As of 1 Nov 2026, the panel rates Confluence 3/5 and Notion Wikis 3/5 in Knowledge Base & Wiki. Weighted by what each judge cares about, 2 of the 6 judges pick Confluence and 4 pick Notion Wikis. Confluence scores higher on 4 of 7 criteria (Editor, structure & search, European sovereignty, Help-center publishing & integrations, plus 1 more). Notion Wikis scores higher on 3 of 7 criteria (Verification, ownership & freshness, Permissions, SSO & administration and Pricing transparency). Provenance — Confluence: Rest of world; Notion Wikis: Rest of world, United States. Ratings are the AI panel’s opinion, formed from public evidence: how scores are made.
Confluence and Notion Wikis split this panel. Confluence's means run higher on authoring and search (7.2 vs 6.7; three judges lean Confluence, none Notion Wikis), publishing and integrations (6.8 vs 6.5), portability and hosting (6.2 vs 6.0) and sovereignty (5.2 vs 4.8, leaning Confluence 3-2). Notion Wikis' means run higher on knowledge governance (6.0 vs 4.7; four judges lean Notion Wikis, none Confluence), access control (7.7 vs 7.2) and pricing transparency (6.0 vs 5.7). The governance gap traces to a genuine split on Confluence: four judges scored 4, declining to count the approval workflow they found in developer documentation last updated in 2018; two scored 6. Weighted totals divide 4-2 — Notion Wikis ahead for the operations lead, IT administrator, engineering lead and skeptic; Confluence for the support knowledge manager and quality manager. Notion Wikis' legal entity jurisdiction is listed as US; Confluence's sovereignty attributes are listed as unknown.
Choose Confluence if
You need live co-editing and full-text search that reaches attached files, Google Drive and SharePoint — authoring and search leans Confluence three judges to none (means 7.2 vs 6.7).
Your wiki content has to flow out to other tools — publishing and integrations leans Confluence two judges to none, with four ties (6.8 vs 6.5).
You want a self-managed edition on the table — portability and hosting leans Confluence one judge to none with five ties, and the verdict records the self-managed Data Center edition, whose life ends March 28, 2029.
A US contracting entity is a blocker for you — Notion Wikis' legal entity jurisdiction is listed as US, and the sovereignty criterion leans Confluence three judges to two (5.2 vs 4.8).
Your buyer group looks like the support knowledge manager or the quality manager — their weighted totals favor Confluence, 6.2 vs 6.1 and 6.5 vs 6.1.
Choose Notion Wikis if
You need knowledge governance you can show auditors — knowledge governance leans Notion Wikis four judges to none (6.0 vs 4.7), while four Confluence judges declined to count its approval-workflow evidence, found in developer documentation last updated in 2018.
Your team must enforce single sign-on exclusively and provision accounts automatically — Notion Wikis documents SAML 2.0 with any identity provider, Only SAML SSO login enforcement and SCIM provisioning; access control leans its way three judges to none (7.7 vs 7.2).
Your compliance stack needs the wiki audit log piped onward — Notion Wikis documents an audit log that can feed a SIEM or DLP, part of the access-control criterion it leads three judges to none.
Comparing published prices is your gating step — pricing transparency leans Notion Wikis two judges to none, with four ties (6.0 vs 5.7).
Your buyer group mirrors the IT administrator or engineering lead — weighted totals put Notion Wikis ahead for both, 6.6 vs 5.9 and 6.6 vs 6.2.
Read this comparison as one judge. Each weighs the same scores by what they care about.
The Support Knowledge Manager
Owns the knowledge base of a Dutch SaaS company with customers in six languages and a support team of twenty-five. Writes once for agents and customers, publishes the public part as a help center on the company's own domain, and watches which searches find nothing. Wants review dates that nag the right expert, translations kept in step with the source, a widget inside the product, and articles that show up in the help desk next to the ticket.
Confluence
This judge's pick
Notion Wikis
Criterion by criterion
Editor, structure & search
Confluence
Spaces with a nested content tree, templates, macros and embeds, live co-editing with comments and tagging, page versioning with revert, and search with suggestions across pages and attached Office and PDF files are all documented, and search reaches into Google Drive and SharePoint with related pages and whiteboards for diagramming. It sits just under the top band because wiki markup is confined to the legacy editor and the captured pages do not show AI answers citing the pages they draw on.
Notion Wikis
The captured pages show a page-and-database editor with teamspaces and subpage trees, @ mentions linking pages, synced blocks, a 30,000+ template gallery and filtered search, plus AI search that matches meaning across vague titles and Enterprise Search reaching into Slack, Google Drive and GitHub. What holds it short of the top anchors: we found no public information on backlinks or a link graph, attachment search, or AI answers that cite their source pages — and for my multilingual help center, no linked translations of a page are documented either.
Verification, ownership & freshness
Confluence
Live docs act as drafts convertible to published pages, publishing can be scheduled, page history compares and reverts, Premium adds analytics, the site audit log exports to CSV, and a documented author-and-approver workflow blocks self-approval and rolls back to the last accepted version. We found no public information on per-page owners, review dates with reminders, read confirmations, or reporting on searches that return nothing — the gaps a support team feels daily.
Notion Wikis
This earns its keep for a support team: pages can be marked verified for a set period, and when verification lapses the page owner is nudged in the Notion inbox and by email, with verified pages surfacing higher in search and AI answers. Page analytics show total and unique views plus who created, edited or viewed a page, Enterprise adds admin content analytics and an audit log that can feed a SIEM, and a published article advises mining query data for high-volume searches with no satisfying result. We found no public information on approval workflows with reviewers or read confirmations for mandatory pages, and duplicate or stale content handling appears as advice rather than an automated feature.
Permissions, SSO & administration
Confluence
Granular space and page permissions, guests confined to one space at up to five per paid user, SAML single sign-on with enforced two-step verification and automated provisioning via Atlassian Guard, IP allowlisting, multiple identity providers, and an audit log that exports and can be forwarded by webhook put this at the enterprise band. The guest permission model is published with its limits in real detail; we found no public information on whether search and AI answers honour page permissions.
Notion Wikis
The permission model is documented down to six levels from full access to can view, with teamspace and page-level rights, subpage inheritance, guests who need their own Notion account, link expiry and a request-access flow — and the quirks are published too, such as guests being excluded from SAML login. SAML 2.0 single sign-on with any identity provider (Business and up, up to 25 configurations on Enterprise), Just-in-Time provisioning, SCIM user and group provisioning, admin roles and an audit log exportable to SIEM or DLP are all evidenced. We found no public information on IP or domain restrictions, and enforcing two-factor authentication across the workspace is not documented as an explicit admin policy.
Help-center publishing & integrations
Confluence
Anonymous and public spaces publish support documentation to anyone on the internet, articles can be multilingual, Jira Service Management connects the knowledge base to centralised self-service support, and the REST API v2 with a downloadable OpenAPI spec, webhooks, an apps marketplace and an MCP server endpoint for Rovo are all documented. We found no public information on a custom domain, SEO controls, or a widget embedded in our own product — exactly the surfaces a help center is published on.
Notion Wikis
Publishing to the web is real: any page becomes a Notion Site with a custom domain add-on, branding and logo removal, editable SEO title and description, search-engine indexing, Google Analytics and embeds of published pages into other sites — behind it sit webhooks, a documented API with a JavaScript SDK, a marketplace and an MCP server for AI assistants. But the help-center gaps matter for my use case: the captured pages state password protection is not available at the moment, and we found no public information on multilingual publishing, an in-product help widget, or help-desk ticket deflection — Jira and Slack are present as integrations, not as a deflection flow.
Import, export & self-hosting
Confluence
The free Cloud Migration Assistant moves space data, users, attachments and Marketplace apps from Server or Data Center with pre- and post-migration reports, the REST API covers pages and attachments, and the data processing addendum requires deletion of customer personal data after termination. The self-managed Data Center edition carries a published end of life in March 2029, and we found no public information on a full export in an open format with page history.
Notion Wikis
Arriving is well served: a documented Confluence importer covering cloud and server instances that keeps hierarchy, attachments and comments (permissions explicitly must be reapplied), plus Word, Markdown, CSV, Evernote, Trello and ZIP imports with published size limits. Leaving is honest but not painless — a full workspace export to Markdown, HTML and CSV with uploaded files, even schedulable via the admin API on Enterprise, though the documentation says a workspace cannot be recreated by re-uploading an export, comments only export in HTML, and we found no public information on page history in exports. We found no public information on a self-hosted or on-premise edition.
European sovereignty
Confluence
The contracting entity is Atlassian Pty Ltd under Australian law with an EU representative in Atlassian B.V., the data processing addendum publishes SCCs governed by Irish law, and a sub-processor list names locations including the AI providers. Residency is an opt-in feature covering only certain in-scope data while the default footprint spans the EEA, UK, USA and beyond, with OpenAI, Mailchimp, Snowflake and Zendesk located in the USA; we found no public information on ISO 27001 or SOC 2 certification, and the captured pages do not state that customer content is kept out of AI model training.
Notion Wikis
The chain is unusually transparent: a published subprocessor list with locations including the AI providers (OpenAI, Anthropic and Google all marked Global), a data processing agreement covering EU and UK GDPR, repeated commitments that customer data is never used for training, and SOC 2 Type 2 plus ISO 27001 and its siblings. But the contracting entity is Notion Labs, Inc. of San Francisco, data sits in the United States by default, and EU residency is an Enterprise-only opt-in on AWS Frankfurt or Ireland that excludes account information, usage data, Calendar, Mail and anything processed by subprocessors including the LLM providers — so even a resident workspace's AI features run outside the region.
Pricing transparency
Confluence
Free, Standard at $5.78 per user / month and Premium at $11.16 per user / month are published with storage tiers, automation steps, Rovo credits, user limits and free guests at up to five per paid user, with annual billing saving up to 17 percent. Enterprise is sales-only, the Atlassian Guard subscriptions that carry single sign-on are unpriced on these pages, and we found no public information on the self-managed edition's licence cost, minimum seats or term, or VAT treatment.
Notion Wikis
The pricing page is granular: Free at €0, Plus at €9.50 per member / month, Business at €19.50 with SAML SSO included, guests free but limited to pages they are invited to (ten on the free tier), per-member AI credits with overage at $10 per 1,000 monthly Notion credits, and a custom domain add-on at an additional $10 per month or $8 per month on annual billing, per domain. What stops me computing a real annual cost: Enterprise — where SCIM, the audit log, EU data residency (free of charge there) and premium support live — is Custom pricing, and we found no public information on minimum seats, minimum term or VAT treatment.
