Xyne is an AI-first search and answer engine for work, functioning as an open-source alternative to Glean. It connects to workplace applications like Google Workspace, Atlassian, Slack, and GitHub, securely indexes data, and uses retrieval-augmented generation with LLMs to provide conversational answers with source attribution. The system maps relationships across fragmented work data to enable natural language search and discovery across documents, issues, emails, and projects.
