HelpCenter.io
A sensible pick for teams that want a self-service knowledge base without paying per support seat, and the MCP servers make it one of the few help centers an AI assistant can actually edit with review. The useful AI pieces sit on Growth and above, so the $29 Bootstrap tier is a plain single-author knowledge base.
Pros
- Flat price per help center, with up to 10 teammates on Growth
- Uses the platform's own search analytics to show which articles readers could not find
- A read-only MCP server comes with every public help center at no extra charge
- 365-day analytics retention, translations and AI answers on the top plan
Cons
- Bootstrap is limited to a single team member and 14 days of analytics
- AI question answering is an add-on below Catalyst
- Editing through ChatGPT needs developer mode and a qualifying ChatGPT plan billed separately
