KeyType AI: Elevating Autocomplete on macOS

Can a small open-source tool redefine productivity on macOS? If you're using KeyType, the answer might be yes. This system-wide AI-powered tab-autocomplete enhances your typing experience across all applications.

KeyType's allure comes from its on-device operation, giving real-time predictions without cloud reliance. Faster response times and privacy concerns are tackled head-on, unlike with solutions like Cotypist.

Key Takeaways

KeyType offers system-wide autocomplete on macOS.
It's open-source and runs entirely on-device.
Provides integration across apps with ghost text.
Acts as a MIT-licensed alternative to Cotypist.
Requires macOS 14+ and recent Xcode.

Exploring KeyType's Features

System-Wide Integration

Unlike autocomplete tools chained to specific apps or ecosystems, KeyType works in any app accepting text input. It monitors the focused text field, predicts continuation via a local LLM, and presents it as ghost text to accept by hitting Tab.
