Heyday

Heyday is a sophisticated AI memory assistant designed to solve the cognitive load issues associated with information overflow. Its technical architecture centers on a persistent browser-level integration that utilizes advanced natural language processing (NLP) and vector embeddings to index every page, document, and message a user interacts with. Unlike traditional bookmarking tools, Heyday operates as an ambient layer, automatically resurfacing relevant past research, Slack conversations, and Notion pages alongside active Google search results. By 2026, Heyday has positioned itself as the premier 'Context Engine' for knowledge workers, moving beyond simple retrieval into proactive synthesis. It constructs a dynamic knowledge graph from disparate data sources, enabling users to generate summaries and find connections across their digital footprint without manual tagging. The platform's ability to integrate with the professional tech stack—including Google Drive, Slack, and Zoom—allows it to function as a unified organizational memory, significantly reducing time-to-retrieval for critical project data and historical context.
