Lingvist

Lingvist is an Estonian education technology company building an AI-powered language-learning platform that uses machine learning, language statistics and spaced repetition to teach the vocabulary a learner actually needs. It was founded by Mait Müntel, a physicist who worked on the Higgs boson discovery team at CERN and built the first prototype to teach himself French. Lingvist maps each learner's knowledge in real time and adapts course material to them individually, offering 60+ courses across 15+ languages, a Custom Decks feature that turns a learner's own words or texts into a course, and a Lingvist for Business offering. Lingvist does not operate a public, self-serve API program - no developer portal, API reference or machine-readable specification is published. It does run an OAuth 2.0 protected API at api.lingvist.com whose endpoints are publicly documented only through Lingvist's own open-source NodeBB single-sign-on plugin, with client credentials arranged directly with Lingvist rather than self-registered.

Lingvist publishes 1 API on the APIs.io network. Tagged areas include Company, Education, Language Learning, EdTech, and Artificial Intelligence.

Lingvist’s developer surface includes documentation, support, engineering blog, pricing, signup flow, authentication, and 15 more developer resources.
