Build a team of agents around your business with Symphony by Wix →
Most explanations of what an AI agent builder is start by describing agents, which is a bit like explaining a bakery by describing bread.
The builder is the tool and the agent is what comes out of it. Getting that the right way round matters because the thing you're actually choosing between is AI agent builders and they differ far more than the agents they produce.
Symphony by Wix builds a team of AI agents around your business, and you create custom ones by chatting rather than configuring. You set the name, the personality and the actions each agent is allowed to take.
TL;DR: what is an ai agent builder
An AI agent builder is a platform for creating, testing, deploying and improving AI agents, the kind that reason through a request, pick the right tools and carry out several steps toward a goal.
You define the outcome and the guardrails and your AI agent builder handles the orchestration, memory, integrations and logging underneath. They come in three broad types and the gap between them is skill, not capability.

What is an AI agent builder?
An AI agent builder, like Symphony by Wix, is a no-code or low-code platform that lets you build, test, deploy and improve AI agents. The agents it produces run on large language models, which is what lets them reason about a request, decide which tools to use and take several steps toward a goal rather than answering and stopping.
An AI agent builder gives you somewhere to define agents, connect data and tools, set the rules they operate under and watch what they do once they're running. Without one you'd be wiring an agent together yourself and maintaining it forever.
Before you start: the phrase gets used loosely and sometimes means an app builder that happens to include AI features. Those build software, an AI agent builder builds something that acts on your behalf. It's worth checking which one a product actually is before you get far into an evaluation.
How an AI agent builder works
The division of labor is the useful part.
You define the goal and the boundaries.
The agent gathers context, works out the next step and takes action inside the guardrails you set.
Nothing about that requires you to specify how the work gets done, only what counts as done and what's off limits.
Underneath, most AI agent builders combine the same five things.
Reasoning is how the agent decides.
Orchestration is how work moves between agents or steps.
Memory is what carries over.
Integrations are what it can reach.
Governance is the logging, policies and evaluation that let you see what happened and correct it.

How it actually works: on Symphony by Wix you don't assemble any of those pieces yourself. An orchestrator called Maestro gets to know your business, surfaces actions worth taking and hands work to the right agents. You describe what you want rather than building the infrastructure that makes it happen.
The three types of AI agent builders
No-code builders
These use guided steps, templates or plain conversation and they're built for people with no programming background. You describe the job and the AI agent builder, like Symphony by Wix, produces something that can do it.

Low-code builders
Low-code tools expose the underlying logic so a technical person can adjust it without starting from scratch. This is the middle ground and it suits teams with someone who can read a workflow and edit a step even if they wouldn't call themselves a developer.
Pro-code frameworks
At the far end sit frameworks that hand developers full control over memory, tool access and orchestration. Nothing is hidden and nothing is decided for you, which is exactly the appeal and exactly the cost. These assume engineering time both to build and to keep running.
Keep in mind: Symphony by Wix is built for independent business owners and small teams. It's designed for the pace and structure of a small business rather than enterprise engineering workflows, which is why it sits firmly in the first category rather than trying to span all three.
Agent builder, agent, assistant: what's the difference
These three get used interchangeably and they aren't the same thing.
An AI agent is the thing that does the work. It reasons, uses tools and completes multi-step tasks with some independence.
An assistant responds when you ask. It's reactive by design, which makes it excellent for questions and drafting and unsuited to anything that has to happen while you're not watching. The difference between an agent and an assistant is mostly about who starts the interaction.
The builder is neither, it's the environment where agents get made, configured, connected and supervised. You can have an agent without ever seeing a builder, in the same way you can eat bread without visiting a bakery but if you want agents shaped around your own business you're going to end up in one.
Something most people don't expect: custom agents built this way don't run off to one side. On Symphony by Wix they operate inside the same orchestrated system as the built-in agents, sharing context and coordinating with them, so a new agent inherits what the others already know about your business.
What to look for in an AI agent builder
Start with the control model, because it's the thing you'll feel every day. Can the agent act on its own? What needs your sign-off? A builder that asks before doing anything consequential behaves very differently from one that runs unattended and neither is universally right.
Then look at reach and reversibility, so this means what can it connect to, how fast can you switch that access off and can you see a record of what it did. A builder that makes agent activity visible is worth more than one with a longer feature list and no window into the work.
Last, weigh the cost of changing your mind. Some builders make the first agent easy and the tenth painful while others front-load the effort and stay flat. Which pattern suits you depends on how much you expect to iterate and most teams iterate more than they plan to.

Building agents without a developer
This is the case most small businesses are in,and it's where no-code AI agent builders, like Symphony by Wix, stop being a compromise and start being the point. The work becomes describing your business accurately rather than translating it into configuration.
On Symphony by Wix you create and train an agent by setting its name, giving it a personality and approving the goals and actions it's allowed to pursue. Those rules are your rules, written the way you'd explain them to someone new. Custom agents can be connected to the tools you already use and deployed across any part of your operation.
A setup decision worth making early: the more tools you connect, like your calendar, CRM, payment platform and back office, the more your agents can do on your behalf. Connecting your existing stack early significantly expands what the agents can handle without additional input from you.

AI agent builder FAQ
Is an AI agent builder the same as an AI agent?
Not at all, an agent is the thing that does the work, reasoning through requests and completing multi-step tasks. The builder is the platform where agents are created, configured, connected to tools and supervised. You choose an AI agent builder and you get agents out of it.
Do you need coding skills to use an AI agent builder?
It depends entirely on the type. No-code AI agent builders, like Symphony by Wix, are designed for people with no programming background and some let you create an agent through conversation alone. Pro-code frameworks assume a developer. Low-code tools sit between the two and suit someone technical who isn't an engineer.
What can you actually build with one?
Agents that handle a defined area of work, like outreach, scheduling, marketing, research or finance admin. The useful pattern is one agent owning one area rather than a single agent trying to do everything, which is why many platforms coordinate several agents at once.
What's the difference between an AI agent builder and an AI app builder?
An app builder, like Base44, produces software that people use. An agent builder produces something that acts on your behalf inside your business. The names are close enough to cause real confusion, so it's worth confirming which category a product falls into early on.
How much control do you keep over what an agent does?
That varies by builder and it's the most important thing to check. Some agents act autonomously within permissions you set. Others check with you before anything consequential happens. Symphony by Wix uses the second model, where actions come to you for approval before they run.
Can agents built this way work together?
On platforms that coordinate multiple agents, yes. Symphony by Wix runs custom agents inside the same orchestrated system as its built-in ones, so they share context and coordinate rather than operating in isolation.
