Product Overview
What is TypeBoost?
TypeBoost is a macOS-native writing productivity tool that embeds directly into your existing workflow. Instead of jumping between your app and a separate AI tool, you simply select any text, trigger TypeBoost with a global keyboard shortcut, and apply your saved prompt actions instantly — right where you're working. It supports multiple AI model providers, voice input, granular accept/reject editing, and cross-device sync, making it a fully customizable personal writing system rather than just another AI assistant.
Key Features
In-App Text Actions
Apply saved prompt actions directly to selected text inside any macOS app via a global keyboard shortcut — no switching tabs or copy-pasting required.
Custom Prompt Library
Build and save your own reusable prompt actions tailored to your tone, style, and tasks. Prebuilt templates are also available to get started quickly.
Voice Mode
Dictate instructions or full content using voice input. TypeBoost converts spoken input into polished text, and also accepts freestyle voice commands on selected text.
Multi-Model Support
Pro users can choose from multiple AI model providers including OpenAI, Anthropic, and Google, giving flexibility to match the right model to the task.
Granular Edit Control
Review every AI-suggested change and accept or reject edits individually, keeping you in full control of your final output.
Cross-Device Sync
Prompts and history sync across Mac and iPhone via the cloud, so your personal writing toolkit follows you across devices.
