Doctran

Doctran is a python package. It uses LLMs and open-source NLP libraries to transform raw text into clean, structured, information-dense documents that are optimized for vector space retrieval. You can think of Doctran as a black box where messy strings go in and nice, clean, labelled strings come out.
