Analyst summary
Glean
Glean is the leading enterprise AI search platform, with full tenant isolation, per-user permission enforcement that mirrors source systems, and deployment options that include private cloud. BYO-LLM support and multi-region residency make it the enterprise-safe answer to 'I want ChatGPT but over our own data.'
The default choice for large enterprises that need AI search with strict permission and residency controls.
Perplexity
Perplexity is a search-and-answer product that combines retrieval with multiple third-party LLMs. Dow Jones and NYP litigation over content scraping, opt-out-only training on user queries, and aggressive growth-over-governance posture all raise material concerns for enterprise adoption.
Useful tool for individual research, but not yet mature enough for enterprise-wide standardization.
