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) ## Open WebUI Open WebUI is an open-source, self-hosted interface for working with AI models. Instead of renting access to a single vendor's chatbot, you run the interface on your own hardware or cloud tenancy, then connect whatever models you want: local runtimes such as Ollama, OpenAI-compatible endpoints, Anthropic, or a mix of local and remote. Everything a team produces — conversations, prompts, models, skills and tools — stays in an environment you administer. The platform has grown well beyond a chat window. Retrieval-augmented generation, web search, document understanding, voice input and output, and vision are built in, and Python tools, functions and pipelines let developers script custom behaviour and share it. On the operations side it offers enterprise features such as SSO, role-based access control, audit logs, data residency options, and on-premises, hybrid or fully air-gapped deployment for regulated environments. White-labeling and custom branding are also available for organizations that want their own look. Open WebUI is distributed free of charge under an open-source license and can be installed with a single pip or Docker command, with no account required to get running. A separate enterprise offering is available for organizations that want commercial support, compliance guarantees and managed rollout help, which is quoted on contact. A large community maintains a public hub of prompts, models, tools and functions, so much of what teams need is already shared and ready to install. **Pricing & Plans:** The core platform is free and open source, installable via pip or Docker with no account required. An enterprise tier with support, compliance and deployment assistance is quoted on contact. - **Any Model, Any Endpoint:** Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface. - **Retrieval and Search Built In:** RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources. - **Python Tools, Functions and Pipelines:** Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others. - **Enterprise Controls:** SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements. - **Community Hub:** Browse and install prompts, models, skills and tools contributed by hundreds of thousands of community members. **Strengths:** Free and open source with no account needed to install; Works with local and cloud models through a single interface; Strong privacy posture: your data and models stay on your infrastructure; Extensive enterprise features including SSO, RBAC and audit logs **Limitations:** Self-hosting requires you to handle servers, updates and backups; Some enterprise capabilities and support sit behind a paid, quote-based tier; Feature depth means a learning curve for non-technical administrators; Local model performance depends heavily on your own hardware [Profile (Markdown)](https://openaitools.app/tool/open-webui.md) ## Frequently Asked Questions ### How do ChatKit and Open WebUI compare in monthly traffic?
