Contact

One email for everything

Clef is built and supported by one person. Whether it's a support question, a bug, feedback, or a press inquiry, write to [email protected] — your message lands directly with the founder, not a ticket queue. You'll usually hear back within one to two business days.

Reporting a bug

The more of this you can include, the faster it gets fixed:

  • Your browser and version (for example, Chrome 126).
  • Your keyboard or digital piano model and how it's connected.
  • The piece you were practicing and what you were doing when it happened.
  • What you expected, and what happened instead.
