AI-powered coaching that adapts to your weak spots. Practice real exercises, earn XP, and watch your writing sharpen — lesson by lesson.
See how ProseAI spots weak writing and scores your rewrite — instantly.
Rewrite this sentence — cut it by at least 40%:
Duolingo proved that short daily practice beats long irregular sessions. We built the same loop for writing.
Each lesson shows you writing that buries its point, hedges its claim, or uses 40 words where 8 will do.
You fix it. No multiple choice — you actually write. That's what builds the muscle.
Gemini reads your version, names the technique you used (or missed), and scores your clarity in 3 sentences.
XP, streaks, leagues, and 25 achievement badges — all the Duolingo mechanics, tuned for writing.

"I spent years trying to write more clearly. Two weeks of daily ProseAI lessons and my manager noticed my emails had changed. The hedge-word exercises alone were worth it."
"The streak system got me. I'm on day 34 now. My writing score went from 52 to 81 and I can actually feel the difference when I'm writing proposals."
"8 cents per AI session is insane value. I was spending $30/month on Grammarly and getting spell-check. This actually teaches me to write better."
Five minutes. One lesson. One rewrite. That's the whole habit.
