Which one is for you
Pick Chatbase if
- Fits if you want an AI agent on your site trained on your own help docs
- Works for teams already on Zendesk or Intercom that want AI in front of it, from Standard at $120
Look elsewhere if
- Pricey if a team of people answers too, as 5 members means Pro at $400 a month
- Too light for a real help desk on the $32 plan, which is the bot alone with no API
- Skip it if you hate branding on the widget, since removing it costs $1,188 a year
- Watch out: extra message credits are $40 per 1,000, and each extra AI agent is $300 a year
- Not for you if you want a free plan, as there's only a 7-day trial and no ticketing or help center on record
Pick Heroic Knowledge Base if
- Fits if you already run a WordPress site and want a knowledge base
- Works for a site that wants a plugin rather than a hosted service
Look elsewhere if
- Not for you if you do not use WordPress, as there is no hosted version
- Tight if you want analytics or private articles, because those need Plus at $349
- Pricey if you renew, since the 50% first-year price only applies once
- Watch out: each site is one license, and each multisite sub-site counts separately

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
