What a good assistant is for

A website assistant has one commercial job: turn a visitor with a question into an enquiry or a booking, at any hour, without frustrating them. Everything you evaluate should come back to that.

Must-haves

Capability Why it matters
Answers only from your approved information Prevents invented prices, promises and advice
Says clearly that it is AI Required for EU customers under the AI Act, and builds trust
Hands over to a person easily Urgent, sensitive or complex questions need people
Captures the enquiry properly Name, contact details, need and timing, sent to your CRM
Books the next step Calendar integration turns interest into an appointment
Speaks your clients' languages Especially for international or diaspora clients
Works on mobile and with a keyboard Most visitors are on phones; accessibility matters
Lets you read every conversation So you can improve answers and spot problems

Questions to ask any provider

  1. Where does the assistant get its answers, and how do we control what it says?
  2. What happens when it does not know the answer?
  3. How does a customer reach a person, and how fast?
  4. Where is conversation data stored, for how long, and is it used to train models?
  5. Is there a data processing agreement?
  6. Does it integrate with our CRM, calendar and messaging channels?
  7. Can we see and export every conversation?
  8. How is it labelled as AI?
  9. What does it cost as volume grows, and are there limits?
  10. If we leave, what do we keep?

Red flags

  • Promises that it "never makes mistakes" or replaces your team entirely.
  • No way to restrict it to your approved information.
  • Conversations stored somewhere you cannot see or export.
  • No clear AI label, or a fake human name and photo.
  • A widget that blocks the page on mobile or traps keyboard users.
  • Pricing that hides the cost of the volume you will actually have.

How to measure it

Measure What good looks like
Conversations started Steady, without annoying pop-ups
Enquiries captured from chat The main success metric
Bookings made from chat Proves it moves people forward
Handover rate and speed Handovers happen quickly when needed
Out-of-hours enquiries captured Shows value you were losing before
Conversations reviewed and answers improved Monthly, at least in the first months

Launch plan

  1. Write down the 30 to 50 questions customers really ask, with approved answers.
  2. Decide what the assistant must never answer, and where it hands over.
  3. Connect the CRM and calendar before launch, not after.
  4. Test with real staff asking difficult questions.
  5. Launch, then review conversations weekly for the first month.

We build AI website chat assistants to this standard, connected to your CRM and fully under your control.
