Strengths & Weaknesses
Deep Dive
Slab wins on raw per-seat cost—$6.67/user/month (annual) is the cheapest paid tier in the internal wiki market. However, that low price reflects a stripped-down feature set with no AI, no API, and no custom branding. Tettra's $4/user Basic plan includes Kai AI and content verification, making it arguably better value despite the lower sticker price. For teams that need AI-assisted knowledge management, Tettra's $4/user delivers more functional value than Slab's $6.67/user. Both tools are genuinely affordable compared to Confluence or Notion, but you get exactly what you pay for—minimal feature sets with no external delivery capability.
Both tools use per-user pricing, which means costs scale linearly with headcount and can become expensive at larger team sizes. Slab's Business tier has no published pricing, creating uncertainty for growing teams. A 50-person team on Slab Startup pays $333/month; Tettra Scaling costs $400/month for the same size. Tettra's Professional tier at $12/user becomes $600/month for 50 users—still reasonable by enterprise standards. The real scalability concern is feature ceiling: neither tool adds meaningful capability as you spend more, and both hit a wall when teams need external delivery, multi-tenant portals, or advanced compliance features that no tier provides.
The biggest hidden cost with both Slab and Tettra is what they don't do—forcing supplemental tool purchases. No video-to-documentation capability means separate screen recording tools. No multi-tenant portals means separate customer documentation platforms. No multi-language support means separate translation services. No LMS means a separate training platform. Slab's hidden cost is its feature ceiling—teams eventually outgrow it and migrate, incurring switching costs. Tettra's hidden cost is the SSO gap: jumping from $8/user Scaling to $12/user Professional solely for SAML represents a 50% price increase just for an authentication feature. Neither tool offers a free trial-to-paid migration without credit card commitment at the same time.
Side-by-Side Pricing
Every pricing tier for Slab and Tettra laid out side by side—so you can see exactly what each dollar buys you.
Tettra offers better pricing transparency and more value per dollar at its entry tier ($4/user with AI included), while Slab wins on simplicity with only two paid tiers. However, both tools share the same fundamental ceiling—neither supports external documentation delivery, multi-tenant portals, video-to-docs conversion, or multi-language support at any price point. Teams that start with either tool often find themselves purchasing supplemental platforms as their documentation needs mature, negating the initial cost savings.
Our Recommendation
Slab and Tettra are both legitimately affordable internal wiki tools, but they serve slightly different needs. Slab is the simpler, cheaper option for teams that want a no-frills internal knowledge base with minimal setup. Tettra adds AI-powered Q&A via Slack integration and a cleaner tier structure, making it a better value for teams already deep in the Slack ecosystem—especially when AI assistance matters.

Winner: Docsie
Both Slab and Tettra are limited to internal-only documentation with no external delivery capability, no video processing, no multi-language support, and no LMS—regardless of which pricing tier you choose. Docsie's workspace-based pricing model ($199/month for 15 users) eliminates per-seat inflation, and its six-pillar platform covers the full CONVERT → MANAGE → DELIVER → LEARN → AUTOMATE → MONITOR workflow that both Slab and Tettra cannot address even at their highest price points.
Common Questions
Q: Which is cheaper—Slab or Tettra?
A: It depends on team size and needs. Tettra's Basic plan at $4/user/month is cheaper than Slab's Startup plan at $6.67/user/month, and Tettra includes AI features at that lower price. However, Slab's free plan is more capable (real-time collaboration, 90-day history) than Tettra's for teams under 10 users. For most paid use cases, Tettra delivers more features per dollar.
Q: Does Slab offer a free trial?
A: No. Slab does not offer a free trial on its paid Startup plan—it only offers a free plan capped at 10 users. You would need to commit to a paid subscription to access features like unlimited version history and advanced analytics. Tettra, by contrast, offers a 30-day free trial on its paid plans, which is a meaningful advantage when evaluating the two tools.
Q: What do you get for Tettra's $12/user Professional plan that isn't in Scaling?
A: Tettra's Professional plan at $12/user adds three things over the $8/user Scaling tier: SSO/SAML for enterprise authentication, custom branding for your knowledge base, and a dedicated customer success manager. If your team doesn't need SSO or branded portals, the Scaling plan at $8/user covers most practical needs including API access and analytics.
Q: Is Slab's Business plan worth the custom pricing?
A: Slab's Business plan adds SSO, advanced security, and dedicated support—features that competitors like Tettra include in defined paid tiers without requiring a sales call. If those features are essential, you'd likely get more transparent pricing and comparable enterprise features from Tettra's Professional plan at $12/user before reaching out to Slab's sales team.
Q: Is there a better alternative to both Slab and Tettra for teams that need more than an internal wiki?
A: Yes—Docsie addresses the core limitations shared by both tools. Neither Slab nor Tettra can convert videos into documentation, deliver content to external clients through branded portals, support 100+ languages, or provide built-in LMS and certification capabilities. Docsie's Premium plan at $199/month for 15 users includes all of these features, plus AI credits for video processing, SOC 2 Type II compliance, and multi-tenant portal delivery—making it the stronger choice for teams whose documentation needs extend beyond internal knowledge sharing.
Q: Can Slab or Tettra scale to serve external customers or multiple clients?
A: No. Both Slab and Tettra are internal-only tools with no external documentation delivery at any price point. Neither supports custom domains, white-labeled customer portals, or multi-tenant architectures. If your team needs to deliver documentation to customers, partners, or multiple client organizations, you would need to purchase a separate documentation platform on top of either tool—negating much of the cost savings from their affordable pricing.
Docsie goes beyond internal wikis—convert any training video into searchable documentation, deliver it through branded multi-tenant portals, support 100+ languages, and train teams with built-in LMS and certifications. All at flat workspace pricing that doesn't inflate with every new team member you add.
Free plan includes AI credits to convert a 10-minute training video. No credit card required.
