Import audio
Start with a local file or microphone recording. GigaChords focuses on the audio you bring.
Music is opt-in
Private chord detection for real practice
GigaChords listens to your audio, maps the chord changes, and gives you a practice timeline you can transpose, loop, edit, save, and follow in real time.

The workflow
Start with the song you actually want to play.
Most chord apps start with a catalog. GigaChords starts with your audio, then turns it into a readable practice map.
See the changes
Build a chord timeline with current and upcoming chords, beat-aware cells, and readable flow.
Practice smarter
Transpose, set capo, loop difficult parts, save charts, and keep improving the map.
Why it feels different
A chord chart is only useful if you can practice with it.
Follow the current chord, see what is coming next, slow down, loop a section, and keep playing.
Current and next chord diagrams
Keep the current and upcoming chord in view with rotatable guitar, ukulele, and piano diagrams.
Loop, seek, and slow down
Repeat a difficult section, seek on the timeline, and change playback speed while the chart stays in sync.
Editable charts
Automatic detection is a starting point. Correct chord cells and timing by ear, then keep the version you trust.
Feature set
Everything around the chord map serves practice.
Local audio to chord timeline
Analyze a local song file or microphone recording on your device and follow the result with a moving playhead.
Current and next chord diagrams
Keep the current and upcoming chord in view with rotatable guitar, ukulele, and piano diagrams.
Capo and transpose
Move the chart for your voice, guitar shape, or rehearsal key without rewriting the song.
Loop, seek, and slow down
Repeat a difficult section, seek on the timeline, and change playback speed while the chart stays in sync.
Grid and Stage views
Edit the full chord grid, then switch to a focused waveform Stage view with large current and next diagrams.
Save without re-analysis
Build a practice library of chord maps and reopen saved charts without waiting on a fresh analysis.
Built for trust
Honest detection beats magic claims.
Dense mixes, unusual harmony, and fast passing chords can fool any chord detector. GigaChords is tested with real songs, keeps every chart editable, and sets clear product limits.
How accurate is GigaChords?
Automatic chord detection is difficult, especially with dense mixes, unusual harmony, fast passing chords, or noisy recordings. GigaChords is tested with real songs, keeps every chart editable, and focuses on useful results instead of pretending every detection is final.
Does GigaChords upload my music?
No. V1 analyzes local files and microphone recordings on your device. Network access is used for sign-in, subscription verification, launch updates, and feedback you explicitly choose to send; chord feedback does not include the audio file.
Which formats are supported?
Windows supports MP3 and WAV. Android supports MP3, WAV, M4A, MP4, AAC, OGG, OPUS, FLAC, and WEBM, subject to the codecs available on the device.
