Viral-Style AI Captions SaaS
Sell creators a simple AI captions tool with viral styles at a low monthly price.
In plain English
AutoSubtitles, a team in the UK, sells creators a simple tool for captions with the look of popular short videos. You upload a clip, the speech is written out, and styled words are drawn on the picture, with many languages and custom fonts, on a screen that stays to one simple view. Creators pay a low monthly price because captioning by hand is slow and plain text struggles to hold attention. The AI does almost all of the listening and the caption drawing, and billing runs on its own. The team still designs the caption looks, markets the tool, and answers support questions.
