We're excited to introduce Sim v0.5, the next evolution of our agent workflow platform—built for teams who need context-aware AI assistance, seamless tool deployment, and full execution observability in production.

Get things done faster

You're focused on the most critical tasks, let agents handle the rest.

Copilot is a context-aware assistant embedded directly into the Sim editor. It has first-class access to your workflows, blocks, execution logs, and documentation—helping you build, debug, and optimize without leaving the canvas. Ask it to explain a workflow, propose changes, or execute actions. All writes are gated behind explicit approval, so you stay in control.

Deploy any workflow as an MCP tool and expose it to any MCP-compatible agent—Claude Desktop, Cursor, or your own applications. Define custom tool names, descriptions, and parameter schemas. Your workflows become reusable building blocks that other agents can invoke, turning Sim into the backend for your agentic systems.

Full observability for every execution. Trace spans show you exactly what happened at each step—durations, token usage, cost breakdowns by model, and error details when things go wrong. Filter by time range, trigger type, or workflow. Live mode auto-refreshes every 5 seconds. Restore any previous workflow state with execution snapshots.

Invite teammates to your workspace and build workflows together in realtime—like Figma for AI agents. See cursors move, blocks added, and configurations updated as they happen. The operation queue ensures reliability even under poor network conditions. Undo/redo works per-user, so your changes stay separate from your collaborators'.
