Our customers are our biggest fans. Here's just some of the amazing feedback we've received:

At Pagely we set up Heroic KB as a pre-sales knowledge base for people evaluating our managed WordPress hosting service.

Heroic KB has been a great asset to the Pagely sales process. The search feature provides a fast way to filter by keyword and the categorical organization gives a simple means to browse by topic. Analytics show us which articles are unclear and need refinement. Having it indexed by Google gives us SEO benefits.

We're happy customers of HeroThemes and endorse both the product and the support we've received from the company.

Heroic KB was an elegant solution to update our Knowledge Base with its minimalist eye-catching design. Everyone on the team, from the developer to the marketing lead, were able to navigate their way easily through the dashboard editor. Even though we were under a time crunch, we were able to get it set up quickly and in time for Mailbutler's big launch.

Highly recommend HeroThemes for your Knowledge Base needs!

Tobias Knobl Tobias Knobl CEO - Mailbutler

Having tried a few free plugins and third party systems but not found one that meets my needs. The Heroic KB plugin was much better than anything else I had tried and really easy to set up.

It's great that you can structure the articles into multiple levels of sub-categories. The instant search is excellent. I love the fact that the knowledge base part of my main website which helps with SEO. The analytics facility is great and provides concrete ideas on how I can improve the knowledge base to help clients and reduce the number of support tickets.

My technical director found it easy to hook into the templates and style the knowledge base to look really professional. Thanks very much!
