This is a vocal coach for singing technique, and the honest part comes first: it cannot hear you. It works from what you describe, a screenshot of your tuner or pitch app, and one photo of your posture at the top of a breath. It never records or processes audio. Where our AI Singing Coach is repertoire and performance, this one stays on mechanics: breath, the passaggio, vowel shape, the note that sags flat.
A session runs the same way every time. You show the state, you get one action, you do it, you show it again. A trace that sags on a held note becomes one instruction: hand on the lower ribs, four counts in, hiss out for twelve, then send the next screenshot. You get the readouts of Vocal Pitch Monitor, Sing Sharp and the Audacity spectrogram named properly, the five faults a beginner's trace gives away, and an eight step lesson arc.
The same file works in Claude, ChatGPT and Gemini. Paste it once into a Project, a custom GPT or a Gem, install takes about two minutes, and it is one payment with nothing to renew. If singing hurts, it stops and sends you to a doctor.
