What is an AI agent?
An AI agent is a system powered by artificial intelligence that pursues an objective on its own. The difference with a classic assistant is not capability but autonomy: an assistant waits for your instruction at every turn, while an agent decides the next step itself. Give it a goal, and it plans the work, uses tools such as browsers, applications or code, observes the results and corrects course until completion. Autonomy comes in degrees, from supervised sessions where you keep an eye on the agent, to continuous agents that trigger on events and run in the background.
Agentic AI: from single tasks to autonomous workflows
Agentic AI describes this shift from answering questions to executing work. In practice, the tools in this category cover the whole spectrum. General-purpose agents handle research, analysis and multi-step tasks in a cloud workspace. Agent builders let you assemble your own automations without code, connecting your email, calendar and business applications. Developer frameworks orchestrate multi-agent teams, where specialized agents collaborate on structured workflows. And vertical agents focus on one job done deeply, such as writing software or handling customer conversations across channels. Together they turn AI automation from a buzzword into everyday operations.
How to choose your AI agent platform
Start from who will use it: a no-code builder suits business teams, while an open-source framework gives developers full control. Then weigh four criteria. Integrations first: an agent is only as useful as the tools and data it can reach, so check the connectors for your stack. Supervision next: decide how long a leash you want, from approving each action to fully autonomous runs, and pick a platform that offers that level of control. Security matters: agents act on your systems, so review permissions, audit trails and data handling, especially for company use. Budget last: most of these platforms are AI SaaS whose pricing models vary widely, from per-task credits to seat-based plans, so use the pricing filters above to compare.
