  Courier Web — Connect Your Browser to AI Workflows
  
  Courier Web is a productivity extension that connects everyday browsing with modern AI assistants. It allows you to capture information from any webpage and instantly send it to tools like ChatGPT, Claude, Gemini, DeepSeek, and other platforms without interrupting your workflow.
  
  Instead of manually copying content between tabs, Courier Web lets you work with AI directly from the page you are already on.
  
  Highlight content, capture visuals, collect video transcripts, or use the built-in side panel — and send information to AI in seconds.
  
  
  BUILT FOR HOW PEOPLE ACTUALLY USE AI
  
  Many users rely on AI throughout the day but still follow a repetitive process:
  
  • copy information
  • open an AI website
  • paste content
  • rewrite prompts
  
  Courier Web removes these extra steps by creating a direct connection between web content and AI tools. The result is a faster, more focused workflow that keeps attention on the task instead of tab switching.
  
  
  CORE FEATURES
  
  HIGHLIGHT TEXT AND ANALYZE INSTANTLY
  
  Select text from articles, documentation, research papers, emails, or web applications and send it directly to your preferred AI assistant for summarization, explanation, rewriting, or deeper analysis.
  
  This workflow is ideal for research, learning, writing, and professional productivity.
  
  
  SIDE PANEL FOR PERSISTENT ACCESS
  
  Courier Web includes a built-in side panel that keeps your AI workflow accessible without leaving your current page.
  
  Open it with the toolbar icon or keyboard shortcut (Cmd+Shift+K on Mac / Ctrl+Shift+K on Windows) and access your destinations, templates, and capture tools alongside any webpage — no tab switching required.
  
  The side panel stays out of the way until you need it, making it ideal for ongoing research sessions, long reading tasks, or any workflow where you return to AI repeatedly.
  
  
  YOUTUBE TRANSCRIPT CAPTURE AND VIDEO LEARNING TOOLS
  
  Courier Web integrates with YouTube to automatically collect video transcripts when available.
  
  Users can quickly turn long videos into structured information by sending transcripts to AI for:
  
  • summaries and key takeaways
  • study notes and learning guides
  • lesson preparation
  • research extraction
  • documentation review
  
  This feature helps transform video content into usable knowledge without manual copying.
  
  
  SCREENSHOT AND VISUAL CONTEXT CAPTURE
  
  Capture a selected area of any webpage and send it to AI for interpretation.
  
  Use the toolbar button or keyboard shortcut (Cmd+Shift+U on Mac / Ctrl+Shift+U on Windows) to capture a region instantly.
  
  Common uses include reviewing interface designs, explaining code shown on screen, analyzing visual information, or generating feedback from images and layouts.
  
  
  REUSABLE PROMPTS AND WORKFLOW TEMPLATES
  
  Courier Web supports reusable prompts so common tasks can be completed consistently.
  
  Users can build workflows for summarizing information, rewriting content, extracting action items, brainstorming ideas, or organizing research materials.
  
  Templates reduce repetitive work and help standardize AI usage across daily tasks.
  
  
  FLEXIBLE AI DESTINATION SUPPORT
  
  Courier Web works alongside multiple AI tools and web destinations, allowing users to maintain a consistent workflow regardless of which AI assistant they prefer.
  
  The extension focuses on connecting existing tools rather than replacing them.
  
  
  PERFORMANCE AND PRIVACY FOCUSED DESIGN
  
  Courier Web is designed with modern Chrome extension standards in mind.
  
  • lightweight architecture
  • minimal permissions
  • no unnecessary background activity
  • runs locally until you initiate an action
  
  Users remain in control of what information is shared and when.
  
  
  WHO USES COURIER WEB
  
  • students organizing study material
  • educators preparing learning resources
  • professionals conducting research
  • developers reviewing technical documentation
  • writers improving drafts and communication
  • creators transforming online content into structured outputs
  
  Anyone who regularly combines browsing with AI assistance can benefit from a streamlined workflow.
  
  
  EVERYDAY USE CASES
  
  Courier Web helps users:
  
  • summarize long articles quickly
  • convert YouTube videos into notes
  • analyze screenshots or visual content
  • rewrite emails and documents
  • extract key insights from research
  • access AI tools instantly via the side panel without losing your place
  • organize information without switching tabs
  
  The extension reduces friction between discovering information online and working with AI.
  
  
  WHY COURIER WEB IS DIFFERENT
  
  Many AI extensions add interfaces that interrupt your browsing. Courier Web's side panel is designed to complement your workflow — staying out of the way until you need it.
  
  Courier Web focuses on workflow integration. It brings AI directly into the browsing experience so users can interact with information naturally, without changing how they already work online.
