Inline autocomplete while you write
SpellType suggests the next few words while you type, so you can accept a useful completion with Tab or keep typing and ignore it.
SpellType
SpellType is a private AI autocomplete app for Mac that helps you finish email, chat, docs, and other everyday writing faster. It works locally on device, with support for Gmail, Google Docs, ChatGPT, and several native Mac apps.
Private AI autocomplete for everyday Mac writing
SpellType is a private AI autocomplete app for Mac that suggests the next few words while you write. It is positioned for people who spend much of their day in email, docs, chat, notes, and browser-based work writing, and want help without moving text into a separate chatbot.
The product’s main workflow is simple: set it up once on macOS, then type normally in supported apps and accept a suggestion with Tab when it helps. The site emphasizes local processing, no Screen Recording permission, and no prompt boxes or model menus, so the experience stays close to ordinary writing rather than a separate AI workflow.
Core features
Private on-device processing
The product is built around local suggestions on your Mac rather than cloud autocomplete, and the site says writing stays local.
No screen recording requirement
SpellType does not ask for Screen Recording permission and says it does not take screenshots or watch your screen.
Low-impact background behavior
The product is meant to stay usable during normal work and is described as light on battery and easy to leave on all day.
One-time setup for supported apps
After the initial macOS permission setup, SpellType handles supported apps automatically instead of requiring per-app tuning.
Free and Pro usage tiers
The site says free users get the full private autocomplete experience, with Pro removing the weekly accepted-completion limit.
Common ways to use SpellType
Email replies and follow-ups
Use SpellType to speed through routine inbox work by accepting small completions instead of rewriting each reply from scratch.
Work chat and messaging
Let it help with status updates, team messages, and quick back-and-forth in Slack, Teams, Messages, WhatsApp, and iMessage.
Docs, notes, and longer drafts
Use it inside Google Docs or other long-form writing surfaces to reduce repeated typing while keeping the draft in your own app.
Browser-based AI and professional web writing
Type prompts, drafts, or client-facing text in ChatGPT, Claude, or browser-based writing surfaces and use autocomplete without switching tabs or copy-pasting into another tool.
Repetitive workplace writing
Rely on it for repetitive work writing such as meeting notes, customer replies, recruiting outreach, sales writing, and updates where small completions save time.
Pros and Cons
Pros
- Keeps autocomplete local on the Mac instead of requiring cloud prompts.
- Does not require Screen Recording permission, according to the site.
- Works in the apps people already use for everyday writing, including email, docs, chat, and messages.
- Uses a lightweight accept-with-Tab flow that avoids switching tools while drafting.
- Can work offline because suggestions run locally.
Cons
- The supported-app list is focused and appears narrower than a general-purpose AI writing suite.
- The site does not provide a pricing page in the collected sources, so plan details are only partially documented from the homepage.
- Availability depends on supported apps and browser support, so it is not presented as a universal system-wide writer for every app.
