The Best AI Agents 2026

The best AI agents 2026 are Google Vertex AI agents, Botpress, the fonio.ai AI phone call assistant, and Devin AI. Claude Computer Use, OpenAI GPT, Microsoft Copilot Studio, AutoGen, Lime Connect, and Expertise AI are among the most popular AI agents used by companies and private users.

AI agents are software programs that are tailored to the personal needs of a company or a user and take over automated workflows. Virtual agents are more than simple chatbots, because chatbots only react to instructions, while AI agents act proactively. An intelligent agent makes decisions and carries out tasks independently, based on the information provided.

Implementing an AI powered agent supports companies and individuals with daily repetitive tasks and customer support, based on instructions. With AI agents in place, employees become more productive because they focus on tasks that truly require a human. On site teams concentrate on real value creating work, while AI agents handle routine time consuming activities.

Below you will find a comprehensive list of the best AI agents plus frameworks and tools for building and managing AI driven agents in 2026.
