Questions
Is Duplicate payment detector free?
Yes. It runs entirely in your browser and costs nothing on every plan, including Free. The file never leaves your tab.
Is my document stored?
No. Nothing is uploaded — the file is opened and processed in your browser. Close the tab and it is gone.
Is this AI?
No. Parsing is deterministic: fixed rules on the text and table positions of the document (or OCR output for scans). The same file gives the same result every time, and a value is never silently changed — unclear cells are flagged in the grid for you to check.
