Optional tutor critique

The tutor sends the previewed material to Groq’s Qwen 3.8 27B model through this application. It is fallible and does not assign mastery. Groq may retain or process data under its applicable policies. Authored hints remain available if it is unconfigured. Your claim, mechanism, unknown, next experiment and hint count are sent only after consent and clicking Request.
