Create Bots without programming using AI.

Encode expert knowledge using our DARL language, and trigger expert system based conversations with your customers, collecting data and ensuring compliance.


Create Bots that function with the Microsoft™ Azure Bot System, and that connect to Skype, FaceBook Messenger and more.

No Programming

No C# or Javascript; no compilation. Specify the text responded to as word or concept sequences.

NLP based

Uses a language model to make it simple to write matches with a wide range of user phrases, to extract data and to trigger text responses or expert systems.

Fuzzy logic expert system

You can encode knowledge, like how to comply with a set of regulations, and trigger a conversation eliciting the required data from the user.
