Chord ai vs Harmony Pro

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.

Harmony Pro helps composers and producers explore chord possibilities while a piece takes shape. Its suggestion engine offers Balanced, Conservative, Exploratory, and Jazz Expert profiles, with controls for richness, boldness, modal character, continuity, exploration, and style fit. A progression workspace includes key detection and playback. Users can inspect harmony in keyboard, guitar, and sheet views, and use scale and common-tone controls, reverse chord lookup, a progression generator, and a voicing explorer. Chord audio playback is available. Harmony Pro runs on macOS, Windows, and the web. On macOS and Windows, it is available as AU and VST3 plugins; the maker says the VST3 version is intended for Ableton Live. The maker says the app has no AI. It may ask permission to send minimal usage statistics and technical data, while stating that musical content is not transmitted. Users can change this choice at any time. The listed plan is free.
