Sheet maker is a browser based application for creating, editing, and sharing piano sheet music. Its primary function is to convert uploaded MP3 audio files into piano sheet music using artificial intelligence, with all processing performed locally on the user's computer rather than on external servers. The tool also supports composing from a blank staff, allowing users to add notes by clicking on the staff, adjust pitch and duration through keyboard shortcuts or drag interactions, and edit or delete notes as needed. Users can play back their compositions directly in the browser, save them as PDF files, and access a shared gallery for browsing and sharing sheet music. The application includes a range of editing capabilities. Users can add notes by clicking on empty staff positions, change note pitch by dragging up or down, and delete notes with a right click. Keyboard shortcuts enable semitone adjustments, grid movement, note length changes, undo actions, and toggling between treble and bass clefs. The tool also supports dotted notes and note length selection via number keys. All editing and playback functions are contained within the browser, with no file uploads to external servers. Typical use cases include transcribing existing piano recordings into readable sheet music, composing original pieces from scratch, and sharing completed works with others through the built in gallery. The workflow involves either uploading an MP3 file for automatic transcription or starting with a blank staff for manual composition, followed by editing, playback, and export to PDF. The application is designed for users who need a free, installation free solution for piano sheet music creation and editing. Technical requirements are minimal, as the application runs entirely in the browser. The AI transcription process uses the user's local computing resources, meaning no audio data is transmitted to external servers. For best transcription accuracy, the tool recommends using audio files containing only piano sounds, such as solo piano recordings or piano covers. Users must agree to the terms of service and privacy policy before using the application.
