AI app building, defined
Short, plain-language definitions of the terms behind building software with AI.
AI app builder
An AI app builder is a tool that turns a plain-language description into a working software application, generating the code, interface and often the backend for you.
Read →Vibe coding
Vibe coding is building software by describing what you want in natural language and letting an AI handle the implementation, rather than writing the code yourself.
Read →Multi-agent coding
Multi-agent coding splits a build across several specialised AI agents — for code, design, database, deployment, QA and debugging — that work in parallel and review each other, instead of one model doing everything.
Read →Full-stack app
A full-stack app includes both the front end (what users see) and the back end (database, authentication, business logic and APIs) — a complete, working product rather than just a screen.
Read →Backend
The backend is the part of an app users don't see — the database, authentication, business logic and APIs that store data and enforce rules.
Read →No-code vs low-code vs AI-code
No-code builds apps visually with no programming; low-code mixes visual tools with some code; AI-code (or 'AI app building') generates real code from natural-language prompts.
Read →MVP (minimum viable product)
An MVP is the simplest version of a product that delivers core value and lets you learn from real users — the goal is learning, not perfection.
Read →SaaS (software as a service)
SaaS is software delivered over the web on a subscription, rather than installed — think a web app users sign into and pay for monthly.
Read →Agentic AI
Agentic AI describes AI systems that don't just answer — they take actions toward a goal: planning steps, using tools, and checking their own work, often as multiple coordinating agents.
Read →AI coding assistant
An AI coding assistant helps you write software using AI — from autocompleting code in an editor to building and shipping whole applications from a description.
Read →Conversational AI app
A conversational AI app is software you build (or use) through natural-language chat — you describe what you want and the AI produces or operates the app.
Read →Low-code
Low-code is building software mostly through visual tools and configuration, with the option to drop into code for the parts that need it.
Read →AI website builder
An AI website builder generates a website from a prompt — layout, copy and design — instead of you dragging elements or writing HTML.
