About CheckMyMic

CheckMyMic is a set of browser-based device testers built for one moment: when something isn't working and you need to know right now — the call that starts in five minutes, the interview, the stream about to go live.

Our promise

Nothing leaves your device. Your microphone and camera are accessed only to run the test in your browser. We don't record, upload, or store your audio or video. We collect nothing that identifies you. See the privacy policy for the details.

How it works

The browser itself can do what a chatbot never could: read your microphone in real time with the Web Audio API, measure the signal, and tell you plainly whether it's working — or exactly what to fix. One click, no account.

What's next

The microphone test is live. Webcam, keyboard, mouse, speaker, dead-pixel and controller testers are on the way — each built to the same bar: instant, private, and genuinely helpful.
