Preply

Preply is a global online language-learning marketplace that connects learners with private tutors across dozens of languages, offering one-on-one video lessons, flexible scheduling and a satisfaction-backed tutor-replacement guarantee. Alongside its consumer marketplace, Preply runs Preply Business, an enterprise language-training offering with SSO, automated user provisioning and LMS integrations. Preply exposes a small public, unauthenticated tutor-search API (originally published as an OpenAI/ChatGPT plugin) that lets applications and agents search tutors by subject, price, availability and language and fetch individual tutor profiles. This profile was enriched by the API Evangelist pipeline from Preply's public surface.

Preply publishes 1 API on the APIs.io network: Chatgpt Openapi API. Tagged areas include Company, Education, Language Learning, Tutoring, and Marketplace.

Preply’s developer surface includes engineering blog, support, and 14 more developer resources.
