How does a chord finder work?
A chord finder matches notes you select or perform to known chord patterns. For full songs, the audio analysis service returns timestamped chord estimates from an uploaded recording.
What is the difference between a chord finder and a chord identifier?
A chord finder can look up chords by name, instrument, or notes. A chord identifier normally names a chord based on the notes you enter or play.
Can I identify a chord by selecting notes?
Yes. Open our free chord identifier and select notes on the virtual keyboard. Matching chord names update immediately.
Can I identify chords from sound?
Our microphone tool offers experimental single-chord recognition. Results depend on your device, recording quality, and tuning; always verify by ear.
Can I upload an MP3 to find a song’s chords?
Yes. Upload MP3, WAV, M4A, OGG or FLAC audio and press Find Chords to receive timestamped estimates when the analysis service is configured. Files are not sent until you start analysis. Phone audio uploads directly to the chord service, and results return to this browser.
Can I analyze a YouTube video without downloading it?
The YouTube link input is temporarily unavailable. Upload an MP3, WAV, M4A, OGG or FLAC recording to find timestamped chords.
What audio formats are supported?
The upload tool accepts MP3, WAV, M4A, OGG and FLAC files up to 30 MB. Browser playback support varies, while the analysis server decodes the uploaded file for processing.
How accurate is chord detection?
Exact-note matching is deterministic within its supported chord vocabulary. Song-level chord recognition provides estimates; we have not published a measured accuracy benchmark, so verify results by ear.
Is AI Chord Finder free?
The currently available note identifier and chord chart tools are free to use without an account. Future AI processing limits or pricing have not been determined.
Is this a Chordify alternative?
For learning chord shapes and identifying chords from selected notes, yes. It is not yet a substitute for the song-synchronized audio analysis features of Chordify.
