About the founder
Founder & Lead Educator
Rachel Esco is an Ontario Certified Teacher, copywriter and AI evaluator. She brings all three careers to one mission: closing the gaps AI has opened in modern education by strengthening core literacy and critical thinking, so students trust their own judgment and express their ideas with confidence.
Rachel studied English, with a focus on Shakespeare, creative writing and critical thinking, and earned her Bachelor of Education at York University. While teaching high-school English with the York Region District School Board, she founded Thornhill English Tutor, her own private practice offering one-on-one sessions. That practice has since grown into a virtual English learning lab.
Alongside teaching, she spent more than a decade as a creative copywriter, where a single clumsy word can sink a campaign. That work trained her eye for subtleties few educators get the chance to study: how sentence structure and syntax shape clarity and meaning, and why certain words feel just right.
In 2022 she was recruited to an AI research lab to work alongside a select team of specialists: teachers, licensed professionals such as doctors and lawyers, and academics. Together they designed highly complex tests to expose weaknesses in AI reasoning, knowledge and writing, then wrote detailed reports that helped improve the intelligence of AI models, including models owned by OpenAI and Apple.
