TypeBoost is a personal AI writing toolkit that allows users to apply custom AI prompts directly to selected text within any application on macOS. It eliminates the need for copy-paste workflows by enabling users to transform their writing instantly while maintaining their unique voice and style.

The tool features fully customizable prompts that can be saved as reusable actions, voice input capabilities for hands-free operation, and support for multiple AI model providers including OpenAI, Anthropic, and Google. Users can apply AI actions to selected text with a simple keyboard shortcut (Control + Space) and choose from various prompt templates for different writing tasks.

TypeBoost works by allowing users to select text anywhere on their Mac and activate their saved prompts through a quick keyboard command. The system integrates directly with macOS accessibility features to work across all applications, providing immediate AI-powered text transformation without switching between tools or windows.

The benefits include faster writing workflows, improved writing quality, and seamless integration into existing applications. Use cases include writing LinkedIn posts, composing emails, translating text between languages, cleaning up brain dumps, polishing client proposals, and creating marketing copy directly within the applications users already work in.

TypeBoost targets freelancers, founders, indie hackers, marketers, and professionals who need to write efficiently across multiple applications. The tool integrates with macOS and supports 95 languages for translation capabilities, with cloud sync functionality available across devices.
