Open-source workspace to build, deploy and govern AI agents
Create agents by describing them in Chat, arranging blocks on a visual canvas, or writing code and CLI commands, and deploy the result without rebuilding it.
Sync and auto-update documents from Notion, Google Drive, Confluence, Slack, GitHub and SharePoint so agents ground answers in current company knowledge.
Agents read and write structured data in Sim Tables and keep files and artifacts organized in one shared store across runs.
Trace every agent run block by block with success rate, latency, execution cost and failure details for debugging and reporting.
No-code AI agents grounded in your company's knowledge
Configure AI agents through a visual interface, connect company data for context-aware actions, and swap between models without rewriting your setup.
Ground agents in internal docs, wikis and tools so they can research and act on company knowledge alongside the public web.
Build multi-step automations in a node-based editor and schedule agents to run recurring work even when you are offline, delivering results to your inbox.
A browser extension brings the same agent experience to thousands of apps and websites, avoiding constant context switching.
