Any chat in your history that is still available.
CHATGPT.Vellum turns it into a readable, titled document.
Build a tidy archive of PDFs, one per conversation.
The official export is a JSON archive; CHATGPT.Vellum gives you documents a person can read.
Each conversation is captured in full, however long.
Exports are built locally and never uploaded.
One clean PDF per conversation, easy to file and search.
It is the file in ChatGPT's official data export. It holds your chats as raw data, not readable documents.
CHATGPT.Vellum exports your live conversations to PDF one by one; it does not upload your archive, which keeps things private.
If you want to keep your chats, save the ones that matter as PDFs first.
