Stewrd is infrastructure for AI agents — orchestration, tool execution, file storage, and sandboxing. You bring your own LLM API key (OpenAI or OpenRouter) so you control model choice and costs. Your key handles the thinking, Stewrd handles the doing. Your key is encrypted at rest and never logged.
