In-browser, on-device piano transcription: drag & drop audio to get a piano-roll view and slowed playback with no uploads.

On-Device Transcription: Runs the transcription model fully in the browser so audio is processed locally, minimizing latency and ensuring recordings are not uploaded to remote servers.
Drag-and-Drop Audio Input: Accepts common file formats (MP3, WAV, FLAC, M4A) via simple drag-and-drop to quickly start analysis without complex imports.
Piano-Roll Visualization: Generates an interactive piano-roll view of detected notes, showing pitch and timing to help users inspect performance details visually.
Variable Playback Speed: Allows slowing down audio playback to inspect fast passages or subtle timing details while keeping the visual transcription synchronized.
Local Privacy by Design: Architecture avoids cloud uploads, making the tool suitable for users concerned about confidentiality of recordings and intellectual property.
Immediate, Low-Latency Analysis: Browser execution provides near-instant transcription and visualization for rapid iteration during practice or review.
On-device piano transcription performed in the browser (no uploads to a server)
Drag-and-drop support for MP3, WAV, FLAC, M4A audio files
Piano-roll visual representation of detected notes
Playback controls including slow-down for practice and analysis
Local processing to preserve user privacy and eliminate file transfers

Practice Analysis: Students and teachers can upload practice recordings to inspect missed notes, timing, and articulation using the piano-roll and slowed playback.
Performance Review: Pianists can quickly analyze live or recorded performances for phrasing and timing issues without sending files to third-party servers.
Music Transcription Prep: Musicians can extract note-level information from recordings as a starting point for creating scores or MIDI arrangements.
Rehearsal Feedback: Teachers can generate visual feedback for pupils showing where notes deviate from intended pitches or rhythms during lessons.
Research & Analysis: Music researchers can use on-device transcriptions to study performance characteristics across takes while preserving data privacy.
