Project Settings
The configuration menu that provides customization options to activate, deactivate, and adjust important settings that affect the performance and results of the project's NLU and Flow logic. For more information, read the Project Settings article.


The process of charging customers for the usage of Cognigy products. In the context of Cognigy, billing is related to the charges users incur for their interactions with the Cognigy platform. In Cognigy's billing model, the fundamental unit of consumption is a conversation. A conversation is an interaction between a user and a virtual or human agent within the Cognigy platform. Each conversation is considered a billable unit, and customers are charged based on the number of conversations they have. For more information, read the Billing documentation.
A Bot (short for "robot") is a software application that performs automated tasks typically associated with human interaction. Bots are programmed to execute specific functions autonomously, often without direct human intervention. However, at Cognigy, we prefer the term "virtual agent" instead of "bot" to refer to our automated solutions, such as AI Agents. For more information, read the virtual agent documentation.


A unit of knowledge that is extracted from a Knowledge Source. Chunks are small, self-contained units of information that the Knowledge AI system searches through and accesses in order to answer user questions. For more information, read the Knowledge AI documentation.
Chunk Editor
A tool that helps you interact with and manage Chunks. The Editor provides a user-friendly interface that enables you to manipulate the content within each chunk. Users can modify the text, add new information, delete sections, or rearrange the order of content to ensure the accuracy and relevance of the knowledge. For more information, read the Knowledge AI documentation.

When a contact disconnects from Cognigy.AI, the Context is persisted in the database and retrieved upon reconnection. For more information, read the Context documentation.
A billable unit of interaction between a user and a virtual agent or human agent. For more information about billed conversations, read the Billing documentation.
Conversational AI
A technology that enables computers to interact with humans in natural language. It includes chatbots, virtual assistants, and other interfaces that understand and respond to user queries. This technology uses AI and natural language processing to simulate humanlike conversations and is used in various industries for tasks like customer service and information retrieval.


A connector within Cognigy.AI that enables seamless interaction between Cognigy virtual agents and external systems or platforms. It acts as a bridge, facilitating bidirectional communication, and allows virtual agents to send and receive messages to and from external services. Each Cognigy Endpoint represents a specific communication channel or interface through which the virtual agent can connect and engage with users or other systems. For example, if you want your virtual agent to be available on both Webchat and Facebook Messenger, you would create two Cognigy Endpoints: one for Webchat and another for Facebook Messenger. These Endpoints would handle incoming and outgoing messages for their respective platforms, enabling the virtual agent to provide responses and receive user inputs on both channels. For more information, read the Endpoints documentation.
Custom-built JavaScript modules that extend the platform's capabilities beyond its core features. With extensions, users can create custom actions, conditions, and integrations to enhance the virtual agent's responses and interactions. These custom functionalities can range from performing complex calculations, accessing external data, making API calls, integrating with databases, and more. For more information, read the Marketplace Extensions documentation.


A visual representation of a potential dialog using a Flow chart. Flows are composed of individual Nodes with different functionalities, ranging from generating output to collecting back-end information. When an input comes in through an Endpoint, the Flow is executed, enabling smooth interactions with users. For more information, read the Flows documentation.
Flow Editor
A graphical interface where users can create and organize the dialogue paths and define the interaction logic by using Nodes. Users can drag and drop Nodes representing different actions, conditions, prompts, and responses to design a Flow.

Generative AI
A type of artificial intelligence that creates new content, such as images, video, audio, and text, using machine learning algorithms. It works by learning from existing data and producing new content based on that learning. Cognigy.AI integrates with multiple generative AI providers and their LLMs to empower you to improve real-time customer interactions through personalized responses, advanced language understanding and sentiment analysis. For more information, read the Generative AI documentation and see Wikipedia.

Input (Object)
A short-term JSON data object generated each time a message is sent to Cognigy.AI. The Input Object contains general information about the message, such as the time it was received and the channel from which it was sent. It also includes specific results from the NLU intent mapping process, such as the selected Intent, identified Slots, and other useful information. The Input Object is passed to the Flow to determine the next action. You can find more information about the input's lifespan on the CognigyScript page. For more information, read the Input documentation.
