Caret

Caret is a macOS writing assistant that lives at the system level. It continuously observes what is on screen, builds “memories” of ongoing work, and then uses AI to suggest the next sentence whenever the user taps Tab. Instead of opening a separate chat window, it appears directly in existing apps, aiming to feel like native autocomplete across the entire Mac.

What is Caret? Caret is a macOS writing assistant that lives at the system level. It continuously observes what is on screen, builds “memories” of ongoing work, and then uses AI to suggest the next sentence whenever the user taps Tab. Instead of opening a separate chat window, it appears directly in existing apps, aiming to feel like native autocomplete across the entire Mac. Key Features: Systemwide Tab Completion: Offers AI suggestions in virtually any macOS app by pressing Tab while typing. Always-On Context Engine: Continuously reads the screen to build memories so suggestions reflect both current work and recent activity. Personalized Writing Style: Tailors completions to match the user’s tone and phrasing so output sounds closer to how they naturally write. App-Agnostic Presence: Appears as an overlay rather than a separate chat app, staying available inside documents, emails, and chats across the system. Pros Frictionless writing flow: Reduces context switching and keeps writers inside their current app while still receiving AI assistance. High-speed drafting: Tab-triggered completions speed up email, documentation, note-taking, and everyday messaging with minimal extra keystrokes. Consistent voice: Long-lived memories help maintain a recognizable personal or team voice across different tools and contexts.
