    Our engine, your own AI key, your own code, or Meta’s AI through a connector — each answers from the one source you keep current.

How it finds answers

Answers from your shelf, not a guess.

Put your documents on one shelf. When a customer asks, the assistant pulls the few passages that answer it, and writes its reply from only what they say.

A customer asks Meher Bakes, on WhatsApp

Do you deliver to Baner on a Sunday? How much?

Yes! Baner is in our Zone 2, so delivery is ₹60. On Sundays we deliver between 11 am and 6 pm. Shall I book you a slot?

  • Found by meaning and by exact words

    A question about “Sunday” finds the note that says “weekends”, and a product code still finds itself.

  • It drafts; your team sends

    Today the assistant writes its reply into the WhatsApp conversation as a draft, and a teammate sends, edits or dismisses it. Fully automatic replies are in a pilot.

  • No page, no answer

    It is told to answer only from your shelf. When the shelf doesn’t cover a question, it says so and offers to check with your team.

Five plugs

Five plugs, one source of truth.

Change a price once and every plug answers with the new one. Here is what each one is, and who gets it.

    Zapuu AI

    Live

    Growth and above

    WA.cr’s own managed AI. No key to find and nothing to configure: create an assistant, put your knowledge on its shelf, and it starts drafting replies.

    • Included in your plan; what it uses is metered on your wallet.
    • One assistant on Growth, five on Scale, as many as you need on Enterprise.
    • Pick fast or smart answers for each assistant.

    Your own AI key

    Live

    Scale and above

    Already pay for an AI provider? Connect your OpenAI, Anthropic or Google Gemini key and your assistants answer through your own account, from the same knowledge.

    • Model usage bills to your own provider account.
    • Keys are stored encrypted and never shown back, not even to you.
  • 3

    API

    Live

    Scale and above

    Your own app, chatbot or voice assistant searches the same knowledge over HTTPS, so you never keep a second copy of your answers that drifts.

    • One call: POST /v1/knowledge/search, with a key that carries the ai:read scope.
    • Give the key only that scope and it can read your knowledge, nothing else. Revoke it and access stops.

    MCP

    Live

    Scale and above

    Connect Claude, ChatGPT and other MCP clients to your workspace with a sign-in. They work with your messages, contacts, appointments, forms and more.

    • The search_knowledge tool reads the same knowledge base your assistants answer from.
    • It needs the ai:read scope; a connection made before that scope was offered reconnects once.

    Meta Business Agent

    Live

    Every plan · connectors on Scale and above

    Meta’s own AI, replying on your WhatsApp number. On Scale and above a connector lets it call your systems’ APIs, the knowledge search above included.

    • Its own knowledge, skills and test panel, set up per number in WA.cr.
    How it works

  • One shelf behind every plug.

    Your knowledge lives in WA.cr, in your workspace. Plug something in, unplug it, swap it — the shelf stays put and stays current.

Check its work

Check the receipts before you send.

Try any question in the assistant’s test panel: each turn shows how many passages of your knowledge it read, which tools it called and what the turn cost, in rupees. In a live chat its reply waits as a draft until a teammate sends, edits or dismisses it.
