ChordCraft vs Chordio

ChordCraft is a free web-based chord progression generator for producers and musicians. Users choose a genre and mood, then generate progressions with humanized playback and real instruments. The generator lists 10 genres, including Pop, Lo-fi, Jazz, EDM, Rock, R&B, Ambient, Cinematic, Bossa Nova and Hip-Hop, plus eight moods from Happy and Sad to Epic and Mysterious. Voice leading is available, and chords can be edited or locked. Advanced controls cover key selection, chord length and voicing modes. Multiple sections can be combined into a full arrangement. Saved progressions can be exported or imported. Export formats are WAV, stems and MIDI. The Free plan costs nothing and includes those export formats, while listing free generations remaining today. ChordCraft also provides chord audio playback.

Chordio is a music composition and theory app for iOS and macOS, with workspaces for composition, scales, modes, sheet music, music theory and lessons. Its library includes more than 40 scales. Connect a USB, MIDI or Bluetooth MIDI keyboard and it identifies chords in real time, naming them on the grand staff. Harmony Explorer finds matching scales and suggests diatonic and borrowed chords, secondary dominants and tritone substitutions. Progressions can be dragged into Logic Pro, Ableton Live, FL Studio and other DAWs as MIDI; MIDI chords can also be imported for re-harmonization. Sheet Music includes tempo adjustment, looping, separate-hand practice, transposition and PDF printing. Lesson Packs let users play pieces in any key and at any tempo. The free download includes built-in sounds, an on-screen keyboard and every workspace. Full Unlock costs $14.99 as a one-time purchase and includes Mac, iPad and Vision Pro, plus lifetime updates. The iPhone version is purchased separately, and there is no Android app.
