What it is

ChordU identifies chords in audio and aligns them with musical notation. Users can also find a song on YouTube, copy its link and search for it in ChordU. A song may have simplified, advanced, bass or edited chord arrangements, as well as treble-clef and bass-clef note versions. Chord diagrams cover guitar, piano, ukulele and mandolin. On the website, users can obtain PDF chord and note sheets, MIDI files and synthesized notes in WAV format. MusicOnly mode provides controls for vocals, bass, drums and other instruments, and can export a mixed audio download. Local music uploads and MusicOnly for those uploads require Premium; Premium also permits chord downloads without a stated monthly limit. The Free plan has limited access, while Premium costs $5.00 per month. ChordU is available on Android, iOS and the web. Its terms limit song and chord use to personal, non-commercial purposes.

ChordU in depth

Read the full write-up

Overview

ChordU turns song audio into synchronized chords and notation, and also lets users look up songs through YouTube links. It suits players who want several arrangements and instrument-specific chord diagrams alongside practice and export tools.

Its breadth is useful for moving from song lookup to practice materials, but local uploads and MusicOnly controls for uploaded files require Premium. The personal, non-commercial usage terms also rule it out for commercial work.

Key features

Chord recognition and song lookup

ChordU recognizes chords from audio files and synchronizes them into notation. For YouTube songs, the lookup process starts with a YouTube search: copy the song link and search for it in ChordU. Simplified, advanced, bass, and edited chord versions give players options for different levels of detail and parts.

That range is more useful than a single fixed chord view, particularly for players who want to compare arrangements. ChordU also includes a progression generator and voicing explorer, extending its use beyond looking up an existing song.

Notation, playback, and exports

ChordU supplies treble- and bass-clef note versions, including simple, music, and bass notes. Chord diagrams cover guitar, piano, ukulele, and mandolin, and chord audio playback connects the written material to sound. The website can export chord charts and provide PDF chord and note sheets, MIDI files, and synthesized notes in WAV format.

MusicOnly controls vocals, bass, drums, and instruments, and can export a mixed audio download. This gives users a way to work with a mix rather than only a chord chart, though use of MusicOnly for local uploads is reserved for Premium.

Privacy and support

ChordU says sensitive information is encrypted with SSL and that transactions go through a payment gateway rather than being stored on its servers. Users can request data deletion by email; processing takes up to seven days. Help documentation, sales, technical support, and media inquiries each have contact routes.

Pricing

Free costs nothing and provides limited access features. It is the sensible starting point for song lookup and trying the service, but it does not unlock the Premium-only local upload workflow or MusicOnly for uploaded files.

Starter has custom pricing. It includes paid features, but excludes song uploads and notes/MIDI downloads, so it is a poor fit for users whose workflow depends on those capabilities.

Premium costs $5 a month, billed $ 5.00/Month. It includes all ChordU features, uploads, MusicOnly mode, and downloads. Premium members can download chords without a stated monthly limit, making this the relevant plan for frequent downloading or upload-based work.

ChordU limits song and chord use to personal, non-commercial purposes under its terms. That restriction matters regardless of plan: paying for Premium does not make the material suitable for commercial use.

Platforms

ChordU runs on the web, Android, and iOS. Its website supports chord-chart export and offers PDF, MIDI, and WAV downloads; mobile apps broaden access beyond desktop use.

Who it's for

ChordU is a strong match for musicians who learn songs by comparing chord arrangements, need notation in more than one clef, or want diagrams for guitar, piano, ukulele, or mandolin. Its playback, progression, and voicing tools also suit players exploring harmony as well as following a song.

It is less suitable for anyone who needs commercial usage rights, or who wants local uploads and upload-based MusicOnly without Premium. Starter also misses song uploads and notes/MIDI downloads, so users needing those functions should consider Premium rather than assuming any paid tier includes them.

Pros and cons

Multiple chord and note views: simplified, advanced, bass, and edited chords plus treble- and bass-clef note options support different playing needs.

Useful instrument coverage: diagrams span guitar, piano, ukulele, and mandolin, with chord playback to complement the visual material.

Broad export mix: PDF sheets, MIDI, synthesized WAV notes, and chord-chart export serve different practice and arranging workflows.

Important upload restrictions: local files and MusicOnly for those uploads require Premium; Starter excludes uploads and notes/MIDI downloads.

Personal-use boundary: the non-commercial terms make ChordU unsuitable for commercial song or chord use.

Alternatives

Chord Finder Software is a category list for readers who want to compare chord-finding options rather than start with one product.

OtoTheory is worth considering for iOS and web users who want a free tier with three local sketch saves, or a one-time $99.99 USD Lifetime plan for iOS Pro features; its free tier does not include MIDI or audio export.

HarmonyBuilder is a better direction for Linux, macOS, or Windows users looking for four-part score writing, chord grids, playback, and MIDI export, with a $14.00 USD monthly Basic plan.

Chordio is an iOS and macOS option for users focused on real-time MIDI chord detection, an on-screen keyboard, and built-in sounds; its Free download plan costs nothing.

Harmony Pro is a free option for readers seeking a tool available on macOS and Windows.

Tonaly is an iOS and macOS alternative for users who want in-app purchases for scales or PDF lead-sheet export, including an 80+ Scales option at 3.99 USD once.

Chord ai is an Android and iOS alternative with a free tier and a $9.00 USD monthly Pro plan for advanced features; its free use is stated as unlimited.

Chord Analyser is an Android and iOS option with a free plan described as having no time limit and no ads.

ChordSequence is a free Android and web option for users who want all features without a paywall or usage limit, with WAV and MIDI export.

Verdict

Choose ChordU if you want song-based chord recognition, several notation views, instrument diagrams, and a range of downloadable practice materials across web and mobile. Premium is the fit for local uploads and upload-based MusicOnly, while Starter's exclusions make it a narrower paid choice. Look elsewhere if you need commercial usage rights or unrestricted free uploads.

Verdict

ChordU combines chord recognition, notation options and instrument diagrams, with additional upload and download capabilities under Premium. Its stated usage terms make it a fit for personal rather than commercial use.
