## AI overview

Fyxer built an AI executive assistant that uses OpenAI models, fine-tuning, memory, and user feedback to organize inboxes and draft emails in each user's voice. Its system divides email tasks among dozens of specialized models that use context to predict whether a reply is needed and generate suitable responses.
