An AI Tutor That Actually Knows You

Most language apps teach everyone the same lessons. Lerno doesn't. Tell it your interests, and AI builds a weekly curriculum around them - movies, travel, cooking, whatever you care about. Every mistake gets explained with the grammar rule. A Practice Room lets you chat with an AI tutor 24/7. And every week, the whole plan rebuilds based on what you've mastered and what still needs work. French and Spanish. 7-day free trial, no credit card.





Hey everyone!
I built Lerno because I had a simple frustration: every language app I tried taught everyone the exact same thing.
I wanted to learn French. But I don't care about farm animals or classroom furniture. I care about cinema, travel, and food. Why couldn't my lessons reflect that?
So I built something different. Lerno asks what you're into during onboarding (movies, cooking, sports, travel, business, whatever) and then AI generates your entire weekly curriculum around those interests. Every vocabulary set, every grammar example, every practice scenario connects to things you'd actually want to talk about.
A few things I'm proud of:
- Your interests shape the content. Tell us you love travel, and your vocabulary comes from airports and hotels. Into cinema? You learn through film conversations. No two users get the same lessons.
AI rebuilds your plan every week. It's not a fixed path. Every week, AI looks at what you struggled with, what you've mastered, and what your goals are. Then generates a completely fresh curriculum.
- Mistakes become lessons, not dead ends. When you conjugate a verb wrong, you see the grammar rule, the correct form, and why it works that way.
- A conversation partner that's always available. The Practice Room lets you chat with an AI tutor anytime. No scheduling, no judgment. It matches your level and corrects you gently mid-conversation.
- It gets smarter the more you use it. Weekly reviews feed into next week's plan. Skills you've nailed move to the background. Weak spots get more focus. The whole system adapts.
This is a solo project. I'm not a developer. I built it using AI coding tools (Lovable) and used Claude as my development and strategy partner. The whole stack is React, Supabase, and Gemini AI.
Currently supporting French and Spanish, with more languages coming based on demand.
I'd genuinely love to hear:
- What's your biggest frustration with language apps?
- Does the interest-based approach resonate with you?
- What would make you switch from what you're currently using?
