Chord ai vs SongEngine

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.

SongEngine creates chord progressions and generates matching basslines, phrases, and melodies. Users can make chords with Chord Pads, import MIDI progressions, or generate progressions in the plug-in. Its free core includes 60+ presets for basslines, arpeggios, phrases, and melodies. Live Mode turns MIDI chords sent from a keyboard or DAW into new MIDI phrases in real time. Generated parts can be dragged into a DAW as standard MIDI files; an optional MassExporter can write hundreds of phrases to a computer folder. SongEngine runs as a VST2, VST3, or AU plug-in and needs a compatible host such as FL Studio or Ableton Live. It supports 64-bit Windows 7, 8, 10, and 11, and macOS 10.13 or later on 64-bit Intel or Apple Silicon processors. There is no official Linux build, though the manual says users have reported using Wine. The maker says its algorithms were crafted by human musicians, not AI, and generated MIDI files may be used in commercial releases.
