How 100% Client-Side AI Works (Zero Trust Security)
Traditional \"Chat with PDF\" tools require you to upload your sensitive files to their backend servers. This is a massive privacy risk.
SmartCalcTools takes a revolutionary \"Zero Trust\" approach. When you upload a PDF here, our website downloads a highly-optimized Multilingual AI model directly into your browser cache, running on your local machine.
The RAG Architecture (Retrieval-Augmented Generation)
1. Extraction: Your PDF is parsed locally using PDF.js.
2. Chunking: The text is split into paragraphs.
3. Embedding: The local AI converts each paragraph into a mathematical Vector representation.
4. Semantic Search: When you ask a question, the AI converts your question into a vector and uses Cosine Similarity to find the exact paragraph.
