MP4 and MOV video, or MP3, WAV, M4A and other audio. The file opens directly in the page and is never uploaded, which you can verify in the network tab; the only sizeable download is the one-time model fetch.
Whisper times every single word. Click any word to correct it, double-click to jump the playhead there. Names, brands and jargon take seconds to fix before they reach the file.
SRT for YouTube and social uploads, VTT for the web, ASS for typesetting tools, or plain text for show notes. Or burn the captions straight into a new MP4 on the main page.
SRT (SubRip Subtitle) is the plain-text standard the whole industry accepts: numbered cues, start and end timecodes, caption text. YouTube, Instagram, LinkedIn, Vimeo, Premiere Pro, DaVinci Resolve and Final Cut all take it. Platforms index subtitle text, viewers watching on mute keep reading, and accessibility improves. One small file, three jobs done.
| What matters | Burncaps | Typical online SRT site |
|---|---|---|
| Price | Subtitle files free, unlimited. Burned-in video: free, with no mark on your first two, then a small mark or $49 once | Free trial minutes, then a subscription |
| Length limits | None | Minutes-per-month caps |
| Sign-up | None | Account before download |
| Your file | Stays on your device | Uploaded to their servers, queued |
| Word-level editing | Click any word, then export | Varies; often behind the paywall |
No. Because transcription can always run on your own device, there is no server bill to protect with minute caps. An hour-long podcast episode works the same as a 30-second clip; longer files simply take longer to process on your machine.
SRT, VTT (the web-native subtitle format), ASS (used by advanced players and typesetting tools) and plain text. You can also burn the captions into the video itself as a new MP4.
It uses OpenAI's open-source Whisper model with word-level timestamps. Clear speech in English transcribes very well; noisy audio and other languages benefit from the max-accuracy model in Listening settings (free, a 1.4 GB download once). Every word is click-to-edit before export, so the final file is exactly what you approve.
No. The model downloads into your browser once (about 190 MB with a graphics chip, 80 MB without, then cached), then everything runs locally. Your file never leaves your device, which you can verify in the network tab.
37. It listens first and names the language it hears, and you can change it in one click, which helps with accented or mixed speech.
What it is: a browser tool that burns animated word-by-word captions into a talking video, or cuts it to its best 30 or 60 seconds.
Price: free with every feature, for as many videos as you like. The first two carry no mark; after that each carries a small burncaps.app credit, which Pro removes for $49 once. No subscription.
Privacy: the video never leaves your browser. The sound leaves only if you choose our speech service.
Files: MP4 or MOV up to ten minutes in; an MP4 with the captions burned in out. SRT, VTT, ASS and text files are free without limit.
Languages and styles: captions in the language spoken, twelve Indian languages heard on your device, translation into 37 languages, 20 caption styles.
Made by: Jordan Labs Ltd, UK company no. 17358646.
Against other tools: twelve caption tools compared, from the vendors' own pages.
