Frequently Asked Questions
Real-time vocal pitch trainer with free AI stem separation.
Is PitchCraft free?
Yes. Real-time pitch detection, the piano-roll graph, vocal exercises, and recording are free with no account needed. AI stem separation (splitting a song into vocals, drums, bass, and other) is free during the current pilot for users who sign in with Google, with a daily usage limit.
What makes PitchCraft different from other vocal trainer apps?
PitchCraft runs pitch detection entirely on-device in real time — your voice never leaves your phone for the core feature. It combines a piano-roll pitch graph, reference-track singalong with A/B comparison, and AI-powered song stem separation with auto-transcribed karaoke lyrics in a single free app, with no ads.
Does PitchCraft work in a browser or do I need to install an app?
Both. PitchCraft is a web app at pitchcraft.thapps.dev that works directly in any mobile or desktop browser, and is also available as a free Android app on Google Play (search "PitchCraft - Vocal Trainer").
Can I sing along to a real song and see my pitch accuracy?
Yes — load a reference track, sing along, and PitchCraft shows an A/B comparison of your pitch against the original on the same piano-roll graph.
What is AI stem separation and how does it work in PitchCraft?
Upload a song and PitchCraft's AI splits it into separate stems (vocals, drums, bass, other) that you can mix, mute, or solo independently — useful for practicing over an instrumental or isolating a vocal line to study. Karaoke-style lyrics are auto-transcribed and time-synced to scroll alongside the pitch graph. Stems can be downloaded as a zip.
Is my data private?
Yes. Real-time pitch detection never sends audio anywhere — it's fully on-device. For AI stem separation, the uploaded song is processed on PitchCraft's server and deleted immediately after; no copies are kept.
Who is PitchCraft for?
Singers, music students, choir members, karaoke enthusiasts, and anyone training their ear or pitch accuracy — from complete beginners to people preparing performances.
