AI agent platforms are tools and frameworks that let you create, orchestrate, and automate autonomous AI agents – software entities powered by large language models (LLMs) that can perform multi-step tasks, use tools, and even collaborate with other agents. Unlike single-function AI tools, agent-based platforms enable building task-driven agents or teams of agents that carry out complex workflows end-to-end. This is especially powerful in content creation and digital marketing, where processes often involve research, content generation, editing, publishing, SEO analysis, lead outreach, and more. By chaining together AI reasoning with integration to web apps and data sources, these platforms can automate content and marketing workflows in a more adaptive way than traditional rule-based automation.
