A more honest handoff

Useful evidence, clear boundaries.

01

Analysis stays local

Both full mixes are decoded and compared in your browser. Audio, filenames, source hashes, and lyrics are never uploaded.

02

Evidence before interpretation

A deterministic comparison reports bounded signal-shape differences before intent or generation context is applied.

03

You choose the AI

Copy a provider-neutral handoff that states its limits clearly. You decide whether to share it and where it goes.
