Burn animated word-by-word captions into your TikTok videos, the format that holds attention when most viewers watch on mute. Free to use, no account, and your footage never leaves your device.
Caption a TikTok freeLive preview, rendered on this page by the same engine that burns your video.
Each word lights up as it is spoken, which is the pattern that holds attention in a fast feed. Twenty styles, all included, including the heavy outlined look and the keyword highlight most short-form creators use.
Your 9:16 video exports at the same size and framing you gave it. Captions are positioned with a slider so they sit clear of the TikTok interface at the bottom of the screen.
Export is a clean MP4 with the captions burned into the pixels, so they survive re-uploads and show for every viewer. Your first two videos carry no mark of ours at all.
Most caption apps charge every month because every video you upload runs on their GPU servers. Burncaps does the work on your own hardware, so free is not bait: every feature on every video, no watermark on your first two, and a small burncaps.app mark after that, or get Pro, $49 once, for unlimited videos with no mark, never a subscription.

Yes. The export is a standard vertical MP4, so the same file posts to TikTok, Instagram Reels and YouTube Shorts. Nothing in the tool is TikTok-specific beyond the caption styles creators favour there.
Yes. They are burned into the pixels rather than attached as a separate subtitle track, so they appear for every viewer on every platform, including people who have captions turned off.
Not on your first two videos: they are free with every feature and no branding of ours anywhere on the export. After that you can keep going free, and each video carries a small burncaps.app mark in the top corner; Pro, $49 once, gives unlimited videos with no mark.
No. Burncaps is a web page. The MP4 export is fastest in Chrome or Edge on a computer, and many phones export too; subtitle files work in most browsers, phones included.
It uses OpenAI's open-source Whisper model with word-level timing. Clear speech transcribes very well, and every word is click-to-edit before you export, so slang and brand names are quick to fix.
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.
