Chord ai vs Drum2Notes

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.

Drum2Notes uses AI to turn drum recordings or songs into sheet music. You can record audio, upload an MP3, or supply a YouTube link. The product says it detects snare, toms, bass drum, and cymbals played at the same time, including when other instruments are present. Notes can be adjusted in Edit Mode, and exports include PDF sheet music, quantized or unquantized MIDI, and MusicXML. The free demo covers the first 20 seconds of a recording and can be repeated as often as desired; full transcriptions are available through Pro. The product page lists paid plans from $14.99/mo, while the Pro plan price was not listed. Drum2Notes runs in a browser and has Android and iOS apps, with transcription synchronization between web and mobile. The maker notes that results depend on the source music and may need correction in Edit Mode. It supports audio up to 15 minutes. The product page directs users to a Help Center and Support Chat and advertises a 14-day money-back guarantee.
