Review comment (suggestion):
Actually, sorry, something occurred to me after the fact- with a lengthy-enough conversation, it may be difficult to immediately tell what lines in the export file are from the user and what lines are from the model. Could this be included in the output to help disambiguate? 

(A more involved change would be to pattern off of the representation in the OpenAI API, e.g., a messages JSON array with role / content sections.)
