What is CopilotKit by TawkitAI?
CopilotKit by TawkitAI is the open-source framework and enterprise agentic frontend stack for building full-stack AI copilot applications, generative UI experiences, and chat assistants directly inside real applications. It bridges your application's frontend (logic, state, UI) with any AI backend—whether that's a direct LLM connection, LangChain/LlamaIndex agents, LangGraph, or emerging protocols like AG-UI, MCP (Model Context Protocol), and A2A. The platform enables developers to create production-ready AI copilots that feel native and powerful within their apps, Slack, and Teams.
Key features include Generative UI where AI agents dynamically render rich, interactive UI components across your app as they work; In-app Actions that let agents execute API calls and multi-step workflows directly within your application; Real-time Context Awareness where agents automatically understand application state and user context without manual prompting; and Agent-App State Sync providing bidirectional synchronization between agents and your application. CopilotKit also offers Frontend SDKs for React and Angular, pre-built chat components, Copilot Textarea for AI autocompletion, AI Autosuggestions, Threads+Persistence for automatic state persistence across sessions, and the CopilotKit Inspector for debugging agent interactions in real-time.
CopilotKit is built for developers who want to embed AI agents directly inside their applications—particularly SaaS companies adding intelligent assistants, creative tools enabling co-creation with AI, and any team building agent-native applications. The platform supports any frontend (React, Vue, iOS, Android, Slack, MS Teams, WhatsApp, Telegram) and connects to any agent framework. With over 34.5k GitHub stars and MIT licensing, it's trusted by the majority of Fortune 500s and Global 50 companies including DocuSign and Evergreen Wealth.

Frequently asked questions about CopilotKit by TawkitAI
What is CopilotKit and what does it do?
CopilotKit is the simplest way to integrate production-ready AI copilots into any product. It's an open-source framework (MIT-licensed) that bridges your application's frontend with any AI backend, enabling you to build full-stack agentic applications, generative UI experiences, and chat assistants. The platform connects to any agent framework or model including LangChain, LangGraph, LlamaIndex, and supports protocols like AG-UI, MCP, and A2A.
What is the AG-UI protocol?
AG-UI (Agent-User Interaction) is an open, lightweight, event-based protocol created by CopilotKit that defines how agents, users, and applications stay synchronized. It provides a bi-directional connection between user-facing applications and agentic backends, transforming agents from background processes into transparent, reliable collaborators that are always aligned with the user. The protocol keeps one event stream behind every surface (web, Slack, Teams, mobile).
What frontend frameworks and platforms does CopilotKit support?
CopilotKit supports any frontend including React and Vue for web, iOS and Android for mobile, Slack and MS Teams for team chat, and WhatsApp and Telegram for messaging. It offers official Frontend SDKs for React and Angular with first-class support, hooks, components, and full TypeScript support. The platform enables building once with AG-UI and adapting per channel.
What are Generative UI capabilities?
Generative UI allows AI agents to dynamically generate and render rich, interactive UI components using MCP-Apps and A2UI as they work. Instead of text-only chat, agents can create engaging visual experiences like flight cards, weather cards, tables, and custom components that adapt to each user's journey. This goes far beyond standard chatbot experiences by turning conversations into actions with visual feedback.
How does CopilotKit handle application state and context?
CopilotKit provides Real-time Context Awareness where agents automatically stay aware of application state, user context, and environmental changes without manual context management required. It also offers Agent-App State Sync with bidirectional state synchronization—agents read app state, the app reacts to agent actions, and everything stays in sync. Copilot Readable State enables copilots to read and understand application state naturally.
What pricing tiers does CopilotKit offer?
CopilotKit offers 4 tiers: Developer (Free forever, 1 seat, 200 threads, 3-day retention, 1 GB storage), Pro ($39/developer/month up to 5 seats, 5,000 threads, 5-day retention, 10 GB storage, includes all Premium features), Team ($500/month flat with 5 seats, 25,000 threads, 14-day retention, 100 GB storage), and Enterprise (custom tailored pricing with SSO, On-prem Cloud, internationalization, SLA). All paid plans are monthly billing.
Can I use CopilotKit with my existing agent framework?
Yes, CopilotKit connects to any agent framework or model. It supports direct LLM connections, LangChain, LangGraph, LlamaIndex agents, and emerging protocols like AG-UI, MCP (Model Context Protocol), and A2A. You can bring your own agents, models, frameworks, and collaboration surfaces. The platform's first-party integrations work with the leading agent stacks.
What is CopilotTextarea and how does it work?
CopilotTextarea is a powerful AI autocompletion feature that serves as a drop-in replacement for any standard textarea in your application. It provides autocompletion, insertion, and editing capabilities powered by AI, and is designed to support all Copilot Portal integrations. This enhances user input experiences with intelligent suggestions beyond typical text input.
How do I get started with CopilotKit?
Start with a single command using npx copilotkit@latest create or npx copilotkit@latest init for existing apps. Get a free Copilot Cloud API key (or self-host), wrap your app with the CopilotKit component importing from @copilotkit/react-core, add a copilot chat or sidebar component using @copilotkit/react-ui, and start defining actions/tools. You can get started in minutes with simple, powerful APIs and follow the quickstart tutorial.
What enterprise features does CopilotKit provide?
Enterprise plans include custom tailored pricing with SSO (Single Sign-On), On-prem Cloud deployment options, Internationalization support, Accessibility support, onboarding consultation, dedicated Slack support with SLA (Service Level Agreement), and full control over deployment. Enterprise also gets early access to cloud hosting, premium features like Guardrails and RAG, and managed hosting options for mission-critical needs.
