AI agent, chatbot, or no-code: what to choose.

Three different things, often confused. Here’s what they actually do, who owns the code, and when each one makes sense, with no marketing.

In summary
  • A chatbot talks; an AI agent acts on your business processes.
  • No-code is useful for linear flows, but it brings platform dependence.
  • For core, high-volume processes with real integrations, a custom solution with code you own is the better call.

Which to choose

The practical rule

Choose the chatbot

if you need to deflect simple, repetitive questions (FAQs, first-line support) and don’t need to act on your systems.

Choose no-code

if the automation is linear, between standard tools, and you accept the platform dependence.

Choose the custom agent

if the process is core, high-volume, requires real decisions and integrations, and you want to own the code.

FAQs

The questions we get asked most

What’s the difference between an AI agent and a chatbot?

A chatbot answers questions with predefined replies. An AI agent understands a request, decides what to do, and carries it out: it sorts email, opens cases in your back-office system, takes bookings. In short, the chatbot talks; the agent acts on your business processes.

If I already have a no-code automation, do I need an AI agent?

It depends on the process. No-code is great for simple, linear automations between standard tools. When the process requires understanding unstructured input, deciding case by case, or integrating deeply with your systems, a custom AI agent holds up where no-code rules break down.

Is it better to buy a platform or have the solution built?

A platform is faster to start with but ties you to its model and its costs over time. A custom solution costs more upfront, but the code is yours, with no lock-in, and it fits your process exactly. For a core, high-volume process, a custom solution is usually the better call.

Transparency note

This comparison is here to remove ambiguity: chatbots, no-code, and AI agents solve different problems. The right choice starts from the process, not from whatever technology is most in fashion.
