Compose: AI writing assistant that works in every Mac app

Hey Product Hunt! I'm Aayush, the maker of Compose. I kept switching between ChatGPT and my writing apps — copy text, paste into a chat, wait for a response, copy back. It broke my flow every time. I wanted AI writing help right where I type. So I built Compose — a native macOS menu bar app that works system-wide. Here's how it works: - Select any text in any app - Hit a keyboard shortcut - Get instant AI-powered proofreading, rewriting, expansion, or tone changes - The improved text replaces your selection automatically What makes it different: - True native SwiftUI — fast, lightweight, feels like a Mac app should - Works in every app (Slack, Mail, Notion, Xcode, anywhere) - BYOK: bring your own API key for GPT-4, Claude, Gemini, or Groq - Custom prompts and shortcuts for your specific workflows - Voice dictation for hands-free input I'd love to hear what you think. Happy to answer any questions!
