Chord ai vs Piano2Notes

Chord ai is a mobile app that recognizes chords and beats in songs, helping listeners follow music or learn to play it. Songs can be loaded from YouTube, SoundCloud, audio files, or a device microphone. The app detects chords, tracks beats and downbeats, displays tempo and song structure, and infers a song's key; it also shows guitar, piano, and ukulele chord diagrams. Microphone input can identify chords in real time. The maker describes on-device deep learning, with audio files and microphone input analyzed on the phone. The free plan provides basic features with unlimited free use. Chord ai Pro adds recognition of more than 700 chords, voicing and position suggestions, unlimited saved songs, PDF transcription export, score editing, and WAV export of bass, drums, vocals, and other stems. Other Pro tools include pitch shifting, alternate tunings, smart capo suggestions, and processing audio or video up to one hour at once. Pro costs $9 a month or $69 a year, with prices depending on App Store country. The app is available on Android and iOS, and the maker does not provide API access to its technology.

Piano2Notes uses AI to turn piano audio into sheet music, MIDI, or MusicXML. Users can record in the app, upload an audio file, or supply a YouTube link. It is designed to transcribe melodies and chords, including piano parts in recordings with other instruments. A built-in editor lets users adjust notes, timing, and layout, while Piano Roll mode provides a view for playing along. Exports include PDF sheet music, quantized or unquantized MIDI, and MusicXML, which the maker says can be used with notation software and DAWs. The free demo covers only the first 20 seconds of each recording, file, or video. Piano2Notes Pro costs $14.99 a month and includes 50 full transcriptions monthly, each up to 15 minutes. The maker says results work best with well-recorded, piano-focused music and offers an editor for correcting small errors. Piano2Notes is available on Android, iOS, and web, and work syncs between desktop and mobile platforms.
