A system for using generative AI to automate electronic communication responses includes receiving, from an initiating entity, an electronic communication at a receiving entity. The system provides the electronic communication to a large language model (LLM). The system provides instructions to the LLM, causing the LLM to evaluate the electronic communication to determine whether a meeting is requested, to produce a meeting indicator, to evaluate the electronic communication to determine if there are one or more tasks, to produce a task list, and to produce a responsive electronic communication based on user-defined rules. The system receives a dataset from the LLM. If a meeting is requested, the system identifies mutually available meeting times between the initiating and receiving entities. The system sends a meeting invitation at a mutually available meeting time. The system sends the responsive electronic communication. The system generates the tasks from the task list.
