Cognigy.AI Docs

COGNIGY.AI is the Conversational AI Platform focused on the needs of large enterprises to develop, deploy and run Conversational AI’s on any conversational channel.

Given the arising need of voice interfaces as the most natural way of communicating with brands, Cognigy was founded in 2016 by Sascha Poggemann and Phil Heltewig. Our mission: to enable all devices and applications to intelligently communicate with their users via naturally spoken or written dialogue.

Released: December 23rd, 2020


Cognigy Live Agent (lite)

Cognigy Live Agent (lite) is here! The Cognigy Live Agent replaces the old Cognigy Livechat in Cognigy.AI version 4. Live Agent comes as a more de-coupled product and will be extended in the future.

Quick NLU training

We have introduced a quicker way for you to train your Intents. If users do not utilize states and conditions in their Intents, they can now use the new quick training method in order to train their Intents way faster. Users can still decide whether they want to go with the slower training approach which will take states and conditions into consideration.

Indian languages

These release of Cognigy.AI introduces support for the following new languages:

  • Hindi
  • Bengali
  • Tamil

We are always happy to extend the capabilities of our product and would love to get feedback on the quality of the language support for these new languages.

WebchatWidget WCAG 2.0 Level A Compliance

We added full support for WCAG 2.0 Level A Compliance to our WebchatWidget. Release 2.24.0 of our WebchatWidget offers accessibility features we did not support, yet. We have also added the ability to specify the necessary alternative text for all sorts of rich-media elements our users can compose in the 'default' and 'webchat' Channels within our Say-Node editor.

Please have a look at our release-page on GitHub:
