Customer Support Agent

I got tired of watching good inquiries go cold overnight. So I built an agent that reads every message, answers it properly from what the business actually knows, logs it, and wakes a human when it should not answer alone. It has been running live in Abuja since. It costs nothing a month to operate.

Who I built this for

If your customers ask the same questions all day, this is for you.

  • Car dealershipsDo you import? How long? How much? Same five questions, every day.
  • Clinics and hospitalsOpening hours, appointments, what you treat, what you charge.
  • SchoolsAdmission requirements, fees, term dates, forms.
  • Real estateIs it still available, what is the price, can I inspect it.
  • E-commerceWhere is my order, do you deliver here, what is the return policy.
  • Any service businessIf you answer the same message more than five times a week, it should not be you answering.

The problem

A serious buyer messages you at 11pm. You reply at noon the next day. He has already bought elsewhere.

That is the whole problem. Not laziness, just physics. One person cannot watch an inbox, a form and a phone at the same time, all night, every night. So inquiries sit. And an inquiry that sits is a sale that quietly leaves.

The usual answers are all expensive. Hire someone, and you pay a salary every month for coverage that still sleeps. Buy a support platform, and you pay hundreds of dollars a month for features built for companies with support departments. I wanted a third answer: something that never sleeps, knows the business properly, and costs nothing to keep running.

How it works

Five steps, no human in the middle.

  1. It listens.A message arrives by email or through the web form. The agent picks it up within minutes, around the clock.
  2. It checks itself.Duplicate inquiries inside a five minute window are caught, so nobody gets answered twice.
  3. It reads the business.The answer is drawn from a knowledge base you control: hours, services, pricing policy, FAQs. It also knows what time it is, so it tells the customer when to expect a human if the office is closed.
  4. It answers properly.Every question in the message gets addressed, signed in the business's name, with contact details and hours attached.
  5. It knows its limits.Anything urgent, angry, or outside what it knows gets flagged and escalated to a human instead of guessed at.

The receipts

Real messages, real replies, real logs.

Screenshots from the live system. Customer details are redacted where a real person's complaint appeared, but nothing about how the system behaves has been touched.

A customer email asking four questions at once about importing a car
One message, four questions. Do you import, can I trust the history, how long, how much. The kind of message that decides a sale.
The AI agent's full reply answering every question with business hours and contact details
The reply, minutes later. Every question answered, importation timeline included, business hours and contact attached, signed in the dealership's name.
The web form channel for customer support requests
A second door. Customers who would rather fill a form than write an email get the same agent and the same speed.
Inbox showing multiple messages tagged AutoReplied by the system
Tagged and handled. Every AutoReplied label is a message the agent closed on its own, across several inquiries at once.
Google Sheet logging every inquiry with timestamp, name, email and question
Nothing is lost. Every inquiry lands in a sheet with time, name, email and question. The playful names are my own stress tests, fired at it to see what it would do.
Sheet showing AI replies stored beside inquiries, with one row escalated to a human
This is the row I am proudest of. I sent it a furious message on purpose. It did not try to smooth it over. It marked the case urgent and escalated it to a human. Knowing when not to answer is the hard part.
The Google Docs knowledge base holding business hours, services and FAQs
The brain, in plain English. Hours, services, delivery, financing, FAQs. It is an ordinary document. If you can edit a doc, you can change what your agent knows.

Under the hood

For whoever wants to look.

Most people buying this do not care how it is written, and that is fine. But I would rather show the work than ask you to take my word for it. Three pieces of the actual running code.

Open the code
Code showing business hours logic
It knows what time it is. Sunday, after hours, mid-Saturday. The reply changes so nobody is promised something at 2am.
Code showing duplicate inquiry detection
It does not repeat itself. Same person, same five minutes, matched by email or phone. One answer, not four.
Code showing the message queue system
It queues. Everything is written to a queue with channel and status before processing, so a burst of traffic does not drop anyone.

What it replaces

Questions people actually ask me

Before you ask, here is what I usually say.

How fast does it really reply?

Under five minutes, day or night. Most replies land in about a minute. The five is me leaving room, not me hedging.

How is it free to run?

It runs on Google Apps Script inside your own Google account instead of a paid support platform, so there is no monthly platform fee. You pay me once to build it, then it is yours.

What happens when it does not know something?

It escalates. Anything urgent, angry or outside the knowledge base is flagged for a human instead of guessed at. I would rather it stay quiet than invent an answer about your business.

Which channels work today?

Email and web forms are live. Voice, WhatsApp automation and multi-language are custom builds, quoted separately.

Do I need to be technical?

No. The knowledge base is an ordinary Google Doc. If you can edit a document, you can change what your agent knows and says.

How long until it is running?

Live within 48 hours of you sending me your business information.

Is my customer data safe?

Everything stays inside your own Google account. No outside support company is holding your customer conversations.

What if I already use Zendesk or Intercom?

Then you already know the monthly bill. This does the front line of the same job for no monthly platform fee. Some people run both for a while before deciding.

Want this answering your customers by Friday?

Tell me what your business does and what people keep asking you. I will tell you honestly whether this fits, and what it would cost.
