Glean

Glean is an enterprise AI platform that searches and connects company apps, answers questions with permission-aware context, and lets teams build agents, with security and compliance controls aimed at large organizations.

Glean is an enterprise AI platform that connects to the systems a company already runs on, then uses that combined context to answer questions, search across tools and automate work. The homepage lists sources such as Slack, Google Drive, Jira, Confluence, SharePoint, GitHub and Salesforce, and describes more than 275 connections to work apps and data sources. Its pitch is that AI is only useful at company scale when it knows what the business knows. The product is aimed at large organizations rather than individuals. Buyers are typically IT, security and AI program leads who need one assistant that serves engineering, sales, support and HR alike. Customer stories on the site include Booking.com, Zillow, TIME, Ericsson and GCash, which gives a sense of the deployment size involved, from thousands of employees to some teams of a hundred million end users served. In practice, Glean sits between employees and language models. Queries are answered from connected enterprise data, and the platform says it picks the model and reasoning level suited to each task, supporting more than 40 different LLMs. Because context is already indexed and connected, less material has to be sent to the model, which the vendor presents as a way to reduce token spend. Teams can also build agents in natural language, and the customer stories cite agent counts in the thousands. Governance is a central part of the offer. Users see only what they are permitted to see, every query, answer and action can be tracked, and the page lists compliance badges including SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR and TX-RAMP Level 2. Access starts with a demo request, not a self-serve signup. Among alternatives, Glean competes with the AI assistants bundled into productivity suites and with general-purpose chat tools wired to company data. Its distinguishing angle is breadth of connectors, model flexibility and permission handling, in exchange for an enterprise sales process and no published pricing.
