Glossary: AI words in plain English

Plain definitions of the words used in our cases, for small business owners. Each term links to real cases we have published. Updated Thu, Oct 22, 2026, from the cases these definitions draw on.

What do these AI words mean for a small business?

They describe who does a job and how much choice it has. An AI agent can take steps on its own. An AI receptionist is an agent that answers calls and books work. Automation is a fixed set of steps that runs on its own. Lead scoring ranks new leads so the best ones get a reply first. Each term below links to real cases we have published.

AI agent

Software that can do a job in steps, not just answer a question. It reads the information it needs. It picks the next step. It acts: it can send a message, book a meeting, or update a record. A person sets the goal and the rules. The agent does the steps.

In our cases: a small agency uses five agents that scan for prospects, draft outreach, classify replies, and book meetings; a construction owner's agent handles the office work behind jobs, such as bidding and billing.

AI receptionist

An AI agent set up to answer the phone or a message line for a business. It answers common questions from the business's own information. It checks the diary or calendar. It books or moves appointments. It takes a message when it cannot help. It can work after hours, so a caller does not hit voicemail.

In our cases: a salon agent answers questions from the services and price list, checks the diary, and books appointments; an HVAC firm's agent answers callers around the clock, asks what they need, checks for real open slots, and books their pick.

Automation

A fixed set of steps that runs on its own when a trigger fires. A person builds the steps once. After that, the same steps run each time, in the same order, with no choices in between. If a step fails or the data does not match, a good setup sends the item to a person to check.

In our cases: when a purchase order is approved in one tool, a set of steps creates the matching order and bill in the accounting tool; supplier invoices are read, checked, and filed, and any invoice with a problem goes to a review queue for a person.

Lead scoring

A way to rank new leads. Each lead gets a score or a rank based on rules the business sets, such as the job type, the place, or how soon they want work. High leads get a fast reply. Low leads get a slow reply or a polite no. In many of our cases, the same job is called qualifying: an agent asks a few set questions, then sorts the lead.

In our cases: a roofing contractor's agent asks four set questions by text and books a site visit for real leads; a sales builder describes scoring agents that sit next to a research agent in the same pipeline; a Make setup with AI modules qualifies new leads as they arrive.
