Guru vs Glean
A plain-English comparison to help you choose between them.
The split here is philosophy: curate the knowledge or index it as it lies. Pick Guru when answers must trace to content an owner has verified, with automated quality work flagging stale and conflicting material behind them; pick Glean when the estate is too sprawling to curate and the need is permission-aware search and Work AI across every application at once. Verification-led organisations lean Guru; coverage-led ones lean Glean.
Side by side
- Summary
Guru positions itself as the governed knowledge layer for enterprise AI.
- Best for
- Cited, permission-aware answers from a verified knowledge base
- Knowledge Agents that maintain content as well as retrieve it
- Automated conflict detection, duplicate merging and stale-content flagging
- Answers inside Slack, Teams and the browser where questions arise
- Regulated organisations needing SOC 2 Type II, HIPAA and audit trails
- Less suited to
Guru is bought through a sales conversation and packaged to the organisation, which sets the floor: the scoping assumes real knowledge complexity, governance needs and rollout effort. Small teams wanting a lightweight wiki they can adopt this afternoon are not the buyer here, and workspace tools cover that need with far less ceremony. It is also a knowledge layer rather than a helpdesk, intranet or HRIS; systems of record and ticketing stay where they are.
The verification model has limits worth respecting too. AI-generated answers about policy, legal or compliance content are retrieval aids, not authoritative guidance, and verification workflows reduce but do not eliminate the need for owner review of regulated content.

- Guru's governance posture is the pitch. SOC 2 Type II, HIPAA compliance, SSO and audit trails, with permission-aware answers that respect role-based scoping, which is what makes deployment in regulated environments plausible. The discipline to keep is editorial rather than technical. AI-generated answers about policy, legal or compliance content are retrieval aids, not authoritative guidance, and the verification workflows that keep content owned and current reduce but do not eliminate owner review of regulated material. It is a closed, hosted platform, so treat connector scope, answer-audit trails and current security documentation as part of the rollout review.
- Summary
Glean is enterprise search that respects who you are: it indexes the organisation's applications and answers questions with citations, showing each person only what their permissions allow.
- Best for
- Search across the organisation's applications at once
- Permission-aware answers that respect access rights
- Cited answers grounded in company content
- Assistants and agents on the same governed foundation
- Organisations drowning in knowledge sprawl
- Less suited to
Small teams are outside the shape: the connectors, indexing and governance assume enterprise scale, and the procurement matches. Below that, workspace-native AI covers most of the need.
Answer quality also inherits the estate's hygiene: stale documents produce well-cited stale answers.

- Glean indexes your company systems with permissions preserved; its security model is the product, review it accordingly.
By area
Where each one pulls ahead, area by area.
| Area | Pick Guru when | Pick Glean when |
|---|---|---|
| Operations | Guru keeps the operational canon verified so process answers come from SOPs their owners still stand behind | the estate is too sprawling to curate and the real need is search across every application |
| Search & knowledge retrieval | Guru answers from a curated and verified knowledge layer, every answer tracing to content an owner has verified and stands behind | the priority is index-everything work AI across the whole application estate, searching knowledge as it lies rather than as it is curated |
Common questions
What actually differs in how they answer questions?
The provenance of the answer. Guru replies from a curated knowledge base that is actively maintained: content auto-verifies and unverifies as sources change, with conflicts detected, duplicates merged and stale material flagged. Glean replies from a permission-aware index of the organisation's applications with citations, searching knowledge as it lies. Guru answers from what owners stand behind; Glean answers from what exists.
Can a small team try either before committing?
Not really: neither is a self-serve purchase. Guru is a sales-led enterprise product packaged to the organisation, with scoping that assumes real knowledge complexity, governance needs and rollout effort. Glean is likewise bought at organisational scale, with indexing, connectors and governance that assume hundreds of seats and a real IT function. Small teams wanting a lightweight wiki are outside both shapes, and workspace tools cover that need with less ceremony.
Which gives more trustworthy answers on policy content?
Guru is built for exactly that worry: answers trace to verified content, with audit trails behind them. Its own caveat still stands: AI answers about policy, legal or compliance content are retrieval aids, not authoritative guidance. Glean inherits the estate's hygiene instead, so stale documents produce well-cited stale answers. Regulated content needs owner review under either model.
