Frequently Asked Questions
More about Lumi
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.
Is wallet top-up and withdrawal safe?
Lumi's wallet connects to mainstream compliant payment channels and crypto top-ups, and withdrawals go through a risk-control holding period. Check the in-app listing for the current payment methods and rules.
What is the AI companion? How is it different from a support chatbot?
The AI companion is a chat feature built on a real 3D model, with streaming conversation, synthesized voice and real-time lip-sync animation — it's built for entertainment and companionship, not for resolving support issues like a customer-service bot.
