LUMI FOR ORGANIZATIONS
Internal communication and business apps in an environment you govern
Lumi combines messaging with a path to data residency and embedded business apps. Private deployment can be evaluated against each organization’s infrastructure and governance needs.
Data residency
Agree on service location, storage, backup and access boundaries as part of the deployment plan.
Security governance
Design encryption, access controls and device management together with operating responsibilities and third-party data flows.
App expansion
Use the embedded H5 app capability to connect business tools; design identity and data exchange for each integration.
Private deployment scope, data residency and security controls depend on the assessed design and contract. No deployment can guarantee absolute security.
What is Lumi?
Lumi is a social messaging app: 1-on-1 chat, group chat, @mentions, read receipts, paired with automatic per-message translation so cross-language conversations don't need copy-pasting into a separate tool. Beyond chat, Lumi has a moments-style "Plaza" feed, stickers, wallet top-ups and social gifting, an AI companion built on a real 3D model, and smooth voice/video calling. iOS, macOS and Android are all natively built, matching the feel of mainstream social apps.
What actually makes it different
Not another "AI-powered" buzzword — these are real, shipped
Translation happens on your phone, not a server
On iOS 17+, translation runs through Apple's on-device translation framework — no server round-trip, no per-call API cost, and better privacy. Language is auto-detected, and translation is skipped automatically if it already matches your display language.
Chat bubbles can render actual formulas
LaTeX math and chemistry notation (mhchem), plus Markdown formatting — handy for students and anyone sharing technical content in chat.
The AI companion isn't a support bot
A companion built on a real 3D model, with streaming conversation, TTS voice, and real-time lip-sync animation — built for entertainment and companionship, not customer support.
Every platform is built natively
iOS, macOS and Android each have their own native implementation — not a wrapped web view — matching the feel and responsiveness of mainstream social apps.

Frequently Asked Questions
How is Lumi different from WeChat or WhatsApp?
Lumi sits in the same category as WeChat and WhatsApp — a social messaging app for everyday use. What sets it apart is real-time per-message translation (mostly running on-device, no server round-trip), chat bubbles that can render math/chemistry formulas, and an AI companion built on a real 3D model.
Does the translation feature need an internet connection?
On iOS 17+, translation runs through Apple's on-device translation framework and doesn't need a network connection or a server round-trip. On iOS 16 and Android/Web, translation goes through a backend translation proxy. The app auto-detects each message's language and skips translation automatically when it already matches your display language.
Which platforms does Lumi support?
Lumi is currently available on the App Store (iOS), Mac App Store (macOS) and Google Play (Android) — check each store listing for the current version.
