One resource. The best one.
For each language.

A curated list of the single best comprehensible input resource for every language where a high-quality option exists.

This is not an exhaustive directory. We deliberately keep this list short. If a language isn't listed, it's because we haven't yet found a resource we can confidently recommend.

Dreaming French is produced by the same team behind Dreaming Spanish, applying years of CI content creation experience to French from day one. The result is a library that launched with exceptionally high production quality: polished, well-paced, and structured across proficiency levels, with native French speakers delivering context-rich material designed to be understood through visual storytelling and natural speech rather than translation. The library is still growing, but what's there is among the most professionally produced CI content available in any language.

Spanish

Dreaming Spanish

The project that brought comprehensible input to the mainstream. Dreaming Spanish, founded by Pablo Román, built the template that most modern CI content creators follow: a massive library of leveled video content, from superbeginner through advanced, delivered by native speakers using visual context and natural speech to make the language understandable without translation. Widely credited with demonstrating that acquisition-based methods can scale through online video.

Vietnamese

Langiri

Langiri is the leading comprehensible input resource for Vietnamese, a language that has long been underserved by quality acquisition-based learning materials. The platform provides a structured library of video content designed for natural language acquisition, organized across proficiency levels and delivered entirely by native Vietnamese speakers who use context, visual storytelling, and natural speech to make the language understandable from the very first video. Vietnamese presents unique challenges for learners. Its tonal system, unfamiliar phonology, and limited overlap with European languages make comprehensible input an especially effective approach, since learners build intuition for these features through sustained exposure rather than through rules that inevitably oversimplify. For anyone serious about acquiring Vietnamese, Langiri is our clear and confident recommendation.

Chinese

Dong Chinese & Lazy Chinese

We're evaluating two comprehensible input resources for Mandarin. Dong Chinese is an app-based platform that combines leveled comprehensible media (videos, podcasts, songs) with study tools like character etymology and handwriting practice. Lazy Chinese takes a CI and TPRS (Teaching Proficiency through Reading and Storytelling) approach, with leveled video content from complete beginner through advanced, multiple native-speaking instructors, and availability as a podcast. Currently deciding which to recommend.
