Built around The Urban Historian’s teaching materials
LEXA comes from the founder of The Urban Historian, a Singapore O-Level History and Social Studies specialist.
When your child submits an answer, LEXA marks it against the notes, rubrics and worked examples used in The Urban Historian’s lessons, so the guidance matches how the subject is actually taught.

Questions parents ask
Which levels are included?
Secondary 1 to 4 History. One subscription covers every level currently available.
Does LEXA replace a teacher?
No. Feedback is AI-generated and is designed to support practice between lessons, not to replace a teacher.
Does it give answers before the student attempts the question?
No. Ask Lexa explains what a question is asking and suggests how to begin. A suggested answer appears only after your child submits their own attempt.
Can students make corrections?
Yes. After feedback, your child can open My Corrections and write an improved answer. The original submission stays locked, and corrections are not given a new score.
What devices work best?
A laptop or desktop. Tablets work, though long written answers are easier with a keyboard. Phones are not recommended for worksheet practice.
