HyperWrite

HyperWrite (by OthersideAI) is an AI writing assistant plus Personal Assistant and Agent product line that combines AutoWrite, TypeAhead, HyperChat, an AI Document Editor, Scholar AI research, and a Chrome extension that lets an agent take real actions in the browser (Gmail, LinkedIn, shopping, travel). HyperWrite has historically described a partner/API program for its agent, but there is no fully public self-serve API reference - profiled here through the consumer product surface.

HyperWrite is profiled on the APIs.io network. Tagged areas include AI, Writing, Assistant, Agent, and Browser Automation.

HyperWrite’s developer surface includes developer portal, signup flow, pricing, engineering blog, support, YouTube channel, and 12 more developer resources.
