HyperWrite

HyperWrite, developed by OthersideAI, has evolved from a sophisticated writing assistant into a comprehensive AI agent platform as of 2026. At its core, it utilizes a multi-model architecture incorporating GPT-4o, Claude 3.5 Sonnet, and proprietary small language models (SLMs) optimized for low-latency text completion and style mimicry. The platform's technical differentiator is its 'Personal Database'—a RAG-based (Retrieval-Augmented Generation) system that indexes a user's previous writings, documents, and preferred communication patterns to ensure every output is contextually and tonally aligned with the individual user. Beyond text, HyperWrite's 'Personal Assistant' agent utilizes computer vision and DOM-tree navigation to execute complex browser-based tasks, such as booking travel, managing CRMs, or performing multi-source market research. In the 2026 market, HyperWrite positions itself as the 'operating system for personal productivity,' bridging the gap between generative content and actionable automation. It targets high-output professionals and enterprises requiring high-fidelity personalization that generic LLMs cannot achieve. Its integration layer spans the entire web via a robust Chrome extension, making AI ubiquitous across Gmail, LinkedIn, Google Docs, and internal web-based ERP systems.
