Compose AI

What is Compose AI?

Compose AI is a Chrome extension that adds AI writing help to the sites you already use. Type // in a text field, describe what you want in a few words, and it produces a paragraph in seconds; you can also let autocomplete finish sentences as you go, or rephrase, reword, shorten and expand text you have written. The site says it learns your voice so suggestions sound like you, and it works across tools such as Gmail and Google Docs without opening a separate editor. Typical jobs include recruiting outreach, copywriting, blog drafts and social media posts for LinkedIn and Facebook. The company states that your text is used only to produce completions and is never sold. The plugin is described as free to use, with a premium version that adds advanced features including some personalization options. The vendor reports 10,000+ teams and 400,000 people as users, and the vendor lists no premium price.
