I'm building a Figma plugin to automate design QA — looking for feedback

Hey IH community,

I have an idea for a Figma plugin called Coherence that I want to build. Here is the problem I am trying to solve:

When designers finish a project with 50+ screens, they have to manually check for typos (like "Cance" instead of "Cancel"), make sure they did not mix "Sign In" and "Log In," verify that error messages match the brand tone, and confirm buttons have proper accessibility labels for screen readers. It is painful and error-prone.

My idea: a plugin that automatically checks your Figma file for typos, consistency, tone, and accessibility — all in one click.
I built a waitlist to see if others feel this pain too:

If you are a designer or developer, would this be useful to you? What other checks would you want?
Still in the idea/validation phase — no plugin built yet. Just want to know if the problem is real before I invest time building it.
