OpenAI has published a case study on Fyxer, a company building an AI executive assistant. Fyxer runs on OpenAI models and adds fine-tuning, memory and feedback collected from real users.

The assistant does two things: it organizes the inbox and it drafts emails. Those drafts are not written from a generic template, they follow each user's own voice. According to OpenAI, Fyxer shapes this behaviour through user feedback and a memory layer, so the assistant keeps track of how a given person writes.

OpenAI frames the piece around trust: a system that writes on someone's behalf in a space as personal as email only gets accepted if it gets the voice right.

Beyond these points, the source gives no technical breakdown, pricing or availability details. The full write-up is on [OpenAI's page](https://openai.com/index/fyxer?ref=globalfeed.ai).
