ChordPrompter is a web based tool and Android application designed to display guitar chord diagrams directly within song lyrics. Its primary function is to serve as a teleprompter for musicians, eliminating the need to switch between separate screens for lyrics and chord references. The tool presents visual chord diagrams inline with the text, allowing performers to see both the words and the finger positions for each chord simultaneously. The application operates entirely within a web browser for free, with a dedicated Android app available for stage use. Key capabilities include the display of chord diagrams embedded in lyrics, which helps musicians maintain focus during practice or live performances. The tool is designed to streamline the workflow of learning and performing songs by consolidating all necessary musical information into a single, scrollable view. Typical use cases include live performances where a musician needs to reference chords without looking away from the lyrics, as well as practice sessions for learning new songs. The workflow involves loading or inputting lyrics with chord notations, after which the application automatically generates and positions the corresponding chord diagrams. Technical requirements are minimal for the browser version, requiring only an internet connection and a modern web browser. The Android app is intended for offline use on stage, providing a dedicated mobile experience.
