PricingFrom ~$50/user/mo, ~$50k-60k minimum contract

Editor's takeGlean unifies search across more than 100 enterprise apps using an Enterprise Graph that strictly inherits source permissions. It raised $150 million at a $7.2 billion valuation and holds SOC 2 Type II and HIPAA certification. Pricing is not public, and mandatory support fees run about 10% of annual contract value.

How much does Glean cost?

Pricing is not public, but reports cite about $50 a user monthly with a minimum contract around $50,000 to $60,000 a year, according to a third-party pricing analysis.

Does Glean enforce data permissions?

Yes. It strictly inherits permissions from source applications, so users only see search results for content they are already authorized to access, according to Glean's own documentation.

PricingCustom Search Unit pricing, semantic ranker $1/1,000 requests

Editor's takeAzure AI Search scales to 24 billion documents per index, combining full-text, vector and hybrid retrieval. Its semantic ranker applies Microsoft's deep learning models, though only to the top 50 results. Pricing follows a Search Unit model that stays transparent but climbs quickly at enterprise scale.

How many documents can Azure AI Search handle?

Up to 24 billion documents per index on standard tiers, with dynamic throttling under heavy load rather than fixed rate limits.

Does Azure AI Search's semantic ranker cover all results?

No. It reranks only the top 50 results from the initial retrieval, which can limit relevance for deep research queries.

PricingCustom quote, consumption-based on query volume

Editor's takeCoveo grounds generative AI answers in a unified enterprise index, a feature it calls Relevance-Augmented Retrieval. Gartner has named it a Magic Quadrant Leader for search and product discovery two years running. Setup leans technical, and consumption-based pricing makes total cost difficult to forecast at enterprise scale.

Is Coveo HIPAA compliant?

Yes. Coveo holds ISO 27001, ISO 27701, SOC 2 Type II certifications and is HIPAA compliant, with encryption at rest and in transit.

How is Coveo priced?

Pricing is not public. Coveo uses a consumption-based model tied to query volume, which some users say makes costs hard to predict at scale.

Editor's takeAha! draws a clear line on data privacy, contractually blocking AWS, Google, and OpenAI from training on customer content. The search itself only covers what lives inside Aha! Knowledge, so Confluence content needs a one-way import rather than a live connection.

Does Aha! use my data to train AI models?

No. Aha! explicitly states knowledge base content is not used to train AI models, with contractual bans on its AI vendors doing so.

Can Aha! search live Confluence content?

No. Confluence import is a one-time, one-way process, so edits made in Confluence afterward will not appear in Aha! search.

Editor's takeNow Assist drafts knowledge articles straight from incident records and, since a November 2024 patch, finally indexes modular Knowledge Blocks in AI Search, closing a gap that once made content invisible. The Guardian framework screens for prompt injection and offensive content in real time, and usage grew 9x between January and June 2025. Pricing stays a weak point: consumption-based Assist costs are not detailed on standard order forms, and access requires a Pro Plus or Enterprise Plus add-on.

Could Now Assist search Knowledge Blocks before?

No. Until a November 2024 update (Xanadu Patch 3), AI Search could not index Knowledge Blocks, so content inside them was missed by search and Now Assist.

What does Now Assist Guardian do?

It monitors and blocks offensive content and prompt injection attempts, and redirects sensitive topics like workplace harassment away from generated AI responses.

Editor's takeProProfs wins on simplicity: G2 rates its ease of use at 9.5, well ahead of competitors like Author-It at 7.6, and setup requires no coding. A forever-free plan covers up to 25 articles, and content translates into more than 90 languages out of the box. The pricing catches up on paid tiers though: removing ProProfs branding and using a custom domain costs an extra $300 a year on top of per-author fees that scale linearly.

Is ProProfs Knowledge Base free?

A Forever Free plan covers up to 25 articles. Paid plans start around $49 per author per month billed annually, with a custom domain costing an additional $300 a year.

Questions people ask

How much does Glean cost?

Pricing is not public, but reports cite about $50 a user monthly with a minimum contract around $50,000 to $60,000 a year, according to a third-party pricing analysis.

Does Glean enforce data permissions?

Yes. It strictly inherits permissions from source applications, so users only see search results for content they are already authorized to access, according to Glean's own documentation.

How many documents can Azure AI Search handle?

Up to 24 billion documents per index on standard tiers, with dynamic throttling under heavy load rather than fixed rate limits.

Does Azure AI Search's semantic ranker cover all results?

No. It reranks only the top 50 results from the initial retrieval, which can limit relevance for deep research queries.

Is Coveo HIPAA compliant?

Yes. Coveo holds ISO 27001, ISO 27701, SOC 2 Type II certifications and is HIPAA compliant, with encryption at rest and in transit.

How is Coveo priced?

Pricing is not public. Coveo uses a consumption-based model tied to query volume, which some users say makes costs hard to predict at scale.

Does Guru have a free plan?

Guru offers a free starter option and a 30-day free trial, but paid self-serve plans require a 10-seat minimum, pushing the real cost to about $250 to $300 a month.

Does Guru work inside Slack?

Yes. Guru's Slack integration lets users search, capture and verify knowledge cards directly inside Slack channels, according to a Slack case study on Shopify's use of Guru.

How is the best Knowledge Base Tools with AI Search decided?

Every product is scored on six criteria for this category, with cited evidence and documented penalties. Rank follows the overall score. Vendors cannot pay for a position.

How often is this ranking updated?

Products are re-scored when pricing, features or evidence change. This ranking was last updated July 12, 2026.
