Chord ai vs PianoConvert

Chord ai is a mobile app that recognizes chords and beats in songs, helping listeners follow music or learn to play it. Songs can be loaded from YouTube, SoundCloud, audio files, or a device microphone. The app detects chords, tracks beats and downbeats, displays tempo and song structure, and infers a song's key; it also shows guitar, piano, and ukulele chord diagrams. Microphone input can identify chords in real time. The maker describes on-device deep learning, with audio files and microphone input analyzed on the phone. The free plan provides basic features with unlimited free use. Chord ai Pro adds recognition of more than 700 chords, voicing and position suggestions, unlimited saved songs, PDF transcription export, score editing, and WAV export of bass, drums, vocals, and other stems. Other Pro tools include pitch shifting, alternate tunings, smart capo suggestions, and processing audio or video up to one hour at once. Pro costs $9 a month or $69 a year, with prices depending on App Store country. The app is available on Android and iOS, and the maker does not provide API access to its technology.

PianoConvert is a web service that turns audio or YouTube videos into piano sheet music. Its transcription mode reproduces an audible piano performance, while arrangement creates a playable piano version of a song. Inputs include YouTube links, MP3, WAV, MP4, and AAC files, plus direct browser recording. PianoConvert says it identifies polyphony, tempo, measures, and clefs automatically. After conversion, users can preview and edit the score, then export it as PDF, MIDI, or MusicXML. Those formats are described as compatible with MuseScore, Dorico, Sibelius, Finale, Cubase, and Logic. The maker says an average-complexity score takes about two minutes to convert. For transcription, piano must be clearly audible; dense mixes or poor-quality recordings can reduce fidelity. Free use covers only the first 30 seconds of each song, while full scores require a subscription. Plans range from free to €14 a year, billed annually. PianoConvert was founded in 2017 and is based in Cergy, France.
