  description

  ThreadIn helps non-native English speakers understand real online comments and learn English from the conversations they already read.
  
  It works inside supported websites and adds lightweight learning tools directly to comment sections. You can translate comments, understand hidden meaning, learn useful words and slang, save vocabulary, and draft natural replies with your own AI API key.
  
  Main features:
  
  • Translate comments and post content
  • Explain slang, memes, tone, and cultural context
  • Show the hidden meaning behind a comment
  • Extract useful words and internet expressions
  • Save words and review them later
  • Highlight saved words when they appear again
  • Translate selected text on the page
  • Generate natural English replies based on the comment context
  • Translate video subtitles
  • Export your vocabulary and learning records
  • Use your own OpenRouter API key
  
  ThreadIn is designed for people who want to read English comments more easily, understand native-like expressions, and join online conversations with more confidence.
  
  Your API key stays in your browser storage. ThreadIn only sends the text needed for translation, explanation, vocabulary extraction, subtitle translation, or reply generation to the AI provider you configure.

  ThreadIn helps you understand what people really mean online.
  
  Real conversations are full of slang, acronyms, memes, sarcasm, tone, cultural references, and community shorthand. ThreadIn brings an internet context layer to the pages you already read, so you can follow comments, posts, threads, articles, lists, and subtitles without constantly searching what things mean.
  
  It is not just a translator. ThreadIn explains the meaning behind the words, helps you learn useful expressions from real content, and gives you natural reply suggestions when you want to join the conversation.
  
  Main features:
  
  • Translate comments, posts, selected text, and subtitles
  • Explain slang, acronyms, memes, jokes, tone, sarcasm, and cultural context
  • Reveal hidden meaning, subtext, and community shorthand
  • Understand real conversations across websites with comment sections
  • Extract useful vocabulary and internet expressions from content you read
  • Save words, phrases, and examples for later review
  • Highlight saved words when they appear again
  • Generate natural replies based on the thread and context
  • Translate video subtitles
  • Export your vocabulary and learning records
  • Use your own OpenRouter API key
  
  ThreadIn is built for language learners, English speakers, and anyone who feels out of the loop online. Whether you are reading in another language or just trying to understand fast-moving internet culture, ThreadIn helps you read faster, understand deeper, and reply more naturally.
  
  Privacy & data usage:
  
  ThreadIn only activates when you explicitly use it, such as clicking the extension, selecting text, or choosing a feature. It does not run automatically on pages, monitor your browsing activity, or collect your browsing history.
  
  Your data stays in your browser by default. Saved vocabulary, learning records, and settings are stored locally.
  
  When you use AI-powered features, only the text needed for that request is sent to the AI provider you configure, such as through your own OpenRouter API key.
