How it works

Live on your site in 10 minutes.

Three steps. Self-serve in about 10 minutes.

Add it to your site in two clicks

Drop a one-line snippet on your website and the chat widget goes live. No code beyond that, no Zapier, no plugins.

Tell Costello about your business

Drop in your services, prices, opening hours, and tone. Costello becomes a brand-voice receptionist your customers can't tell from a human.

Every lead is automatically handled

Costello qualifies the lead in 60 seconds and hands them your booking link so they can book themselves. You see a clean transcript in your dashboard. You take it from there.

What you get

Everything a receptionist does.
Starting free.

Always on, 24/7

Right there on your website, replying to every visitor in under 60 seconds, every hour of every day. Sundays, bank holidays, the night before Christmas — handled.

Qualification on every lead

Asks the questions you choose — what they need, budget, timing — so every lead is qualified before they ever reach your booking page. No time wasted on enquiries that were never going to book.

Sounds like a real human

Pick the personality and even name your assistant — friendly, professional, premium, whatever fits your brand. Edit any pillar at any time and the change goes live instantly.

Routes the awkward stuff to you

Complaints, complex requests, anything off-menu — whatever genuinely needs a human gets escalated to your inbox immediately. No clumsy bot guessing at things it shouldn't.

Start for FREE

50 messages a month, forever. Most small businesses never leave it. When you outgrow it, upgrade in two clicks. No credit card to start, no contracts, no overage charges.

Watch your analytics

A clean dashboard for every lead: who messaged, what they asked, whether they qualified, and where they dropped off. Edit any answer, flip the kill switch, or upgrade your plan from the same place.

From the founder

It started with my mum's salon.

I'm Owen — a 29-year-old ex-Rolls-Royce engineer who now helps small businesses use AI to take the stress out of running things.

I'd watch my mum grind until 7pm most evenings — payroll, socials, replying to message after message. So I built her an AI assistant to take the busywork off her plate. It gave her back over 10 hours a week.

Word spread. Soon I was building the same thing for businesses all over — and one complaint came up everywhere: owners were sick of answering the same questionsall day long. That's why I'm giving Costello away for free — so you can stop replying to every bloody message and get back to growing the business.
