Pearson deployed Smart Lesson Generator, an AI tool for English language teachers that produces curriculum-aligned lesson activities in seconds based on the teacher's chosen topic, vocabulary, and proficiency level. As of April 2025, over 4,000 educators worldwide had access to the tool.

Launched in April 2025, Smart Lesson Generator accepts a teacher's selection of activity type (e.g., vocabulary exercise, grammar task, reading comprehension), topic, and language proficiency level as inputs, then uses a large language model to generate a draft activity. All generated content is filtered through Pearson's Global Scale of English (GSE) — a proficiency framework from 10 to 90 — to ensure level-appropriateness before delivery. The tool works with Pearson courseware and with non-Pearson materials. A Pearson study found that 76% of teachers spend at least one hour of personal time per week on lesson planning.
