AI Agents

Autonomous AI agents that plan and take actions on your behalf across tools and tasks. To build your own, see Agent Builders & Frameworks; for conversational bots you simply chat with, see AI Chatbots.

Want to build your own agent instead of using a ready-made one? Browse Agent Builders & Frameworks →

The tools here are autonomous or semi-autonomous agents that carry out multi-step work: browsing, calling tools and APIs, and completing tasks with limited supervision. This is different from AI Chatbots, which you converse with directly, and from Agent Builders & Frameworks, which are the platforms for constructing agents. Choose this category when you want software that does things, not just answers questions.

Top picks

01
Lindy logoLindy

Relevance AI logoRelevance AI

Relevance AI is an enterprise AI workforce platform for building and managing business agents at scale

Best for building custom AI agents and multi-step automations without heavy coding, useful for ops and go-to-market workflows. The caveat is real reliability still requires careful prompt and tool design, so it is not truly no-effort.

Agentforce logoAgentforce

Agentforce is Salesforce's enterprise AI agent platform that enables companies to build, deploy, and manage autonomous AI agents at scale

Hard to beat if your data already lives in Salesforce, since agents act directly on CRM records and flows. But the value is tied to that ecosystem and its data hygiene, and consumption-based pricing means costs climb with usage.
