About HyperWrite
HyperWrite is an AI-powered writing assistant and personal productivity platform designed to help users write faster, smarter, and more creatively across any task. Built by OthersideAI (rebranded from HyperWrite), the platform combines advanced language models with a Chrome extension, web editor, and hundreds of pre-built AI tools to assist with everything from emails and blog posts to academic writing and research. The platform integrates context-aware sentence completions (TypeAhead), custom personas that learn your writing style, real-time citations through Scholar AI, and a Personal Assistant that can automate web browsing tasks.

Frequently Asked Questions
What is HyperWrite and how does it work?
HyperWrite is an AI writing assistant that uses advanced language models (GPT-4, Cohere) to help you write faster. It works via a web app and Chrome extension, integrating directly into Gmail, Google Docs, and other writing platforms. The tool offers TypeAhead contextual suggestions, custom AI personas trained on your style, and hundreds of pre-built tools for specific tasks like email writing, summarization, and research.
How much does HyperWrite cost?
HyperWrite offers a free tier with limited credits, Premium at $19.99/month (250 AI messages + 3 custom personas), and Ultra at $44.99/month (unlimited messages + 10 personas). Annual plans save 20%. Students get 50% off with a .edu email.
Is HyperWrite available on mobile?
HyperWrite is optimized for the browser; full functionality requires Chrome, Firefox, Safari, or Edge. Some popular AI tools are available on mobile through the web app, but dedicated iOS and Android apps are not currently offered.
What are HyperWrite's limitations?
HyperWrite excels at short-form content and writing suggestions but can produce surface-level output lacking depth. The writing often feels robotic and requires heavy editing. It only supports English, has limited creative ideation capabilities, and the free tier is very restrictive. It's best used as a co-writing partner rather than a standalone content generator.
How does HyperWrite compare to ChatGPT?
HyperWrite focuses on writing productivity with in-context suggestions and a personalization engine, while ChatGPT is more general-purpose. HyperWrite's TypeAhead and browser integration are stronger for workflow automation, but ChatGPT offers more versatility for creative and open-ended tasks. HyperWrite is better for email/blog assistance; ChatGPT is better for complex reasoning.
What is Scholar AI and how does it work?
Scholar AI is HyperWrite's real-time research tool that searches millions of peer-reviewed academic papers and provides properly cited sources. It's available on Premium and Ultra plans, allowing you to back up your writing with credible research directly within your documents without leaving HyperWrite.
Can I use HyperWrite without the Chrome extension?
Yes. HyperWrite has a web-based dashboard where you can create documents, use AI tools, and access all features. However, the Chrome extension provides superior convenience by letting you use TypeAhead and other features directly in Gmail, Google Docs, Notion, and any website without switching tabs.
