TOOLS

Free tools

Small, free tools for planning AI dramas, films and ads. No sign-in; they run in your browser on the same data as our public pages.

AI video cost calculatorUSD and Katechon Arc credits for any clip, episode or series on 20 models, with a 30-episode drama preset from our own films.

Data behind the tools

The tools read the same checked data files as the rest of this site: the AI video price index (list prices quoted 2026-10-17), the model credit table that the Katechon Arc studio charges from, and the production records of the films we made. When the data is refreshed, the tools change with it.

For questions the tools do not answer, see the answers library, for example how much an AI short drama costs or the cheapest AI video model per second.
