Chord ai
Mobile app that listens to any song and prints its chords, beats, and key.
Chord ai does one job — read the chords and beats off a recording — and does it in the place you actually practise, your phone. The chord vocabulary it claims goes past triads into sevenths, diminished and augmented territory, which is where most cheap chord apps fall over. Stem separation, Basic Pitch MIDI export and Whisper lyric transcription are bundled in the same app, so you are not paying for three subscriptions. Where it does not compete: full music-theory analysis, DAW workflows and browser use. If you want the chord chart on a laptop screen, look at desktop transcription tools instead — for playing along on guitar or piano, this is the better fit.

Skip Chord ai if you need chord analysis inside a desktop DAW, a browser tab, or a scripted pipeline over hundreds of files — the documented product is a one-song-at-a-time iOS and Android app.
The free tier is capped at a limited number of analyses per day, so a heavy practice session will hit the ceiling before you finish.
Chord ai sits at the low end of music-analysis software: a free entry tier plus a one-time full-version unlock, against subscription-priced DAW-adjacent transcription tools and desktop stem separators that bill monthly. For a solo guitarist or teacher, the one-off full version undercuts a year of most monthly alternatives; for a studio needing batch processing or DAW plugins, more expensive dedicated tools are the better spend.
In short
Chord ai — Mobile app that listens to any song and prints its chords, beats, and key. Best for Guitar and piano players learning songs by ear, Beginners who need chord diagrams on screen, Songwriters analysing chord progressions. Free to use.

About Chord ai
Chord ai is an iOS and Android app that pulls chords, beats and key from a song automatically. You load audio from YouTube, SoundCloud, a file on your device, or point your phone's microphone at whatever is playing, and it returns a chord chart with downbeat-segmented bars. Guitar, piano and ukulele diagrams are generated for every detected chord. On top of analysis it adds multitrack instrument separation into four stems (bass, vocals, drums, other) with .wav export, audio-to-MIDI conversion built on Spotify's Basic Pitch research, and lyrics transcription using OpenAI's Whisper model. The vendor reports over 500,000 users with a 4.7+/5 average rating across the Apple App Store and Google Play. It is a practice and learning tool, not a DAW: there is no browser or desktop version documented in the material, and nothing describing a public API. It suits guitarists and pianists learning songs by ear, songwriters checking progressions, teachers building lesson charts, and producers who want a quick stem split from a full mix.
Behind the Verdict
Chord ai's pitch is narrow and honest: it manufactures chords, beats and key from audio, then draws them on a fretboard or keyboard diagram so you can play along immediately. The input story is the practical bit. YouTube and SoundCloud links, local audio files, or the device microphone for real-time recognition while you play — that last one is what separates it from static chord websites, since you can strum and have it correct you. Accuracy claims in the scraped reviews go beyond basic triads: one reviewer specifically calls out major sevenths, dominant sevenths, diminished, augmented and altered dominants being detected correctly. That matters, because extended harmony is exactly where automated chord recognition tends to collapse into a mess of generic majors. Beyond recognition, the app bundles three things usually sold separately. Multitrack separation into four stems — bass, vocals, drums, other — with individual .wav export. Audio-to-MIDI conversion based on Spotify's Basic Pitch research. And lyric transcription via OpenAI's Whisper model. All three are named techniques from named research groups, not vague 'AI-powered' labels. The honest constraints: everything in the evidence describes a mobile app. No web app, no desktop client, no documented public API. The vendor side is Nomad AI and Bellec Research, with contact routed through an in-app form, Facebook, Instagram, YouTube and Twitter. There is no developer portal in the material. One reviewer in Japanese notes the free tier is good on its own but that a regular user should buy the full version — and asks for larger chord text in exported PDFs. There is also no batch processing story: this is one song at a time. Where it fits: the guitarist learning a song tonight, the piano beginner who needs the diagram, the songwriter checking what a progression actually does, the teacher building lesson sheets, the producer wanting a quick stem grab. Where it doesn't: anything resembling theory analysis at depth, anything inside a DAW, anything laptop-first, and anything requiring volume processing.

Real-world workflow fit
Concrete scenarios for the personas Chord ai actually fits — and what changes day-one when you adopt it.
You want to play along with a track you found on YouTube but the chords online are wrong.
Outcome: You paste the YouTube link into Chord ai, get a chord chart segmented into bars with ukulele or guitar diagrams, and play along to the original recording.
You can hear the song in your head but cannot identify the chords by ear yet.
Outcome: You load the audio file, read the piano chord diagrams for each detected chord, and use the key detection to know which scale to practise in.
You need the vocal isolated for a remix but only have the mastered stereo file.
Outcome: You run instrument separation in the app, export the vocals stem as .wav, and pull it into your DAW session.
Use Cases
- Paste a YouTube link and get a chord chart to play along with the recording.
- Hold your phone up while you play guitar and see chords detected in real time.
- Split a track into bass, vocals, drums and other to practise one part in isolation.
- Export a stem as .wav to drop into your own project.
- Convert a hummed or played melody into a MIDI track for further editing.
- Transcribe a song's lyrics for karaoke or study.
- Work out the key and chord progression of a song before writing over it.
Models Under the Hood

Limitations
- The evidence describes a mobile-only product: iOS and Android.
- No web app, desktop client or public API is documented in the material, so anything laptop-first or scriptable is out of scope.
- Analysis runs one song at a time — there is no batch processing described.
- The harmonic output stops at chords, beats and key; there is nothing here for voiced-leading analysis, functional harmony or score-level notation.
- Instrument separation is capped at four stems (bass, vocals, drums, other) with .wav export and no individual track mixing controls described.
- Audio-to-MIDI runs through Spotify's Basic Pitch, which is a monophonic-leaning transcription approach.
- Lyrics come from Whisper, so accuracy tracks that model on sung material.
- One user review asks for larger chord text in PDF exports.

Where the pricing makes sense
The company stage and team size where Chord ai's pricing actually pencils out — and where peers do it cheaper.
Chord ai sits at the low end of music-analysis software: a free entry tier plus a one-time full-version unlock, against subscription-priced DAW-adjacent transcription tools and desktop stem separators that bill monthly. For a solo guitarist or teacher, the one-off full version undercuts a year of most monthly alternatives; for a studio needing batch processing or DAW plugins, more expensive dedicated tools are the better spend.
Setup time & first value
How long it actually takes to get something useful out of Chord ai — broken out by persona, not the marketing-page minute.
Fast. Install the iOS or Android app, open it and pick a source — a YouTube or SoundCloud link, a file from your device, or the microphone. First chord chart is available after a single analysis pass; there is no account setup, no plugin install and no routing to configure. Real-time microphone recognition works as soon as you grant mic permission, and it explains its own output through the chord
Switching to or from Chord ai
