Overview

Caret is a native macOS AI assistant that lets you press Tab to autocomplete your thoughts in any app on your Mac. It reads what's on your screen and generates contextual completions in your own voice—no need to switch to a separate chat window. Working across 50+ native and third-party apps including Messages, Mail, Slack, Notion, Google Docs, Microsoft Office, Xcode, Terminal, and web browsers, Caret learns your writing style, work, and relationships over time. It builds a local 'second brain' from your sessions, storing memories on your Mac, and sends data to LLM providers under zero-retention commitments.
