01 Problem

Learners on the DepEd MATATAG curriculum often share a phone and have no reliable internet, so cloud-based edtech never reaches them.

02 What I built

Mastery-gated practice generated from teachers’ own MATATAG lessons, the on-device llama.cpp tutor running SeaLLMs-v3 1.5B, and teacher-to-learner sync over a phone hotspot. 659 tests.

03 Security notes

Everything runs on the device. No learner data leaves the phone, and the AI never grades.

04 Impact

Shows that a useful AI tutor can run fully offline on the kind of shared phone a public-school family actually owns. Teachers don’t have to write anything new; their existing lessons become the practice.
