## RewriteBar

RewriteBar solves a very practical problem for Mac users: most writing assistants live in their own editor or browser tab, while real writing happens everywhere — Slack threads, email clients, Google Docs, Notion, Word, WhatsApp and code editors. RewriteBar instead sits at the system level. It grabs your current selection, sends it to a language model with the action you picked, and pastes the result straight back over the original text, so you never leave the app you are working in.

Out of the box it ships with a library of ready-made actions: grammar and spelling fixes that understand full-sentence context, rewriting for clarity, simplification, tone adjustment, humanizing AI-sounding text, summarising to bullet points, fixing broken JSON, converting to title case, turning formal German or French into the informal register, and translation across 500+ languages. On top of those presets you can build your own commands, insert variables, and chain several actions into one workflow — expand, emoji-fy, translate and summarise in a single pass. A side-by-side diff view lets you check exactly what changed before you accept it.

Flexibility is the other selling point. You can bring your own API key from OpenAI, Anthropic, Google, Groq, Mistral, DeepSeek, OpenRouter and dozens more; subscribe to the RewriteBar Gateway to get access to 70 models without managing keys; or run everything through a local model with Ollama, LM Studio or Apple Intelligence for maximum privacy. The app is only around 25 MB, is natively built for macOS, integrates with PopClip, and never stores your text on RewriteBar's servers.

**Pricing & Plans:** Freemium with a free trial, then one-time licences. Try it free with 35,000 credits and no credit card; Standard is $29 one-time (1 device, 35,000 credits, BYOK and local models); Pro is $59 one-time (3 devices, 1 year of RewriteBar Gateway with 3 million monthly credits). Extra devices cost $19 one-time, and the RewriteBar Gateway can be bought separately for $40 per year. Refunds available within 14 days.

- **Works in any application:** RewriteBar captures the selected text system-wide and pastes the improved version back, so it functions in Chrome, Google Docs, Word, Slack, Notion, VS Code, email clients and more.
- **Preset and custom AI actions:** Use built-in commands such as fix grammar, simplify, humanize, summarise, title case, fix JSON, create ASCII art or translate, or author your own commands with variables and prompt libraries.
- **Chain actions into workflows:** Combine several actions to transform text step by step — for example expand, add emojis, translate and rewrite a title in one flow.
- **Cloud or fully local models:** Bring your own API key from major providers, use the RewriteBar Gateway, or keep everything on-device with Ollama, LM Studio, oMLX or Apple Intelligence.
- **Diff view and shortcut-driven flow:** Compare original and rewritten text line by line or word by word, and trigger everything from keyboard shortcuts or PopClip integration.

**Strengths:** Genuinely app-agnostic thanks to system-level text capture; One-time licence options with no mandatory subscription; Strong privacy story with local model support and no server-side text storage; Very small footprint (~25 MB) with native macOS performance

**Limitations:** macOS only, with no Windows or Linux version; Some actions require configuring your own API key, which adds setup work and separate provider costs; Advanced workflows and the 70-model gateway are gated behind the Pro or Gateway plans

## SpellType

Most AI writing tools ask you to change your habits: open a separate chat window, write a prompt, copy the answer back, then rewrite it in your own voice. SpellType takes the opposite approach. It sits inside the applications where writing already happens and offers short, inline completions that you accept with Tab or ignore by continuing to type. There are no model menus, no prompt boxes and no per-app configuration.

Its main differentiator is what it deliberately does not do. SpellType does not request macOS Screen Recording permission, does not take screenshots and does not build a profile of your writing. Suggestions are generated by a small local model on your Mac and never sent to SpellType's servers, which the vendor states means it works offline and keeps sensitive work private. Optional product analytics — limited to counts of active use and suggestions shown or accepted — can be turned off. Because completions finish your thought rather than writing a whole message for you, the output tends to still sound like you.

Setup is a single macOS permission: SpellType uses Accessibility access to offer completions in supported apps, and skips places where autocomplete would not help. It requires macOS 14 Sonoma or later on an Apple silicon Mac, with 16 GB of unified memory recommended, and is designed to stay light on battery so it can be left running. The standard app is free and unlimited for both personal and company use, while bespoke work such as custom models, integrations or deployment is scoped separately under SpellType for Business.

**Pricing & Plans:** The standard SpellType app is free and unlimited — no trial, subscription, suggestion quota, account or license key — and is free for teams too. Customised business work (integrations, deployment, custom models) is quoted separately.

- **Inline Tab autocomplete:** Suggestions appear while you type and are accepted with Tab or dismissed by simply continuing to type, so your flow is never interrupted.
- **Local, private inference:** A small model runs on your Mac. Typed text, prompts and suggestion history are not sent to the vendor, and no screen recording permission is used.
- **Works offline:** Because suggestions are generated on-device, autocomplete keeps working without an internet connection.
- **No prompts or model settings:** There are no prompt boxes, engine choices or per-app tuning steps; after one macOS permission grant, supported apps are handled automatically.
- **Battery-conscious by design:** Built to stay fast and easy on battery during normal writing, so it can remain running all day.

**Strengths:** Genuinely free and unlimited, with no account, quota or license key required; Suggestions run locally, so sensitive writing never leaves the Mac; No Screen Recording permission, addressing a major trust concern with AI typing tools; No prompt writing or model selection, so there is essentially nothing to learn

**Limitations:** Requires an Apple silicon Mac running macOS 14 or later; Intel Macs and Windows are not supported; Locally run models can produce weaker completions than large cloud models on complex writing; Works only in supported writing apps and stays quiet elsewhere, which some users find limiting; There is little per-app control, so you cannot finely tune behaviour for individual tools
