What is Slab?

Slab is a knowledge management platform built for teams that need a single, trustworthy home for internal documentation, processes, and institutional knowledge. Instead of scattering how-tos across Slack threads, Google Docs, and someone’s memory, Slab gives you a structured wiki with a distraction-free editor, hierarchical Topics for organization, and a content verification system that flags when a post has gone stale. The whole product is optimized around one problem: making sure the right information is easy to find and easy to trust.

The company, Slab, Inc., has been building the product since the late 2010s and positions it squarely against Confluence, Notion, and Guru. Its customer roster leans toward tech and mid-market teams — Asana, Benchling, Fivetran, and Ashby are among the logos on its site. Slab’s pitch is that it does one thing (a company wiki) really well rather than trying to be an all-in-one workspace, and that focus shows in how clean and fast the app feels compared to bloatier competitors.

What Are Slab’s Key Features?

Fast, collaborative editor

Slab’s editor is one of its strongest selling points. It supports real-time collaboration so multiple people can edit a post at once without clobbering each other, and it handles rich media, tables, interactive widgets, and third-party embeds. It feels closer to a modern document editor than a clunky legacy wiki, and it’s noticeably quicker than Confluence.

Unified search across your tools

Search is the feature Slab is proudest of, and it earns it. Results appear as you type and are ranked by relevance signals like reads, views, links, and mentions. More importantly, unified search indexes content from integrated tools — so a query can surface answers living in Google Drive, Slack, or GitHub, not just inside Slab itself. That turns Slab into a front door for company knowledge rather than yet another silo.

Verification and content health

Every wiki eventually rots. Slab tackles this with a verification system: designated owners mark posts as verified, and the app tracks when content is due for review. Admin analytics dashboards surface which posts are helpful, which are stale, and which team questions are going unanswered, so knowledge maintenance becomes a deliberate workflow instead of an afterthought.

Topics, integrations, and AI

Slab organizes content into Topics that support multiple labels and a hierarchy, so a single post can live in more than one logical place. It integrates with dozens of apps including Google Workspace, Slack, GitHub, Asana, and Okta. Paid tiers add AI features — AI Autofix on Startup, and AI Predict plus AI Ask on Business — layering answer generation and content suggestions on top of the wiki.

How Much Does Slab Cost?

Slab starts free for up to 10 users, then moves to the Startup plan at $6.67 per user per month (billed annually) for unlimited users, with the Business plan at $12.50 per user per month adding SSO, SCIM, custom domains, unlimited version history, and the fuller AI suite. Enterprise is custom-quoted and requires at least 100 users. That pricing lands it below Confluence’s premium tiers and roughly in line with Notion’s Business plan, though Notion bundles far more general-purpose functionality for a similar per-seat cost. Where Slab wins on value is that you’re paying for a focused, polished wiki rather than a sprawling toolkit you’ll only half-use.

Who Is Slab Best For?

Slab is a great fit for growing companies — roughly 20 to a few hundred people — that have outgrown ad-hoc docs and want a clean, maintainable internal wiki without the enterprise weight of Confluence.

Use Slab if you want a fast editor, strong search that reaches into your other tools, and a real system for keeping docs verified and current. It’s ideal if a tidy, single-purpose knowledge base matters more to you than an all-in-one workspace.

Skip Slab if you’re a tiny solo team that just needs a few docs (Notion’s free tier is enough), or if you want your wiki to double as a project tracker, database, and CRM — Slab deliberately doesn’t do those things.

Best Slab Alternatives

Slab competes in a crowded knowledge-management space. Here are the three alternatives worth weighing against it.

Notion

Notion is the all-in-one workspace that also does wikis, databases, and project management. Its Business plan runs around $15/user/mo, similar to Slab’s Business tier, but it’s far more flexible — and far more prone to becoming a disorganized mess. Choose Notion for versatility, Slab for a focused, faster, easier-to-maintain wiki.

Confluence

Atlassian’s Confluence is the enterprise incumbent, starting around $5.16/user/mo and integrating tightly with Jira. It’s powerful and deeply extensible but feels dated and heavy next to Slab. Pick Confluence if you’re already all-in on the Atlassian stack; pick Slab if you want something modern that your team will actually enjoy using.

Guru

Guru focuses on knowledge that lives where you work — surfacing verified answers inside Slack and your browser — and leans harder into AI-powered enterprise search. It’s typically pricier per seat. Guru is the better fit if you want knowledge pushed into workflows; Slab is better as a central, structured wiki you browse and edit.

Final Verdict: Is Slab Worth It?

Slab is one of the most pleasant team wikis on the market. The editor is fast, the search genuinely reaches beyond the app into your other tools, and the verification system solves the single biggest problem every knowledge base eventually hits — content going stale without anyone noticing. For a growing company that wants documentation to actually get used, that focus is worth a lot.

The catch is scope. Slab does wikis and only wikis, so if you’re hoping one tool can also run your projects and databases, Notion or ClickUp will serve you better. And at $12.50/user/mo for Business-tier essentials like SSO, costs add up as you scale. But if a clean, trustworthy, searchable knowledge base is the job, Slab does it better than most — recommended for mid-sized teams that value clarity over kitchen-sink flexibility.
