Files & vision.
Give NEXUS an image to inspect or load a dataset for analysis. Files are handled in your current browser until you choose to send them to AI.
PDF text is extracted in your browser using PDF.js; when you ask NEXUS about it, extracted text is sent to Cloudflare Workers AI. Scanned/image-only PDFs need OCR, which is not included yet. Spreadsheet calculations and charts run locally. Avoid uploading sensitive personal information.
