Rather than a subscription to a hosted assistant, you bring an API key and ChatKit handles the interface layer: streaming responses, conversation history, and a set of productivity features layered on top of the raw chat. The feature set focuses on practical everyday use. Prompt templates let you save and reuse frequently used instructions, bookmarks keep important exchanges close at hand, and real-time streaming keeps replies feeling immediate. Voice input supports dictation, while optional web search and URL fetching let the assistant pull in information from a link you paste. Because you supply the API key, usage costs are billed by your model provider rather than bundled into the tool. ChatKit is an independent product and is not affiliated with or endorsed by OpenAI. **Pricing & Plans:** ChatKit is positioned as a paid client, with model usage billed separately by your own API provider under a bring-your-own-key model. - **Bring-your-own API key:** Connect your own OpenAI API key so you control model choice, spend and data flow rather than paying a bundled subscription. - **Real-time streaming chat:** Responses stream token by token, keeping long conversations responsive and easy to follow. - **Prompt templates:** Save reusable prompts so repetitive tasks take one click instead of retyping the same instructions. - **Voice input and bookmarks:** Dictate prompts by voice and bookmark the conversations or answers you want to return to. - **Web search and URL fetching:** Let replies draw on live web results or the contents of a specific page you link to. **Strengths:** You control model access and spend through your own API key; Prompt templates and bookmarks speed up repeated workflows; Voice input plus web search and URL fetching in one interface; Independent client, so no vendor lock-in on model choice **Limitations:** Requires an API key and comfort with API billing; You pay your model provider separately from the client; A thinner feature surface than full hosted assistant platforms [Profile (Markdown)](https://openaitools.app/tool/chatkit.md) ## CopilotKit CopilotKit has grown from a simple React component library into what its team calls an enterprise-ready frontend stack for agents. The core idea is unchanged: instead of sending users to a third-party chat window, you drop agent experiences straight into your own interface so the assistant can read live application state, render real charts, forms, or tables with your own components, and trigger actions through your APIs and MCP tools. The platform is organized around three layers. The first is a component and SDK layer covering React, Angular, Vue, and native mobile targets, offering pre-built chat UIs as well as fully headless primitives for teams that want complete visual control. The second is a protocol layer centered on AG-UI, an open, bi-directional connection between a user-facing app and any agentic backend, with connectors for frameworks such as the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, and Mastra. The third is an intelligence layer that captures in-app and in-chat interactions, lets you define learning containers per user, group, or organization, and pushes improvements back into agent skills so quality rises with usage. Beyond the developer toolkit, CopilotKit ships channels such as Slack, Teams, and WhatsApp, template starting points for use cases like company knowledge bases and customer support, and deployment options ranging from self-hosted installs to Copilot Cloud. Its adoption among large enterprises and a large open-source community make it one of the more established options for teams that need agents embedded in the product rather than bolted on beside it. **Pricing & Plans:** CopilotKit offers a free open-source tier and a free getting-started path for developers, plus paid cloud and enterprise plans, including self-hosting options. Exact plan prices are listed on the official pricing page. - **Pre-built and headless UI components:** Ship a working copilot UI in minutes with drop-in components for React, Angular, Vue, iOS, and Android, or go fully headless for total control over rendering. - **AG-UI protocol and framework connectors:** A general-purpose bi-directional link between your app and any agent backend, with integrations for the OpenAI Agents SDK, Claude Agent SDK, LangChain, Google ADK, AWS Strands, Mastra, and many more. - **Generative UI inside your product:** Agents return real UI — charts, forms, tables, and approval prompts rendered with your own design system on the same screen the user is already working in. - **Shared state, frontend tools, and HITL approvals:** Let agents read and write application state, call your frontend functions, and pause for human approval before sensitive actions are executed. - **Self-learning intelligence and observability:** Captured interactions feed learning containers at the user, group, or organization level, while product analytics show where agents succeed and where users struggle. - **Multi-channel deployment:** Deploy the same agent stack to your web app, Slack, Teams, WhatsApp, iOS, and Android with consistent behavior and audit trails. **Strengths:** Open source with a large developer community and active framework coverage; Works with many agent backends through the open AG-UI protocol, avoiding vendor lock-in; Genuinely rich frontend capabilities: generative UI, shared state, frontend tools, and human-in-the-loop approvals; Self-hosting and on-premise options plus enterprise certifications for regulated teams **Limitations:** Aimed at developers, so non-technical users cannot build with it out of the box; The breadth of SDKs, protocols, and cloud products means a real learning curve; Advanced enterprise features and managed cloud come at a cost, and pricing is quote-based [Profile (Markdown)](https://openaitools.app/tool/copilotkit.md) ## Frequently Asked Questions ### How do ChatKit and CopilotKit compare in monthly traffic?
