The enterprise AI race is heating up: Microsoft bundles Copilot into Office, Google pushes Gemini into Workspace, and OpenAI & Anthropic sell directly to enterprises. Amid the noise, Glean is taking a different approach — building the intelligence layer beneath it all.

Instead of just a chatbot, Glean maps enterprise context across Slack, Jira, Salesforce, and Google Drive, allowing AI models to understand who employees are, what work they do, and how information flows. Its Assistant combines proprietary and open-source models (ChatGPT, Gemini, Claude) but the real value lies in its connectors, governance, and model abstraction layer.

This lets enterprises switch between models, enforce permissions, and verify outputs line-by-line, preventing hallucinations — a foundation that keeps companies from being locked into a single AI provider or workflow suite.
