Frequently Asked Questions

OpenDialog is a conversational experience platform. It introduces a unique approach to conversation design and development enabling teams to design, develop, deploy, test and maintain sophisticated conversational applications that can use a number of different conversational interfaces (web, SMS, Slack, WhatApp, etc), NLP interpreters and integrate with your own systems and services.

OpenDialog is not just another tool for conversation design and development. It allows you to design and deploy sophisticated conversational applications faster because it starts from a strong foundational conversational model and method of reasoning.

Our approach is based on AI research on how we communicate, cooperate and coordinate in environments with multiple participants.

We provide an intuitive builder to enable you to design using this approach and a smart and proactive conversation engine to run the resulting applications. We make no limiting assumption about what sorts of interpreters are possible and provide a consistent and coherent way to manage context and action throughout an interaction.

Yes, we offer OpenDialog Enterprise edition with multiple environments,  full access to codebase, customised SSO Integrations – See the description above. This can be either self-hosted or hosted on our cloud. Get in touch for pricing.

Yes! OpenDialog is also available as an open-source tool – get all the details on Github.

OpenDialog is open-source and the OpenDialog team is on hand to provide assistance. Our no-code conversation platform was designed specifically to enable you to get up and running quickly, designing and deploying your own conversations with ease. 

OpenDialog can be used as a stand-alone solution to run conversational application or it can be integrated with other NLU tools, interfaces, and services. 

Conversation volume cost (excl. VAT)

Pricing for conversations kicks in when a conversational application is launched (i.e for WebChat that is when the widget is placed on another domain) and we charge a conversation / fixed monthly cost:

  • 0 – 1,000 conversations – £50 (min. fee)
  • 1,001 – 20,000 conversations – £0.03 per conversation
  • >20,001 conversations – £0.02 per conversation

A conversation consists of the exchange of up to 60 messages (i.e. 30 conversational turns). 

A conversation is counted only when a user interacts with the conversational application and the application successfully responds – not when the application sends a welcome message. 

While OpenDialog is in launch beta (ending early 2022) all interactions for the cloud edition are free! 


Seat charge (excl. VAT)

For personal use or for training/learning purposes, OpenDialog is free of charge. With the free account you can design, prototype, explore for personal use.

For business use, whether prototyping applications to share more widely with stakeholders or for launching applications you will be charged a fixed monthly cost of £30 per seat / per month for your workspace.


While OpenDialog is in launch beta (ending early 2022) all seat charges for the cloud edition are free!  

All Prices exc. VAT. For more information about our pricing structure please read our pricing policy
