AI writing assistant with autocomplete, research, and a Chrome extension
Context-aware sentence completions appear as you type in Gmail, Google Docs, and other sites through the Chrome extension.
Generate a paragraph from a short prompt or rewrite existing text in a new tone while preserving meaning.
HyperWrite Scholar searches millions of scholarly articles so drafts can include factual, properly cited information.
Turn a few keywords into a complete, ready-to-send email reply without switching tabs.

Fill RFPs and security questionnaires anywhere online with AI answers from your content library
Work inside the portal you were already sent, from SAP Ariba-style vendor portals to plain web forms, and inject answers without copying between documents.
Pull from your organization's approved answers and let AI draft or match a response to each question, cutting down manual typing.
Responses come from your centralized content library, so answers stay consistent and on-brand across every submission.
Because you never leave the questionnaire page, you spend time reviewing instead of shuffling between the platform and the portal.
