Feeding PDFs to an AI support agent?
helpGPT answers your customers' questions from your own docs, with citations and honest refusals.
One file per bookmark
Ebooks, manuals, and reports already carry their chapter map as bookmarks. Split on them and each chapter downloads as its own PDF, named after its bookmark.
Local split, no upload
Bookmark reading and splitting run entirely in your browser. Your documents are never uploaded to any server.
Frequently asked questions
