Using the AI sidebar extension allows you to easily summarize the text of web pages using ChatGPT(and Gemini). When you want to summarize a web page, simply open the page and click the **“Capture”** button in the **AI Sidebar**. The page’s main text is extracted and automatically pasted into the input box of your chosen AI engine—**ChatGPT or Gemini**—ready to be used as a summarization prompt. You can also capture YouTube subtitles and feed them to either engine in exactly the same way.

### Key Features
* 🤖 **AI-Engine Integration** Launch ChatGPT or Gemini directly from the browser sidebar—no tab switching, instant access to powerful conversational AI.
* 📝 **Text Capture** Automatically scrapes the visible article content and drops it straight into the selected AI’s message box—no manual copy-and-paste required.
* 📋 **Prompt Templates** Inserts a preset template optimized for both engines, so summarizing web content becomes a one-click operation.
* 🎥 **YouTube Subtitle Ingestion** Seamlessly pulls transcript data from YouTube videos and pastes it into the AI prompt field, making long-form videos quick to digest.
* ✂️ **Intelligent Splitting** If the captured text exceeds a configured length, it’s automatically chunked and sent to the AI in sequence—keeping even very long documents flowing smoothly.
