Sim is the open-source AI workspace where teams build, deploy, and manage AI agents. Create agents visually with the workflow builder, conversationally through Mothership, or programmatically with the API. Connect AI models, databases, APIs, and 1,000+ business tools to build agents that automate real work — from chatbots and compliance agents to data pipelines and ITSM automation.

## 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 Builder**  
Design agent logic using an intuitive drag-and-drop canvas. Connect AI models, databases, APIs, and third-party services through a visual interface that makes complex automation 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 1,000+ 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
- **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](/mcp) to connect any external service or tool.

## 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.

## Deployment Options

**Cloud-Hosted**  
Launch immediately at [sim.ai](https://sim.ai) with fully managed infrastructure, automatic scaling, and built-in observability. Focus on building workflows while we handle the operations.

**Self-Hosted**  
Deploy on your own infrastructure using Docker Compose or Kubernetes. Maintain complete control over your data with support for local AI models through Ollama integration.

<FAQ items={[
  { question: "Is Sim free to use?", answer: "Sim offers a free Community plan with 1,000 one-time credits to get started. Paid plans start at $25/month (Pro) with 5,000 credits and go up to $100/month (Max) with 20,000 credits. Annual billing is available at a 15% discount. You can also self-host Sim for free on your own infrastructure." },
  { question: "Is Sim open source?", answer: "Yes. Sim is open source under the Apache 2.0 license. The full source code is available on GitHub and you can self-host it, contribute to development, or modify it for your own needs. Enterprise features (SSO, access control) have a separate license that requires a subscription for production use." },
  { question: "Which AI models and providers are supported?", answer: "Sim supports 15+ providers including OpenAI, Anthropic, Google Gemini, Groq, Cerebras, DeepSeek, Mistral, xAI, and OpenRouter. You can also run local models through Ollama or VLLM at no API cost. Bring Your Own Key (BYOK) is supported so you can use your own API keys at base provider pricing with no markup." },
  { question: "Do I need coding experience to use Sim?", answer: "No. Sim lets you build agents visually by dragging blocks onto a canvas and connecting them, or conversationally through Mothership using natural language. For advanced use cases, the Function block lets you write custom JavaScript, and the full API/SDK is available for programmatic access." },
  { question: "Can I self-host Sim?", answer: "Yes. Sim provides Docker Compose configurations for self-hosted deployments. The stack includes the Sim application, a PostgreSQL database with pgvector, and a realtime collaboration server. You can also integrate local AI models via Ollama for a fully offline setup." },
  { question: "Is there a limit on how many workflows I can create?", answer: "There is no limit on the number of workflows you can create on any plan. Usage limits apply to execution credits, rate limits, and file storage, which vary by plan tier." },
  { question: "What integrations are available?", answer: "Sim offers 1,000+ native integrations across categories including AI models, communication tools (Gmail, Slack, Teams, Telegram), productivity apps (Notion, Google Workspace, Airtable), development tools (GitHub, Jira, Linear), search services (Google Search, Perplexity, Exa), and databases (PostgreSQL, Supabase, Pinecone). For anything not built in, you can use the MCP (Model Context Protocol) support to connect custom services." },
  { question: "How does Sim compare to other AI agent builders?", answer: "Sim is an AI workspace — not just a workflow tool or an agent framework. It combines a visual workflow builder, Mothership for natural-language agent creation, knowledge bases, tables, and full observability in one environment. Teams build agents visually, conversationally, or with code, then deploy and manage them with enterprise governance, real-time collaboration, and staging-to-production workflows." },
