Reviewers mostly praise Preply for what happens in lessons: a big tutor selection, easy filtering and scheduling, personalized teaching, and visible progress in speaking confidence and fluency. Many also like the built-in classroom, notes, materials, and AI lesson insights. The main complaints are not about tutors but about the platform’s policies and support: recurring billing, expiring lesson packages, refund disputes, slow or inconsistent customer service, and occasional tutor reliability or calendar issues. Overall, people like learning on Preply but are wary of payment and support problems.
