The tutor who remembers what you keep getting wrong
Every piece you write comes back marked up like a tutor's red pen — word by word, with the why. Your recurring weak spots are surfaced, so you can see exactly what to work on. Correction is minute one. The file is the point.
Minute one. Month two.
Correction the second you write. A file that grows the longer you stay. Both below are real, unedited sessions from the app.
A real Spanish session — marked up word by word, with the why.
A real Greek file — the weak spots that keep recurring, flagged across the last 17 sessions.
Every session is marked up like a tutor would. Every mistake goes in the file.
How it works
A prompt at your level, or your own piece. Start from a suggestion or paste in something you're already working on.
Every mistake gets a category, a severity, the reason why, and a better alternative. Like a tutor's red pen, in seconds.
Your recurring weak spots surfaced with the reasoning, and your level trajectory plotted — so you can see exactly what to work on. Targeted drills from your own mistakes — coming soon.
"I built this because I kept making the same mistakes in French and Greek and nothing was tracking the pattern. I use it every day on my own French — I'm chasing DALF C1 with it."
— George, founder
"I've spoken German for nearly 40 years, and within an hour of using this I purchased a year's subscription — it pinpointed repeated minor error patterns I didn't know I had. I'm grateful for a tool that can so quickly find the subtle trouble spots in a language that already feels almost native to me."

"Fluency Write is amazing for getting practice writing in another language. The prompts make it easy to just start writing, and the detailed feedback is exactly what I need to strengthen my ability to communicate in Italian. My favorite part is saving feedback in the notebook for future review. Couldn't recommend enough!"
