    What a website AI assistant can do well

    Modern AI assistants can answer questions in natural language using your own content — services, pricing, policies, hours, and FAQs — and hand visitors off to a person or a booking form when needed. They work best for high-volume, repeatable questions, not complex judgment calls.

    What drives the cost

    Costs vary widely, so it helps to know the components:

    • Setup: preparing and structuring your content, designing conversations, and building the interface
    • Integrations: connecting to booking, CRM, order status, or support systems
    • Usage: AI providers typically charge based on volume of conversations
    • Guardrails and testing: making sure the assistant stays accurate and on-topic
    • Ongoing tuning: reviewing conversations and improving answers over time

    Risks to plan for

    An assistant speaks on behalf of your business, so plan for these risks up front:

    • Incorrect answers — limit the assistant to approved content and route uncertain questions to people
    • Privacy — avoid collecting sensitive information in chat unless the system is designed for it
    • Manipulation — users may try to make the assistant say things it shouldn't; test for this
    • Brand voice — set tone and boundaries, and review conversations regularly
    Be careful how you describe AI to customers. In 2024 the U.S. Federal Trade Commission brought a sweep of enforcement actions ("Operation AI Comply") against companies over deceptive AI claims. Describe what your assistant does accurately.

    How to measure ROI

    Track the assistant against goals you set before launch:

    • Share of questions answered without staff involvement
    • Leads or bookings started from chat
    • Response time compared with email or phone
    • Escalations and customer satisfaction
    • Staff hours saved per week

    A sensible rollout

    Start with your top 20–30 questions, launch on one or two pages, review every conversation for the first few weeks, then expand. AI adoption is now widespread — McKinsey reports 88% of organizations use AI in at least one function — but careful rollouts are what turn experiments into results.
