Sai is a language tutor you talk to. Put on headphones and hold a real spoken conversation, at your level, in Spanish or eight other languages.

About Sai

Most learning apps teach you to recognise words. People still freeze when someone actually speaks to them. Sai is the speaking part: every session is a conversation with Sai, a small listening bot in headphones, not a script to repeat. Beginners get short lines and help in English; as they improve, Sai stays in the language.

Mistakes are fixed the way a good teacher does it, by saying the line back correctly and carrying on, so nobody feels judged. Sai also remembers you. After each call it notes your trip, your family and the words you struggled with, and picks up from there next time, so a learner never starts from zero.

Sai is deliberately calm. Progress is the words you have actually used in conversation and the talks you have had.
