Chord ai vs Melody Scanner

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.

Melody Scanner automatically turns songs into sheet music. Users can record an instrument, import MIDI, MusicXML or MP3 files, or generate scores from YouTube videos. Scores can be edited in classical notation, piano roll or guitar tabs views, with PDF export available. Listed modes include piano, guitar, flute, violin, saxophone, bass, singing and chords. The maker says piano mode supports polyphony, velocity and hand separation, with accuracy up to 86%; smart editing can help transpose scores and label chords. The app runs in a browser without installation and is also listed for iOS and Android. The free plan allows recordings up to one minute and sheets limited to 40 bars or about two minutes. Monthly access is $9.99 a month; the yearly subscription is $49.99 a year, billed annually. Paid plans list recording up to five minutes, full sheets and MIDI/MusicXML export. The product currently supports solo instruments, not bands or orchestras.
