Does an AI tutor actually work?+
The thing that builds fluency is speaking often and getting corrected right away - which is exactly what's hard to get from a class once a week. Katie gives you that on every sentence, every day, so the reps add up fast. Learners typically notice their grammar and word choice improving within a few weeks of daily practice.
Is Katie AI for me?+
If you already know English but want to sound fluent, confident and natural - for work, travel, interviews or daily life - then yes. Katie meets you at your level, whether you're rebuilding confidence or polishing the last 10%.
Is there a practice limit?+
No. Unlimited conversations, 24/7.
