Making Music Creation Universal

Compoxer is a free AI melody generator that turns a simple text prompt into an original, royalty-free MIDI melody. Our mission is Making Music Creation Universal — democratizing music composition for everyone, from first-time songwriters to professional producers. Compoxer is built human-first: it is an AI tool that assists composers in their creative process and never replaces human authorship. Read the story in Introducing Compoxer Genesis 1.0.

Compoxer Genesis 1.0 is our first generative music model. It converts a natural-language text-to-MIDI prompt — optionally guided by vibe, tempo, key, major/minor mode and duration — into an original melody delivered as a standard MIDI file. It is completely free, available 24/7, with a fair-use limit of 10 generations per hour. Explore our News and the launch announcement for the full picture.

Type what you want in plain English — a mood, genre, tempo or reference — then press create. Compoxer Genesis 1.0 composes an original melody and plays it instantly in your browser. Open the advanced controls to fine-tune vibe, tempo (BPM), key, mode and duration. Sign in to save your work and download the MIDI, then edit and arrange it in any DAW. No account is needed to try it — start from the composer at the top of this page.

Yes — Compoxer Genesis 1.0 is completely free, 24/7, with no credit card required and a fair-use limit of 10 generations per hour. There are no subscriptions, paid plans, premium tiers or in-app purchases — every feature is free for everyone. You can generate and preview melodies anonymously; you only sign in when you want to save your compositions or download the MIDI file. Questions about your account or sign-in? Visit Support.

Compoxer gives you a standard MIDI file (.mid), not finished audio. MIDI stores the musical idea — notes, timing, velocity and tempo — so you keep complete creative control: change the instrument, edit any note, and arrange it your way in any DAW. Delivering MIDI keeps the human composer at the center of every decision, which is core to Compoxer's philosophy of empowering rather than automating creativity.

Melodies are provided royalty-free: you can download, modify, reuse and build on them in your own works, including commercial projects. The author is always you — Compoxer is the instrument, you are the musician. As with any creative material, the final legal clearance of a published work remains your responsibility as the author. See our Privacy Policy for details on data, rights and responsible use.

Ethics come first at Compoxer. We design AI as a tool that empowers human creativity and respects the rights of other authors and works — never as a replacement for composers, performers or producers. Your prompts and compositions are private and are never used to train any model. This human-first commitment shapes every feature we ship. Read more about our approach in our policies and across our News.

The MIDI files Compoxer produces import into every major DAW — Logic Pro, Ableton Live, FL Studio, Pro Tools, Cubase, Studio One and Reaper — and any notation software. You can also work directly inside your session on macOS with our companion app, Compoxer Connect, available free on the Mac App Store. Need help getting set up? Visit Support.

Yes. Compoxer Connect brings the whole AI composer inside your workflow on macOS: describe an idea in plain language and every result lands as editable MIDI on the track you're already on. It's available free on the Mac App Store, with no subscription and no card required.

Every melody is original and unique. Compoxer fingerprints the musical content of each generation and checks it against a global registry, so no two requests — from you or any other user — ever receive the same composition. You always get a brand-new melody to make your own. Discover more about how Compoxer works in our launch story.
