Chord ai vs Chord Analyser

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.

Chord Analyser identifies chords entered as notes on a piano keyboard or fretboard, then shows playable positions for the selected chord. Its library recognizes over 3,500 chords, and its chart editor supports measures, subdivisions, repeats, time and key signatures, playback, auto voicing, and PDF export. The free version costs nothing, has no time limit or ads, and includes one chord chart. More charts require the full version, a one-time payment whose price comes from the app store. That version adds eight instruments, open tunings, MIDI input, unlimited charts, and chart transposition. Microphone recognition is an Android-only beta; it identifies one chord at a time and may struggle on older phones. The maker says audio transcription happens on-device without an internet connection. The app is available for Android and iOS and is described for learners, composers, performers, and musicians who play across instruments.
