What Compose AI is
Compose AI is an AI writing assistant from Compose AI for producing and completing text while writing emails, documents, and chats. Its Chrome plugin autocompletes across tools, and the maker specifically identifies Google Docs and Gmail for text generation. Typing // in those apps can request ideas or draft text. Users can highlight existing writing and ask for alternate phrasing, or provide a few words to generate a complete email reply that refers to the original message. Compose AI says it learns a user’s writing voice to suggest personalized phrases. The product is available as an extension and on the web, with a Chrome Web Store download. Listed use cases include copywriting, blogging, recruiting, and social media. Pricing is freemium: the Free plan is free for a Chrome plugin, free to use forever; Premium has no listed price.
