About Pianolyze

Pianolyze is a browser-based AI tool that transcribes piano recordings into a visual piano roll in real time. Users can drag and drop MP3, WAV, FLAC, or M4A files, slow playback to study tricky passages, and zoom in to inspect exact notes and voicings.

Review

Pianolyze offers an accessible way to analyze piano performances without installing software or uploading audio to a server. The transcription runs entirely in the browser, so audio and inference stay on your device while you watch notes appear on a clean piano-roll interface.

Key Features

• Real-time piano-roll transcription from common audio formats (MP3, WAV, FLAC, M4A).
• Playback controls including slow-down and precise zoom to study passages note-by-note.
• Client-side processing with local model caching for privacy and offline use.
• Web-based rendering and audio playback for instant use in most modern browsers.

Pricing and Value

The tool is launched as a free offering, making it straightforward for students and hobbyists to try without financial commitment. Because all processing happens client-side, there are no upload fees or ongoing inference charges, which increases its value for users focused on privacy and repeat use. Advanced export or notation features are limited at launch, so users needing formal sheet-music output may find the current feature set incomplete.

Pros

• No installation or account required-works directly in the browser.
• Audio never leaves the device, which is good for privacy-conscious users.
• Useful study tools like slowing playback and zooming help with transcription learning.
• Supports common audio formats and caches models locally for quicker repeat transcriptions.

Cons

• Does not yet provide reliable standard notation export (staff notation) for printed scores.
• Built primarily for piano and chordal instruments; less effective for single-line or noisy ensemble recordings.
• Complex polyphonic passages or recordings with background noise may yield imperfect transcriptions.

Overall, Pianolyze is well suited for piano students, teachers, and curious listeners who want a quick, private way to inspect performances and harmonic choices. Those who need polished sheet-music exports or work with multi-instrument mixes should treat it as a study aid rather than a final transcription tool.
