If your organization is exploring Glean alternatives, you’re likely searching for an AI-powered enterprise search platform that delivers relevant search results, integrates across every tool, and drives faster decisions.
While Glean remains a popular choice, several enterprise search tools now offer deeper customization, more flexible deployments, and advanced AI and machine learning that better fit modern workflows in sales, customer service, and operations.
Below, we review the top 3 Glean alternatives for 2026 — GoSearch, CoWorker.ai, and Onyx — with a breakdown of their strengths, features, and best-fit use cases.
Why Should You Consider Alternatives to Glean?
Many organizations consider alternatives because:
- Integration Limitations: Glean may not support all your essential knowledge sources, leaving data gaps.
- Customization Needs: Companies may require more flexibility than Glean allows to tailor their search experience.
- Cost Considerations: Budget constraints might make other AI-powered enterprise search options more attractive.
- Limited Support: Feedback is often centered around a delay in response and a lack of priority for bug fixes.
- Federated vs. Indexing: Glean’s search is limited due to its lack of focus on federated search solutions, as indexing is not available.
- No option to test: Glean offers expensive POCs but no free plan to test out the platform. GoSearch offers a free plan.
Exploring platforms like GoSearch, CoWorker.ai, and Onyx ensures you find a user-friendly solution tailored to your organization’s workflows and scale.

Key Features:
