## HyperWrite

HyperWrite positions itself as a predictive AI writing assistant that follows you across the web. Through its Chrome extension, it offers TypeAhead suggestions that complete sentences as you type inside Gmail, Google Docs, and other web editors, alongside AutoWrite for generating paragraphs from a short instruction. An email responder drafts full replies from a few keywords, which is a common productivity win for people who live in their inbox.

Beyond the assistant itself, the product ships a large library of pre-built tools covering rewriting, summarization, explaining complex topics in plain language, speeches, and more. Users can also assemble custom AI tools that chain steps together for repeated workflows. HyperWrite Scholar adds a research layer by searching scholarly articles and papers, so generated text can be grounded in current, citation-backed information rather than the assistant's memory alone.

Pricing is subscription-based with a free entry point alongside paid tiers. Paid plans increase the monthly AI message allowance, unlock custom personas that mimic your writing style, and give unlimited TypeAhead suggestions. Higher tiers remove the message cap entirely and provide early access to experimental writing and agent features.

**Pricing & Plans:** Freemium. A free tier introduces the assistant and a limited message allowance; Premium is listed around $19.99/month with 250 AI messages, citations, real-time info, and 3 custom personas; Ultra around $44.99/month adds unlimited AI messages, 10 personas, and early access to experimental features. Annual billing is available at a discount.

- **TypeAhead autocomplete:** Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
- **AutoWrite and rewriting tools:** Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
- **Citation-backed research:** HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
- **Email responder:** Turn a few keywords into a complete, ready-to-send email reply without switching tabs.
- **Custom AI tools:** Build your own reusable AI tools that chain prompts and steps for recurring workflows.

**Strengths:** Works directly inside the browser via a Chrome extension, so no app switching; Combines writing help with citation-backed research in one subscription; Large catalog of ready-made tools plus custom tool building; Essays, emails, and rewrites share one account and one message allowance

**Limitations:** Message caps on lower tiers can be limiting for heavy users; Best autocomplete experience depends on using the Chrome extension; Full capabilities require a paid plan beyond the free allowance

## 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
