About Compose AI

Compose AI (compose.ai) is an AI-powered writing assistant delivered as a Chrome extension that works across any website where you type — Gmail, Google Docs, LinkedIn, Slack, Notion, and hundreds more. Its core capability is intelligent autocomplete: as you type, Compose AI suggests sentence completions based on your personal writing style, which it learns over time. The platform also generates full emails from short natural-language prompts, rewrites existing text for tone and length, and provides one-click professional email replies.

How Compose AI Works

After installing the Chrome extension, Compose AI activates wherever you type in your browser. Press Tab to accept any autocomplete suggestion. Type // to open the generate-anything command and describe what you want written. To rephrase existing text, highlight it and select the desired tone — friendlier, more professional, shorter, or longer. For emails, open a message and press Option+G (or Alt+G) to generate a contextual reply based on the email thread. The platform continuously learns your writing patterns to personalize future suggestions.

Key Features

  • Autocomplete — suggests sentence completions as you type across all websites; press Tab to accept
  • Generate anything (//) — type // anywhere to generate text, emails, blog paragraphs, or any content from a short description
  • Email reply generation — one-click professional reply that references context from the original email thread
  • Rephrase — reword highlighted text to be friendlier, more professional, shorter, or longer
  • Personalized voice — learns your unique writing style over time to offer style-matched suggestions
  • Grammar correction — real-time grammar and spelling detection across all text fields
  • Multi-language support — works across multiple languages in supported writing styles
  • Cross-platform — Chrome extension, iOS app, and Android app available

Who Should Use Compose AI?

Compose AI is built for busy professionals, executives, and customer-facing teams who write large volumes of emails, Slack messages, and documents daily. Its key advantage over other AI writing tools is that it works everywhere you already type in your browser — no tab switching, no copy-pasting. It is particularly valuable for professionals who need to maintain a consistent professional tone across all communications without manually editing every message.
