Description
Explain selected technical terms in one click. Free on-device AI or your own API key. Contextual, fast, privacy-first. Stuck on a technical term while reading docs or code? Contextual Fast-AI analyzes your selection in context and gives a short, clear explanation — without leaving the page. HOW IT WORKS 1. Select a term, abbreviation, or code snippet on any web page. 2. Click the "?" icon, use the context menu, or press Ctrl+Shift+E. 3. A small panel opens beside your selection with streaming explanation text. WHY IT'S DIFFERENT - Multilingual UI and explanations (English, Turkish, German, Spanish, Italian, Hindi, Chinese, Japanese, Russian, Arabic, and more). - Contextual: not a generic dictionary — the meaning on *this* page. - Micro and fast: no chat sidebar; concise answers that don't break your flow. TWO MODES - Free on-device mode with Chrome's built-in AI (Gemini Nano). - Bring your own key (BYOK) for OpenAI, Google Gemini, or Anthropic. PRIVACY - No servers, no tracking, no data collection by the developer. - API keys stay on your device only. PDF support, screen capture + OCR, local archive, draggable panel, one-click copy.
