What is Compose AI?
Compose AI is a writing assistant that works as a browser extension, mainly for Chrome. Once installed, it offers autocomplete suggestions while you type in emails, documents and chat windows across different websites and tools, so you do not have to switch to a separate editor.
The tool is built to reduce typing time. It can generate longer text from a prompt, complete sentences as you write, and learn your writing style over time to suggest phrases that sound like you. The site states it is meant to cut writing time, and the homepage claims a 40% reduction, though this is the vendor's own figure.
