Prompt Preparer is a free Chrome extension designed to facilitate the construction and formatting of prompts for Large Language Models (LLMs). This tool features a floating overlay that remains accessible as you navigate through different pages, ensuring a smooth and uninterrupted workflow. Users can benefit from quick insertion buttons for Markdown headers, XML tags, and frequently used prompt patterns, making it easy to create complex prompts efficiently. Additionally, the extension allows users to save templates for quick access, manage their prompt history with undo/redo functionality, and copy formatted prompts to the clipboard with a single click.
The interface is draggable, allowing users to position the overlay anywhere on the screen for maximum convenience.
