Everyone's seen the bad version: a chat bubble that knows nothing, answers nothing, and ends every exchange with 'please call our team'. That's not an assistant, it's an obstacle with branding.
A useful assistant knows three things. It knows your business — services, hours, process, the questions your staff answer forty times a week. It knows your systems — live stock, bookings, order status — so it can answer with facts, not brochure copy. And it knows its limits — what it must never say, enforced in code on the server, not politely requested in a prompt.
That last one matters more than people think. We've built assistants for regulated firms where quoting a number could be a compliance breach. The guardrail isn't 'the AI has been asked nicely' — replies are checked server-side and anything non-compliant physically cannot be sent.
Done right, an assistant is the best salesperson you have: it never sleeps, it never forgets a fact, and it captures the lead at 11pm on a Sunday when your competitor's phone is ringing out. Every site we build ships with one as standard.
