Comparison
Multibase vs HelpDocs
HelpDocs and Multibase both publish customer-facing knowledge bases with AI answers. The difference is structure: HelpDocs gives each account one knowledge base and keeps its attribution on every plan, while Multibase runs several separately branded portals from one account, from $49/mo.
For one knowledge base Multibase Growth costs $49/mo versus $99/mo for HelpDocs Sprout (both billed annually); for 3 separate knowledge bases it is $49 versus about $257, because HelpDocs needs one account per knowledge base. HelpDocs keeps its attribution on every plan; Multibase removes branding from Growth.

Where Multibase wins
Real multi-brand in one account
Each Multibase portal has its own articles, domain and branding. On HelpDocs, extra domains reuse the same content, and a separate knowledge base needs a separate account and plan.
No required attribution
Branding removal is included from Growth. HelpDocs attribution is required on every plan.
Lower entry, and a free plan
Growth is $49/mo for 3 portals versus $99/mo for one HelpDocs knowledge base (both billed annually). Starter is free; HelpDocs has a trial only.
Public MCP for readers' AI tools
Every portal has a public, read-only MCP endpoint that any compatible AI assistant can query. HelpDocs MCP is authenticated and meant for authors and admins.
Where HelpDocs wins
Deeper AI authoring
AI drafts, rewrites, AI meta, alt text and tags from Sprout, plus AI improve and style enforcement on Bloom. Multibase offers AI article generation and AI translation, but less writing tooling.
Author-side MCP that can write
HelpDocs MCP lets authors create, update and delete articles and categories, and read analytics, from an AI assistant. Multibase MCP is read-only and serves published public content.
Mature in-app widget
Lighthouse embeds help inside your product with a JS API and live-chat handoff. HelpDocs also tracks AI crawls and most-cited articles.
More editors per plan
Sprout includes 5 editors and Bloom 15, against 3 admins on Multibase Growth and 10 on Scale.
The verdict
Choose Multibase if you run two or more brands, need separate content per brand or want no vendor attribution: 3 portals cost $49/mo versus about $257/mo for three HelpDocs accounts. Choose HelpDocs if you have a single brand and value deep AI authoring, a writable author-side MCP or the Lighthouse in-app widget.
Frequently asked questions
Not in one account. HelpDocs plans include one knowledge base, and each extra one is a separate account on its own plan, with 20% off the cheapest plan when billed together. Additional domains change the logo, colors, name and SEO but show the same articles. On Multibase Growth, 3 portals with separate content cost $49/mo.
No. HelpDocs attribution is required on every plan: you can show it as text, a logo or both, and some plans offer a cobranded option, but you cannot turn it off. Multibase removes its branding from Growth at $49/mo; only the free Starter plan shows a "Powered by Multibase" footer.
Both answer reader questions with AI: HelpDocs Sprout includes 1,000 AI credits/mo and Multibase Growth 1,000 AI queries/mo, with source citations on every Multibase answer. HelpDocs Sprout supports 3 languages and 10 machine translations a month; Multibase supports 9 content languages and includes AI translation on every plan from the AI allowance.
HelpDocs is the better choice for a single brand with a larger writing team: Sprout includes 5 editors versus 3 admins on Multibase Growth. It also wins on AI authoring (drafts, rewrites, style enforcement on Bloom), the Lighthouse in-app widget with live-chat handoff, and an author-side MCP that can create and edit articles. Multibase's MCP endpoint is public and read-only.
