- Realtime messagingHow AiThao delivers messages the moment they are sent and still never loses one: an open WebSocket per app, a database written first, and catch-up for phones that were offline.
- End-to-end encryption, explainedHow AiThao uses the Signal Protocol: keys per device, a key that moves forward with every message, sender keys for groups, per-file keys and safety numbers.
- How calls workHow voice and video calls in AiThao travel: WebRTC, a media server AiThao runs itself, relays for difficult networks, and the per-call key behind end-to-end encryption.
- How live call translation worksWhat happens to your voice during a translated AiThao call: a translation worker joins the call, streams speech to cloud models, and plays back speech or subtitles.
- How message and voice translation worksHow AiThao translates chat messages in 92 languages and voice messages: decryption on your phone, a cloud translation model with a fallback, and nothing stored.
The parts, in one paragraph each
Messages travel over a connection each app keeps open to the server, so they arrive the moment they are sent. They are end-to-end encrypted with the Signal Protocol before they leave the phone. Calls use WebRTC through a media server AiThao runs itself. Translation is done by cloud speech and translation models, reached through AiThao’s own translation service.
Notifications go through the phone platform’s push service, with previews encrypted for your phone. Photos and files are encrypted on the phone and uploaded straight to object storage with a short-lived signed link.
What AiThao does not name
The pages name open standards and open-source software. They do not name the companies that provide cloud translation, speech, storage or relays: those change, and what matters to you is what each is allowed to receive, which the Security Center sets out.
Questions
Does translation run on my phone?
No. Translation always goes through cloud models; the phone records, encrypts, decrypts and plays, but does not translate.
Is AiThao open source?
No. It is built on open standards and open-source components such as the Signal Protocol and WebRTC.
