Zalo chat —
instantly in your language
The extension layers on top of chat.zalo.me. Incoming messages are translated right under the original; you type in your native language — your contact receives Vietnamese. No copy-pasting into Google Translate, no tab switching.
Real-time
The extension layers on top of the native Zalo client. Networking stays with Zalo — we only handle the translation.
Six partner languages
VI, EN, ZH, JA, KO, FR. Each chat has its own language setting — from a one-time visitor to your regular partner.
Local cache
Translations are stored on your device, encrypted with AES-GCM. Reopening a chat pulls them up instantly.
Glossary
Personal forced translations for names and terms. Map "Anh Tuấn → brother Tuan" once — it applies everywhere.
Claude AI
Translation runs on Claude Haiku 4.5 — preserves tone, idioms, and emoji while keeping conversation context.
Privacy
Message bodies are not stored on the server. Only metadata for billing and quotas remains in the database.
