Patent drawing from the official filing.

This filing describes a system that turns documents into interactive chat cards to help users learn. It uses machine learning to score how well a user understands a topic and then changes the next question or prompt based on that score.

Why it mattersIt could make online learning or training tools more personalized by adjusting difficulty in real-time based on your answers.

In the filing’s own words

Systems and methods for providing adaptive and conversational chat cards are provided herein. For example, a method may include receiving, from a client device, an indication to start a chat card exercise, determining, by a chat card engine, a source document based on the chat card exercise, and generating chat cards based on the source document. Each of the chat cards may correspond to a subtopic present in the source document. As such, the chat card engine may generate a first prompt based on a first subtopic and provide the first prompt within a first chat card to the client device. The chat card engine may receive a first query from the client device responsive to the first prompt and determine an understanding score. The chat card engine may then generate a second prompt based on the understanding score and provide the second prompt in the first chat card.

What exactly they claim (claim 1)

1. A system comprising: one or more computer readable storage media; one or more processors operatively coupled with the one or more computer readable storage media; and an application comprising program instructions stored on the one or more computer readable storage media that, when executed by the one or more processors, direct a computing system to at least: receive input content associated with a subject matter; generate, by a chat card engine comprising a machine learning model, a chat card comprising a prompt configured to elicit a response from a user based on the subject matter; provide, via a user interface, the chat card to a client device; receive, via the user interface, a user response associated with the chat card; determine, by the chat card engine using the machine learning model, an understanding score representing a level of user understanding based on (i) the user response and (ii) interaction data associated with the user; generate, by the chat card engine, an updated chat card based on the understanding score and the interaction data; adapt interaction with the user by modifying content of the updated chat card based on the understanding score; and provide, via the user interface, the updated chat card to the client device to continue an interactive session.
