seconds. In a short clip that is the name or product you say once, which the whole caption hangs on.
Where several people talk over each other in the clip, the captions need review before you render. Hold the phone close when you film, and the text comes back with fewer errors.
Longer videos
Without an account, the trial transcribes up to the first 10 minutes of a recording. On Pro, each file can be up to 8 hours, within the month's included hours; what each plan includes, the pricing page shows. See plans and prices.
On long recordings, speaker labels can wander from one section to the next — a consequence of how long audio is processed, not a setting.
Before you upload
Name the main language rather than leaving it on automatic. Automatic detection has to decide what language each stretch of speech is in, and where a recording switches language, what was said in the other one may come back translated instead of transcribed — or not come back at all. Either way nothing is marked as missing: the transcript will look complete.
Philippine English is marked “preview” in the language list: offered, but without a quality commitment yet, so check its transcript more closely before you use it.
Frequently asked questions
- How much does it cost to caption a video?
- To try it, nothing: without an account, the trial transcribes up to the first 10 minutes of a recording, and the result page shows what you can read without paying and how to read the rest. What the free account includes today and Pro's prices are on the pricing page.
- Do I need an account to burn captions into the video?
- Yes: the trial on this page gives you the transcript; burning the captions into the video and downloading the finished file is done in an account. Burning captions into a video works on every plan, Free included, for recordings up to your plan's file length and 2 hours at most; each month an account can make 20 such videos, 600 minutes of video in all, and a finished video is kept for 7 days.
- Does it tell the people in the clip apart?
- In American English, British English and Indian English, the transcript separates the voices into Speaker 1, Speaker 2 and so on; you rename each label once, and the name holds for the whole transcript. In Australian English and Philippine English, it separates them too, on recordings of up to 2 hours. If the separation fails, the transcript comes without speaker labels, and says so.
- Which video files can I upload?
- The clip as your phone saved it: we accept MP3, M4A, WAV, OGG, Opus, MP4, MOV and WebM, among others.
- What happens to the clips I upload?
- Your recordings and transcripts are not used to train models. In the no-account trial, the file and the transcript are deleted 48 hours later — or 7 days after payment, if you buy just that transcript; in an account, they are kept until you delete them.
