PitchCraft (Pitch Craft) turns your phone into a real-time vocal coach. Sing into the mic and watch your pitch drawn live on a piano-roll graph — see exactly when you're sharp, flat, or right on the note.

WHAT YOU CAN DO
• Real-time pitch detection — your voice plotted note by note as you sing
• Piano-roll pitch graph with note names and a scrolling timeline
• Vocal exercises, scales and key selection for deliberate practice
• Reference track — load a song and sing along, with A/B comparison
• Record & Play — capture your take and add your own voice as a channel
• Vocal report after every take: intonation accuracy, sharp/flat bias, vibrato rate and depth
• Microphone & headphone setup with latency calibration (great for Bluetooth)

NEW: SING TO CHORDS
• A piano with bass plays a chord progression under your voice — pop I–V–vi–IV, the '50s progression, three-chord songs, jazz ii–V–I, 12-bar blues and minor progressions — in your key and tempo
• Six exercises: find the chord tone (root, third or fifth), arpeggio over the progression, held note while the chords change, voice leading to the nearest chord tone, landing on a target tone at each change, and free improvisation
• The graph highlights the tones of the chord that is sounding, so you see where there is room to sing
• Harmonic report: how much time you sang chord tones, colour tones, scale tones or outside the harmony, your tuning against the nearest chord tone, and the chord or tone that went worst
• Works on your own separated songs too: mute the vocal and sing your own line over the real track

AI STEM SEPARATION (free during the pilot)
• Upload a song and let AI split it into separate stems — vocals, drums, bass and the rest
• Choose 4 stems, or 6 stems that also isolate guitar and piano
• Mixer: control volume, mute and solo each stem independently
• Transpose the whole song into your vocal range — chord names follow along
• Karaoke lyrics: automatically transcribed, time-synced words scroll right on the pitch graph
• Chords, key & tempo: optional detection draws a chord ribbon above the graph and shows key, BPM, current and next chord
• Download your own mix as WAV: instrumental, karaoke version, or your cover with your voice on top
• Download the stems as a zip, or drag them back in to reload instantly
• Sign in with Google to use separation free during the pilot (a small daily limit keeps it fair)

PRIVATE BY DESIGN
Real-time pitch detection runs entirely on your device — your live singing never leaves your phone. For AI stem separation, the song is sent to our server, processed, and the original is deleted immediately; the result is streamed to you once and then removed. We keep no copies. See our privacy policy for details.

Perfect for singers, music students, choir members, karaoke lovers and anyone training their ear. No ads. Free to start, no account needed for the basics.
