Free tools for singers & creators
Genuinely free, genuinely private. Every tool here runs inside your browser on your own device — no account, no install, and your audio is never sent anywhere.
Why these are free
Finding your vocal range should not require an account or an upload when the browser can measure it locally. The range finder uses the tested in-browser detector behind this demo; the desktop performance engine is separate and has its own release tests.
