Glean is a laser-focused enterprise search engine that genuinely earns its place in large organizations drowning in fragmented information across dozens of apps. Its strength is breadth — connecting over 100 data sources and surfacing answers fast. Smartsheet AI, by contrast, is a full work management platform where AI accelerates the actual doing: planning projects, automating approvals, generating summaries, and tracking deliverables across teams. These tools solve different problems. The meaningful difference is scope. Glean helps you find work that already exists; Smartsheet AI helps you execute new work. Glean's trust story is solid but trails Smartsheet AI's exceptional compliance stack, which includes FedRAMP and DOD IL4 — credentials that matter enormously in regulated sectors. Smartsheet AI also has a rare explicit no-AI-training guarantee, which is a genuine differentiator when sensitive business data is involved. Choose Glean if your core pain is information retrieval — your team spends hours hunting for documents, answers, or institutional knowledge scattered across tools. Choose Smartsheet AI if you need a platform to actually manage, automate, and collaborate on business operations. Enterprises in regulated industries should lean Smartsheet AI hard. Organizations already well-organized but knowledge-fragmented are Glean's sweet spot.
