What is HyperWrite?

HyperWrite, from the team behind OthersideAI, is best known for its autocomplete: as you type in Gmail, Docs, or almost any text box, it predicts and completes your next words and sentences. On top of that sits a library of writing tools for drafting emails, essays, marketing copy, and documents, plus a chat assistant for longer questions and research.

The Chrome extension is the heart of the product, learning your phrasing over time so suggestions feel personal rather than generic. Dedicated tools handle tasks like explaining text simply, rewriting for different audiences, and generating full drafts from prompts. Power users like the breadth, though the sheer number of tools can overwhelm people who only need occasional writing help.
