Slite vs Slab: which modern wiki should you use in 2026?

Last updated May 2026

You're leaving Confluence. You've narrowed it to two modern alternatives that both promise what Confluence doesn't: a clean interface, fast search, and a wiki your team might actually use.

Slite has AI. Ask a question, get an answer from your docs with citations. Channels for async team updates alongside documentation. Verification workflows to catch stale content.

Slab has the best editor. Fast, polished, focused. The search works well across posts and integrated apps. No AI, but the writing and reading experience is the cleanest in the category.

Same price range. Same target audience. Different bets on what makes a wiki work.

Side-by-side comparison

Where Slite wins

AI. This is the biggest difference. Slite's "Ask" feature lets anyone ask a question in natural language and get an answer cited from your team's documentation. Slab has no AI. In 2026, that gap is hard to ignore. If a new hire needs to find the PTO policy, Slite's AI surfaces the answer with a source link. In Slab, they search by keyword and hope the right post comes up.

Verification. Document owners receive reminders to review and verify their content on a schedule. Stale docs get flagged. This doesn't eliminate the maintenance problem, but it makes staleness visible rather than invisible. Slab has no verification. A page from 2023 looks identical to a page updated yesterday.

Channels. Async update channels alongside documentation. Team announcements, decisions, weekly updates. Slite isn't just a wiki. It's a wiki plus a lightweight communication layer. Slab is purely documentation.

Enterprise search. On Knowledge Suite ($20/user/month), Slite searches across Slack, Jira, and Google Drive alongside your docs. Slab's unified search covers integrated apps but at a shallower level.

Mobile apps. Native iOS and Android. Slab has no native mobile apps.

Where Slab wins

The editor. Slab's writing experience is the best in the wiki category. Fast, polished, focused. Users praise it consistently across review platforms. Slite's editor is good. Slab's is better. If your team writes a lot and the writing experience matters, Slab makes documentation feel less like a chore.

Search speed. Slab's full-text search across posts and integrated apps is fast and reliable. Users praise it specifically. Slite's AI-powered search is more capable in theory but Slab's keyword search is more predictably fast in practice.

Price. Slab Startup at $6.67/user/month versus Slite Standard at $8/user/month. Free tier: Slab gives unlimited posts for 10 users. Slite gives 50 docs with limited AI. For budget-conscious teams, Slab's free tier is more usable for real work.

Confluence migration. Slab has a dedicated Confluence importer. The migration path is direct. Slite requires manual migration from Confluence.

Simpler model. Slab is documentation. Nothing else. No channels, no verification workflows, no enterprise search tiers. The product does one thing and does it cleanly. If you just want a wiki, Slab doesn't add complexity you don't need.

Where both fall short

Both are wikis. Both require someone to write pages, maintain structure, and keep content current. Slite's verification helps catch staleness. Slab's editor makes writing pleasant. Neither eliminates the fundamental requirement: human discipline.

Neither handles diverse content. PDFs, meeting recordings, images, design files, video references. Both treat them as attachments or embeds, not as content the AI reads, indexes, and searches inside. Your team's knowledge probably lives in more than wiki pages.

Neither has deep semantic search. Slite's AI Q&A works on documented content. Slab's search is keyword-based. Neither searches by meaning across all content types, inside PDFs by paragraph, or inside video by transcript.

Neither has a workspace beyond the wiki. No spatial canvas. No meeting transcription. No task management. No publishing with analytics. After the wiki page is written, everything else happens in other tools.

Neither has SOC 2. For teams with compliance requirements, both fall short.

If neither wiki is enough

Both Slite and Slab are good wikis. If your team will maintain a wiki, either works. The choice comes down to AI Q&A (Slite) versus editor quality (Slab).

But if your team's knowledge extends beyond wiki pages, or if wiki maintenance is the part that's failed before, neither tool addresses the underlying problem.

Fabric does. You save content, any file type, from any source. The AI organises and connects it automatically. Semantic search finds things by meaning: inside PDFs, inside recordings, across images, by colour palette. No wiki to maintain. No pages to write. No verification reminders to ignore.

Notes with real-time co-editing. A spatial canvas with live embeds. Annotations on any content. Bot-free meeting transcription. Tasks with due dates. Publishing with analytics. The wiki that doesn't need building.

$5/month flat. No per-user pricing. A 20-person team on Slite Standard pays $160/month. On Slab Startup, $133/month. On Fabric, $5/month.
