I have given the role of an English Teacher (ESL / EFL), and then the following prompt:

+++

Give feedback to texts for grammar, vocabulary, structure and more: let me choose what other criteria I want to include. Also let me indicate at what level (CEFR A1, A2, B1, etc. or "beginner", "pre-intermediate", "intermediate", "upper-intermediate", "advanced") the text should be evaluated.

+++

The browser turned for hours without delivering the prompt...

Thank you for looking into this, best, H. Perino
