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.
How to Use AI Agents on Free.ai
- Choose an agent — Select from General, Code, Writing, Research, or Math above. Each has specialized knowledge.
- Start a conversation — Type your request and the agent will respond with its specialized expertise.
- Iterate — Ask follow-up questions, request revisions, or redirect the agent. It maintains full conversation history.
- Switch agents — Change agents anytime. Each has a different system prompt optimized for its domain.

FAQ
AI agents are autonomous systems that can plan multi-step tasks, maintain context across a conversation, use specialized tools, and adapt their approach based on results. Unlike simple chatbots that respond to a single prompt in isolation, agents on Free.ai remember your entire conversation history, follow complex instructions, and can switch strategies when their first approach does not work.
Free.ai offers five specialized agents: General Assistant for broad Q&A and brainstorming, Code Assistant for writing and debugging code in 50+ languages, Writing Assistant for drafting and editing text, Research Assistant for analyzing topics and comparing perspectives, and Math Tutor for step-by-step problem solving and concept explanations.
Yes. Every agent has a free daily token limit. Anonymous users get a base allowance, signing up triples it, and paid plans offer unlimited usage. Self-hosted models like Qwen 2.5 7B are completely free within your daily limit.
Yes. You can change agents at any time using the dropdown selector at the top of the chat interface. Each agent maintains its own separate conversation history, so you can switch back and forth without losing context.
By default, agents use Qwen 2.5 7B, a fast and capable open-source model running on our GPU servers. You can also access more powerful models like Qwen2.5-72B, Qwen2.5-Coder-32B for code tasks, and 346+ external models via OpenRouter including GPT-4o, Claude, and Gemini.
The agent maintains full conversation history for the duration of your browser session. Every message you send and every response it generates is included as context for future messages, so it can reference earlier parts of the conversation. Clearing the chat resets this history.
The Code Agent supports 50+ programming languages including Python, JavaScript, TypeScript, Java, C++, Rust, Go, Ruby, PHP, Swift, Kotlin, SQL, HTML/CSS, Bash, and many more. It can generate new code, debug existing code, perform code reviews, and explain how code works.
Yes. Free.ai does not use your inputs or outputs to train AI models. All traffic is encrypted with HTTPS. We do not sell or share your conversation data with third parties. See our security page for full details.
Yes. You can replicate the agent experience via the Free.ai REST API by sending a system prompt that defines the agent role along with your conversation messages. The API uses an OpenAI-compatible format, making it easy to integrate into your own applications.
The General Agent is optimized for broad Q&A, brainstorming, and everyday tasks. The Research Agent is specifically tuned to provide multiple perspectives, organize information with headers and bullet points, distinguish facts from opinions, and structure findings in a research-friendly format.
No. You can start using agents immediately without an account. However, creating a free account gives you 3x the daily token limit and a 50,000-token signup bonus, which means significantly more agent conversations per day.
Currently, agents are text-based conversational tools. However, you can manually chain outputs by copying agent text into other tools like image generation, text-to-speech, or translation. For fully automated multi-tool pipelines, check out our Workflows page or use the API to chain calls programmatically.
