Conversation categorizer

Drop an AI chat export — Claude or ChatGPT JSON, or a CSV with a text column — and see what you actually use AI for, sorted into 12 topic categories. It runs entirely in your browser: nothing is uploaded.

This is a light version of the GenAI Categorizer. The full project adds embeddings, clustering, and charts you can run over your whole history locally.

or drag & drop .json / .csv files here
