Why Slab is not a customer help center
Slab is a solid internal wiki for teams. But when your customers need answers, they need something built for them: public pages, search-engine visibility, and AI that cites your articles.
Slab is internal by design
Slab is built for team collaboration: private docs, internal search, Slack integration. It does not generate public URLs, sitemap files, or structured data. Your customers cannot find your articles on Google, and neither can ChatGPT.
No AI assistant for customers
Slab has internal search for your team. Helpable has Calli, a conversational AI that answers customer questions using your articles and provides source links. Calli works in the widget, on your help center, and escalates to your inbox when it cannot help.
No embeddable widget
You cannot embed Slab in your product. Helpable gives you a floating widget with one script tag. Customers search and ask questions without leaving the page they are on.
Per-user pricing adds up fast
Slab Startup is $6.67/user/month and Business is $12.50/user/month. A 20-person team on Business pays $250/month for an internal wiki. Helpable Pro is $79/month for unlimited team members, with a customer-facing help center included.

When Slab is the right choice
If your goal is purely internal knowledge sharing, onboarding docs, and team wikis with Slack integration, Slab is a clean, well-designed tool for that job. It is not trying to be a customer help center, and it does that internal role well.
When Helpable is the right choice
If you need a customer-facing knowledge base that ranks on Google, answers questions with AI, and lives inside your product as a widget, Helpable is built for that from the ground up. You can use both: Slab for your team, Helpable for your customers.
Slab pricing vs Helpable: what you actually pay.
Slab is free for up to 10 users. Startup is $6.67/user/month, Business is $12.50/user/month. A 20-person team on Business pays $250/month for internal docs. Helpable Starter is $29/month (1 user, 2,500 AI answers). Pro is $79/month with unlimited team members and 10,000 AI answers. The key difference: Slab is an internal wiki. Helpable is a customer-facing help center with AI, SEO, and a widget.

“We had Slab for the team and nothing for customers. We set up Helpable in a morning and cut incoming support emails by 35% in the first month.”
Tom H., Head of Product, Datawell (Data SaaS, 18-person team)
“Slab is great for our internal docs, but our customers could not access any of it. Helpable gave us a proper help center on our own domain with AI search built in.”
