Quick Setup (< 1 hour)

You can use Sim to create AI agents that automate real work without needing to write much code. It provides a visual drag-and-drop workflow builder, a chat interface for describing what you want to build, and direct code access. You connect it to over 1,000 tools like Slack, HubSpot, Salesforce, and Notion, pick any major LLM (OpenAI, Anthropic, Google, etc.), store data in knowledge bases and tables, and monitor every agent run with full logs and cost tracking.
