SpellType is an AI-powered writing assistant designed specifically for macOS users who want to write faster without changing their existing workflow. Instead of functioning as a chatbot, SpellType works as an inline AI autocomplete tool that predicts the next words as you type. It supports everyday writing across emails, documents, messaging apps, browser-based editors, and AI tools.
One of SpellType’s standout features is its strong focus on privacy. The AI runs locally on the user’s Mac, meaning autocomplete suggestions are generated on the device rather than in the cloud. The application does not require screen recording permissions, does not capture screenshots, and does not collect writing telemetry. This makes it particularly suitable for professionals handling sensitive information.
Features
Private Local AI Processing
SpellType generates autocomplete suggestions directly on your Mac instead of sending your writing to cloud servers, helping keep sensitive information private.
Inline AI Autocomplete
The AI predicts the next words while you type, allowing you to accept suggestions with a simple Tab key without interrupting your workflow.
Works Across Popular Apps
SpellType supports writing in Gmail, Google Docs, Outlook, Slack, Microsoft Teams, Notes, WhatsApp, ChatGPT, Claude, iMessage, and other supported applications.
No Screen Recording Required
Unlike some AI assistants, SpellType does not request screen recording permissions or capture screenshots, providing an additional layer of privacy.

Because suggestions are generated locally, SpellType continues working even without an internet connection.
