## ChatKit

ChatKit is a browser-based interface for talking to large language models using your own API credentials. 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

## Use AI

Use AI positions itself as a single AI workspace rather than yet another chatbot. Instead of paying for three or four separate subscriptions and remembering which model is best at what, you get a unified chat surface where Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM and Meta models all live behind one prompt box. The company is explicit that it simply provides access to third-party models and is not affiliated with any of the providers, so what you are buying is convenience and consolidation rather than a proprietary model.,Around that core chat there is a fuller productivity layer. You can create documents, PDFs, slide decks and spreadsheets from natural-language prompts, generate images with current image models, and run Deep Research jobs that read across dozens or hundreds of web sources to produce cited reports. Projects and knowledge bases keep related conversations and files together, a file library stores your uploads, and 100+ app connectors let the assistant pull in or act on data from tools you already use. Memory and context are carried between sessions, scaling from a limited allowance on the free tier to maximum on Max.,Pricing is straightforward and published: a genuinely usable free tier with no credit card, Pro at $19.99 per month, and Max at $116.99 per month with 5x the usage allowance, maximum reasoning effort and access to the most exclusive models. Premium model usage is metered by a daily-applied monthly allowance, with an unlimited 'Use AI Instant' chat mode available on paid plans under fair use. If your work involves constantly switching between frontier models, that consolidation is the main draw.

**Pricing & Plans:** Freemium with a free trial-style free tier. Free: $0 with generous everyday chat, limited web search and web, iOS and Android access, no credit card required. Pro: $19.99/month (billed quarterly at $59.97) for unlimited Use AI Instant messaging, premium model access, projects, image generation and Deep Research. Max: $116.99/month (billed quarterly at $350.97) with 5x the usage allowance, maximum reasoning and Deep Research. Prices vary by country and promotion.

- **Many frontier models in one app:** Switch between Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, GLM and Meta Muse models without juggling separate subscriptions.
- **Switch models mid-chat:** Start a conversation on a fast model and hand the same thread to a stronger reasoning model when the task gets harder, keeping context intact.
- **Deep Research with citations:** Run multi-source research that reads up to 200 sources on Pro and up to 1,000 on Max, returning structured reports with references.
- **Documents, slides and sheets:** Create PDFs, slide decks and spreadsheets directly from a prompt, and generate images with leading models such as Nano Banana and GPT Image.
- **Connectors, projects and memory:** Link 100+ external apps, organise work into projects and knowledge bases, and keep long-term memory and context across sessions.

**Strengths:** One subscription and one interface replaces several separate model subscriptions; Free tier is genuinely usable with no credit card required; Model switching mid-conversation keeps context when you escalate to a stronger model; Built-in document, slide, sheet and image generation alongside chat

**Limitations:** You are limited to whichever models the platform has integrated; you cannot plug in arbitrary API keys for every model; Premium model access is metered by a monthly allowance, so heavy users on Pro can run out; Because it resells frontier models, availability of specific named models can change without notice; No self-hosting or on-premise option for teams that need data to stay in-house
