WhatsApp assistant that answers from your own documents

Customers ask on WhatsApp; an AI assistant answers from your price list, FAQs and policies, and hands the chat to a person when it is not sure.

Businesses answering the same customer questions on WhatsApp all day: timings, prices, delivery, documents needed.

How it runs · 7 steps

Starts whenA customer messages your WhatsApp Business number

  1. Step 1, WhatsApp: Customer asks a question. Passes on: “Do you deliver to Thane?”.
  2. Step 2, n8n: Finds the matching parts of your documents. Passes on: Top passages from your FAQ and price list.
  3. Step 3, AI model: AI writes an answer from those passages only. Passes on: Answer + the document it came from.
  4. Step 4, n8n: Checks how sure it is. Passes on: Sure: reply · not sure: hand over.
  5. Step 5, WhatsApp: Replies to the customer. Passes on: Answer in the chat, in seconds.
  6. Step 6, Your team: Not sure? Hands the chat to your team. Passes on: Alert: question + chat so far.
  7. Step 7, Google Sheets: Logs every question and answer. Passes on: Row: question, answer, handed over?.
  8. Result: Routine questions answered at any hour; hard ones reach a person with the context.

Before and after.

Before · by hand

The same ten questions arrive on WhatsApp every day, the answer depends on who replies, and messages after 7 pm wait until morning.

After · once it runs

Routine questions get an answer at any hour, taken only from your documents, and anything it cannot answer reaches your team with the chat attached. Typically gives back 1–2 hours a day for a team answering 50 or more chats a day.

Time savings are typical figures for the size of business described, not a promise. Yours depend on your volumes.

How we build it

Built when you order, in about 7 working days.

  1. 01

    You order

    Send the form with this automation named. We reply within one working day with what we need from you and how to pay.

  2. 02

    We connect your accounts

    You give us access to the apps under ‘What you provide’. We build the workflow in your n8n account and connect each app.

  3. 03

    We test it with your data

    We run it on real examples from your business, fix anything that does not fit, and show you the results.

  4. 04

    Handover

    You get the written guide and it keeps running. Typically 7 working days from access to handover, then 30 days of fixes.

Questions buyers ask

+Is it ready to download?

No. Nothing is pre-installed. When you order, we build this workflow in your own account, connect your apps, test it with your data and hand it over, typically 7 working days after we have your access.

+What else will I pay for?

Meta's WhatsApp pricing applies; replies to a customer who wrote to you first are currently not charged. The AI provider bills per use, and the search index has free tiers that suit most small businesses. n8n is free to self-host on your own server; n8n Cloud has its own monthly plans. You pay those providers directly, not us.

+Can you host it for us instead?

Yes, with the optional Care plan: ₹999 a month for one automation, or ₹1,999 for up to five or any one pack ($29 and $49 outside India). We run n8n for you, keep your app connections in n8n's encrypted credential store, fix failed runs and renew expiring connections. Cancel any time and we move the workflow into your own n8n account.

+Can you adjust it to how we work?

Small changes that keep the same flow, such as message wording, fields, timings or who gets alerted, are part of setup. Anything that adds apps or steps is quoted before we start, and bigger builds are our custom automation service.

+What happens after the 30 days?

It keeps running in your account; it does not stop if you stop working with us. Fixes or changes after the 30 days are quoted when you need them.

+Who can see our data?

The workflow runs in your own account, so your data moves between your own apps. We need access while we set it up and during the 30 days of fixes; you can remove that access whenever you like. On the Care plan it runs in n8n on our server instead: your data passes through it on its way between your apps, and your app connections are stored encrypted.

+Can it run on Make or Zapier instead?

This one we build on n8n only, because its steps need what n8n does well and the others do not, or not at the same cost.

+Will it make things up?

It is told to answer only from your documents and to hand over when it cannot find the answer. We test it with your real questions before handover, and every answer is logged so you can check it.

Want this one, or something a little different?

If this is what you need, fill in the form and we will set it up for you. If it is not quite right, we build custom automations too. Tell us what you need.
