Our verdict on Compoxer
Compoxer is a browser-based AI melody generator for songwriters, composers, and music producers who want editable MIDI starting points. Natural-language prompts can describe a melody while controls set vibe, tempo, key, major or minor mode, and duration. Generated ideas can be previewed in the browser, then saved or downloaded as standard MIDI files after signing in. Its stated fit is solo and small teams working across browser and desktop music-production workflows.
Genesis 1.0 is described as fully free, with no paid plans, and the published fair-use limit allows up to 10 melody generations per hour. That makes Compoxer suitable for sketching ideas without a subscription commitment. MIDI files can be imported into major DAWs and notation software, including Logic Pro, Ableton Live, FL Studio, Pro Tools, Cubase, Studio One, and Reaper. Compoxer Connect is presented as a macOS plugin that places editable MIDI into a DAW session, with VST3, AU, and AAX formats listed.
The workflow is focused on melody generation rather than harmonic composition. Category specifications list basic chord and scale awareness, key or scale locking, and no chord progression input, so users who need generation guided by an existing progression may need another tool or a DAW-based process. Browser preview and downloadable MIDI suit rapid drafting, while Connect is specifically described for macOS. Choose Compoxer for free, prompt-led melody sketches and straightforward MIDI handoff; look elsewhere if chord-progression control or a broader standalone composition environment is central to your work.
