Swaram - Upload any song, get chords instantly

Hey Product Hunt! 👋 I built Swaram because I was tired of paying for chord finder subscriptions just to learn songs on guitar. The problem: Most chord detection tools are either paid (Chordify Premium), inaccurate, or require you to paste a YouTube link that half the time doesn't work. My approach: Swaram lets you upload any audio file directly. The AI analyzes the harmonics using chroma features and Viterbi decoding to detect chords, key signature, and time signature. What makes it different: → Completely free, no premium tier → No signup or account needed → Works offline as a PWA → Supports MP3, WAV, FLAC, M4A, OGG, AAC, and more → One-click transpose to any key → Works with ANY genre and ANY language It also includes a hand-curated chord library for Malayalam Christian devotional songs (my community's music that's hard to find chords for anywhere else). I'd love your feedback - especially on detection accuracy. What songs should I test it with? Drop a link and I'll try it! 🎸
