Hey Product Hunt! 👋
I’m Amit, creator of FlexChords.
As a guitarist, I was constantly frustrated by two things:
1. Trying to learn a song on YouTube, only to find chord charts in the wrong key or horribly oversimplified.
2. Existing chord-detection platforms locking basic play-along tools, tempo control, and transposing behind rigid subscriptions.
I built FlexChords to make learning and jamming along to any song effortless, accurate, and interactive. It is still a work in progress, and I'm continuously adding new features as well as refining the chord prediction pipeline.
🎸 What makes it stand out?
- No Hallucinated Chords: Raw ML chord models tend to produce erratic, rapid-fire jitter. FlexChords uses a custom deterministic music-theory smoothing layer that absorbs glitches and respects key context for clean, playable progressions.
- YouTube & Audio Uploads: Paste any YouTube link or drop an audio file to extract synchronized chords aligned with the track.
- Interactive Timeline Editor: Tweak a chord voicing, adjust boundaries, or split sections directly on the visual timeline with full undo/redo. (MIDI export coming soon!)
- Musician-First Tools: Automatic Key & BPM detection and Audacity label export.
- Start Playing Instantly: Unlimited access to all pre-analyzed catalog songs, plus 5 free custom song analyses for every user (resets every month).
