12 Best Glean Alternatives for Private Enterprise AI Search (2026)

In June 2025, Glean raised $150 million at a $7.2 billion valuation, reflecting its solution to the widespread issue of scattered enterprise knowledge across numerous SaaS tools, which causes employees to waste time finding information. However, its pricing model—starting at over $50 per user monthly with a $50,000-$60,000 minimum annual contract—poses limitations for smaller organizations, leading to the search for alternatives. These alternatives address key concerns such as cost transparency, deployment complexity, and data control, offering varied advantages like open-source self-hosting, custom model training, verified knowledge management, and ecosystem-native AI integration. Notable alternatives include Onyx for self-hosted solutions, Prem AI for enterprise compliance, Guru for verified knowledge, Microsoft 365 Copilot for Microsoft-first organizations, and GoSearch for transparent pricing. The choice of platform depends on specific organizational needs like budget, data control, existing tools, and technical capacity, with options ranging from workflow automation to customer-facing search experiences.
