LingoSub

LingoSub provides a tool for language learners to watch real videos with dual subtitles, enabling word-by-word understanding and saving vocabulary. It presents videos chosen to match a learner’s level after a short assessment, and supports viewing with translations and notes embedded in context. The approach centers on following along with native content to build comprehension and recall. The service emphasizes a self-paced, interactive experience rather than graded lessons.

LingoSub measures a user's level with a short, three‑minute test that estimates vocabulary knowledge and placement from A1 to C2. It then selects videos where most words are already understood, enabling a pace that learners can keep up with. The system presents translations above each word initially and adjusts as proficiency grows. It uses real videos from native creators and keeps the interface focused on clarity and comprehension.

LingoSub highlights word-by-word translations, dictionary forms, grammar notes, and sentence-level context for each term. It supports adjustable playback speed and line-by-line replay to accommodate different learning speeds. The platform offers videos across scripts and registers, including vlogs, comedy, music, and lessons, with level ratings to help users pick suitable content.

LingoSub outlines its available languages and video catalog on the docs page, and describes plans and a separate Pro offering. It indicates a free experience with optional paid features and mentions a Pro tier with additional capabilities. It emphasizes accessibility without mandatory sign-up for core watching and testing, while noting paid features for enhanced translation and word notes.
