Glossary
Terms that come up when people talk about AI, automation and websites.
- AI agent
A program that uses a language model to understand a request and take actions, such as replying, querying a system or booking, instead of only generating text.
- API
A standard way for one system to talk to another. One side makes requests, the other answers with data.
- Automation
Automatic execution of a task someone used to repeat by hand. The computer follows fixed rules or uses AI.
- Backup
A copy of data used to recover it after loss or failure. Test that the copy can restore what was saved.
- Chatbot
A program that talks by message. It can follow a fixed script or use AI to understand what the person wrote.
- Core Web Vitals
Google's three page-experience metrics: LCP (loading, target 2.5 s or less), INP (response to taps, 200 ms or less) and CLS (layout stability, 0.1 or less).
- CRM
A system that stores customers, contacts and the history of each deal.
- ERP
A management system that brings finance, inventory, tax and purchasing into one place.
- Idempotency
A property that lets an operation be repeated without duplicating its effect. For payments, it prevents a retry from creating another charge for the same order.
- Integration
A link between two systems so they share data on their own, usually through an API or a webhook.
- Landing page
A page with a single goal, built for an ad, a launch or to capture leads.
- LGPD
Brazil's General Data Protection Law (Law No. 13,709/2018). It sets how companies may collect, use and store personal data in Brazil.
- LLM (language model)
An AI model trained on large amounts of text to read and write natural language. Claude, Gemini and GPT are examples.
- MVP
The smallest version of a product that already solves the main problem. It lets you test with real users before building the rest.
- No-code
Tools that let you build automations and apps with little or no code, such as Zapier and n8n.
- Offline
Use without an internet connection. A system must define which tasks remain available and how data will be sent when the connection returns.
- Permissions
Rules defining which data each user may read and which actions they may perform. The server must check these rules rather than only hiding buttons.
- Prompt
The text instruction you give an AI model. A good prompt says what to do, with which information and in what format to answer.
- PWA
A web application that can offer installation on a device and features such as offline use. Installation and capabilities depend on the browser, operating system and what was built.
- RAG
A technique where the AI looks up the company's documents before answering. The reply combines your information with what the model learned in training.
- Rate limit
A restriction on how frequently an application may call an API. HTTP status 429 indicates too many requests; the server may say how long to wait before retrying.
- Responsive
A layout that adapts to the screen size, from a phone to a large monitor.
- SaaS
Software sold as a service: people use it over the internet and usually pay a subscription.
- SEO
The practices that help a page get found and rank well on search engines like Google.
- Structured data
Code people do not see on the page that tells search engines what the content is: a business, a service, an article, an FAQ.
- Tenant isolation
Controls that prevent one business from accessing another business’s data or resources in shared software such as SaaS.
- Token
A chunk of text an AI model processes. It is the unit used to measure usage and calculate cost.
- Webhook
An automatic notice one system sends to another when something happens, like an approved payment or a new order.
- WhatsApp Business API
