How it works
Frequently asked questions
What is LEXIS?
LEXIS is a voice-based speaking practice tool for English and Thai. You have a real, spoken conversation with it over your microphone, and it replies in real time, the way a conversation partner would — not a chatbot you type into.
Who is LEXIS for?
Thai speakers who want to practice spoken English, and English speakers who want to practice spoken Thai — students, young professionals, and anyone preparing for interviews, travel, or work who wants low-pressure speaking practice without needing another person available.
Is LEXIS free to try?
Yes. New accounts get a free 30-minute trial — no card required. After that, LEXIS is ฿199/week or ฿599/month.
How is this different from a language exchange app?
There's no waiting for a partner to be online, no scheduling, and no awkwardness about correcting a stranger. LEXIS is available any time you are, and its whole job is to help you practice — not make small talk.
Can I interrupt LEXIS mid-sentence?
Yes — real conversations involve talking over each other sometimes, so you can jump in and interrupt LEXIS at any point, the same as you would with a person.
What happens to my voice recording?
Your microphone audio streams live to power the conversation and isn't saved as an audio file on LEXIS's own servers. After a session, LEXIS keeps only a short feedback summary (a confidence score and a few corrections) — never a transcript of what you said. See the full Privacy Policy for details.
