OthersideAI was founded in 2020 by Matt Shumer, Miles Feldstein, and Jason Kuperberg. The company is headquartered in New York, New York.


OthersideAI created HyperWrite, a personalized and context-aware AI writing assistant that helps users write anything faster, better, and more accurately. HyperWrite is powered by GPT-3 and similar AI systems, but it personalizes and contextualizes them for each user and each task.


HyperWrite is also a platform where users can create and share their own AI-powered tools and workflows for any web-based task. HyperWrite also makes the AI context-aware, meaning it takes the context of the writing task into account.


HyperWrite has been used by more than a million people to date. In Feb 2023, HyperWrite had nearly 200k monthly active users and the extension has over 100k installs on the Chrome Web Store.
