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

Glean, valued at $7.2 billion in 2025, addresses the issue of scattered enterprise knowledge across numerous SaaS tools, but its high pricing model and lack of a free tier or self-service trial make it less accessible for smaller organizations. As a result, various alternatives have emerged, offering different advantages such as open-source self-hosting, transparent pricing, faster deployment, or specialized capabilities. Organizations seek alternatives due to Glean's costly and opaque pricing, deployment complexity, and data control issues, especially in regulated industries. Options like Onyx provide self-hosted solutions with extensive data source connectivity, while Prem AI focuses on custom model training for compliance, and Guru offers verified knowledge management. Microsoft's Copilot integrates AI into Microsoft 365 for ease of use, GoSearch offers budget-friendly, real-time federated search, and Dust enables AI-driven workflow automation. Companies choose based on specific needs such as cost, data control, deployment speed, and integration with existing tools, ensuring that the solution aligns with their organizational constraints and requirements.
