Toko
Toko is an AI-powered English speaking tutor that lets learners hold short, realistic conversations with an AI and get instant feedback on grammar and pronunciation. Founded in 2021 by MIT engineers Jen Liu and Erica Du and backed by Y Combinator (W22), the New York-based app is especially popular across East Asia, with more than 1 million downloads and tens of thousands of five-star reviews.
Jennifer Liu
Jennifer Liu is the cofounder and CEO of Toko, an AI English tutor that got its start when a pandemic-era hack called GPT 奶奶 (an AI grandma built to help her practice Mandarin) revealed a far bigger hunger for spoken English across East Asia. An MIT computer science grad and early Quizlet engineer-turned-PM, Liu turned that side project into a Y Combinator (W22) company that now ranks among the top education apps in Taiwan, Hong Kong, Vietnam and Thailand, with 4.9 stars from 20,000-plus reviewers.
