Open the Import screen and upload a clear JPG, PNG, WebP or PDF chord chart. The AI detects the chord symbols and prepares a grid. You can review and correct the grid before using it.

Manual chord entry remains available and does not trigger an AI call.

After reviewing a chart, click the AI button to generate level-adapted guitar practice. The output includes editable Practice Cards with goals, first exercises, chord tones, guide tones, rhythm ideas and weekly assignments.

AI is never launched automatically. Cached identical results do not consume another credit.

Teacher Studio is the €29/month teaching plan (VAT not applicable, art. 293 B of the French General Tax Code). It lets teachers prepare, assign and track guitar practice for each student with student folders, assignments, editable Practice Cards and secure student practice links.

It is not an LMS: no student account, no messaging, no student payment, no calendar, no mobile student app and no complex dashboard.

No. A student practice link is a secure read-only page for one assignment. The student sees the work and only two buttons: I practiced and I’m stuck.

The teacher sees the latest signal in Teacher Studio. Links can be revoked and may expire.
