SaiHi, under the hood.

SaiHi is voice-first translation for families who don't share a first language. You speak naturally, and everyone hears and reads the message in their own language. It works in one-on-one chats, family groups and push-to-talk walkie-talkie mode, with no reading required.

Pair the familyScan a QR code to join. No passwords, no setup.
Just talkRecord a voice message in your own language.
Everyone hears theirsEach listener hears the message in their language, in a natural voice, with the text alongside.
It cleans up after itselfMessages delete on a schedule unless someone saves them.

Meaning, not just words.

SaiHi's pipeline was tested on round trips (English to Tagalog and back) to make sure meaning survives, not just vocabulary. A fallback chain keeps messages flowing when a provider has trouble.
