Why people consider alternatives to Glean

Glean is AI-powered enterprise search that connects all your company's knowledge. Search across Google Workspace, Slack, Confluence, and 100+ apps from one place. AI understands context and permissions, surfacing only what you should see.

Teams most often switch away when one of these starts to bite:

Pricing at scale as usage or premium tiers add up.
Missing integrations with the rest of your stack.
Performance or scale limits as your needs grow.
A specific feature gap you have hit in knowledge base.
