The short answer

Slite is ahead on authoring and search (7.3 vs 5.7), knowledge governance (6.8 vs 3.5) and access control (7.2 vs 6.0), with 6 judges leaning Slite on each, and on publishing and integrations (6.3 vs 5.7; 4 lean Slite, 2 ties). Nuclino leads only on sovereignty, 5.3 vs 3.7 with 6 judges leaning Nuclino — its verdict credits the German entity and a dated subprocessor list with data location Europe, while weighing the privacy policy's transfer reservation and no published data processing agreement. Portability and hosting is close (4.0 vs 3.8; 1 lean Slite, 5 ties) and pricing transparency splits 5 lean Slite, 1 tie. Weighted totals for the six judges run 5.9, 5.5, 6.6, 5.9, 5.9, 5.0 for Slite against 4.9, 4.9, 5.1, 5.2, 4.2, 4.7 for Nuclino. The leans differ by criterion; that split is the answer, not a winner.

Choose Nuclino if

  • You weight vendor sovereignty heavily in a knowledge-base purchase: 6 judges leaned Nuclino on that criterion (5.3 vs 3.7).
  • Your contracts must sit with a German GmbH — Nuclino GmbH of Grünwald, Germany — rather than Slite, Inc., a Delaware corporation.
  • Your vendor review requires a dated subprocessor list with data location recorded as Europe, as Nuclino's verdict documents.
  • Your procurement policy requires a product recorded as EU-made; Nuclino's provenance entry reads EU-made.

Choose Slite if

  • You need documents that stay verified: knowledge governance leans Slite with 6 judges to 0 (6.8 vs 3.5), with documented API-settable verification expiries and an agent that flags outdated docs against Slack, GitHub and Linear activity.
  • Your team writes all day: authoring and search leans Slite 6 judges to 0 (7.3 vs 5.7) on a real-time editor with Markdown, diagrams and hundreds of embeds, plus AI answers citing their exact sources across 20-plus connected sources.
  • You control access per document: access control leans Slite 6 judges to 0 (7.2 vs 6.0), with per-doc roles and cascading permissions that every query inherits.
  • You want published per-user prices: Basic at $10 per user/month and Pro at $20 per user/month, both billed yearly; pricing transparency leans Slite 5 judges to 1 tie (5.2 vs 3.8).
  • You rely on publishing and integrations: that criterion leans Slite 4 judges to 0 with 2 ties (6.3 vs 5.7).

The IT Administrator

Runs IT for a public utility with 900 staff whose Confluence Server held twelve years of pages until Atlassian ended its support. Was offered the cloud, read the subprocessor list and went looking instead. Needs a migration that keeps page trees, permissions and attachments, single sign-on against Entra ID with groups synced, an audit log the auditor accepts, and an edition they can run in the utility's own data centre if the works council or the regulator asks.

This judge's pick

Criterion by criterion

Editor, structure & search

Nuclino

The captured pages show collaborative documents with flowcharts, file embeds and task assignment, workspaces with collections, list/board/table/graph views, real-time co-editing, a large template library, version restore and a documented search section. We found no public information on tables and code blocks in the editor, search filters, attachment search, or AI answers that cite their source pages, so this reaches a solid mid level and no further.

Slite

A real-time collaborative editor with templates, history, comments and mentions, diagrams (Draw.io, Mermaid, Excalidraw, Lucidchart) and Markdown both supported, and embeds for hundreds of tools. AI answers cite their exact sources with a trust signal per citation, search reaches Slack, Google Drive and 20+ connected sources, and every query inherits the user's permissions; we found no public information on backlinks, a link graph, or search across attachments.

Verification, ownership & freshness

Nuclino

The evidence covers version history with restore, an audit log described only as insights into important team events, and team insights naming active contributors and popular content. We found no public information on page owners, review intervals with reminders, approval or publishing workflows, read confirmations or stale-content analytics — nothing here my auditor would treat as a controlled document process.

Slite

Doc ownership and a verification workflow with expiry dates settable through the API, scheduled maintenance checks that run automatically, and an agent that flags stale content by comparing docs against Slack, GitHub and Linear activity and drafts fixes for human triage. Reading and search analytics, version history and full audit logs are stated; we found no public information on read confirmations for mandatory pages, duplicate detection, or whether the audit trail can be exported.

Permissions, SSO & administration

Nuclino

SAML-based single sign-on with ADFS and Microsoft Entra ID, workspace-level roles, access and editing restrictions, private workspaces, guests and read-only members, two-factor authentication, groups, and admin restrictions on public sharing and export are all documented, and the AI connection is stated to see only content the account has access to. We found no public information on directory group sync, SCIM or LDAP provisioning, enforced two-factor authentication or IP restrictions — group sync from Entra ID is exactly what I need for 900 staff, so this stops short of enterprise grade.

Slite

OpenID SSO and SCIM provisioning are on the plan pages, five workspace roles plus doc-level roles with cascading inheritance, guest collaborators, admin control over public sharing and invitations, audit logging of authentication, SSO and admin actions, and AI queries that inherit the user's permissions even for third-party agents. We found no public information on enforced two-factor authentication for users, IP or domain restrictions, or directory group sync beyond the words SCIM provisioning.

Help-center publishing & integrations

Nuclino

Publishing to a website with a custom domain and a documented Markdown API are evidenced, and the MCP server is unusually well described with OAuth 2.0, permission scoping, revocation and named clients including Claude, ChatGPT, Cursor, VS Code and Windsurf. We found no public information on named integrations with Slack, Teams, Jira or Google Drive, webhooks, a help center with SEO controls, or multilingual publishing.

Slite

Public docs with custom domain, branding and SEO indexing, a documented public API with rate-limit responses, Slack and Google Drive among 20+ search sources, a remote MCP server with OAuth and 40+ tools, and a Chrome extension. We found no public information on webhooks, multilingual publishing, a customer-facing widget or logged-in help-center access; Intercom appears as an import source rather than a publishing channel.

Import, export & self-hosting

Nuclino

The help center carries an import and export section, imports from several common formats and tools are mentioned without naming Confluence, and the API can push and pull content as Markdown. We found no public information on a Confluence migration path that keeps hierarchy, permissions and attachments, a full export with attachments and history, or any self-hosted edition — the terms describe a cloud software-as-a-service with all data stored in the cloud — and for twelve years of pages that is the whole question.

Slite

Import from Confluence is named alongside Notion, ClickUp, Quip and OneNote, and the API can fetch a document with its entire subtree in SliteML or HTML, but the captured pages give no detail on whether hierarchy, permissions or attachments survive a Confluence migration. The help pages state that doc history and comments are not included in exports and that exporting several docs in bulk is not possible, and we found no public information on a self-hosted or on-premise edition.

European sovereignty

Nuclino

Nuclino GmbH of Grünwald, registered at the Munich local court and contracting under German law with Munich jurisdiction, publishes a subprocessor list with a change date, naming Amazon Web Services EMEA in Luxembourg and Heroku, a United States company, both with data location Europe. We found no public information on the AI model provider behind Sidekick in the captured subprocessor entries, a published data processing agreement, security certifications, or a statement that customer content is not used for training — the model reading my pages is the first thing the works council and the regulator will ask about.

Slite

The contracting entity is Slite, Inc., a Delaware corporation in San Francisco, with the Paris entity explicitly stated not to commercialise the service or contract with customers; hosting is Google Cloud Platform operated by Google LLC. Media assets and daily backups are stated to sit in EU storage and EU data centres, a data processing addendum with standard contractual clauses and SOC 2 Type II are published, and customer content is stated not to train external models — but the region of the primary database, search index and AI processing is not stated, and subprocessors appear by category with only Stripe named.

Pricing transparency

Nuclino

A free plan, monthly or yearly paid billing, VAT excluded from stated amounts, auto-renewal with a maximum of one year and two weeks' notice, MCP on all plans, and a clear rule that every user including guests and read-only members counts toward the paid team are all public. We found no public information on the per-user price of each tier, which features such as single sign-on or the audit log sit in which plan, storage limits or minimum seats, so I cannot compute an annual cost for 900 staff from these pages.

Slite

Basic at "$10 per user/month Billed yearly" and Pro at "$20 per user/month Billed yearly" are public with storage per user, AI limits and inclusions listed, which lets me compute two-thirds of the bill. The Enterprise tier, where reader-only seats, SCIM, audit logs and migration support sit, is custom pricing on contact, and readers are Enterprise-only; we found no public information on minimum seats, term or VAT treatment.
