Slite

What Is Slite?

Every growing team hits the same wall. Documents accumulate. Knowledge scatters across Notion pages, Confluence wikis, shared drives, and someone's email thread from 2023. When a new hire asks where to find the onboarding checklist, the answer is a slack message, a search that returns 40 results, and a fifteen-minute detour. Slite was built to solve exactly this.

Founded in Paris in 2017, Slite is a French knowledge base designed around one core belief: the value of documentation is in retrieving it, not writing it. The company's engineering has focused heavily on the retrieval side — specifically, on AI-powered answers that surface the right information without requiring the user to know where to look.

Slite SAS operates as a French company under full EU jurisdiction. Data is hosted in European data centres. The AI does not train on customer content. For EU-based teams navigating GDPR requirements, those are structural guarantees, not optional settings.

The product competes directly with Notion and Confluence in the team knowledge base category. Its positioning is deliberate: Slite is not trying to be the most flexible tool. It is trying to be the most useful one for teams whose primary use case is writing, sharing, and finding internal documentation.

Key Features

AI Ask — Answers, Not Search Results

Ask is Slite's headline feature and its most meaningful point of differentiation. Rather than returning a list of documents that might contain the answer, Ask reads the question, searches the knowledge base, and returns a direct answer — with citations to the source documents.

The distinction matters more than it sounds. Traditional search tools return links. Ask returns answers. A team member asking "what is our refund policy for enterprise customers?" gets the relevant policy text, not a list of five documents that each mention the word "refund". The cited sources let teams verify the answer and access the full document in one click.

Unlimited Ask access requires the Knowledge Suite plan at $25/user/month (or $16 billed annually). The Standard plan includes a restricted version. This gating creates a meaningful push toward the higher tier for teams that use Ask heavily — which is most teams after they try it.

Knowledge Verification Workflow

Documentation goes stale. Slite's verification system addresses this directly with a freshness tracking mechanism: document owners get prompted to confirm whether content is still accurate. Outdated documents get flagged, keeping the knowledge base's signal-to-noise ratio high over time.

This is a feature most knowledge base tools ignore. Confluence and Notion surface content based on search relevance, with no systematic way to identify what is outdated. Slite's approach shifts the maintenance burden from reactive (realising content is wrong after it causes a problem) to proactive.

Editor and Collaboration

The editing experience is intentionally restrained. Slite does not support relational databases, complex views, or formula-driven properties — that's Notion's territory. The editor focuses on what documentation actually needs: rich text, embeds, tables, code blocks, and real-time co-editing. Pages nest into collections with a clean sidebar hierarchy.

Version history tracks changes at the document level. Role-based access controls let admins set workspace-level and collection-level permissions. Private workspaces allow teams to draft content before publishing to the broader organisation.

Security and Compliance Infrastructure

Slite holds SOC 2 Type II certification — an audited standard that verifies security controls meet a defined benchmark. GDPR compliance is built in as a function of French HQ rather than bolted on as an afterthought. HIPAA compliance is available for Enterprise customers, making Slite viable for healthcare-adjacent teams handling sensitive data.

The AI's data boundary is explicit: Slite does not use customer content to train its models. For teams working with proprietary or sensitive information, that contractual separation matters.

Pricing

Slite's pricing is per user per month, with linear scaling — a structure that rewards smaller teams and penalises large ones. The free plan supports up to 3 members with unlimited documents and basic search. It covers solo founders and very small teams evaluating the product without commitment.

The Standard plan runs $10/user/month ($8 billed annually). It unlocks unlimited members, Slack and Google Drive integrations, and limited Ask access. This is the appropriate entry point for most growing teams.

The Knowledge Suite at $25/user/month ($16 annually) is Slite's premium tier, targeting organisations that depend on AI-powered search and need advanced analytics and priority support. The jump from Standard is significant — nearly three times the annual per-user cost. Teams should assess how heavily they will use AI Ask before committing to Knowledge Suite for everyone.

Enterprise pricing is custom and adds HIPAA compliance, SSO, SCIM provisioning, and dedicated customer success. Large organisations with compliance requirements or complex identity management needs should request an Enterprise quote.

For teams of 10–25 on the Standard plan, the annual cost lands around $960–$2,400 per year — competitive with Confluence's pricing at equivalent team size, and substantially cheaper than Notion for equivalent knowledge-base functionality.

EU Compliance & Privacy

Slite's compliance posture is one of the strongest in the knowledge base category. As a French SAS (Société par Actions Simplifiée), the company is incorporated and regulated in an EU member state. GDPR applies by default — there is no need to execute a separate Data Processing Agreement for basic compliance, though one is available for Enterprise.

Data is hosted in EU data centres. The AI search system does not train on customer content. SOC 2 Type II certification provides external audit verification of security controls — not just a self-attestation. HIPAA availability on Enterprise opens the door for US-adjacent health organisations operating under transatlantic data requirements.

For EU organisations comparing Slite against Notion (US-headquartered) or Confluence (Atlassian, Australian-headquartered with US cloud infrastructure), the jurisdictional difference is material. Slite's data never leaves EU infrastructure unless explicitly configured otherwise.

Who It's Best For

Product and engineering teams that generate documentation at speed — RFCs, runbooks, API docs, postmortems — and need a search layer that returns answers rather than results. The knowledge verification workflow keeps frequently updated technical docs fresh.

Operations and HR teams maintaining policy documentation, onboarding materials, and process guides. AI Ask handles the "what is the policy on X" questions that otherwise land in someone's Slack DMs.

EU-regulated organisations in finance, healthcare, or government where data residency and GDPR compliance are procurement requirements, not preferences. Slite's EU jurisdiction and SOC 2 certification satisfy most compliance checklists.

Teams switching from Confluence who find Atlassian's complexity and pricing frustrating. Slite supports Confluence imports and offers a meaningfully simpler editing experience.

The Verdict

Slite solves a real problem with a genuinely useful feature in AI Ask. The knowledge verification workflow is an underrated differentiator. The EU-native compliance position makes procurement straightforward for regulated organisations. The trade-off is real: Slite cannot replace Notion for database-heavy workflows, and the Knowledge Suite pricing is a significant jump from Standard. Teams that write a lot and search even more will find Slite earns its cost. Teams that need relational databases alongside their docs should look elsewhere.

Frequently Asked Questions

Is Slite GDPR compliant?

Yes. Slite is a French company (Slite SAS) incorporated in an EU member state and subject to GDPR by default. Data is hosted in EU data centres, and Slite holds SOC 2 Type II certification. The AI does not train on customer content.

How does Slite's AI Ask feature work?

Ask indexes your entire knowledge base and responds to natural language questions with direct answers, citing the source documents. It is not a standard search engine — it reads the question and synthesises an answer from your docs rather than returning a list of links.

How does Slite compare to Notion?

Slite is purpose-built for documentation and knowledge retrieval. Notion is more flexible — it supports databases, project management, and custom views. Slite is simpler to use for pure knowledge-base workflows and offers tighter AI integration. Teams that need relational databases alongside their docs are better served by Notion.

Does Slite have a free plan?

Yes. The free plan supports up to 3 members with unlimited documents and basic search. The Standard plan starts at $8/user/month billed annually for unlimited members.

Where is Slite data hosted?

Slite hosts all data in EU data centres. As a French-incorporated company, it falls fully under EU jurisdiction and GDPR regulation.
