Real-time call and message translation in one messenger
Chats, voice messages and calls in your own language: AiThao translates both ways. Chats are end-to-end encrypted, and translation can be switched off.
Speech in 96 languages: 91 with the translation spoken aloud, 5 with subtitles. Translation starts only when both of you agree.

A real-life example
How it works in real life
No complicated setup. You just call and talk — each of you hears the other in your own language.
Step 1 · Speech
You speak your language
Talk into the phone naturally, as on any call. AiThao recognises your speech during the conversation.
Step 2 · Translation
Speech translation
A cloud AI service translates what was said and voices the translation in a natural voice.
Step 3 · Voice
They hear the translation
The other person hears speech in their own language — nothing to read.
