Helium One vs Glean: shared knowledge for teams
Last updated:
Glean and Helium One both help a company use its own knowledge with AI. Glean is enterprise search with an AI assistant and agents: it connects to many work apps and searches across them. Helium One, built by Neural Arc, is a team AI workspace: the team puts its key SOPs, documents and prompts in one shared place, and every AI task works from that context.
Choose Glean if you are a large company that needs search across hundreds of apps with their existing permissions. Choose Helium One if your team wants a focused, shared knowledge base and prompt library, and an AI workspace it can start using quickly.
