Serverless cloud for building, hosting, and monetizing domain-specialized AI agents, with RAG, orchestration, and per-message billing handled for you.
Kopai is a serverless platform for turning subject-matter expertise into AI agents that can be sold. Creators write a prompt, upload supporting documents, and compare a few models side by side; Kopai handles retrieval-augmented generation, orchestration, tool calls, model keys, the vector database, and the servers, so no backend code is required. Finished agents can be listed on Kopai's marketplace, where they earn per message and every charge is written to a readable ledger — creators keep 70% of their markup — or exported to run inside the creator's own product while still billing through Kopai. Agents must pass an evaluation step before they can be listed. A single gateway fronts multiple models including GPT-4o, Kimi K2, Gemini 2.5, Qwen 3, and DeepSeek, letting creators switch without reintegrating, and responses resume from where they stopped if a connection drops. For companies, Kopai for Teams adds seats and roles, private agents visible only to the team, shared knowledge bases, and usage reporting. Agents can also be created conversationally: describe the job in chat and Kopai works out which organization it belongs to and drafts it.
