Stack Overflow Unveils Stack Internal, the Trusted Knowledge Intelligence Layer for Technologists in the Age of AI

NEW YORK, NY – November 18, 2025 - Today Stack Overflow announced the evolution of its enterprise knowledge system, Stack Internal, formerly known as Stack Overflow for Teams, and a reflection of our ongoing mission to be the most trusted source for technologists. Built for modern engineering teams, Stack Internal utilizes human insight and AI automation to ensure enterprise knowledge is accurate and accessible, creating an always learning, secure ecosystem that strengthens compliance and accelerates enterprise modernization.

The burden of the creation and maintenance of enterprise knowledge has historically been placed almost entirely on individuals who spend their limited time curating content and managing systems. Add to this that modern developers face tool sprawl, increasing cognitive load, and a pervasive lack of trust in AI tools with 46% of respondents to Stack Overflow’s 2025 Developer Survey not trusting the output of AI, the complexity and responsibility of managing enterprise knowledge has never been greater. Stack Internal now shifts this significant burden from a human only effort to a human and AI partnership that lets technologists focus their energy on building new products and delivering value.

Stack Internal is the go-to space that developers turn to for validated, centralized expertise within their organization, so that teams can increase developer productivity, reduce enterprise risk, and leverage AI with confidence. Users of Stack Internal can trial the following new features:

• Knowledge Ingestion: When it comes to the information that developers need to do their jobs, useful and actionable knowledge is typically scattered within multiple tools within their workspace. Stack Internal’s knowledge ingestion automatically draws specific and high value content from the enterprise tools developers use every day, such as Microsoft Teams and Confluence, and then transforms that knowledge into an easily digestible structured format via AI-powered ingestion. Knowledge Ingestion applies AI to score accuracy and relevance, then pairs that intelligence with scalable human review, resulting in only trusted, verified content in the enterprise knowledge base. Beta users of Knowledge Ingestion include Mercado Libre, Xerox, and Eli Lilly.
• MCP Server: AI initiatives frequently fail because they lack a foundation of human-validated knowledge. Without it, copilots hallucinate, agent outputs atrophy, and teams lose trust in their AI tools. The Model Context Protocol (MCP) Server acts as a secure integration layer that connects AI developer tools—including GitHub Copilot, ChatGPT, and Cursor—to an organization’s context rich, verified knowledge in Stack Internal. With this bidirectional knowledge flow, AI agents pull from and contribute to the enterprise knowledge base, ultimately reducing hallucinations and improving accuracy.
• Stack Internal MCP Server for Microsoft 365 Copilot: Connect Microsoft 365 Copilot in Copilot Studio with your organizational knowledge via the Stack Internal MCP Server. This secure, bi-directional connection allows users to search trusted Q&A or create new questions within Copilot and Microsoft 365 apps. The MCP Server uses OAuth 2.0 for authentication and keeps all data within your organization's Stack Overflow environment.

“This next evolution of Stack Internal represents a turning point in how humans and AI communicate and collaborate,” says Stack Overflow Chief Product and Technology Officer Jody Bailey. “Today’s technologists are facing massive challenges in navigating the enterprise landscape with an increasing amount of unreliable AI-generated information. Powered by AI and human-verified knowledge, Stack Internal ensures that organizational knowledge is not just accurate, but is continuously enriched and lets teams accelerate innovation and unlock new opportunities for learning and productivity.”
