What does SpellType do?
SpellType is a private AI autocomplete for Mac that finishes your sentences in the apps you already use. No prompt boxes, no model menus, no copying text into a separate window. You just keep typing, and when a useful completion appears, you hit Tab to accept it. It works in Gmail, Slack, Google Docs, Outlook, Messages, WhatsApp, ChatGPT, Claude, and several other apps right out of the box.
The key here is that SpellType does not record your screen, send your typing anywhere, or ask you to set up each app individually. Grant one macOS Accessibility permission and it handles the rest. The suggestions run entirely on your Mac using a small local model, so it works offline and barely touches battery life. There are no AI settings to fiddle with — it just quietly suggests the next few words based on what you've written, so your voice stays yours.
This is ideal for anyone who writes a lot of replies, emails, notes, or customer messages throughout the day — support agents, managers, freelancers, or just busy emailers. If you find yourself typing the same kinds of responses repeatedly, or you wish you could get AI help without leaving your current app, SpellType is a low-friction way to save small bits of time on every message. It's not trying to write whole paragraphs for you; it's just giving you a gentle nudge to finish faster.
