## 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

## WriteMage

WriteMage is built around a simple idea: instead of copying text into a chatbot and pasting the answer back, bring the AI to wherever you are already typing. On macOS it runs as a floating panel that sits above your active app like Spotlight, so you can select text, ask for a rewrite or translation, and drop the result straight back into the document. Because it can see the surrounding context, the answers relate to what you are actually working on.

It also has memory. WriteMage keeps track of the conversation and answers with that context, and every chat is saved locally with a label so you can pick up a thread from yesterday. A Prompt Editor GUI lets you tailor the preset prompts and add your own, which turns the app into a reusable toolkit for email drafts, summaries, edits and translations.

On iOS, WriteMage is implemented as a native keyboard extension, which is the mechanism that lets an AI assistant work inside other apps on a platform that sandboxes them. The developer has been notably transparent about the business: it was developed in late 2022, was free during an extended beta, and offers both subscription plans and a one-time lifetime deal. You can either provide your own OpenAI API key for unlimited words or pay to have AI usage managed for you.

**Pricing & Plans:** Freemium-style model with a free beta download and paid plans. Basic plan (about $10-16/month billed yearly at launch sale pricing) has you bring your own OpenAI API key for unlimited words; the Personal plan (about $12-19/month billed yearly) includes managed AI usage, roughly 750,000 words per month. A one-time lifetime deal covering both macOS and iOS was also offered. Confirm current prices on the official site.

- **ChatGPT in any macOS app:** Use ChatGPT without copy-pasting: WriteMage floats on top of whatever macOS app you are in and can read the surrounding context.
- **iOS keyboard assistant:** A native iOS keyboard lets you rewrite, translate, summarize and draft text inside any app in the App Store.
- **Conversational memory and history:** WriteMage remembers the current conversation and answers with that context in mind, and saves chat history locally with labels.
- **Custom prompt editor:** A prompt editor GUI lets you customize the built-in prompts and create your own for recurring tasks.
- **Bring your own API key:** Run on your own OpenAI API key for unlimited words, or let WriteMage manage AI usage with a monthly word allowance.

**Strengths:** Works directly inside any macOS app and any iOS app via the keyboard, no copy-pasting; Context-aware answers and session memory make it useful for real documents, not just chat; Local chat history with labels and no telemetry, even during beta; Bring-your-own OpenAI API key option removes word limits

**Limitations:** The macOS app was still labeled beta (v1.1.4) at the time of review, so it may not be fully polished; In-app purchase to use your own OpenAI API key on iOS costs extra; you also need an OpenAI account; License limits macOS devices (2 on basic, 4 on personal), which is restrictive for teams; Windows, Linux and Android are not supported
