Glean vs Perplexity Enterprise: Which to Pick in 2026?
Both promise to answer questions instead of just returning links, but they pull from very different places. Glean is an enterprise “Work AI” platform that indexes 100+ company apps into a permissions-aware knowledge graph, then runs search and multi-step AI agents on top of it. Perplexity Enterprise is an answer engine that blends your internal data with the live web and cites every claim, at a lower per-seat price. If you mainly need to find and reason over everything scattered across your internal tools, Glean. If you want cited answers that mix company knowledge with a fresh public web, Perplexity.
The One-Sentence Answer
Use Glean if deep, permissions-aware indexing of your internal apps is the point. Use Perplexity Enterprise if you want cited answers that blend internal data with the live web at a lower per-seat price.

When to Use Glean
- Answers live scattered across dozens of internal apps like Slack, Jira, Confluence, Drive, and email
- You need results that respect each employee’s document permissions automatically
- You want AI agents that chain multiple internal steps, not just single answers
- You’re rolling out company-wide search at real scale and can meet the seat minimum
Think of Glean as a search engine for everything your company already knows.
When to Use Perplexity Enterprise
- Your questions often need fresh information from the open web, not just internal docs
- Citations you can click and verify matter more than exhaustive internal coverage
- You want a lower per-seat price and no large seat minimum to get started
- You need a tool that’s fast to deploy without a heavy connector project
Where Your Answers Actually Live Is What Decides It
The real fork is the source of truth. Glean is built to reach deep into your internal stack. It indexes 100+ company apps, builds a permissions-aware knowledge graph, and blends keyword, vector, and RAG retrieval so that “what did we decide about the renewal” surfaces the right Slack thread and doc, filtered to what you’re allowed to see. Perplexity Enterprise leans the other way. Its strength is answering with citations and freshness, comfortably mixing internal material with the live public web, but its internal indexing is lighter than Glean’s and it does less to chain multi-step internal workflows. The price and rollout gap follows from that scope: Glean is enterprise-only with a reported seat minimum and an AI add-on, while Perplexity comes in lower per seat and stands up faster.
Rule of thumb: answers buried across internal apps → Glean; cited answers spanning internal notes and the live web → Perplexity.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
