Autochords vs Chord ai

Autochords is an iPhone and iPad app that helps songwriters find chord progressions and learn chords on guitar, piano and ukulele. Choose a progression style and key to see a main progression and alternatives for other song sections. Progressions can be previewed at a selected tempo with piano, guitar or ukulele playback, and the app provides diagrams for each instrument. Its built-in library contains dozens of progressions across styles of western music, though some require PRO. The free plan provides the app's free features. PRO adds more progressions, favorites, tempo changes, color themes, custom progressions and MIDI export. Export uses the iOS share sheet to open files in compatible apps, including desktop DAWs such as Logic or GarageBand. PRO costs $2.99 a month, $12.99 a year or 29.99 USD once for lifetime access. If a PRO subscription expires, existing favorites and custom progressions remain accessible, but users cannot add or remove favorites or create or delete custom progressions. Astrocode Pty Ltd develops the app, which is operated by a solo developer.

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.
