What does Side Reader do?
Side Reader is a Chrome extension that solves a specific but common problem: reading PDF documents while using AI chat interfaces like ChatGPT, Claude, and DeepSeek. Instead of constantly switching tabs or copy-pasting content, you can open PDFs directly in the sidebar of these AI platforms. This allows for seamless interaction with your documents - you can ask the AI to summarize sections, translate content, explain complex concepts, or answer specific questions about the material.
The tool offers practical features like PDF zooming, page navigation, and width adjustment for comfortable reading. What sets it apart is its screenshot functionality for areas with non-selectable text and customizable interaction buttons that let you tailor how the AI responds to your PDF content. Importantly, Side Reader stores all files locally in your browser, ensuring your documents remain private and secure.
This extension is particularly valuable for students analyzing research papers, professionals reviewing contracts or reports, and researchers working with academic literature. It transforms how you interact with PDFs in AI environments, making document analysis more fluid and integrated rather than a separate, cumbersome process.
