Frequently Asked Questions & How It Works
💡 How does client-side Extractive Summarization work?
Our extractive NLP engine processes your PDF entirely within your web browser using statistical graph algorithms (TextRank & TF-IDF matrix scoring). It breaks down the document into tokenized sentences, removes common stopwords, calculates term centrality, and boosts key introduction/conclusion sections and statistics. It selects the highest-impact original sentences and orders them chronologically without sending any data to external servers.
🔒 Is my PDF document completely private and secure?
Yes, 100%. In Client-Side Extractive NLP mode, your file never leaves your browser window. Zero bytes are uploaded to RiazHub.com or any third-party cloud server. If you choose the optional AI-Powered Abstractive mode, your browser communicates directly with Google Gemini or OpenAI using the API key you provide, which is only held in your browser session memory.
📋 What type of PDF files produce the best summary results?
Digital text PDFs—such as research papers, corporate reports, contracts, meeting minutes, financial statements, and technical specifications—yield optimal summary accuracy. If a PDF is a scanned image or photograph without an embedded text layer, the tool will alert you that Optical Character Recognition (OCR) is required.
