An AI chord progression generator suggests harmonically sensible chord sequences for a key, mood, or genre — and the best ones let you export the result as MIDI straight into your DAW. They’re a fast cure for writer’s block and a great way to discover progressions outside your usual habits. This guide covers what to look for and walks through the main tools worth knowing.

Quick answer
If you want a chord engine baked into a free DAW with one-tap song ideas, BandLab SongStarter is the easiest start. For text-driven suggestions and theory explanations, ChatGPT is surprisingly capable. Dedicated generators and plugins give you the most control and MIDI export. The right pick depends on whether you want playable MIDI, in-the-box convenience, or learning value.
How to choose an AI chord progression tool
Not all of these do the same thing. Weigh these factors before committing:
- MIDI export: the single most important feature for producers. If you can drag the chords into your DAW as MIDI, you can voice, swap sounds, and edit freely.
- Key and scale control: good tools let you lock a key, choose major/minor or modes, and constrain suggestions to what fits.
- Mood and genre presets: handy for getting in the right ballpark quickly.
- Voicing and rhythm options: a flat block-chord output is a starting point; the better tools suggest inversions, extensions, and rhythmic patterns.
- Learning value: tools that show Roman-numeral analysis teach you why a progression works, so you rely on them less over time.
- Integration: a plugin inside your DAW beats a separate web app for flow.
The tools worth knowing
BandLab SongStarter
BandLab’s free SongStarter generates a quick musical idea — including chords — that you can open and build on inside BandLab’s DAW. It’s aimed at sparking starts rather than fine control, which makes it ideal for beginners and fast sketching. Our pick for free, beginner-friendly starts. It’s the easiest no-cost way to get a chord-based idea going without any setup.
ChatGPT and general AI assistants
Ask ChatGPT for a progression in a key, genre, and mood and it returns options with theory analysis you can learn from. The catch: it outputs text, not MIDI, so you’ll play the chords in yourself. For the full approach, see how to use ChatGPT for music production.
Dedicated chord plugins and apps
A category of DAW plugins and standalone apps focuses purely on chord generation and voicing, with MIDI drag-out, scale locking, and rhythmic strumming patterns. These give producers the most control and fit cleanly into a session. At the time of writing the specific feature sets change often, so check current capabilities before relying on any one feature. Our picks here. Scaler 2 is the best-known for chord suggestion, voicing and scale work; Captain Chords (part of Mixed In Key’s Captain suite) and Orb Producer Suite are strong alternatives; and Hooktheory’s Hookpad is great if you want to learn the theory as you go. Pros: MIDI drag-out and scale locking fit cleanly into a session and give producers the most control. Cons: paid plugins with a learning curve, and feature sets shift, so confirm current capabilities first.
Full-song generators (Suno, Udio)
Tools like Suno and Udio don’t hand you a chord chart, but they generate complete tracks whose harmony you can learn from or use as a reference. If your goal is a finished song rather than raw chords, our best AI music generators roundup is the better starting point.
Web app vs DAW plugin: which workflow fits you
One of the biggest practical decisions is where the tool lives. A web app is quick to try and needs no installation, but you’ll be copying chords or exporting files and dragging them into your project — extra steps that interrupt flow. A DAW plugin or DAW-native feature keeps everything in one session, so a progression you like is a drag away from being voiced, re-sounded, and arranged. If you write in long, focused sessions, the plugin route usually wins; if you just want occasional inspiration on the go, a web app is fine. Beginners often start with an in-DAW option like BandLab SongStarter precisely because it removes that friction.
Common mistakes to avoid
A few habits stop people getting value from these tools. The first is accepting the first suggestion — generate several and compare, because the interesting one is rarely the first. The second is leaving chords as flat held blocks; rhythm and voicing are what make a progression feel like music. The third is ignoring the theory the tool shows you. If a generator gives Roman-numeral analysis, read it: understanding why a borrowed chord or a secondary dominant works is how you eventually stop needing the tool for everyday writing. Treat each suggestion as a small lesson, not just a result.
Turning AI chords into real music
A progression is a skeleton. To make it yours, change the voicings (spread the notes, add a 7th or 9th), give it rhythm instead of held blocks, and choose a sound that fits the song. Pair the harmony with a melody — our AI melody generators guide helps there — and consider the lyric on top via how to write lyrics with AI. The AI gives you a sensible start; the musical decisions are still yours.
Should you rely on AI for chords?
Use it to break habits and learn, not to outsource your ear entirely. The producers who get the most from these tools treat suggestions as prompts — keeping what surprises them, discarding what feels generic, and gradually internalising the patterns so they need the tool less.

Frequently asked questions
Can AI chord generators export MIDI?
Many can, and that’s the feature to prioritise as a producer — it lets you re-voice and re-sound the chords freely in your DAW. Text-based tools like ChatGPT give you the chord names instead, which you then play in yourself.
Are AI chord progressions copyrightable?
Short, common chord progressions generally aren’t protectable on their own regardless of how they’re made, since many songs share the same chords. This is general information, not legal advice, and the wider question of AI-assisted work is unsettled — see can you copyright AI music.
Will using AI chords make my music sound generic?
Only if you stop at the raw output. Re-voice, add rhythm, and pair the chords with a strong melody and arrangement, and the source of the progression becomes irrelevant — what listeners hear is your production.
