Burncaps is a browser tool that burns animated word-by-word captions into your video, or cuts a talking video to its strongest 30 or 60 seconds. Your video opens in the page, the AI listens on your device, and you choose what comes out.
Your file opens directly in the page and the video is never uploaded, which you can verify in your browser's network tab. OpenAI's open-source Whisper model runs in your browser and times every single word. On a phone, for a language other than English, or when you ask for a closer transcript, you can choose our speech service instead: faster and more accurate, and it gets only the sound, never the picture.
The whole video: animated word-by-word captions burned in, nothing cut. Keep your room as it was, or blur it, put a studio colour or your own picture behind you, or a green screen to key out later. The best 30 or 60 seconds: ums and dead air cut, the moment chosen from your transcript and ended where your voice actually finishes the point, your product names spelled right, a 9:16 window placed on your face, the background softened or swapped for a studio black, white, grey or a colour of your own, an opening card, and a beat at the end that fades instead of stopping.
Your transcript opens as a script under the video. Click any word to correct it (a product name the model has never heard, say), fix it everywhere in one click, and the captions follow. Pick one of twenty caption styles and your browser encodes the finished file, usually under a minute. Subtitle files come free with every video.
No B-roll, no stock music, no picking twenty clips from a two-hour podcast. It is for one recording of up to ten minutes: caption it, or cut it to its best half minute. Export is fastest in Chrome or Edge on a computer; many phones export too, more slowly.
Word-by-word highlight animation, the format proven to hold attention on short-form video, in the looks creators use most right now: keyword highlights, the native text box, words that ink in, tall capitals, a sliding underline and more. Every style is included in every video, free or Pro. Every thumbnail below is rendered live by the engine.
Free to use, for as many videos as you like. Your first two carry no mark, so you can judge the result on your own footage; after that each video carries a small burncaps.app mark, or one payment removes it for good. Pro is never a subscription.

| What matters | Burncaps | Typical caption app |
|---|---|---|
| Price | Free to use: no mark on your first two videos, then a small mark, or $49 once for none | $10 to $25 a month |
| Watermark on free videos | None on your first two; a small burncaps.app mark after, which Pro removes | Usually, from the first video |
| Your video on their servers | No. It stays on your device | Yes |
| Account required | No | Usually |
| Free videos | As many as you like with every feature; no mark on the first two, a small mark after | Minutes-per-month caps and a watermark |
Nothing, for as many videos as you like, with every feature included: both outputs, all twenty styles, every background, the max-accuracy model, no account. Your first two videos carry no watermark; after that each video carries a small burncaps.app mark in a corner. Pro, $49 once, removes the mark from every video, and Pro is not a subscription. Subtitle files are free without limit.
The whole video keeps every second you recorded and burns animated captions in; you can leave your room as it was, blur it, or put a studio colour, your own picture or a green screen behind you. The best 30 or 60 seconds is an edit: ums, stutters and dead air are cut, the strongest stretch is chosen from your transcript and ended where your voice finishes the point, your product names are spelled right, a 9:16 window is placed on your face, the background is softened or replaced with a studio backdrop, an opening card carries your line, and the ending holds for a beat and fades instead of stopping. You can switch between them after the transcript arrives.
Yes. Choose a shape for the whole video: Original, Vertical 9:16 for TikTok, Reels and Shorts, Square 1:1, or Portrait 4:5 for the Instagram feed. Follow me keeps you in frame like a calm camera operator: it stays still while you stay near the middle and moves smoothly when you step away. Fixed lets you drag the picture into place and zoom in. Fit everything shows your whole frame with nothing cut, for slides, screen recordings or two people. Every caption style and background works in every shape, and a landscape take cut to vertical is enlarged, so it is a little softer than the original.
Yes. Your transcript opens as a script under the video. Click the word, type the right one, and the captions and subtitle files follow. If the same word is wrong elsewhere, one click changes them all, and this browser remembers the fix for your next video. Typing your product and company names into the names box before you start catches most of them up front.
No. The model downloads into your browser; your video never leaves it. The sound can leave only if you choose our speech service, which a phone offers for speed and a computer offers for a language other than English, for a slow computer, or when you ask for a closer transcript: then it goes in short pieces to Microsoft's MAI-Transcribe in the EU, never the picture, and nothing is kept. Before and after an export the page makes one small check with our server, carrying a random ID for your browser and nothing from the video (only a finished export uses a free video), and each page asks once which price applies where you are, carrying nothing about you. The transcript text can leave only when you choose the 30 or 60 second cut, type names to spell right, or choose a caption language, sent to our AI to choose the stretch, fix the names or translate the lines; it is not stored, and ticking "Keep everything on this device" stops it. An email you type, to hear from us or to send yourself this page, goes to our server and nothing else from the page goes with it. You can verify all of this in your browser's network tab.
A recent browser. Chrome or Edge on a computer is the fastest and surest, because they use the graphics chip to write the video; Firefox may save a WebM file instead of an MP4, and many phones export too, more slowly. Where a browser cannot write video, you can still transcribe and download SRT, VTT or ASS files.
37, the list in Listening settings. It listens first and names the language it hears above your script, with a one-click change. Twelve Indian languages, Hindi, Urdu, Bengali, Tamil, Telugu, Gujarati, Marathi, Kannada, Malayalam, Punjabi, Nepali and Odia, can be written by our speech service (Microsoft's MAI-Transcribe, which names the language by itself and gets only the sound) or on your own device by a speech model made for each (AI4Bharat IndicConformer, open source, 138 MB once per language); Burncaps asks once which you want. On Google FLEURS test recordings the service got about 94 in 100 words right in Hindi, 85 to 86 in Urdu, Bengali and Punjabi, 78 to 83 in Telugu, Gujarati, Marathi, Kannada, Malayalam, Nepali and Odia, and 69 in Tamil; the on-device models got about 89 in Hindi, 84 in Bengali, 72 to 81 in most others, 68 in Nepali and 60 in Malayalam. Accuracy is best in English and the major European languages; for a strong accent, Max accuracy in Listening settings got about three times fewer words wrong in our test on Indian-accented English. Sinhala and Assamese speech is not written well by any speech model that runs in a browser yet, and Burncaps says so rather than guess; captions in them on an English video work, through Captions in. Pages for Hindi · Urdu · Bengali · Tamil · Telugu · Gujarati · Marathi · Kannada · Malayalam · Punjabi · Nepali · Odia · Spanish · Portuguese · Arabic · Indonesian · Tagalog · French · German.
The speech model downloads once (about 190 MB on a computer with a graphics chip, about 80 MB without one) and is kept by your browser. Burncaps starts fetching it the moment you reach for a file, and after the first time the words start appearing on your video within seconds. A video in one of the twelve Indian languages also downloads the model made for that language, 138 MB once, unless you choose our speech service, which needs no download at all; on a phone the service answers in seconds, where a phone’s own model takes minutes. The max-accuracy model is a 1.4 GB download, once.
Unlimited videos and exports with no mark, and no daily, monthly or lifetime cap. Up to ten minutes and 1.2 GB per file on a computer, the same as free. Translations and best-moment picks are unlimited for your own use, with a safety limit per account that we do not publish and that resets at midnight UK time. Five hours of our speech service in any 30 days, then your own device listens. Three devices at once. Features added later come with it, and Pro is not a subscription. Nothing in Pro today is ever moved into another plan. Every limit is set out in plain words in About.
