What is TypeBoost?

TypeBoost is a macOS-native AI writing assistant that turns your saved prompts into a personal toolkit you can use inside any application. Instead of copying text between tabs, you select content, press a shortcut, and apply a custom AI action—fixing grammar, rewriting for tone, translating, or generating new copy—all without leaving your current app. It works with your choice of AI model, supports voice input, and learns from your edits over time.

Who it's for

• Freelancers and founders – who write daily across multiple apps and need to maintain a consistent voice without switching tools.
• Non-native English speakers – who want to draft in their native language and get instant, seamless translations or polished English copy right where they work.
• Indie hackers and creators – who rely on fast, repeatable writing workflows for outreach, social posts, and client communication.

Key features

Custom prompts as actions

Save any prompt as a reusable action—fix spelling, apply the PAS formula, translate to English, or write a LinkedIn post. Each action is one click or shortcut away, so you never re-explain your intent to AI.

Works inside any app

TypeBoost operates system-wide on macOS. Select text in your email client, browser, notes app, or design tool, trigger the shortcut, and choose an action. No copy-paste, no tab switching.

Voice input and learning

Dictate ideas on the go and have them cleaned up or expanded. The app also learns from your edits over time, adapting to your style so the output sounds more like you with repeated use.

Model choice and full control

You pick the underlying AI model. Every change is visible and editable—TypeBoost shows you what was altered so you can accept, tweak, or reject it before finalizing.

What stands out

"Saves me like 50x switching to ChatGPT a day."

That quote from a founder captures TypeBoost's core edge: it eliminates the friction of context-switching. Most AI writing tools live in a separate browser tab or app, forcing you to copy, paste, and reformat. TypeBoost stays out of your way by embedding AI actions directly into your existing workflow. You stay in your email, your document, or your design tool, and the AI adapts to you—not the other way around.

Worth checking out if…

You write a lot on macOS and want AI assistance that doesn't interrupt your flow. If you've ever wished you could fix grammar, rephrase a sentence, or translate text without leaving the app you're in, TypeBoost delivers that. It's especially useful if you rely on repeatable writing patterns—cold emails, social posts, client proposals—and want to apply them instantly without re-prompting.
