Echo Knowledge Base – Documentation, FAQs, Chat & Smart Search

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. The recent download trend is too spiky to read.

   Hello I have been using Echo for a few days and have now become familiar with all the features. In addition, I bought the add-ons. The AI feature is brilliant by the way! I’m totally thrilled. The support is also unbeatable. The people at Echo are very helpful, friendly and respond quickly. I am totally happy that I found Echo through the google search. I hope you continue to develop the project. Thank you for your great work. Stephanie

   We are using the plugin within our organization to build and maintain our internal knowledge base – and we are absolutely impressed. The setup process is quick and straightforward, allowing you to get started with minimal effort. One of the biggest advantages is the ease of use in day-to-day work: creating, organizing, and maintaining content is simple and intuitive, even for users without a strong technical background. The feature set of the free version is already very powerful and provides everything needed for a professional knowledge base. The premium versions offer even more flexibility and advanced features, making the system highly scalable.
