## Compose AI

Compose AI is built around the idea that most knowledge workers write inside other applications, not inside a dedicated editor. It installs as a browser extension and layers autocomplete on top of ordinary text fields, so sentences finish themselves while you type in email, documents, forms, and chat windows. A generate feature covers the opposite case, where you want a full block of text produced from a short instruction.

A distinctive piece is personalization. Rather than emitting generic robotic phrasing, the assistant studies how you write and suggests phrasing that matches your voice, aiming to reduce the awkward, obviously-AI tone that general chatbots often produce. Because the extension runs wherever text inputs exist, there is no per-app integration to configure and no workflow to migrate.

The product follows a freemium structure. The core extension is free to use indefinitely, and a premium tier adds advanced features including parts of the personalization engine. The company reports that more than 400,000 individuals and over 10,000 teams use it. It is aimed at people who write constantly — sales, support, recruiting, and anyone whose day is dominated by email and documents.

**Pricing & Plans:** Compose AI is freemium. The Chrome extension and core autocomplete are free forever, with a premium subscription unlocking advanced features such as parts of the personalized writing engine. Team plans are available on request.

- **Autocomplete everywhere:** Finish sentences inline in any text field across your browser, from email clients and docs to chat and CRM tools.
- **Generated drafts on demand:** Produce full paragraphs, replies, or documents from a short prompt without leaving the page you are working on.
- **Personalized writing voice:** The engine learns how you write and suggests phrasing that sounds like you rather than generic AI output.
- **Zero workflow change:** Works as a browser extension, so there is no new app to adopt and no per-tool setup for the sites you already use.
- **Team and business use:** Individual and team plans make the assistant available across an organization's shared writing workflows.

**Strengths:** Works inside the apps you already use instead of adding another destination to check; Holds a large user base, with 400,000+ individuals reported, suggesting a mature and stable extension; Free tier covers everyday autocomplete, so value can be tested with no cost; Personalization features target your own tone rather than producing noticeably generic AI text

**Limitations:** Browser-extension form factor means it is limited to environments where you can install extensions; Personalization and advanced generation sit mostly behind the paid tier; Autocomplete suggestions still need review for accuracy in specialised or technical writing

## 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
