Prototype course software

For authorized course use

Icerynk is a prototype AI learning system developed by Prof. Christian Grewell for students enrolled in his courses. It is experimental and is not an official NYU service or system of record.

Authorized course work only. Do not share access or submit sensitive, confidential, client, proprietary, or FERPA-protected information; some activities use third-party AI services.
Some activities use secure local models, with zero data retention.
AI output can be wrong. Verify it. You remain responsible for your work, attribution, decisions, and compliance with course and NYU policies.
