Fenic

Overview

Fenic is an open-source tool that integrates large language models directly into pandas-like dataframe operations. It allows users to perform semantic joins, filters, and map transformations using natural language descriptions, effectively turning LLMs into first-class operators for data analysis and manipulation. Designed for data scientists and developers, Fenic simplifies complex data tasks that require contextual understanding beyond traditional categorical or numeric boundaries.
