About HelpCenter.io

HelpCenter.io is a hosted knowledge base platform for building a branded, searchable help center on your own domain, with an embeddable AI widget, reusable FAQ sections, and AI answers grounded only in your published articles. It deliberately skips ticketing and CRM and charges a flat price per help center instead of per agent. Every public help center also exposes an MCP server and llms.txt so assistants like ChatGPT and Claude can read and cite your articles.

Pros & Cons

Pros

Flat price per help center with unlimited viewers, so cost doesn't scale with support headcount
AI answers are grounded only in your published articles and link back to the source article
Built-in public MCP server and llms.txt make help content readable by ChatGPT and Claude on every plan
Custom domain with SSL included even on the entry plan
Reviewers consistently praise ease of use and responsive, hands-on support
Integrates with Intercom, Zendesk, HubSpot, and Front for agents who share articles

Cons

No ticketing, live chat, or CRM, so you need a separate help desk
Bootstrap allows only 1 team member and 1 language
AI question answering is a $29/mo add-on below the Catalyst plan
SSO and automatic translations are limited to the $179+/mo Catalyst plan
Small vendor with a limited review base (around a dozen reviews on Capterra/Software Advice)

Key Features

Template editor

Start from one of 15 help center templates and restyle colors, fonts, sections, and layout in a live drag-and-drop editor with desktop, tablet, and mobile previews.

AI widget

One script adds a launcher with search, articles, and answers inside your product or website, suggesting articles that fit the page the customer is on.

Ask AI answers

Instant search plus an Ask AI button that streams answers composed only from your published articles, each linked to its source, with thumbs up/down ratings logged to analytics.

Reusable FAQ sections

Write FAQs once and display them on pricing, checkout, signup, and partner pages; editing an answer updates every page that shows it.

MCP server and llms.txt

Each public help center has its own /mcp endpoint and serves articles as clean Markdown with an llms.txt index, so AI assistants can search and cite your content. Team-side MCP access lets Claude or ChatGPT find content gaps and draft articles for review.

Custom domain and subfolder hosting

Serve the help center at help.yourcompany.com with free SSL on every plan, or at yourcompany.com/docs via a proxy rule on Growth and Catalyst.

Multi-language publishing

Publish articles in multiple languages with a reader language menu, plus one-pass AI translation of the whole knowledge base on Catalyst.

Editorial workflow

Drafts, version history with restore, scheduled review reminders, staged multi-article releases, and roles for admins, editors, translators, and viewers.
