Conversational AI

Building valuable interactions with conversational applications


Get in touch to understand how conversational applications can transform the way your team, and your customers, work.

Conversational applications are built using a set of emerging technologies. These include both conversational AI and/or UX principles, which can engineer human-like conversations between people and computers. These conversations can take the form of chatbots, voicebots, virtual agents or smart speaker-enabled digital assistants.

If your organisation is yet to explore the full potential of such technology, now is the time to assess what it could do for you and your employees. It’s clear that those who have invested in it are already reaping the benefits. In 2020, between February and April alone, IBM noted a 40% rise in traffic through its Watson Assistant. The advent of digitalisation, particularly during the COVID-19 pandemic, means reviewing virtual, technology-based alternatives now is vital.

  • Supports French, German, and English by using Microsoft LUIS to identify intent and entity.
  • Improved customer experience.
  • Audit processing time has decreased thanks to AI classification and recommendation.

“I approached the team with a complex problem. I needed a chatbot which could navigate the complex world of cyber-crime so we could help victims contain threats. The creativity and expertise they applied to the project helped us build a unique capability.”

Rory Innes, CEO, The Cyber Helpline
