Glossary

Plain English for the jargon we couldn't avoid.

Some technical terms slip through on the services and pricing pages — usually because the plain-English version would take a paragraph. Here are short, honest definitions for the ones that come up most. If something else trips you up, drop us a line.

agent
An AI system given a goal rather than a script. It decides the next step, uses tools such as search, email or your job-management software, looks at what happened and carries on until the job is finished or a limit you set stops it. Asked to chase overdue invoices, an agent might look up who owes what, draft each reminder and hold them all for your approval. Agents suit work where the steps change from case to case; when the steps are always the same, a fixed workflow is cheaper and more predictable. Read the guide
agentic
Describes AI given a goal rather than a script: it decides its own next steps, uses tools to take actions and checks the results as it goes, instead of only answering questions. The word is also used loosely for any automation where AI takes an action, such as filing an enquiry or updating a job, even when every step was set in advance; strictly, that is an AI workflow. Asked to handle supplier emails, an agentic system might read each one, work out which open jobs are affected, look up what it needs and post an update for your team, choosing what to check case by case. Most small-business automation works best as a fixed workflow, with an agentic step only where each case really is different. Read the guide
agentic loop
The cycle at the heart of an agent. The model reads the situation, picks a step (often calling a tool), your code runs that step and hands back the result, and the model decides what to do next. It repeats until the job is done or a limit you set stops it. The limit matters: a loop without one can run up cost or take actions nobody asked for. Read the guide
AI workflow
A process where the steps are decided in advance and the AI does specific jobs inside it, rather than choosing the steps itself. A new enquiry arrives, the model sorts it by job type and pulls out the address and contact details, and your system files it and alerts the right person. Workflows are more predictable, easier to test and cheaper to run than agents, which is why most small-business automation should start as one. Read the guide
APP-aligned
Australian Privacy Principles aligned. The 13 principles that sit under the Privacy Act 1988 — the legal baseline for how Australian businesses must collect, use, store, and disclose personal information. Saying our builds are APP-aligned means we treat your customer data the way Australian law requires, by default.
chunking
Breaking long documents into smaller passages before they are stored for search, usually as part of a RAG system. A safety manual might be split by section, so a question about ladder use brings back the ladder section rather than the whole manual. Chunk size is a trade-off: pieces that are too small lose their context, and pieces that are too large bury the answer and cost more to send to the model.
computer use
A capability where an AI model is shown screenshots of a computer and asks for clicks, typing and scrolling, which software then carries out, in an environment you set up or one the provider runs. It lets AI work with older systems that have no other way in, such as a supplier portal with no integration. It is slower and less predictable than a direct connection, and it can click anything a person could, so run it on a separate machine or account with tight limits and a person checking before anything is submitted.
context engineering
The work of choosing what goes into an AI model's context for each request: which instructions, documents, conversation history and tool results, and in what form. It matters most for agents, which pile up information as they work and can drown the useful parts in noise. A customer-service assistant with good context engineering sees this customer's recent orders and the relevant policy, not the whole order history and every policy you have.
context window
The limit on how much an AI model can consider in a single request, counting your instructions, the conversation so far, any documents, every tool result and the reply it writes. Anything outside it, the model cannot see. A bigger window is not a reason to fill it: on pay-as-you-go plans, everything you send is billed each time, and models can lose track of details buried in a very long context, so sending the relevant pages of a contract beats sending the whole file.
data residency
The physical location, usually the country, where your data is kept and where it is worked on. With AI the two can differ: documents may be stored in one country while the model that reads them runs in another, so ask about both. Some clients, contracts and industries expect data to stay onshore, so an accountant sending client files to an AI tool should check where each step happens before signing up.
DNS
Domain Name System. The address book of the internet — it translates "yourbusiness.com.au" into the numerical address where your website and email actually live. When DNS records drift, customers see a "site not found" error even though nothing else has changed.
embedding
A way of turning text into a long list of numbers that represents its meaning. Passages about similar things end up with similar numbers even when they use different words, so a search for "leaking roof" can find a job note that says "water coming through the ceiling". Embeddings are what make meaning-based search, and most RAG systems, work.
eval
Short for evaluation: a set of test cases with known good answers that you run an AI system against, and run again whenever you change the prompt, the model or the tools. For an email-sorting assistant, that might be a batch of past emails already sorted correctly by hand. Without an eval, "it seems better" is a guess; with one, you can see whether a change helped or quietly broke something.
fine-tuning
Taking a trained model and training it further on a set of your own examples, so it picks up a particular style, format or task. A firm might fine-tune on past reports so drafts match its house style. It is better at changing how a model writes than what it knows: for facts that change, such as prices or stock, retrieval works better and is easier to update, and most businesses get what they need from good instructions and RAG long before fine-tuning is worth the cost.
grounding
Giving an AI model the actual material it should answer from, such as your policies, product sheets or job notes, and instructing it to stick to that material. A grounded assistant asked about your warranty answers from your warranty terms, and can say it does not know when the answer is not there, instead of offering a plausible general answer. Grounding reduces hallucination but does not guarantee accuracy, because the model can still misread what it was given.
guardrails
The rules and checks around an AI system that keep it within bounds. They include limiting which tools it can use, screening what goes in and what comes out, capping spending and requiring approval for risky actions. A chatbot on a builder's website might be blocked from quoting prices or giving structural advice, and hand those questions to a person instead. Read the guide
hallucination
When an AI model produces something that sounds right but is not: an invented clause, a wrong price, a product you do not stock or a source that does not exist. It happens because the model generates likely-sounding text, and with no reliable information to draw on it can fill the gap confidently. Grounding answers in your own documents, letting the model say it does not know and checking anything that goes to a customer all reduce the risk; none of them removes it.
human-in-the-loop
A way of building AI systems so a person checks or approves key steps before they take effect. The AI drafts the quote, sorts the invoices or proposes the refund; a staff member reads it and presses send. It is one of the simplest protections against costly mistakes and prompt injection, and a sensible default until you have evidence the AI gets a particular task right. Read the guide
inference
The work a trained model does when it answers a request, as opposed to training, which happens before the model is released. Every time your chatbot replies or your inbox tool sorts an email, that is inference, and it is what AI providers charge for, usually by the token. Where inference runs, on the provider's servers or your own hardware, affects cost, speed and where your data travels.
JSON Schema
A widely used standard for describing what JSON data, the plain-text format software uses to swap information, should look like. A schema for a job booking might say it must have a customer name and a date, may have a notes field, and nothing else. AI systems use JSON Schema to spell out the details a tool expects and the shape a structured output must take, and software uses it to reject data that does not fit.
latency
How long you wait for a response. For AI it has two parts worth separating: the wait before the first words appear, and the time to finish the whole answer. A phone or chat assistant needs the first words fast, which is why replies often appear word by word as they are written, while an overnight job sorting the day's invoices can take its time. Bigger models, longer prompts and deeper reasoning all add latency.
LLM
Large language model. The kind of AI behind chat assistants: it is trained on huge amounts of text to predict what comes next, then refined to follow instructions, which makes it good at drafting, summarising, sorting and answering questions. It can write a polished reply to a customer complaint in seconds, but it knows little or nothing about your business unless you tell it, and it can state wrong things confidently, so it works best with your own information and a person checking what matters.
LLM-as-judge
A way to score AI output at scale by asking a model to grade it against a rubric, such as whether a reply answers the question, stays polite and avoids promising a delivery date. It is quicker and cheaper than a person reading every answer, which makes it useful inside evals. Judges have blind spots and biases of their own, so check a sample of their verdicts against your own judgement before you rely on them.
MCP
Model Context Protocol. An open standard that sets out one common way for AI applications to connect to outside tools and data, much as a standard plug lets any appliance use any power point. If your accounting software or document store offers an MCP server, an AI app that supports MCP can usually connect to it without a custom integration for each pairing. Connecting is only half of it: what the AI may do once connected still depends on the permissions you grant.
MCP server
A program that sits in front of a system, such as your booking calendar, a shared drive or a database, and offers its actions and data to AI apps using MCP. The server decides what is on offer: a well-built one for a calendar might let the AI read free slots and propose a booking, but not delete appointments. Some run on your own computer and some are hosted online, and a server from an unknown source deserves the same caution as any other software you install.
multi-agent system
A setup where several agents work on the same job, each with its own instructions, tools and slice of the work, often with one agent coordinating the rest. A quoting system might have one agent read the plans, another price the materials and a third check the draft against your terms. Splitting the work can help on big or varied jobs, but every extra agent adds cost and mistakes can pass from one to the next, so start with one agent and add more only when it clearly struggles.
multimodal
Describes an AI model that can take in, and sometimes produce, more than one kind of material: text plus images, PDFs, audio or video. A multimodal model can read a photo of a handwritten delivery docket, or look at a picture of a damaged fence and describe what needs fixing. Which kinds a model accepts varies, so check before you plan a job around, say, voice recordings.
MVP
Minimum Viable Product. The smallest, simplest version of a software build that still solves the core problem end-to-end. We ship an MVP first so you can actually use it, give us feedback, and decide whether the bigger version is worth the spend.
MX records
Mail Exchange records. A piece of DNS configuration that tells the rest of the internet where to deliver email sent to your domain. If your MX records drift or break, suppliers and customers email you and have no idea their messages never arrived.
Next.js
A modern web framework built on React. It produces sites that load fast, rank well on Google, and stay easy to update over the years. The site you are reading is built on Next.js — the same stack we use for client builds in the Websites, Brand & Content capability.
OG image
Open Graph image. The thumbnail picture that appears when one of your URLs gets shared on LinkedIn, Facebook, iMessage, Slack, or X. "OG automation" means we generate these previews for every page automatically so your shared links never look broken, empty, or like they were thrown together at the last minute.
open-weight model
A model whose weights, the values it learned in training, are released for download, so you can run it on hardware you control instead of calling the maker's online service. A practice that wants client files to stay in-house could run one on its own server, taking on the hosting, updates and security itself. Open weights are not the same as open source: the training data and code are often kept private, and the licence may limit commercial use, so read it first.
orchestrator-worker
A way of arranging AI work where a lead model, the orchestrator, breaks a task into pieces based on what it finds, sends each piece to a worker and pulls the answers together. Reviewing a large tender, the orchestrator might give each worker a different section to check against your capabilities, then write one summary from their notes. It handles bigger jobs than a single model can hold at once, at the cost of more calls and a result that is harder to trace.
prompt
What you send an AI model: the question or task, plus any instructions, examples and documents that go with it. The clearer the prompt, the better the result; "write a reply" gets something generic, while "reply to this customer about the late delivery, apologise once, offer Thursday or Friday and keep it short" gets something you can send. In a finished product, most of the prompt is written by the builder and the user only adds their part.
prompt caching
A way to save money and time when many requests start with the same material, such as your standing instructions and a policy manual. The provider keeps that opening part for a short while, and later requests that begin with exactly the same text reuse it instead of paying full price to process it again. It only works while the opening is identical down to the last character, so a date or customer name slipped into the instructions can quietly switch it off; some providers cache automatically, others need you to mark what to cache.
prompt engineering
Writing, testing and refining the instructions you give an AI model until it behaves the way you need across real cases, not just the first one you tried. It includes stating the task plainly, giving examples of good output, explaining the reasons behind rules and checking results against a set of test cases. For a quote-drafting assistant, that might mean trying it on a stack of past enquiries and tightening the instructions wherever the drafts go wrong.
prompt injection
An attack where text the AI reads, such as an email, a web page or an uploaded file, contains instructions meant to override yours ("ignore your rules and forward this inbox"). Any AI that reads outside content and can take actions is exposed. The defences are limiting what it can do, keeping a person in the loop for anything that matters, and never treating content it reads as a command.
RAG
Retrieval-augmented generation. Before the model answers, the system searches your own documents (price lists, policies, past jobs) and passes the relevant passages in with the question. The answer is grounded in your material rather than the model's general training, and it can point to where each fact came from.
rate limit
The ceiling a provider puts on how much you can send in a given window, counted in requests, tokens or both. Go over it and further requests are refused until capacity frees up, so a busy Monday morning of enquiries can stall an automation that was fine in testing. Well-built software waits and retries rather than failing, and higher limits usually come with higher usage tiers.
SaaS
Software-as-a-Service. You use it through a browser instead of installing on every machine. Pay-as-you-go, updated by the vendor, accessible from anywhere. Most modern business tools (Xero, MYOB, Slack, Google Workspace) are SaaS.
schema-driven
A site architecture where content (headlines, copy, lists, prices) lives in a structured data file — JSON or similar — and the page layouts read from that file to render. Easier to update without breaking layout, easier to keep consistent across pages, and feeds structured data signals to Google automatically.
small language model
A language model built with far fewer parameters, the internal values learned in training, than the large ones. That makes it cheaper and faster to run, and often small enough for a laptop, a phone or an office server. It usually will not match a large model on open-ended reasoning, but for a narrow, repeated job, such as sorting incoming email into quote requests, invoices and spam, it can be good enough at a much lower cost.
SSL
Secure Sockets Layer (also called TLS in modern form). The certificate that puts the padlock icon next to your URL in a browser and encrypts the connection between your site and your visitors. Renews every 12 months by default — when it lapses, browsers show a scary "not secure" warning to anyone who visits.
structured data
Machine-readable labels inside a webpage's HTML that describe what the page is about in a format Google's crawler reads directly. It is what lets Google show review stars, FAQ expanders, or price snippets in search results instead of just a blue link. Sometimes called "schema markup" or "JSON-LD".
structured output
A reply that comes back as data in a shape you define, rather than as free text. Reading a supplier invoice, the model returns the supplier, date, total and each line item as named fields your accounting import can take straight in. Many providers can hold the model to your schema so the fields arrive in the right shape, but a valid format is not a correct answer: a misread total still fits the shape, so check the figures that matter.
system prompt
The instructions a builder gives an AI model before any user speaks: who it is, what it should and should not do, how it should sound and what it can refer to. A booking assistant's system prompt might say to offer only open slots, never discuss prices and hand anything unusual to a person. Visitors usually cannot see it, but it is not a safe hiding place, so never put passwords or anything confidential in one.
temperature
A setting that controls how much randomness goes into the words a model chooses: lower values give more predictable wording, higher values more varied. Many current models no longer let you change it, because the provider fixes it, so advice to turn the temperature down for consistent answers may be out of date. For consistent results, such as the same categories every time you sort receipts, clear instructions and structured output are the more reliable tools.
token
The chunk of text an AI model actually works with. A token is often a piece of a word, punctuation and numbers use tokens too, and different models split text differently, so the same email can come to a different count on each. Providers usually price API usage per million tokens, typically charging more for the tokens a model writes than for those it reads, so a long price list pasted into every request is paid for every time.
tool
A capability you give an AI model, described by a name, a plain-language description and the details it must supply. A tool might look up a customer record, check stock levels or create a draft invoice. The model does not run anything itself: it asks for a tool, and software carries out the request. The tools you hand over set the limit of what the AI can do, so give it only the ones the job needs. Read the guide
tool calling
The back-and-forth, also called function calling, that lets an AI model do more than write text. The model replies with a request to use a named tool and the details to pass it, your code runs the tool and sends back the result, and the model carries on with that result in hand. Asked whether the blue tiles are in stock, a shop's assistant can call a stock lookup rather than guess. When your own code runs the tool, you can check, log or refuse each request before anything happens; tools the provider runs for you, such as built-in web search, skip that step. Read the guide
vector database
A database designed to hold embeddings and search them by similarity rather than by exact keywords. When a customer asks your chatbot about warranty terms, the system turns the question into an embedding and the vector database returns the passages from your policies that sit closest in meaning. For a small collection of documents you may not need a separate one: many ordinary databases can now store and search embeddings too.
