Agent.so is a web platform that puts AI agents, AI apps and several large language models in a single account. The company calls it the original AI agents platform and uses the tagline "Your Portal to AI". Users chat with prebuilt agents or create their own for business tasks.
The library includes more than 250 agents covering coding, copywriting, advertising, finance, hiring, legal writing, tutoring and travel planning. The platform is aimed at freelancers, consultants, startups and mid-sized organizations that want to speed up routine work.
Users sign up for a free account and pick an agent from the library to start chatting. Each agent is tuned for a role, such as an internet marketer, a software developer or a financial advisor. Conversations are described as private, and the site says it does not share data.
To build a custom agent, users follow a short setup flow with no coding, then customize the agent and train it on files, links and sitemaps. The Plus plan lets users run agents on models from OpenAI, Anthropic, Google and other providers.
