Pianopedia - AI Piano Coach

Pianopedia is a personal piano coach that helps you read, practice, and explore music. The whole app speaks both English and Simplified Chinese, and every score renders in Western staff notation or Chinese jianpu.

Capture a printed score with your camera and turn it into a practice piece you can play back, read along, and score in real time.

WHAT YOU CAN DO

Build your library
Scan printed sheets, import photos, paste a MIDI or MusicXML URL, or type a piece in by hand. Pianopedia records tempo, key, time signature, and difficulty for every piece.

Practice the classic method books
The public-domain piano curriculum is built in: Beyer Op. 101, Czerny Op. 599 and Op. 849, Hanon, Burgmüller Op. 100, and Bach's Notebook for Anna Magdalena — over 330 playable exercises and studies, organized chapter by chapter and playable with the same Read, Demo Play, and Practice tools.

Three ways into every piece
Read mode lays the score out like a printed music book you scroll at your own pace, with pinch to zoom, so the phone can sit on the music rack. Demo Play performs the piece with every note lit on a full 88-key keyboard. Practice listens through the mic and scores you in real time.

Practice with real-time scoring
Pianopedia tracks every pitch and scores accuracy and timing — right and left hand graded independently. A built-in count-in, metronome, and tempo multiplier let you start slow and build to full speed. Choose Listen, Play Along, or Guided mode.

Read in staff or jianpu
Switch the entire app between Western staff notation and Chinese jianpu. The renderer redraws every piece on the fly, with optional fingering hints and engraved sustain-pedal marks.

Recognize printed scores with AI
Point your camera at a printed score and Pianopedia extracts notes, rhythm, key, and time signature with a vision language model. Bring your own API key for Anthropic Claude, Google Gemini, xAI Grok, or OpenRouter, or use the built-in on-device recognizer offline.

Search scores across genres
Search six free libraries — Mutopia, piano-midi.de, and mfiles for public-domain classical, POP909-CL and JustPiano for Chinese-language pop, and VGMIDI for video-game arrangements (Final Fantasy, Zelda, Mario). Search by composer, opus, BWV / K. number, artist, or title in either language — "Moonlight" and "月光" both find Beethoven's Op. 27.

Premium piano sound, optional
The app ships with a sampled grand piano. From Settings you can install FreePats Acoustic Grand (CC0) or Steinway D-274 (CC-BY 3.0) for richer tone — each downloads once and swaps in instantly.

Free play
A full 88-key keyboard lets you play any pitch on the spot, with realistic tone.

Practice history
Every session logs date, duration, pitch and timing scores, and a graded summary. Track your daily streak and progress over time.

Tools and knowledge
A built-in metronome with classical tempo terms (Largo through Presto), multiple click sounds, accent patterns, subdivisions, and tap tempo. Plus a bilingual knowledge library covering technique, theory, terms, practice, and the lives and works of fourteen major composers from Bach to Rachmaninoff.

Privacy first
All practice audio is processed on your device. Pianopedia never uploads recordings of your playing. Photos are sent to your chosen cloud provider only when you explicitly enable cloud sheet recognition and supply your own API key. The app does not operate a backend.

iCloud sync, optional
Turn on iCloud sync to back up your library and access it from every device signed into your Apple ID.

Free to try, one-time unlock
Practice, Read, Demo Play, free play, the metronome, method books, and the knowledge library are always free and unlimited. A small one-time in-app purchase unlocks unlimited catalog downloads after a generous free trial — no subscription, no account.

Pianopedia is built for piano students, returning amateurs, and lifelong learners who want a thoughtful, focused practice companion — not a game, not a leaderboard.
