Not just a digital workbook. A learning engine designed for how children actually improve.
Most apps use fixed question banks that run out. Onzely generates unique Non-Verbal Reasoning questions algorithmically, so your child will never see the same question twice.
Our adaptive engine tracks every answer and automatically adjusts difficulty. Too easy? Questions get harder. Struggling? We slow down and reinforce.
Spaced-repetition flashcards for the high-value words that dominate GL Assessment Verbal Reasoning papers. Words appear as tooltips inside practice questions so children learn them in context.
When your child gets something wrong, AI generates a simple, encouraging explanation written for a 9-10 year old. Learning from mistakes, not just practising them.
Children earn Experience Points (XP) for every correct answer, unlock achievements, and level up from Cub to Onzely Elite. Practice feels like play.
We use AI to make practice more effective. It works within clear rules and guardrails, always in service of your child's understanding.
When your child gets something wrong, they get a clear explanation based on their specific answer. Not a generic hint. A response to what they actually did.
Every maths question has a scratchpad for working. Children can see exactly where their reasoning went wrong, not just that the final answer was incorrect.
AI generates questions that follow precise rules and content guardrails, keeping every question accurate, age-appropriate and matched to real exam formats. Your child never runs out of fresh practice.
All four subjects, fully covered. For grammar schools and independent school entry.
✦ Algorithmically generated, unique every time

Children earn 10 Experience Points (XP) for every correct answer, unlock achievements like Week Warrior and Century Club, and level up from Cub all the way to Onzely Elite.
