About ChatGPT Enhancement Extension

An all-in-one open-source Chrome extension that enhances the ChatGPT web interface with prompt hints, PDF document support, Markdown export, and a customizable admin dashboard. Users can type '/' to trigger prompt suggestions, drag-and-drop PDF files for automatic page-by-page prompt generation, and convert dialogues to Markdown. The extension includes injection buttons for copying, saving, and exporting conversations, an admin page for managing prompt groups and settings, and omnibox integration (type '.' in address bar) to ask ChatGPT quickly. It also allows selecting text from any webpage to re-prompt ChatGPT directly, and supports custom keyboard shortcuts. Recommended to be used alongside KeepChatGPT to mitigate connection errors.
