What TypeBoost does

TypeBoost is a personal AI writing toolkit for macOS that applies custom prompts to selected text inside the app you are already using. The product is built around a simple workflow: select text, trigger the shortcut, choose an action, and get a rewritten result without copy-pasting into another tool.

The homepage positions TypeBoost as a way to stop re-explaining the same writing rules to AI and reuse them as saved actions. The source highlights use cases such as improving emails, writing LinkedIn posts, translating text, cleaning up rough notes, and turning voice input into clearer writing.

Core features

Selected-text actions

Apply saved AI prompts directly to highlighted text, so the writing workflow stays inside the app where the text already lives.

Keyboard shortcut workflow

Trigger actions from a shortcut shown in the demo flow, with control-space used as the example entry point.

Custom prompt actions

Save prompts as reusable actions and customize them for specific writing tasks such as emails, LinkedIn posts, and translations.

Prompt library

Browse a prompt hub with templates for common jobs like improving writing, translating text, fixing grammar, and rewriting for a specific tone.

Voice-assisted workflows

Use voice input and voice-to-text style prompts, including turning voice into clear text or to-do lists, as shown in the homepage examples.

Structured rewrite templates

Work with a range of editing and rewriting templates, including shortening text, formalizing copy, and applying frameworks such as PAS and AIDA.

Common ways to use TypeBoost

Polish and send emails
Draft a message in your email client, then apply an improvement or personalization prompt without leaving the composer. The homepage explicitly shows an email demo and references outreach-style workflows.
Shape social posts
Turn rough notes into a more readable LinkedIn post or social update. The source includes prompts for polishing LinkedIn posts, adding emojis, and rewriting build-in-public style posts.
Translate writing in place
Translate text while staying in the current page or app. The homepage testimonials specifically mention translating from French to English and into Bahasa without switching tabs.
Edit and refine drafts
Clean up messy copy by fixing spelling, grammar, tone, and clarity. The prompt hub includes templates for fixing spelling and grammar, improving writing, and shortening text.
Capture spoken ideas
Use voice input to capture ideas and then convert them into usable text formats, such as clear text or to-do lists. The homepage explicitly mentions voice input and voice-to-text style prompts.
Reuse prompt frameworks
Apply repeatable rewrite frameworks for marketing or structured copy, such as PAS, AIDA, plain language, SEO copy guidelines, or client proposals.
