  • Patent number: 12647532
    Abstract: Systems and methods for generating online meeting summaries for videoconferencing are provided. For example, a computing device establishes a video conference for a plurality of participants. While the video conference is in progress, the computing device receives a first portion of a transcript of the video conference and generates a first meeting summary based on the first portion of the transcript. The computing device causes the first meeting summary to be presented in a user interface accessible by a client computing device associated with at least one of the plurality of participants. The computing device receives a second portion of the transcript of the video conference and generates a second meeting summary based on the first portion and the second portion of the transcript. The computing device causes the second meeting summary to be presented in the user interface.

  • Patent number: 12641047
    Abstract: Example methods and systems recommend and summarize unread messages for a user on an online chat platform. A client device accesses multiple unread messages associated with the user, and a machine learning (ML) model provided by the online chat platform. The client device selects one or more unread messages from the multiple unread messages using the ML model trained with historical chat data and user metadata. The client device also generates a summary of some or all of the unread messages using a second ML model trained with the historical chat data and the user metadata. The indication of the selected unread messages and the summary of unread messages are displayed on the client device.

  • Patent number: 12634162
    Abstract: Some examples involve an artificial intelligence (AI) system for handling a query about a conversation, such as a conversation between attendees of a videoconferencing meeting. As one example, the system can receive a query from a user about a conversation between attendees of a videoconferencing meeting. The system can determine a relevant portion of the conversation based on the query, determine an intent of the query by providing the query as input to an intent detection model, and select a machine-learning model from among a group of machine-learning models based on the intent of the query. The system can then provide the relevant portion of the conversation as input to the selected machine-learning model. The machine-learning model can generate an output based on the relevant portion of the conversation. The system can transmit the output to the user in a response to the query.

  • Publication number: 20260073924
    Abstract: Techniques for video conference transcript querying using artificial intelligence are provided. In an example method, a video conference provider joins a client device to a video conference. The video conference provider receives a deletion election. The video conference provider receives an audio stream from the client device and generates a portion of a transcript of the video conference. Prior to the video conference concluding, the video conference provider processes the portion of the transcript to configure a large language model (“LLM”) to respond to queries based on the video conference. The video conference provider receives a query relating to the video conference and causes the LLM to process the query and the portion of the transcript. The video conference provider outputs a response, generated by the LLM, to the query. The video conference provider then deletes the portion of the transcript based on the deletion election.

  • Patent number: 12499894
    Abstract: Techniques for video conference transcript querying using artificial intelligence are provided. In an example method, a video conference provider joins a first client device of a plurality of client devices to a video conference hosted by a video conference provider. The video conference provider receives an audio stream from the first client device and generates, based on the audio stream, a portion of a transcript of the video conference. The video conference provider processes the portion of the transcript to configure an AI service to respond to queries based on the video conference. The video conference provider receives a query relating to the video conference and causes the AI service to process the query and the portion of the transcript. The video conference provider outputs a response, generated by the AI service, to the query. The video conference provider then deletes the transcript, responsive to the video conference concluding.

  • Publication number: 20250298817
    Abstract: Example methods and systems for prompt enhancement are provided. A communication platform accesses an initial meta prompt. The initial meta prompt is a prompt for a generative model to enhance a task prompt. The communication platform generates a first set of variant meta prompts using a first generative model based on the initial meta prompt. The communication platform generates a first set of enhanced baseline task prompts corresponding to a set of baseline task prompts using a second generative model based on the first set of variant meta prompts. The communication platform evaluates the first set of variant meta prompts to obtain a first set of evaluation data. The communication platform selects a first variant meta prompt as a first optimized meta prompt based on the first set of evaluation data. The communication platform provides the first optimized meta prompt to a third generative model for task prompt enhancement.

  • Patent number: 12407780
    Abstract: A contact center server obtains historical contact center data of a contact center by tracking contact center conditions. The contact center server trains, based on the historical contact center data, multiple modeling engines to generate agent demand data representing a number of agents working at a given time. The contact center server trains, based on the historical center contact center data and performance data of the multiple modeling engines, a combination engine to generate a combination of one or more modeling engines from the multiple modeling engines. The contact center server provides an output representing the trained combination engine and the multiple modeling engines.
