Compose AI is a lightweight Chrome extension that brings AI writing assistance to every text field on the web. It offers intelligent autocomplete suggestions as you type, much like Gmail's Smart Compose but working everywhere—in Google Docs, Slack, email clients, social media, and more. You can also highlight text and use AI to rephrase, shorten, or expand it. The tool learns your writing style over time to provide more personalized suggestions. What makes Compose AI particularly appealing is that the core functionality is completely free with unlimited usage. For professionals who spend hours writing emails, messages, and documents, Compose AI can significantly speed up daily writing tasks without the complexity of full-featured writing platforms.
