Pitch 1024 A universal MCP app · by Chardonn.AI

Find your pitch — in a friend's voice.

A pocket pitch pipe inside your AI chat — reference notes, starting pitches for any key, and ear-training, each one sung by a real person. Tap the clock-face and hear it. Works in ChatGPT and Claude.

Pitch 1024 is also a standalone iOS / Android app — this brings the same pitch pipe into ChatGPT and Claude.
