Slab is a knowledge base and team wiki that keeps company documentation in one clean, searchable place. This review covers what Slab does well, what each plan really costs, what its AI features include, what users complain about, and how it compares with Notion, Confluence, Guru, Slite, and Tettra.

Most teams don’t have a documentation problem. They have a finding problem. The onboarding guide lives in Google Drive, the deploy steps are in a Slack thread from last March, and the pricing policy is in someone’s head. New hires ask the same five questions every week because nobody can find the answer.
Slab was built for exactly this. It’s a wiki that tries to stay simple on purpose: write a post, put it in a topic, and let search find it later, even if the answer actually lives in another tool. Below we look at whether that simplicity is a strength or a limit for your team.
Quick answer
Slab is a good fit for startups and mid-size teams that want a clean, fast internal wiki without the setup of Confluence or the blank-canvas sprawl of Notion. It’s free for up to 10 users, paid plans start at $6.67 per user per month (billed annually), and its search can look inside connected tools like Slack, Google Drive, and GitHub. It’s not the right pick if you need heavy formatting, complex tables, databases, or a public help center for customers.

Where the information comes from
- Plans, limits and prices come from Slab’s own pricing page, checked on November 9, 2026. Slab shows annual prices on that page. If you pay monthly, expect to pay more.
- Features, integrations, and security come from Slab’s website, its integrations page, its security page, and its help center.
- User opinion comes from G2, Capterra, and Software Advice. We read the reviews, grouped the common praise and complaints, and quote a few reviewers directly. A lot of Slab’s reviews were collected with a small gift card or were invited by the vendor, which tends to push scores up, so we say where that matters.
- Competitor prices come from each vendor’s own pricing page on the same date.
- No star score of our own. We don’t give Slab a score out of 5. The verdict at the end is editorial judgment by Nitin Kumar, based on the sources listed at the bottom of this page.
Slab’s whole pitch is “a knowledge base, pure and simple.” It doesn’t try to be a project manager, a database, or a docs-plus-everything workspace. If your team keeps abandoning wikis because they get messy, that focus is the reason to look at Slab.
02What is Slab?
Slab is a cloud knowledge base and wiki for internal teams. You write posts (pages), group them into topics, and anyone in the company can search across everything. Its homepage sums up the goal as helping teams “create, organize, and discover knowledge for your entire organization, from non-technical to tech-savvy.”
Companies named on Slab’s website include Asana, Ramp, Fivetran, Benchling, Glossier, Vox Media, Fly.io, Render and A24 Films. That mix says a lot: Slab is popular with tech companies and fast-growing startups, especially those where engineers and non-engineers share the same docs.
Typical things teams keep in Slab:
- Onboarding guides and employee handbooks
- Engineering docs, runbooks and architecture notes
- Sales playbooks, support macros and process docs
- Meeting notes, project briefs and decision logs
What Slab is not: it isn’t a public help center for your customers (tools like Document360 or KnowledgeOwl do that better), and it isn’t an all-in-one workspace with databases and task boards like Notion.
03Key features of Slab
A clean, distraction-free editor
Writing in Slab feels close to writing in a good notes app. You get headings, lists, code blocks, embeds, mentions and real-time collaboration, with Markdown shortcuts for people who like them. There are templates for common docs, so new pages start with a structure instead of a blank screen.
The flip side is that formatting is limited on purpose. Several reviewers mention that complex tables and image handling are weaker than in Notion or Confluence. For most text-heavy docs, this doesn’t matter. For a page full of comparison tables, it can.
Topics instead of folders
Slab’s homepage says “folders and tags are not enough,” and organizes content into topics. A post can sit in more than one topic, so the “Deploy checklist” can live under both Engineering and Onboarding without copies going out of sync. Topics can be nested, pinned, and on paid plans, made private. The Content Map gives a visual overview of how everything is organized.
Unified Search
This is the feature people mention most. Slab’s search returns results from Slab itself and from connected tools, so a search for “refund policy” can show the Slab post, the Google Doc and the Slack message side by side. Reviewers on Capterra and Software Advice regularly call the search fast and accurate.
Verification
Docs go stale. Slab lets you mark a post as verified, so readers can tell at a glance whether a page is current or might be outdated. It’s a small feature, but it solves the biggest trust problem with any wiki. It’s included on every plan, even Free.
Integrations
Slab’s integrations page lists 50 tools. The featured ones are Slack, Google Workspace, and GitHub. Others include Jira, Linear, Asana, Figma, Miro, Loom, Airtable, Dropbox, Box, Trello, Monday, Zendesk and Freshdesk. Some, such as Microsoft, Okta, OneLogin, and Zendesk, are “premium” integrations, which only paid Business and Enterprise plans include.
Easy migration
Slab’s help center has import guides for Confluence, Notion, Google Drive, Guru, Slite, GitBook, Dropbox Paper, and Markdown, HTML, and DOCX files. Its homepage also says, “Switching? We’ll take care of that for you.” If you’re moving off an old wiki, ask for that help during the trial.
Usage analytics
Admins can see which posts get read and which get ignored. The history window depends on the plan: 30 days on Free, 90 days on Startup, 365 days on Business, and unlimited on Enterprise.
04Slab AI features
Slab has added AI features, but they are spread across plans, so it helps to know which one you’re paying for.
| Feature | What it does | Plans |
|---|---|---|
| AI Predict | Suggests the next word as you type, based on the context of your post. Press Tab or the right arrow to accept | Startup, Business, Enterprise |
| AI Autofix | Listed on the pricing page as a writing helper. Slab’s help center doesn’t describe it in detail, so test it in your trial | Startup, Business, Enterprise |
| AI Ask | Listed as a Business plan feature for asking questions of your knowledge base. Enterprise gets an “Advanced” version | Business, Enterprise (Advanced) |
Sources: Slab pricing and Slab help: AI Predict, checked November 9, 2026.
Slab’s AI is useful, but it isn’t the headline. The homepage doesn’t even mention AI, and the question-answering feature is held back for Business. If AI answers over your docs are your top priority, also try Guru or Slite, which build their pitch around it.
05Slab pricing
Slab is refreshingly open about pricing compared with many B2B tools. All prices below are per user per month, billed annually, as shown on Slab’s pricing page. Every plan has unlimited posts and topics.
| Plan | Price | Users and guests | What you get |
|---|---|---|---|
| Free | $0 | Up to 10 users | Real-time editing, templates, verification, unified search, basic SSO, 10 standard integrations, 90-day version history |
| Startup | $6.67 | Unlimited users, 3 guests per user | Private topics, AI Autofix and Predict, unlimited standard integrations, 365-day version history |
| Business | $12.50 | Unlimited users, 5 guests per user | AI Ask, SAML SSO, SCIM provisioning, custom domains, 3 premium integrations, GraphQL API, webhooks, uptime SLA, priority support |
| Enterprise | Custom | At least 100 users, unlimited guests | Advanced AI Ask, audit logs, unlimited premium integrations, dedicated support |
Source: slab.com/pricing, checked November 9, 2026. Prices can change, so confirm before you buy.
What it costs in real life
For a 25-person team on the Startup plan, that’s about $167 a month, or roughly $2,000 a year. The same team on Business pays about $313 a month, or $3,750 a year. Slab bills for each user who can log in, so guests are a cheap way to give contractors access.
Good to know before you pay
- The Free plan is real. It’s “free forever” for up to 10 users with no credit card, which is enough for a small team to run on properly.
- SAML SSO and SCIM need Business. If your IT team insists on Okta-based login and automatic user provisioning, budget for Business, not Startup.
- Audit logs are Enterprise only. Regulated companies should factor that in early.
- There’s a 30-day money-back guarantee. Slab says, “No questions asked.”
- Non-profits and schools can get the Startup plan free through Slab’s discount page.
06Security and admin controls
Your wiki holds a lot of sensitive internal information, so security deserves a look before you move in. Here is what Slab publishes.
| Area | What Slab publishes |
|---|---|
| Certifications | SOC 2 Type 2 and SOC 3 (the SOC 3 report is downloadable). GDPR compliant |
| Hosting | Google Cloud Platform, with daily backups and 24/7 monitoring |
| Encryption | Data in transit over SSL (rated A+ by Qualys SSL Labs). Data at rest encrypted with AES 128/256. Passwords hashed with bcrypt |
| Testing | Annual penetration tests by independent firms, plus automated vulnerability scanning |
| Login | Admins can require SSO and two-factor authentication. SAML SSO and SCIM on Business and above |
| Audit logs | Enterprise plan only |
Sources: Slab security and Slab pricing. Slab’s security page doesn’t list an ISO 27001 certification for Slab itself, so ask if your company requires one.
07What users say about Slab
Slab has more user reviews than most niche wiki tools, and they’re mostly positive. Here’s the summary.
| Source | Rating | Reviews | Notes |
|---|---|---|---|
| G2 | 4.6 / 5 | 309 | Many recent reviews were collected with a small gift card |
| Capterra | 4.9 / 5 | 41 | Ease of use 4.9, customer service 4.9. Many reviews date from 2019 |
| Software Advice | 4.9 / 5 | 41 | Ease of use 4.9, support 4.9, value 4.9, functionality 4.4 |
Sources: G2, Capterra and Software Advice, as shown November 9, 2026. Ratings change over time.
What people like
- It’s easy. Ease of use is the top theme on G2 by a wide margin. Reviewers say the interface is clean and simple to teach to new hires.
- Search works. Fast, accurate search, including results from connected tools, comes up again and again.
- Slack, GitHub, and Google Drive integrations. These are the ones reviewers mention by name.
- Support is responsive. Customer service scores 4.9 on both Capterra and Software Advice.
What people complain about
- Formatting limits. A senior software engineer on G2 wrote that Slab is “based on Markdown, and there are several limitations to it, such as advanced image handling and complex table support.”
- A clunky editor at times. One small-business reviewer on Software Advice said, “The word editing for Slab pages is a bit clunky, but not game-breaking.”
- Overwhelming as content grows. A higher-education user said, “As a new user, it can seem a bit overwhelming at first.”
- Permissions. Some teams find user groups and topic permissions limited or confusing.
- Integration gaps. A few reviewers wanted better GitLab support, PDF handling, or on-premises tools.
Our reading: the praise is consistent and believable, because it matches what Slab is designed to do. The complaints are also consistent, and they’re the cost of a deliberately simple tool. If your team needs a lot of layout control, take those complaints seriously.

09Slab vs alternatives
Slab competes with two kinds of tools: all-in-one workspaces like Notion, and Confluence, and dedicated knowledge bases like Guru, Slite, and Tettra. Here is how they line up on price.
| Tool | Free option | Lowest paid plan | Best for |
|---|---|---|---|
| Slab | Free plan, up to 10 users | $6.67 per user/month, billed annually | Simple internal wiki with strong search |
| Notion | Free plan | Plus $10 per member/month (up to 20% off yearly) | Docs plus databases, tasks, and projects in one place |
| Confluence | Free plan for small teams | See Atlassian’s pricing page | Teams already deep in Jira, and Atlassian |
| Guru | Not stated | Custom quote, no per-seat price published | Knowledge served inside Slack, browser, and support tools |
| Slite | 14-day free trial | Basic $10 per user/month, billed yearly | AI-first knowledge base with Q&A answers |
| Tettra | 30-day free trial | Scaling $8 per user/month, 10-user minimum | Small teams that want Q&A in Slack |
Sources: each vendor’s pricing page (Notion, Confluence, Guru, Slite, Tettra), checked November 9, 2026.
Slab vs Notion
Notion can do much more: databases, project boards, wikis and personal notes all in one tool. That flexibility is also its weak spot as a company wiki, because pages multiply, and structure falls apart unless someone owns it. Slab does one job, and keeps it tidy. If you want a wiki people can find things in, Slab is easier to keep clean. If you want one tool for docs and projects, pick Notion. Read our full Notion review.
Slab vs Confluence
Confluence is the default for companies that live in Jira, and it has deeper page layouts, macros, and permissions. It also has a reputation for being heavy, and slow to navigate. Slab is lighter, and quicker to learn, and it can import your Confluence spaces if you decide to switch. See our Confluence review.
Slab vs Guru
Guru is built to push verified answers into the tools where people already work, like Slack and the browser, and it’s popular with sales and support teams. It doesn’t publish per-seat pricing and now sells custom packages. Slab is the cheaper, more document-centered option. Our Guru review goes deeper.
Slab vs Slite and Tettra
Slite leans hard into AI answers and is the closest like-for-like rival, but starts at $10 per user and has no permanent free plan. Tettra is a lightweight, Slack-centered option for small teams; see our Tettra review. For a broader view, our Bloomfire review covers a tool aimed at larger companies.
10Who should use Slab?
A strong fit. The free plan covers up to 10 people, and Startup is one of the cheapest paid wikis around.
A good fit. GitHub, Linear and Jira integrations, code blocks and Markdown make it comfortable for developers.
Worth a look. Topics, verification and import tools are made for cleaning up old documentation.
Fine on Business or Enterprise. Budget for Business if you need SAML SSO and SCIM, and Enterprise for audit logs.
Probably not. Slab has no databases or task boards, so Notion or ClickUp would suit you better.
Not the right tool. Use a public knowledge base like Document360 or Help Scout instead.
11FAQs
What is Slab used for?
Slab is used as an internal knowledge base and team wiki. Companies keep onboarding guides, handbooks, engineering docs, processes and meeting notes in it, and use its search to find answers across Slab and connected tools like Slack and Google Drive.
Is Slab free?
Yes. Slab has a free-forever plan for up to 10 users with unlimited posts, templates, verification and unified search. No credit card is needed. Larger teams need a paid plan.
How much does Slab cost?
Slab’s Startup plan is $6.67 per user per month and Business is $12.50 per user per month, both billed annually. Enterprise pricing is custom and needs at least 100 users. Slab offers a 30-day money-back guarantee.
Does Slab have AI?
Yes. AI Predict and AI Autofix help you write and are on Startup and above. AI Ask, for asking questions of your knowledge base, is on Business, with an Advanced version on Enterprise.
Is Slab secure?
Slab says it holds SOC 2 Type 2 and SOC 3, is GDPR compliant, runs on Google Cloud, encrypts data in transit and at rest, and runs annual penetration tests. SAML SSO and SCIM are on Business and above, and audit logs are on Enterprise.
Is Slab better than Notion?
For a company wiki, Slab is simpler and easier to keep organized. Notion is more flexible and adds databases and project tools. Choose Slab for focused documentation and Notion if you want docs and work management in one place.
Can I move from Confluence or Notion to Slab?
Yes. Slab has import guides for Confluence, Notion, Google Drive, Guru, Slite, GitBook and Dropbox Paper, plus Markdown, HTML and Docx files. Slab also says it will help you switch.
Does Slab integrate with Slack?
Yes. Slack is one of Slab’s featured integrations, along with Google Workspace and GitHub. Slab lists 50 integrations in total.
12Final verdict: is Slab worth it?
For teams that want a wiki people will actually use, Slab is worth trying. It’s easy to learn, its search is genuinely helpful, the free plan is usable, and the Startup plan is cheap compared with Notion, Slite or Confluence. User feedback backs this up, even after you allow for incentivized reviews.
The limits are real too. Formatting is basic, there are no databases, and the most useful AI feature and the stronger security controls sit on the Business plan. Teams that need rich layouts or an all-in-one workspace will feel boxed in.
The sensible next step is to put one real team on the free plan for two weeks. Move your onboarding docs in, connect Slack and Google Drive, and see whether people stop asking the same questions. That will tell you more than any feature list.
