Why Agent Builder
Build agents step by step using a visual interface. Add tools from aiXplain marketplace or upload your own, and let AI auto-generate prompts and descriptions.
Onboard your own Python code as a tool and sync it with your IDE. Easily connect custom APIs or internal logic to power your agents.
Understand your agent’s reasoning at every step. Trace tool calls, review responses, and monitor usage costs to optimize with confidence.
Each agent comes with an API. Use it in your apps, services, or workflows through Python or Swift SDKs, or with a simple REST API call, and deploy it wherever it’s needed.
