Burn animated word-by-word captions into your TikTok videos, the format that holds attention when most viewers watch on mute. Free and unlimited, 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. Ten styles, five free, including the heavy outlined look 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, with no watermark anywhere.
Caption apps charge every month because every video you upload runs on their GPU servers. Burncaps does the work on your own hardware, so the free tier is not bait: it is unlimited, permanently, with no watermark. Pro is a one-time £29 for the premium styles, 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.
No, and there never will be. The free tier is unlimited videos at any length with no branding of ours anywhere on your export.
No. Burncaps is a web page. For the MP4 export use Chrome or Edge on a computer; subtitle files work in most browsers including phones.
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.
