Sim is an open-source visual workflow builder for building and deploying AI agent workflows. Design intelligent automation systems using a no-code interface—connect AI models, databases, APIs, and business tools through an intuitive drag-and-drop canvas. Whether you're building chatbots, automating business processes, or orchestrating complex data pipelines, Sim provides the tools to bring your AI workflows to life.
What You Can Build
AI Assistants & Chatbots
Build intelligent conversational agents that integrate with your tools and data. Enable capabilities like web search, calendar management, email automation, and seamless interaction with business systems.
Business Process Automation
Eliminate manual tasks across your organization. Automate data entry, generate reports, respond to customer inquiries, and streamline content creation workflows.
Data Processing & Analysis
Transform raw data into actionable insights. Extract information from documents, perform dataset analysis, generate automated reports, and synchronize data across platforms.
API Integration Workflows
Orchestrate complex multi-service interactions. Create unified API endpoints, implement sophisticated business logic, and build event-driven automation systems.
How It Works
Visual Workflow Editor
Design workflows using an intuitive drag-and-drop canvas. Connect AI models, databases, APIs, and third-party services through a visual, no-code interface that makes complex automation logic easy to understand and maintain.
Modular Block System
Build with specialized components: processing blocks (AI agents, API calls, custom functions), logic blocks (conditional branching, loops, routers), and output blocks (responses, evaluators). Each block handles a specific task in your workflow.
Flexible Execution Triggers
Launch workflows through multiple channels including chat interfaces, REST APIs, webhooks, scheduled cron jobs, or external events from platforms like Slack and GitHub.
Real-time Collaboration
Enable your team to build together. Multiple users can edit workflows simultaneously with live updates and granular permission controls.
Integrations
Sim provides native integrations with 80+ services across multiple categories:
- AI Models: OpenAI, Anthropic, Google Gemini, Groq, Cerebras, local models via Ollama or VLLM
- Communication: Gmail, Slack, Microsoft Teams, Telegram, WhatsApp
- Productivity: Notion, Google Workspace, Airtable, Monday.com
- Development: GitHub, Jira, Linear, automated browser testing
- Search & Data: Google Search, Perplexity, Firecrawl, Exa AI
- Databases: PostgreSQL, MySQL, Supabase, Pinecone, Qdrant
For custom integrations, leverage our MCP (Model Context Protocol) support to connect any external service or tool.
AI-Powered Copilot
Ask Questions & Get Guidance
Copilot answers questions about Sim, explains your workflows, and provides suggestions for improvements. Use the @ symbol to reference workflows, blocks, documentation, knowledge, and logs for contextual assistance.
Build & Edit Workflows
Switch to Agent mode to let Copilot propose and apply changes directly to your canvas. Add blocks, configure settings, wire variables, and restructure workflows with natural language commands.
Adaptive Reasoning Levels
Choose from Fast, Auto, Advanced, or Behemoth modes depending on task complexity. Start with Fast for simple questions, scale up to Behemoth for complex architectural changes and deep debugging.
