What Manus can do with your WhatsApp

Research from a request

A client asks for something on WhatsApp. Manus finds the message and does the research.

Reports from chats

Manus turns a month of group messages into a clean report or slide deck.

Lists from groups

Collect every lead, order or RSVP from a group into a sheet.

Add WhatSync to Manus

You sign in to WhatSync once. No API keys to paste. Check what you need above first.

  1. Add a custom MCP

    Open Connectors, choose Create, then Add MCP by URL. Name it WhatSync and paste the server URL.

    https://whatsync.app/api/mcp
  2. Sign in to WhatSync

    Finish the sign-in with Google or your email. Then ask Manus which WhatsApp account it is connected to, to check it worked.

  3. Link your WhatsApp

    Open your WhatSync dashboard and link your personal WhatsApp from Linked devices on your phone, or connect the WhatsApp Business API. If you ask your agent something first, it replies with a sign-in link that works for 15 minutes.

  4. Choose what it can see

    On the What's saved page, enable message saving, pick the groups to include and keep any person out. Groups stay off until you tick them. The agent can read permitted messages saved since you enabled saving; linking does not import your entire WhatsApp history.

Things to ask Manus

Copy one, change the names, and try it.

  • Use WhatSync. Read what Riya asked for in our chat and make the comparison she wants.

  • Make a report of every customer complaint in the Support group this month, grouped by topic.

  • Collect every RSVP from the Wedding group into a sheet with names and counts.

Good to know

You choose which chats are saved, and you can unlink WhatsApp from your phone at any time. How we handle your data.

  • Manus works through long tasks on its own. If you cannot make it ask before each send, ask it for drafts only and check what it did after each task.
  • Sends are real WhatsApp messages and run when your AI app allows the tool call. Keep send tools on manual approval and review the recipient and text. Asking the agent to wait is not an enforced approval setting.
  • Use the Business API for campaigns to customers who opted in. The Business API does not permit unsolicited messages. Linked personal accounts can be restricted for violating WhatsApp's rules.
  • Search covers saved message text, file names and captions. WhatSync does not index document contents, transcribe voice notes or read text inside images. A download link is available only when WhatSync saved the file.
  • Group searches and replies require a linked personal WhatsApp. WhatsApp Business API tools work with customer conversations, templates and campaigns.
  • An unanswered conversation means its latest saved message in the checked period is incoming. It is a follow-up signal, not proof that a question is unanswered or that you owe a reply.

Questions

Something else? Ask us.

Can Manus use WhatsApp?

Yes. Add WhatSync as a custom MCP by URL and sign in. Manus then gets tools to search your saved chats and, if you allow it, send messages.

Will Manus message people without asking?

An allowed send tool call sends right away. Telling it to ask first is not a hard rule. To be safe, ask it for drafts only and send them yourself.

Do I need to install anything?

Not for WhatSync. We run the server for you. You only need the AI app itself. Your WhatsApp keeps working on your phone as normal.

Does it work with the WhatsApp Business API?

Yes. Connect a number through Meta and Manus can check and create templates, send approved templates, and run campaigns to customers who opted in. Meta reviews every template and charges per message, depending on the country and message type. See WhatsApp Business API.

Is WhatSync made by Manus?

No. WhatSync is made by Appstronauts. It is not made by, affiliated with or endorsed by Manus, WhatsApp or Meta.

How much does it cost?

See the pricing page for the current plans.
