Hey Product Hunt! 👋

I'm excited to share RevisionMargin, a free tool built with AI to help freelance designers and web developers estimate project costs, account for revisions, and create clearer project quotes.

The idea came from a simple question: how can freelancers avoid doing extra work without getting paid for it?

RevisionMargin is currently a research beta, not a paid product. It supports English and Thai, requires no signup, and runs calculations directly in your browser.

I'd love your honest feedback:

Would you use something like this for your projects?
What would you change or improve?
What tools are you using today?

I'm especially interested in feedback from working freelancers. Your input will help determine what we should build next.

Thanks for checking it out!
