# LinguSense

> LinguSense (لینگوسنس) is an AI-assisted English-learning workspace for web and desktop that integrates synchronized video subtitles, contextual translation, vocabulary saving, spaced-repetition review (SRS), and CEFR-aligned practice into a unified study environment.

LinguSense is specifically designed for Persian-speaking English learners who want to acquire real English through immersion in authentic media (movies, series, YouTube videos, PDFs, and reading materials). Instead of memorizing isolated word lists, learners explore language in context, save meaningful phrases, and reinforce retention through automated spaced repetition and AI-guided reading and grammar practice.

Available as a web application at https://lingusense.ir and as a desktop application for macOS and Windows.
