The lyrics follow your voice. You just sing.

Sufler X is a prompter for singers and an assistant for vocal teachers. On stage the words move with you; at home you rehearse with your backing track; in class the student sees the lyrics on their phone while the teacher runs the track, the key and the schedule.

The app is being translated: the English interface arrives first for performers, then for teachers.
For performers

A prompter that listens

Starts with your voice

Begin singing — the lyrics start from the first line. No pedal, no helper at the side of the stage.

Keeps your tempo

The text follows the marks from your rehearsal; if the band plays faster or slower, your voice puts it right.

One touch to recover

Lost your place? Double-tap the line you are singing — the prompter continues from there. Works without internet.

Rehearse at home

The backing track plays on your computer, the lyrics run on your phone — and the phone marks every line for the stage by itself.

For vocal teachers

Everything for the lesson in one place

In class

  • Backing track with the key changed in one tap — the tempo stays
  • The student sees the lyrics on their own phone, line by line
  • Fragments, loops and takes recorded from the remote
  • Send the track to the student to practise at home

Around the lesson

  • Students, schedule and paid lessons — also on your phone
  • Balance of lessons for each student, reminders to pay
  • Your data lives on your USB stick, encrypted with your PIN
  • Works in the browser on any computer — nothing to install
For vocal schools

One account for the whole school

The head invites teachers and an administrator; the administrator schedules lessons for everyone; each teacher works from their own USB stick. Rooms with QR plates, the school's logo, weekly reports.
