MiaoYan: AI Reply Keyboard

Chainfun

About this app

MiaoYan is an AI-powered keyboard that helps you find the right words in seconds.

Stuck on how to reply? Tap once. MiaoYan reads the conversation you are looking at, understands the tone, and drafts a reply you can send as-is or edit in one tap. It works inside any app that accepts text input.

WHAT YOU CAN DO

• One-tap AI replies
Generate a natural, context-aware reply without leaving the chat you are in.

• Choose a tone that fits
Built-in scenes let you switch register instantly: high-EQ, warm, humorous, playful, gentle, or straight-to-business.

• Personas
Pick or create a persona so the replies sound like you, not like a robot.

• Rewrite and polish
Turn a rough draft into something clearer, friendlier or more professional before you hit send.

• Screen understanding
Let MiaoYan look at the conversation on screen so its suggestions match what is actually being discussed. Screen access is opt-in and can be revoked at any time.

• Voice input
Speak instead of typing when your hands are busy. Uses your phone's built-in speech recognition; we never receive your audio.

• Your own knowledge base
Upload documents such as product sheets, price lists or FAQs, and MiaoYan will ground its answers in your material instead of guessing.

• Sales workspace
Keep notes on the people you talk to and get follow-up, objection-handling and closing suggestions built around that context.

• Full-featured typing
English, Vietnamese and Pinyin layouts, picked automatically from your device language, plus everything else you expect from a daily-driver keyboard.

TRY IT WITHOUT AN ACCOUNT
You get free AI replies as a guest: no sign-up, no email, no phone number. Sign in only when you want to keep your settings, personas and documents across devices.

PRIVACY
MiaoYan does not log what you type. Text is sent to our AI service only when you explicitly ask for a suggestion, and screen capture only runs while you have granted it and turned it on. If you sign in, your reply history and contact notes are saved to your account so you can pick up where you left off. Delete any of it, or your whole account, at any time. We never sell your data.
