## Chatbox

Chatbox is a multi-model AI client rather than a model of its own. Instead of locking you into a single provider, it connects to the APIs you already pay for — GPT, Claude, Gemini, Grok, DeepSeek and a long list of others — and gives them a single, consistent workspace. Because you supply the keys, your conversations run against your own accounts and quotas, and Chatbox states plainly that it does not sell or share your data. The app ships for Windows, macOS (Apple Silicon and Intel), Linux, iOS and Android, and there is also a browser version, so the same conversations and settings follow you between devices.

The everyday workflow is chat-plus-files. You can drop in PDFs, Word documents, spreadsheets, images and code snippets and ask questions about them, then quietly build a local knowledge base so the app remembers and retrieves your own documents over time. A live web search mode pulls current information for questions where the model's training cutoff is not enough, and the rendering layer handles Markdown, Mermaid diagrams and LaTeX formulas properly, which matters for technical and academic work.

More recently the product has been pushing beyond plain chat with Work Mode, an agentic layer where an assistant can work with your files, search the web, write and preview code and run tools with less babysitting. There is AI image generation for turning prompts into visuals, plus code generation with live preview for quick prototyping. A free tier covers standard use, and paid plans raise limits or add hosted features aimed at heavier users; the desktop app itself can still be used with your own API keys.

**Pricing & Plans:** Freemium: a free tier covers everyday chatting, with paid subscription plans that lift usage limits and add hosted AI capabilities. Bringing your own model API keys keeps costs tied to your provider.

- **Multi-model support with your own keys:** Switch between GPT, Claude, Gemini, Grok, DeepSeek and many other providers in one client by plugging in your own API credentials.
- **File, image and document Q&A:** Upload PDFs, Office documents, images and code, then ask the app to summarise, explain or extract what you need.
- **Local knowledge base:** Store documents locally so Chatbox can recall and answer from your own materials while your data stays on your machine.
- **Live web search and rich rendering:** Pull current results from the web and display answers with Markdown, Mermaid diagrams, LaTeX formulas and code previews.
- **Work Mode agents and image generation:** Let an agent handle multi-step tasks with your files and tools, and generate images directly from prompts.

**Strengths:** Supports many leading models in a single interface, so you are not locked into one provider; Available on Windows, macOS, Linux, iOS, Android and the web; Local knowledge base and clear privacy positioning keep your documents on your device; Handles files, images, web search, code preview, LaTeX and Mermaid out of the box

**Limitations:** Best experience with your own API keys, which means managing separate provider accounts and billing; Model availability and quality depend entirely on which providers you connect; The breadth of modes and settings can be overwhelming for someone who just wants a simple chat window

## OpenCat

OpenCat is a native AI client for Apple platforms, designed so that chatting with an AI assistant feels as smooth as using any well-made Mac or iOS app. Instead of relying on a web interface, it ships as a downloadable application for macOS and a mobile app for iPhone and iPad, with fast, responsive scrolling, native text selection, and system-level integrations that a browser tab simply cannot offer.

Its feature set reaches well beyond a plain chat window. OpenCat supports multiple AI models, so you can route different tasks to different assistants, and includes a prompt library to save the prompts you use repeatedly. Voice chat lets you hold a spoken conversation and hear replies, while Siri Shortcuts let you jump into a chat without opening the app. The keyboard extension is the standout: it puts AI completion and question answering directly into Messages, Notes, Mail, and other apps. On top of that, OpenCat handles text-to-image generation, image-based conversations, translation, and Markdown rendering with bold, italics, links, and code blocks.

Pricing is structured to meet different needs. The free tier covers the essentials — prompt library, Markdown rendering, and access to multiple models — while the one-time OpenCat Pro purchase unlocks the keyboard extension, iCloud sync, Siri integration, and text to speech. A separate Cloud AI subscription provides fast access to multiple hosted models, including voice chat, vision chat, and text to image, for people who would rather not manage their own API keys. The app is built by an independent developer and is not affiliated with OpenAI, Anthropic, or any other model vendor it can connect to.

**Pricing & Plans:** OpenCat uses a freemium model: a free tier plus a one-time OpenCat Pro purchase (about $9.99) and an optional Cloud AI subscription (about $2.99 monthly or $19.99 annually), with a 3-day free trial on cloud plans.

- **AI in every app via keyboard extension:** The keyboard extension brings AI text generation into Messages, Notes, Mail, and any other app on your device, so you never have to switch contexts to ask a question.
- **Voice chat and Siri integration:** Talk to your assistant hands-free and hear spoken replies, with Siri Shortcuts for triggering a chat without opening the app.
- **Multiple models and prompt library:** Switch between different AI models and providers for different tasks, and keep a curated prompt library ready for recurring needs.
- **Image generation, vision chat, and translation:** Generate images from text prompts, discuss photos inside a conversation, and translate text between languages without leaving the chat.
- **Markdown rendering and iCloud sync:** Format answers with bold, italics, links, and code, and sync conversations and settings through iCloud across your Apple devices.

**Strengths:** Native macOS and iOS apps with fluid, responsive performance; Keyboard extension lets you use AI in any app without switching windows; Choice of built-in cloud models or bringing your own API key; One-time Pro purchase option instead of a mandatory subscription

**Limitations:** Some of the best features, like the keyboard extension and Siri integration, require the Pro purchase; Heavy cloud usage depends on a separate subscription or your own API keys and provider limits; Closest competitors offer broader team and enterprise administration features
