Glean

Glean acts as a centralized brain for your company, allowing you to search across every app your team uses—from Google Drive and Slack to Jira and Salesforce. Instead of wasting hours hunting for documents or asking colleagues for links, you can find exactly what you need with a single search bar that understands your company's specific language and relationships.

You can also use its generative AI capabilities to summarize long documents, draft emails based on internal data, and get instant answers to complex questions. It respects all existing permissions, so you only see information you already have access to. It is designed for mid-to-large organizations that need to eliminate digital friction and improve employee productivity by making internal knowledge easily discoverable.
