What is Side Reader?
Side Reader is a powerful Chrome extension that revolutionizes how you interact with PDFs while using AI chatbots like ChatGPT, Claude, and DeepSeek. It seamlessly integrates a PDF reader and chat interface into the sidebar of these platforms, allowing you to read documents and ask questions about them without switching tabs. With Side Reader, you can upload any PDF and instantly start a conversation with the AI about its contents. This means you can summarize lengthy reports, extract key data, clarify complex concepts, or even get step-by-step explanations from textbooks—all within the same window where you're already working.
The extension is designed for students, researchers, professionals, and anyone who frequently works with PDFs. Imagine studying a research paper on ChatGPT: you can highlight a paragraph and ask the AI to explain it in simpler terms, or ask for a summary of the entire document. For business users, Side Reader enables quick analysis of contracts, financial reports, or market research without leaving your AI assistant. It also supports multiple PDFs, so you can switch between documents effortlessly.
Technically, Side Reader uses advanced PDF parsing to extract text and maintain formatting, ensuring accurate responses. It works with any PDF, including scanned documents (via OCR) and complex layouts. The chat interface remembers context, so you can have multi-turn conversations about the same document. Privacy is a priority: your PDFs are processed locally or through encrypted connections, and no data is stored on external servers.
Side Reader offers a free tier with basic features, such as limited PDF uploads and chat messages. For power users, a lifetime plan provides unlimited uploads, priority support, and advanced features like batch processing and custom prompts. Whether you're a student cramming for exams, a lawyer reviewing contracts, or a researcher analyzing papers, Side Reader transforms your AI chatbot into a full-fledged document assistant. Try it today and experience seamless PDF interaction on ChatGPT, Claude, and DeepSeek.
