ChordGen is a free, browser-based AI-powered chord progression generator that turns plain-language prompts (like "melancholic jazz" or "upbeat pop anthem") into multiple, genre-aware progressions you can hear on an interactive piano, edit visually, and export as MIDI for any DAW with no sign-up; its AI composes and adapts harmonies to your prompt so songwriters, producers, and learners can quickly overcome writer’s block, explore new styles without deep theory, and jump straight to production-ready MIDI.
