Head-to-head
Amazon Q Business vs Glean
Both are built for enterprise knowledge sprawl, but one is a broad neutral layer across many systems and the other is an AWS-shaped assistant with a cheaper entry point and tighter platform coupling.

Enterprise search and assistant products only matter once a company has enough internal sprawl to make a single chat box feel inadequate. That is why Amazon Q Business and Glean belong in the same conversation: both are trying to turn scattered company knowledge into grounded answers and usable actions.
They approach that job from different angles. Amazon Q Business is the more AWS-shaped product: permissions-aware, price-sensitive at the entry tier, and designed to sit inside existing identity and Microsoft 365 workflows. Glean is the broader enterprise work AI platform, with a stronger claim to being the neutral layer across many systems.
The choice is simple once you see the split: choose Glean when you need a platform that sits above many tools without favoring one vendor ecosystem, and choose Amazon Q Business when your company is already comfortable with AWS and wants a cheaper, more opinionated enterprise assistant.
The Core Difference
Glean is the better answer for companies that want one cross-system intelligence layer across a messy stack. Amazon Q Business is the better answer for companies that want enterprise retrieval and workflow help, but want it packaged in a more AWS-native way with public entry pricing.
That difference matters because these products fail in different places. Glean gets stronger as the environment gets more fragmented and governance-heavy. Amazon Q Business gets more compelling when the organization already has AWS discipline and a buying committee that wants to see a low published seat price before it commits.
Enterprise breadth
Glean wins here. Its whole pitch is that it can turn Slack, Jira, Google Drive, Salesforce, Microsoft 365, GitHub, and other systems into one permissions-aware knowledge layer. Amazon Q Business is still broad, but it feels like a product deployed from inside AWS rather than a neutral layer sitting above everything.
That distinction is practical. If the organization is already fragmented, Glean is better at meeting that reality head-on. If the company wants a managed assistant that plugs into enterprise systems without becoming the center of the architecture, Amazon Q Business is easier to absorb.
Workflow surface
Amazon Q Business has the edge on immediate day-to-day surface area. Q Apps, plugins, browser-native help, and Microsoft 365 integrations make it easy to put the assistant where employees already work.
Glean is also moving toward agents and actions, but it is still most convincing as a knowledge platform first. That is not a weakness so much as a clue about the product’s center of gravity. If the buyer wants internal search, grounded answers, and a more expansive enterprise context layer, Glean is stronger. If the buyer wants the assistant embedded into existing daily workflows with a lower-friction AWS story, Amazon Q Business is the more direct fit.
Pricing
Amazon Q Business wins decisively on published pricing. As of April 2026, Lite starts at $3 per user per month and Pro at $20, which makes pilots and rollout conversations much easier to start. The catch is that index capacity, consumption, and adjacent AWS services can add real cost.
Glean is the opposite. It is an enterprise sales motion with contact-sales pricing, which is exactly what you would expect from a platform that sells governance, connectors, and rollout support as part of the package. That makes Glean the less convenient option for buyers who want a clean public number and the more natural option for buyers who already know they are shopping for infrastructure rather than a simple subscription.
Privacy and governance
Glean wins here on posture and flexibility. The company emphasizes isolated single-tenant deployments, customer-controlled hosting options, zero-retention agreements with model providers, and a broader enterprise compliance story that includes SOC 2 Type II, ISO/IEC 27001, ISO/IEC 42001, HIPAA, GDPR, and FIPS-backed encryption.
Amazon Q Business is still strong. AWS says customer data is not used to improve the service or underlying models, and browser extension conversations are deleted after 30 days of inactivity and are not indexed back into the company instance. For many buyers, that is enough. But Glean gives security teams more obvious deployment options and a more visibly enterprise-specific control story.
Who Should Pick Glean
Large enterprises with serious SaaS sprawl should start with Glean. If the work lives across Slack, Jira, Salesforce, Microsoft 365, Google Drive, and internal docs, Glean is the better neutral layer because it is built around cross-system retrieval and governance rather than a single vendor ecosystem.
Security-conscious buyers who need the assistant to fit into existing enterprise controls should also favor Glean. The combination of single-tenant options, stronger deployment flexibility, and a more explicit governance story matters when the buying committee includes IT and security from the start.
Who Should Pick Amazon Q Business
AWS-centric companies that want an assistant tied to their cloud and identity stack should pick Amazon Q Business. The product is built to fit that environment, and its permissions-aware approach makes the most sense when AWS is already the operational center of gravity.
Teams that need a lower-cost entry point for enterprise AI should also lean Amazon Q Business. The public Lite and Pro tiers make it easier to justify a pilot, especially when the alternative is a contact-sales process that already assumes a larger platform sale.
Bottom line
This is really a comparison between a neutral enterprise intelligence layer and an AWS-native enterprise assistant. Glean is the stronger product when the problem is organizational fragmentation and you need one platform that can sit above many systems without becoming a vendor-specific compromise. Amazon Q Business is the better fit when the company wants enterprise retrieval and workflow help, but wants a cheaper published entry price and AWS alignment.
If your company is already large, messy, and system-diverse, Glean is the better long-term bet. If your company is AWS-heavy and wants a clearer pilot budget, Amazon Q Business is the smarter buy.
