If you have searched for glean alternatives in 2026, you are typically doing one of three things. You are scoping enterprise AI search and the 100-seat minimum or six-week procurement cycle does not fit your timeline. You are evaluating Guru and want to understand whether the card-based model is the right shape for your knowledge. Or you are a UK or EU regulated buyer whose compliance function will not approve a US-controlled inference layer, and "sovereign alternatives" is the term you have been told to look for. The three motivations lead to different answers, and the products that solve each are not interchangeable.
This guide explains the structural differences between Glean, Guru, and the smaller category of sovereign alternatives that has emerged for regulated buyers in the UK and EU. It sits under our wider 2026 enterprise search comparison guide, which covers the full vendor landscape and procurement workflow. It is written for CTOs and CIOs who are mid-evaluation, already familiar with the basic AI-search pitch, and now trying to work out which of three different products is solving the problem they actually have.
Glean alternatives: what you are really comparing
The vendors that show up when you search for Glean vs Guru vs sovereign alternative are not three versions of the same product. They are three different product shapes, each suited to a different procurement question.
Glean is a universal-connection enterprise AI search tool. It builds a knowledge graph across the document estate, integrates deeply with sources like SharePoint, Google Drive and Confluence, and is designed for organisations with at least 1,000 seats and a dedicated procurement function. The architecture is mature; the price floor and rollout time match the customer base.
Guru began as a card-based knowledge platform and has repositioned around indexing connected sources. It now states that it unifies knowledge from Drive, SharePoint, Slack, Zendesk, Confluence and CRM systems, that content retains its original permissions, and that results come back verified and backed by clear sources. Its verification workflows, increasingly automated, are the part of the product with the longest track record. Like Glean, it is US-controlled and sales-led.
Sovereign alternatives are the newer category. They take the curation and cross-source-search architecture seriously and add a UK or EU contractual jurisdictional control over the AI processing layer that the larger US-headquartered vendors do not offer. AnswerVault sits in this category. The category is small but is the right shape for buyers whose regulatory exposure makes a US-controlled inference step unacceptable.
The first job for a buyer is to identify which question they are actually asking, then evaluate vendors within that shape. We unpack the same lens at a category level in our enterprise AI search guide for AI organizational knowledge.
Glean and Guru are different products
The most useful framing for a Glean-vs-Guru evaluation is that they are not really competitors. They are products from different category traditions, both of which now describe themselves as AI knowledge tools. The structural differences are large enough that for most teams, the question "Glean or Guru" is mis-asked.
Glean is built for enterprise scale
Glean's connector coverage is broad, the knowledge graph traverses entity and document relationships, and the customer success motion is built for multi-thousand-seat rollouts. The 100-seat minimum and £40 to £50+ per-user-per-month price point reflect that customer base, as does the typical 3 to 6 week enterprise rollout cycle. Pricing is not published; you go through sales. None of this is a flaw; it is a deliberate fit for the customers Glean is designed to serve. We cover the structural details in our AnswerVault vs Glean comparison.
Guru is built around verified knowledge over connected sources
Guru's distinguishing idea is verification: content carries an explicit trust signal, with expert review and, now, automation that re-checks it. That idea originally required manually authored cards. It no longer does, because Guru indexes connected document sources directly. Guru does not publish per-seat pricing; its pricing page describes a tailored investment based on organisational scale and AI maturity and directs buyers to sales. Where it leaves a gap for UK and EU regulated buyers is jurisdiction: like Glean, it is US-controlled with no sovereign deployment option. The current comparison is in our AnswerVault vs Guru page.
Where each loses to a different category
Glean loses when the seat minimum or the sales cycle is the binding constraint rather than the product. Guru loses when a buyer needs to see a price before opening a procurement conversation. Both lose to a sovereign alternative when the buyer's regulatory exposure cannot tolerate a US-controlled AI processing layer, which neither offers a way around.
Where sovereign alternatives fit
The third category exists because UK and EU data residency is not the same as UK or EU contractual jurisdictional control over the AI processing layer. A platform whose model and inference infrastructure are operated by a US-headquartered company creates a residual exposure that residency alone cannot resolve. For most buyers this does not matter. For regulated buyers in financial services, public sector, healthcare, and certain industrial sectors, it is the constraint that narrows the shortlist most aggressively.
Sovereign alternatives, as a category, take this constraint seriously. The architectural commitment is that the AI processing layer sits inside the same jurisdictional boundary as the data, with contractual provisions that make that boundary defensible to a regulator. Neither Glean nor Guru offers this today.
The category is small enough that buyers genuinely have to read product documentation. The shortlist for UK regulated buyers in 2026 narrows quickly once "non-US AI processing layer" is the filter.
Side-by-side: Glean vs Guru vs sovereign alternatives
The matrix below compares the three categories on the dimensions that matter to a buyer who is mid-evaluation. Vendor-specific figures for Glean and Guru come from AnswerVault's published Glean comparison and Guru comparison pages.
| Dimension | Glean | Guru | Sovereign (AnswerVault) |
|---|---|---|---|
| Minimum seat count | Not published (reported ~100) | Not published | From 1 user (free), 5 (Pro) |
| Price per user / month | Not published (reported £40 to £50+) | Not published | £7 (Pro), £14 (Business) |
| Self-serve signup | No | No | Yes |
| Time to first answer | Weeks | Connector setup time | Under an hour |
| Indexes existing documents natively | Yes | Yes | Yes |
| Source citations | Yes | Yes | At sentence level |
| Web, Teams, Slack | Yes | Yes | Yes (plus CLI, API) |
| Governed, curated document sets | Partial | Yes (cards as curation) | Yes (named SME approval) |
| External access for contractors and partners | No | No | Yes |
| Sovereign (non-US) deployment | No | No | Yes (Enterprise tier) |
The table is opinionated; vendors will dispute individual cells, often with reason. Glean's knowledge graph is genuinely strong; Guru's verification model is mature and now runs over connected sources rather than hand-written cards. Corrected 24 September 2026: an earlier version of this table stated that Guru required content to be re-authored as cards, had no knowledge graph, and cited only at card level. That was out of date and has been withdrawn. The differences that survive are commercial and jurisdictional.
How AnswerVault fits the sovereign alternatives category
AnswerVault is a governed AI knowledge layer designed around the same cross-source knowledge-graph architecture that Glean operates at, applied at a price point and procurement model that does not require a 100-seat commitment, and with a sovereign tier that addresses the constraint Glean and Guru do not.
The product is structured in three tiers. Pro is £7 per user per month with a 5-user minimum. Business at £14 per user per month adds SSO/SAML, API access, data residency, and per-query audit trails. Enterprise sovereign is UK-controlled, contractually outside the jurisdictional reach of the CLOUD Act; for the Enterprise tier specifically, the AI processing layer sits inside the sovereign boundary, not just the data-at-rest layer. Catapult CX Ltd, AnswerVault's operating entity, is certified to ISO 27001, and AnswerVault's ISO 42001 certification is underway; full attestation detail and the trust documents procurement teams need are on our security page.
AI is included in every plan. There are no per-query usage charges, no separate API key requirements, and no need to bring your own model. Customer data is never used to train AI models, by AnswerVault or by our foundation-model providers. The web chat surface is the default, with Microsoft Teams, Slack, CLI, and API available as additional surfaces.
For buyers actively evaluating Glean, AnswerVault is the product designed to run in parallel during the weeks Glean takes to produce a quote. For buyers evaluating Guru, the honest difference is commercial rather than architectural: published pricing, self-serve signup and a free tier against a sales-led process. For UK and EU regulated buyers, AnswerVault is the alternative that does not require accepting a US-controlled AI processing layer, and that is the difference that decides most regulated shortlists.
Next steps
If you are mid-evaluation, the most useful first move is to pick a single document source (a SharePoint policy library, a Confluence wiki, or a Google Drive folder of contracts) and connect it to AnswerVault to see real answers from your real documents. That comparison tells you more in an hour than another round of vendor demos will tell you in a week.
