Bold viral captions, free and made in your browser
Heavy weight, hard outline, bright highlight. This is the look built for a phone held at arm’s length with the sound off — legible at a glance and difficult to scroll past.

How bold viral captions work
Weight and outline do the work. A thick stroke keeps the letters readable over any footage, so the caption never disappears into a bright frame or a busy background.
Nothing is uploaded
The transcription, the styling and the final render all run on your own machine. There is no server in the middle, no queue and no account — open the video, generate the captions, download the file.
You do not have to take that on trust: open the network tab in your browser while captions are generating and watch it stay empty.
Change anything you like
The style is a starting point. Font, size, colour, highlight, position and animation stay editable once it is applied, and every change is previewed on your own footage rather than on a stock clip.
Questions
Are bold viral captions free?
Yes. Every style is free, and free exports are unlimited at 480p with a small watermark. Paying once for a video removes the watermark and unlocks higher resolutions.
Do I need to sign up?
No. There is no account, and nothing is uploaded anywhere.
Can I export the subtitles as a file?
Yes — captions download as .srt or .vtt, as well as being burned into the video.
