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 [Profile (Markdown)](https://openaitools.app/tool/spelltype.md) ## TypeBoost TypeBoost is a personal AI writing toolkit for macOS and iOS built around one idea: the assistant should live where you write, not in a separate tab. Select text in any app, press a space-based shortcut, choose a prompt, and the improved text is inserted back exactly where you were working. It handles grammar and spelling, smarter email phrasing, translation and rewriting, and it can also take voice input and turn it into clear text. What sets TypeBoost apart is its unopinionated approach. Instead of locking you into one house writing style, it lets you bring your own prompts and choose your preferred models, so you build repeatable workflows that match your voice. On Pro you can draw on OpenAI, Anthropic and Google models. A granular diff view shows every change the AI made, and you can revert individual edits while keeping the rest — so you never lose a sentence you liked. It runs across Apple devices: the macOS app and the iOS keyboard share your prompts and history, so the same workflow follows you from Mac to iPhone. The Free plan provides 50,000 credits to try it, and TypeBoost Pro is $5/month with 1,000,000 monthly credits, premium models and 60-day history. It is a fit for anyone who writes constantly and wants AI assistance without leaving their flow. **Pricing & Plans:** Freemium. TypeBoost Free includes 50,000 credits with no credit card. TypeBoost Pro is $5/month ($60 billed annually) and adds 1,000,000 credits per month, OpenAI, Anthropic and Google models, and 60-day history. Enterprise offers shared prompts, team workflows and priority support. - **AI Inside Every App:** Select text anywhere on Mac or iPhone, run an action, and the improved result is inserted in place — no copy-pasting between tools. - **Custom Prompts & Models:** Bring your own prompts, choose your preferred models (OpenAI, Anthropic, Google on Pro) and build repeatable workflows that sound like you. - **Voice to Text:** Turn speech into clean, formatted text with Voice Mode and AI Dictation without leaving the app you are working in. - **Granular Diff Control:** See every AI change and revert individual edits while keeping the rest, so you keep full control of the output. - **Synced Across Mac & iPhone:** Your prompts and history stay synced between the macOS app and the TypeBoost keyboard on iPhone. **Strengths:** Works inside the apps you already use on Mac and iPhone — no context switching; Fully customisable prompts and model choice keep your own writing voice; Granular diff lets you review and revert individual AI edits; Voice Mode and AI Dictation turn speech into polished text **Limitations:** Limited to Apple platforms — no Windows or Android app; The free tier's 50,000 credits are meant for trying it out, not daily heavy use; Credit budgets and varied model options take a little learning to tune [Profile (Markdown)](https://openaitools.app/tool/typeboost.md) ## Frequently Asked Questions ### How do SpellType and TypeBoost compare in monthly traffic?
