What does Sim AI do?

Sim AI is an open-source workspace where teams build, deploy, and manage AI agents. It connects over 1,000 integrations — including Slack, HubSpot, Salesforce, and Notion — and supports every major large language model. You can create agents visually, conversationally, or with code, and Sim handles the orchestration. The platform is SOC2 compliant and used by more than 100,000 builders, from small teams to enterprises like Rivian and eXp Realty.

What makes Sim stand out is its flexibility. You can describe an automation in plain English, and Sim builds the workflow for you — connecting the right blocks, models, and data sources. The visual builder lets you wire together agent logic block by block, and you can monitor every run with live traces, logs, and real cost tracking. Sim also stores your data semantically in tables, files, and knowledge bases, giving agents memory to reason over. The platform supports parallel agent execution and offers a catalog of pre-built integrations so agents can act across your existing tool stack.

Sim is best suited for technical teams — developers, operations engineers, and automation specialists — who want to automate complex workflows without building everything from scratch. Real-world use cases include lead enrichment and sales notifications, triaging support tickets and drafting replies, and syncing data across CRM, messaging, and project management tools. If your team needs a customizable, self-hostable agent platform that works with the tools you already use, Sim is worth a look.
