About This Tool

Sider (formerly ChatGPT Sidebar) is a powerful browser extension that brings multiple AI models into a convenient sidebar. Instead of constantly switching tabs to copy-paste text into ChatGPT, Sider lives alongside your workflow. You can highlight text on any website to summarize it, explain complex concepts, or translate it instantly.

How to Use

  1. 1. Install the Sider extension for Chrome or Edge.
  2. 2. Open the sidebar by clicking the icon or using a shortcut (Cmd/Ctrl + P).
  3. 3. Select your preferred model (GPT-4, Claude 3, Gemini).
  4. 4. Chat normally or highlight text on a webpage to trigger the context menu.
  5. 5. Use the “Chat with PDF” or “Chat with Image” features for specific files.

Use Cases

Sider is essential for researchers, students, and writers who browse the web extensively. It allows users to summarize long articles in seconds, draft emails directly inside Gmail, or translate foreign language pages without leaving the site.

Model Variety

One of Sider’s biggest strengths is its neutrality. It doesn’t lock you into one AI provider. You can toggle between ChatGPT (OpenAI), Claude (Anthropic), and Gemini (Google) depending on which model handles your specific task best.

Vision & PDF

Sider includes OCR (Optical Character Recognition) capabilities. You can take a screenshot of a chart or error message, and Sider will analyze it. It also has a built-in PDF reader that lets you chat with documents to extract key information.

Limitations

As a browser extension, it functions within the web environment. While it has a mobile app, the core powerful experience is desktop-centric. Access to premium models like GPT-4 often requires a paid subscription due to API costs.

YouTube Summaries

A popular feature is the ability to summarize YouTube videos. When watching a video, a “Summarize” button appears, generating a concise breakdown of the video’s transcript with timestamps, saving hours of watching time.
