HyperWrite Review
An AI writing assistant with a browser AI agent layered on top, using TypeAhead inline autocomplete to suggest, draft, and rewrite text across web apps.
Is HyperWrite Worth It?
HyperWrite is worth it for writers who want AI help inside every browser tab, but the Premium plan caps you at 250 AI messages a month. TypeAhead’s inline autocomplete works in almost any text field, and the Personal Assistant browser agent goes further than most AI writing tools by acting on the web. Heavy users will bump into the message cap on Premium and should weigh Ultra’s unlimited allowance.
About HyperWrite
HyperWrite is an AI writing assistant and personal-AI browser agent built by OthersideAI that suggests, drafts, and rewrites text as you work. It draws on multiple large language models and runs as a Chrome extension across web apps and text fields, generating suggestions inside email, documents, and forms without a separate editor window.
The product comprises four parts: TypeAhead, an inline predictive autocomplete that completes full sentences in any text field; an AI writing assistant chat that drafts, rewrites, and summarizes text on demand; the Personal Assistant, a browser AI agent that navigates websites and fills forms; and a library of hundreds of task-specific AI tools.
Custom Personas let writers train the assistant on their own samples so the tool matches their voice across TypeAhead, chat, and the tool library. HyperWrite gates the Personal Assistant, citations and real-time info, and higher persona counts behind the Premium and Ultra paid tiers.
Is HyperWrite safe and legit?
HyperWrite is safe to use. OthersideAI states that HyperWrite is GDPR- and CCPA-compliant, encrypts data, and does not sell personal information, though no public SOC 2 report is listed. The Personal Assistant is still an early-stage feature and requires confirmation on sensitive actions, so results need review.
