I renamed the project to EigoPropo.
I’m building an AI tool for non-native freelance web developers
to generate client-ready English proposals in one click.
I’ve put together a Notion LP with a short 30-second demo👇

What I learned from 5 paid usability tests for EigoPropo 👇
• Users don’t know what to do next
• They’re unsure if their setup was saved
• They think job descriptions need rewriting
The issue was unclear copy, not missing features.

Building EigoPropo (AI proposal generator for non-native English freelancers).
This week: running 5 paid usability tests to improve the first-time flow (login → profile → generate)
and validate English quality + tone switching.
I’ll share the top 3 fixes next!

Two hours later:
Why do tiny layout tweaks always turn into boss fights?
Anyway, it looks perfect now.

I built an LP for my new tool, and here’s the funny part:
I keep telling everyone, “AI writes proposals in minutes,”
but the layout, the flow, and the wireframes?
Yeah… all of that was still made the old-fashioned way by one very analog human — me. 😇

Five hours of “requirement definition” later — still nothing decided.
Client confused. Me confused.
Maybe that was the requirement.
