Consumers appreciate interesting and entertaining applications. Our team has invented a new conversational content development approach, allowing our team of linguists and writers to create and test exciting and engaging content fast.

Our set of unique authoring tools and runtime components takes advantage of various NLP technologies, suggesting alternatives, summarizing content, scraping the internet, accessing knowledge databases etc. We also rely on sub-dialogues serving as templates for frequently repeating conversational situations. All these techniques and tools are helping us to make the development and operation process of conversational apps effective and fast. We have embedded all of this stuff into our unique conversational platform available as a cloud service.

Visual designer

Dialogue models are designed by our unique visual design tool offering basic conversation building blocks as well as complex reusable sub-dialogues plus embedded web client allowing to immediately test and debug any dialogue step by step with all available settings on behalf of any user. The tool also supports the use of audiovisual content to enrich bot responses with pictures, music, snippets or even videos and animations to bring voice-driven communication to the next level.

Dialogue scripting

Our dialogue model can be extended using DSL scripting language we call DialogueScript, embedding various conversation decision making algorithms while utilizing all known user context data, including mentioned entities and other data identified in previous reactions as well as information stored in long-term user context (“bot’s memory”) which can be combined with entities from connected knowledge databases.

Conversation analytics

When it comes to designing entertaining applications, it is necessary to be able to analyse every human interaction in detail. Therefore, we have strong support for both implicit and customizable metrics covering different parts of the dialogues and visualising them runtime. These metrics can help us change application settings and modify the conversation design to improve user experience and results.

Common distribution system

The platform contains a distribution system capable of targeting conversational apps created or consumed by different organizations to specific user groups or even individuals with custom settings. This distribution system separates content from the specifics of any specific platform like Google Assistant or Alexa.

Multi-channel experience

Promethist can provide conversational experience via many different channels capable of conversational interaction such as web, Intelligent Voice Assistant (IVA) platforms (Alexa, Google Assistant), mobile and wearable platforms (Apple, Google Android) and even custom device types.
