Cotypist
Cotypist uses on-device AI to provide smart autocomplete, text prediction, and autocorrect across Mac apps, helping users type faster while keeping writing data private.
Cotypist is an AI-powered autocomplete and predictive text app designed exclusively for Mac computers with Apple Silicon. It runs local language models directly on your device to provide real-time text suggestions while you type. Instead of switching between apps or opening a separate AI chatbot, Cotypist works across your Mac apps with inline ghost-text completions. It can also personalize suggestions based on your writing style, provide AI-powered autocorrect, and apply different instructions to different apps. Its on-device processing makes it suitable for users who want AI writing assistance without sending their typing data to the cloud.
How Cotypist Works
- Install Cotypist: Download and install the Cotypist app on your Apple Silicon Mac, then provide the required system permissions.
- Choose an AI Model: Select and download a local language model based on your Mac's available memory and your preferred balance between speed and accuracy.
- Start Typing Anywhere: Type normally in supported Mac applications while Cotypist analyzes the surrounding text to understand the context.
- Review AI Suggestions: Cotypist displays predicted words and phrases as inline ghost text next to your cursor.
- Accept or Ignore Completions: Press Tab to accept a suggestion or continue typing to ignore and replace it.
- Customize Your Experience: Configure writing preferences, app-specific instructions, model settings, and exclusions to control how Cotypist works.
