Build me a local web app for checking plagiarism and rewriting academic text.

I want a dark, polished landing page with a dramatic animated particle sphere, then a dashboard where I can upload a PDF, DOCX, or TXT file, run an analysis, and see the results in the browser. The app should highlight matched text with exact character positions, show a clear report of what looks copied or closely paraphrased, and let me download a professional PDF report with the highlights included.

Also add a rewrite workspace that can take selected text and rewrite it in different tones like academic, standard, or creative using a local Ollama model. Make the analysis run in the background so the page can poll for status instead of freezing. If anything needs current setup details, look up the latest docs online and make it work cleanly for local use.
