AI Reading Assistant – Chrome Extension

A Chrome extension that allows users to highlight text on any webpage and send it to an LLM for summarizing, paraphrasing, explaining, or translating via OpenRouter.

---

Features

• Highlight text and trigger AI actions using the right-click context menu or keyboard shortcuts
• Supported actions:
  • Summarize
  • Paraphrase
  • Explain
  • Translate (to Spanish)
• LLM responses are displayed in a floating box injected into the page
• Commands are configurable via the manifest and routed through a modular provider system (currently OpenRouter)

---

Architecture

• UI is currently handled directly in content/content.js
  • A result box is created using document.createElement
  • Styles are applied inline via JavaScript
• The ui/ folder exists but is not yet used
• The LLM provider logic is modular, configured in llm/
• The background/ folder registers context menus and shortcuts and forwards commands
• The commands.js module maps actions to instructions and calls the LLM
• The llm/router.js file routes to the correct provider (OpenRouter)
• Provider setup uses llm/secrets.js and llm/config.js to handle keys and defaults
