Platform / NanoSkool
Grace & Force
An AI that argues back \u2014 so students get the speaking practice a classroom of forty can never give them.
01 — Five modes
Practice, not a lecture about practice
World stage
Model UN
Represent a country in a live diplomacy session. Negotiate, persuade and lead against an AI delegation that pushes back.
Roleplay
Wisdom Arena
Live voice conversation with historical figures — argue as or against Gandhi, Churchill or Lincoln.
Coaching
Super Tutor
A personal AI coach for casual conversation, doubt clearing and quick quizzes.
Speech
Speech Coach
Work on vocal clarity, pacing and delivery with immediate, specific feedback.
Screening
Audio screening at scale
Record, transcribe, analyse and rank large cohorts automatically, then pass the shortlist to human review.
02 — Privacy
Audio only. No camera, ever.
The platform uses audio recording, speech-to-text transcription, voice analysis, language and content analysis, automated ranking and audio-based human review.
It does not use video, face detection, eye-contact analysis, posture analysis or any camera-based monitoring. That is a design decision rather than a roadmap gap, and it is the first thing most schools ask about — so it sits here rather than buried in a policy document.
Registration captures parent or school consent before a student records anything.
