Nefi.ai is a cloud-based platform for designing, training, and orchestrating AI-powered agents without writing code. It offers a visual canvas to assemble blocks like LLM modules, vector database retrieval, external API calls, conditional logic, and memory stores. Agents can be trained on custom documents or linked to enterprise data. Once built, they deploy as chatbots, email assistants, or scheduled tasks. Advanced features include monitoring dashboards, version control, role-based access, and integrations with Slack, Teams, and Zapier.
