About Hartmann
AI-powered English learning for everyone, everywhere.
Hartmann was built to solve a simple problem: learning English is hard, expensive, and often inaccessible. Traditional apps teach vocabulary in isolation. Tutors are expensive. Textbooks are outdated.
We built Hartmann to be different — an adaptive AI coach that analyzes the phrases you actually use, explains your mistakes in context, and helps you sound natural in real conversations.
Whether you're preparing for TOEFL, improving your professional English, or just want to communicate better with family abroad, Hartmann meets you where you are.
Our mission
Make fluent English achievable for every motivated learner, regardless of budget or location.
