Why SIBOL

Good help shouldn't depend on good signal

Lots of kids in the Philippines study where the internet is slow, costly or gone. That's exactly where they need help the most.

Offline first

Lessons, practice and explanations live on the phone. No signal? Class continues.

Speaks their language

English, Tagalog and Taglish everywhere, with answers Gabo can read out loud.

Private by design

No sign-ups. A child's progress stays on their device, and questions go to a model in the room.

How it works

Ask, think, learn. Easy lang!

Where the answers come from
Three learning modes

One tutor. Three ways to learn.

Every child learns differently. Three modes, designed with learners with disabilities and learning differences in mind. Each one changes how the app looks and how the AI talks.

Kalma

Calm and focused
Designed with these learners in mind
ADHDAutismSensory sensitivity

A quiet space with fewer distractions, for learners who do best when things stay simple and predictable.

The screen

  • Plain background, no music
  • One question at a time
  • Same layout every time

The AI

  • Two short sentences, max
  • One idea per reply
  • Calm, gentle tone

Each mode's rules are enforced in code, so a small model can't wander off. Any learner can pick any mode. SIBOL supports different learning needs; it does not diagnose or treat any condition.
