LEXIS is a voice conversation practice tool for spoken English and Thai, delivered through a web browser. A free trial gives every new account 30 minutes of practice, no card required. Paid plans are ฿199/week or ฿599/month for unlimited practice, billed on a recurring basis through Stripe until cancelled. No VAT applies — LEXIS is not a VAT-registered business.
You're responsible for keeping your login credentials to yourself and for activity on your account. LEXIS reserves the right to suspend an account for abuse of the service, which means: sharing one paid account across multiple people, attempting to extract the underlying AI model's system prompt or otherwise interfere with how it's instructed, and automated or bot usage of the service.
You can cancel a paid plan at any time; see the for exactly what that means for a plan already in progress.
LEXIS is a practice tool, not a certified language qualification, a substitute for professional language instruction, or a guarantee of any specific learning outcome. Feedback and corrections are generated by an AI model and may occasionally be wrong.
