Description
Side Reader is a powerful Chrome extension designed to enhance your experience when working with AI chatbots like ChatGPT, Claude, and DeepSeek. It seamlessly integrates PDF reading and interaction capabilities directly into the sidebar of these platforms, transforming how you engage with documents.
With Side Reader, you can upload and view PDF files within the sidebar of your preferred AI chatbot. This allows for effortless interaction, enabling you to summarize lengthy reports, translate complex texts, or ask specific questions about the content without leaving the chat interface. The extension aims to provide AI chatbots with advanced features similar to dedicated PDF AI tools.
Key features include a great reading experience with support for PDF zoom, page navigation, and width adjustment. For documents where text selection is difficult, Side Reader offers a unique screenshot capability, allowing you to ask questions about image-based content. Furthermore, users can customize interaction button prompts, guiding the AI to generate content precisely according to their requirements. Data security is a priority, with all uploaded PDF files stored locally in your browser, ensuring Side Reader does not store any user files.
The extension offers two pricing tiers: a Free plan and a Lifetime plan. The Free plan is ideal for users looking for basic AI assistance with PDFs, offering a daily upload limit of 1 PDF, a max file size of 10MB, and history of the last 3 records. The Lifetime plan, priced at $29 one-time, provides enhanced features for users requiring advanced AI assistance, including a daily upload limit of 50 PDFs, a max file size of 50MB, capture & ask functionality, history of the last 100 records, and customer support via email, along with custom prompt features.
Side Reader is targeted at students, researchers, professionals, and anyone who frequently works with PDF documents and leverages AI chatbots for analysis, summarization, or information extraction. It bridges the gap between document content and AI conversational capabilities, making information retrieval and processing more efficient and intuitive.
