Why agents instead of plain chat?
A chatbot answers one question at a time. An agent has a role, remembers what you talked about, and stays in character across the entire conversation. Ours run on the same 346+ models — no signup, no credit card, no \u201cfree trial\u201d ceiling.

- Pick from 346+ models — self-hosted (free) or premium (passthrough)
- RAG over your uploaded knowledge — agent cites sources back
- Auto voice-chat enabled — users can call your agent
- Creator monetization — get a cut of every token spent on your agent
- API endpoint included — POST /v1/agents/@you/chat/

See WorkflowsWhat Are AI Agents?
AI agents are autonomous systems that can perceive their environment, make decisions, and take actions to achieve goals. Unlike simple chatbots that respond to a single prompt, agents can plan multi-step tasks, use tools, maintain memory across interactions, and adapt their approach based on results. On Free.ai, you can use agents for research, coding, content creation, data analysis, and more — all powered by open-source models.
