Miaoyu 妙语

WeChat reply assistant for Windows

Not sure what to say?
Start with Miaoyu.

Miaoyu sits beside WeChat on Windows and uses the visible conversation and your draft to suggest three replies. Make it warmer, firmer or more direct, then keep refining it in your own words. It learns your local writing preferences, supports Cantonese and five customer-service languages, and leaves the final send to you.

01

Beside the chat you are in

Turn on window following, draft sync and conversation reading to try importing the current WeChat draft and recent visible text. Use it mid-sentence or when you have no reply in mind. If detection fails, copy text and import it manually.

Three options. Keep refining.

Choose a considerate rewrite, a light polish or playful wording. Each round offers three drafts that appear progressively. Say “less formal” or “more assertive” to refine them. The aim is to express your position, not flatter everyone.

Your voice, and preferences for each chat

Messages identified as yours can become local style samples: sentence length, filler words, punctuation and emoji habits. Save names, context and feedback for each chat. You can view or clear local style, contact and brand-text records.

Understand before replying

Optional automatic analysis estimates mood, urgency, relationship tone and what the other person wants. It uses no credits, up to 400 times per account daily, but service limits still apply. Conversation members and above get subtext and wording to avoid. Mood estimates can discourage joking; automatic analysis can be disabled.

Check the tone, then plan ahead

Conversation members and above can check for blame, accusation or excessive deference and see alternative wording. For requests, refusals and negotiations, expand possible responses and suggestions for your next move.

Cantonese and five service languages

Rewrite in colloquial Cantonese with simplified or traditional characters. Customer Service Pro turns a Chinese brief into Indonesian, Vietnamese, Thai, Malay or English, using local brand phrases and a Chinese back-translation. It helps with wording; it does not operate seller dashboards.

07

Replace a draft. You still send it.

Copy a chosen reply or replace the WeChat draft, with a 10-second undo window. Miaoyu never presses Send. Check names, times, amounts and promises yourself. Fact review runs when needed and its warnings do not block your choice.

What it can’t do yet

Better you know now than after you install it.

  • Windows x64 only, with a Simplified Chinese interface. No macOS, mobile app or browser-based chat assistant.
  • Compatibility varies by WeChat version. It reads accessible visible text, not the full chat database, voice notes, images or videos.
  • AI needs internet access, an account and allowance. Plan, account and service limits apply; there is no unlimited or offline generation.
  • Replies and interpretations can be wrong. Review names, times, numbers and promises before sending.
  • Style profiles, chat preferences and brand text do not sync automatically between devices.
  • It does not send messages or run TikTok Shop or Shopee. Miaoyu is not officially affiliated with those platforms or WeChat.

FAQ

Can it read my WeChat conversation?

It can try reading recent text visible in the current window. Results depend on WeChat version, window state and permissions. It does not read the entire WeChat database. Copy text and import it manually if detection fails.

Will it send messages for me?

No. You choose, copy or replace the draft, then send it yourself. Replacement has a 10-second undo window, with checks when the chat or your draft has changed.

Does considerate wording just mean being overly polite?

The aim is to keep your position and meaning while making it clearer. Ask for a firmer or more direct reply and keep refining. Suggestions and mood estimates can still miss the point.

Where do my style and chats go?

Style, chat preferences and brand text are encrypted locally per account and can be viewed or cleared. Drafts, recent text and style summaries needed for generation or automatic analysis go through Miaoyu servers for cloud processing. Automatic analysis can be disabled. Details: https://miaoyu.app/privacy .

How do credits work?

Three drafts in one full round cost 1 credit; refinements are a new round. That round’s optional fact review adds no extra credit charge. Automatic intent analysis uses no credits, up to 400 times daily, subject to usage limits. Daily membership credits reset at 00:00 Beijing time without rollover. Failures before output are refunded; partial output or disconnections follow the published billing rules.

Monthly or one-time 30-day access?

Monthly plans cost less and renew automatically. Use Manage / Cancel subscription in your account to stop future renewal. One-time 30-day access costs slightly more and never renews automatically. Cancellation does not itself mean a refund. Checkout shows the final amount and currency.

Can I pay with Alipay, WeChat Pay or local currency?

Stripe offers payment methods and currencies according to region and order eligibility. Alipay and WeChat Pay are mainly for eligible one-time purchases such as 30-day access or top-ups, not every region or order. Recurring payment options are shown at checkout.

How do I get help?
