Glean

Glean connects to Slack, Confluence, Jira, Google Drive, Salesforce, GitHub, and 100+ other tools to give employees one AI search and assistant that actually understands company-specific knowledge. Ask something like 'what did the design team decide about checkout?' and it pulls the relevant Slack threads, Figma files, and docs together with context, rather than making you go find each source yourself — which is why it's become one of the most widely deployed enterprise AI tools around.
