Built a free calculator for AI video production costs — Runway, Kling, Luma

I kept underestimating my monthly AI video spend. The problem is that every platform has a different credit system and none of them map to the same thing.

So I built a simple calculator. No account, no email, just open it and get a number. It also shows GPU equivalent cost so you can compare SaaS vs self-hosting.

Built with vanilla JS and Shadow DOM — zero dependencies, loads instantly.

Happy to hear what other models people want added.
