The questions where ChatGPT currently names Google Cloud Search.
If you mean enterprise-wide search across tools like Google Drive, Microsoft 365, Slack, Jira, Salesforce, Confluence, etc., my shortlist for 2026 is:
| Platform | Best for | My take |
|---|---|---|
| Glean | Best overall employee/AI search | ⭐ Top pick |
| Microsoft 365 Search / Copilot | Microsoft-heavy companies | Best if you're already deep in M365 |
| Coveo | Search + customer service/e-commerce | Excellent relevance and personalization |
| Elastic | Highly customizable search infrastructure | Best for engineering-led teams |
| Google Cloud Search / Gemini Enterprise | Google Workspace-centric organizations | Strong native Google ecosystem |
| Guru | Knowledge management + verified answers | Good when governance/curation matters |
| Sinequa | Complex, regulated enterprises | Strong for sophisticated enterprise knowledge retrieval |
Glean is probably the strongest turnkey enterprise search option today. It connects knowledge across business applications, uses AI to synthesize answers, and is designed around permission-aware enterprise access. Gartner currently lists Glean among the leading enterprise AI-search products, with a 4.5/5 rating from 361 reviews. Gartner Gartner
For a typical 1,000+ employee company:
The biggest distinction is whether you want “Google for my company's information” or a developer search engine. Glean is strongest for the former; Elastic is stronger for the latter.
If you tell me your company size, tech stack (Microsoft/Google/Slack/Atlassian/Salesforce), and whether this is employee search or customer-facing search, I can narrow this to the best 2–3 options and compare pricing, connectors, security, AI quality, and implementation effort.
