Local processing
In this prototype, uploaded spreadsheets and PDFs are parsed in your browser. There is no account, upload server, cloud storage, or database.
Privacy by architecture
Your files stay in your browser.
Native text only
PDF.js reads selectable text already embedded in the live PDF. OCR is intentionally excluded, and scanned artwork will return a clear error.
Optional local AI
AI-assisted matching is off by default. If enabled, a small open model runs in a dedicated browser worker. It can suggest wording equivalence but never approve a numeric mismatch.
