Choose Katie AI if…
- You want a tutor that remembers your past conversations and your goals, so you never start from zero.
- You want a learning path built around your daily life, with phrases and vocabulary you will actually use, not a generic curriculum.
- You want to practise any time, without booking.
- You want unlimited practice, not a set number of minutes.
- You feel nervous speaking to a stranger and want to practise privately first.
Choose Cambly if…
- You want a real person to talk to.
- You want lesson recordings and a tutor who plans lessons.
- A human connection matters most to you.
Good to know before you choose
Cambly: Lessons are booked in advance with a tutor, so how much you can practise depends on your plan and the tutor's schedule.
Katie AI: Katie teaches English only, so it is not the pick if you are learning another language. It is built for people who already know some English, so complete beginners may want a beginner course first. If what you need most is someone to hold you accountable, or a teacher's judgement on your career or exam, a human tutor still wins.
Frequently asked questions
Is an AI tutor as good as a human tutor?
They do different jobs. A human tutor gives you a real person, accountability and a teacher's judgement. An AI tutor like Katie lets you practise as much as you want, any time, with a correction on every sentence and a learning path built around your life.
Does Katie AI remember previous conversations?
Yes. Katie remembers what you talked about before and what you want to learn, so it feels like talking to a person who knows you, not starting over with a new app each time. It uses that to choose topics that matter to you and to pick up where you left off.
