About this tool

Real voice cloning — copying a specific human's voice — requires server models and, ethically, that person's consent; we won't ship a consent-less clone button. What this demo does is teach the real skill underneath: voice-profile design. Pick a base engine voice, tune pitch, rate and warmth, audition any script, and save the profile as a shareable JSON string. It's how TTS directors actually work, minus the legal minefield. Your file never leaves this page — processing runs in your browser via WebAssembly; nothing is uploaded and the file is dropped from memory when you close the tab.
