What is HyperWrite?
HyperWrite by OthersideAI is an AI writing copilot and Chrome extension that provides inline predictive typing, drafting templates, and citation-backed research.
HyperWrite is an AI-assisted writing platform created by OthersideAI. It is delivered both as a standalone web application—including a document editor and HyperChat conversational assistant—and as a Google Chrome browser extension. Its core value proposition focuses on contextual writing assistance across web apps such as Gmail and online text inputs. The service incorporates predictive typing (TypeAhead), which offers real-time sentence completions as the user types to reduce typing effort and overcome writer's block. For content creation, tools like AutoWrite, Rewriter, and Summarizer produce new text or refine existing drafts based on user prompts. HyperWrite also includes custom personas to align model tone with specific user styles. For research-heavy workflows, the platform provides Scholar AI, which searches academic databases and scholarly papers to surface factual information accompanied by citations. HyperWrite also lets users create custom AI tools to automate repetitive drafting and content transformation tasks.
Unlike generic chat interfaces, HyperWrite pairs inline predictive autocomplete (TypeAhead) across browser tabs with an academic search tool (Scholar AI) that injects verified citations into drafts.
