Summarize the noise and chat across languages in real time — without a single message leaving your laptop.
WACAO runs entirely on Chrome's built-in AI (Gemini Nano). No cloud, no account, no API keys — and no network call after setup. The AI reads your chats right where they live.
No bloated feature list — just the parts of WhatsApp that actually eat your time.
Built for Airbnb hosts and anyone chatting across a language barrier. Incoming messages are translated for you, and your replies go out in their language — right inside WhatsApp Web.
