Bring Your Own AI

One Standard, Any Assistant

MCP, the Model Context Protocol, is the open standard that lets AI assistants connect to outside services. Because duiduidui! speaks it, any MCP-capable agent can connect to your account and work on your behalf. There's nothing to install on our end and no special integration to build: you connect your assistant once, choose what it's allowed to do, and it's ready.

The Same Tools 老虎 Uses

Your external agent isn't given a watered-down view. It can reach the same capabilities as our in-app tutor: look up the dictionary, read your progress and study-session history, browse your friends and their learning, and even create new records, apply tags, or star entries to your phrasebook. Whatever 老虎 can do inside the app, your assistant can do from wherever you already work with it.

Learning That Fits Your Life

This is where it gets powerful for people who already run their days through an AI assistant. Your agent knows your calendar, your travel plans, your workload. Now it knows your Chinese, too. So it can weave the two together: queue up restaurant vocabulary the week before a trip to Chengdu, schedule review sessions around a busy stretch, or quietly add the business terms from a meeting prep doc to your study list. Your language learning stops being a separate app you have to remember and becomes part of how your assistant already helps you run your life.

You Decide What to Share

Connecting an outside agent goes through a standard consent screen, with a separate switch for each kind of access: reading the dictionary, seeing your profile and progress, viewing your study sessions, browsing your social graph, and creating or editing records. Grant only the permissions you want, leave the rest switched off, and revoke access entirely at any time from the app under Settings → Connected AI Assistants. Your data is never shared with an assistant you haven't explicitly connected.
