Practice languages with AI through real-life scenes — ordering coffee in Buenos Aires, checking into a hotel in Rome, making small talk at a dinner party. After every response, get feedback on grammar, naturalness, and how clearly you'd be understood. Track your fluency with a chess-style ELO rating system — peer-reviewed to correlate 0.90 with CEFR levels. Spanish, French, and Italian. Available on web and iPhone.







Hey PH!
Origin story: I've been trying to learn Spanish to have real conversations with people in my life who don't speak English. And I kept hitting the same wall. Specific moment, specific question, I'd fumble and often fail.
I didn't need perfect grammar. It was the ability to engage — to get my thoughts across, to actually be in the conversation. The dinner small talk. The basic check-ins. The recurring questions you'll be asked again next week.
What I wanted was a way to replay those — or pre-practice the ones I knew were coming. Open-ended AI chat didn't fix it; you can dodge anything you don't know how to say. I wanted structure. Specific goals. Real feedback per response.
So Dialog Engine: each scene has checkpoints (greet, introduce yourself, ask about their week, etc.). You respond, get feedback line by line on grammar, naturalness, and clarity. Your fluency rating moves based on how you actually performed.
Spanish, French, Italian. Just shipped on iPhone alongside web.
Would love your honest feedback — especially if you've tried other AI language apps and felt they missed the mark in a specific way.
