Building a custom math tutor powered by ChatGPT

Summary

OpenAI feature story from February 2025 about a parent who built a custom GPT acting as a math tutor for their child — using the custom GPT builder to create a patient, Socratic math tutoring experience tailored to their child’s level and learning style. Published alongside the halibut fishing story as a pair of “real people using AI for real things” human-interest pieces.

Implications

Custom GPTs as a low-code product platform. The math tutor story demonstrates custom GPTs as an accessible tool for non-developers — a parent building an educational tool without writing code. The value is in the personalization (calibrated to the specific child) and the patience (AI that never gets frustrated), both difficult to achieve with human tutors at scale.

Education AI at the family level. The narrative positions ChatGPT not as a school system tool but as a family resource — a parent independently building educational support for their child. This is a different adoption vector from the institutional education partnerships (AFT, OpenAI for Education). Both matter; the family-level adoption is harder to measure but potentially wider.

Companion to the Praktika story. Praktika (language learning) and the math tutor (custom GPT for education) represent different models for AI-powered learning: a purpose-built product vs. a general tool customized for a specific use. Both have merit; they serve different user needs and technical comfort levels.

Watch: Whether custom GPT usage for education drives retention and upgraded subscription among parent demographics, and whether OpenAI surfaces educational custom GPTs in a dedicated discovery mechanism.
