A simple yet feature-packed builder to create AI-powered solutions

Just AI Conversational Platform

A full-range and secure conversational AI platform for solutions of any complexity. Keep everything under control with key statistics and customized reports

Just AI Conversational Framework

An open-source Kotlin-based conversational framework that is free of charge even for commercial use


CAILA is built into Just AI products. No need to integrate with a third-party NLU service or search for libraries:

  • Qualitative text processing: recognition of synonyms, acronyms, and slang expressions
  • Increased accuracy of intent recognition, faster processing of unlabeled logs and data selection to train AI systems
  • New NLP models and algorithms powered by machine learning, rule-based approach, semantic and morphological analysis
  • Provided access to Just AI’s proprietary language technologies and linguistic libraries containing source code

How does CAILA work

Someone is asking a chatbot to make a call

CAILA defines the subject of inquiry and all the characteristics mentioned by the person.
