It reads the native PDF text layer, or runs Apple's Vision text recognition on scanned paper receipts, and applies deterministic Swift extraction rules to turn the printed date, vendor, invoice or reference number, amount, currency, and expense category into a clean filename such as <code>2026-03-31_GitHub_INV-401928_21.00USD.pdf</code>. Every extracted value is outlined in colour on the PDF preview, and uncertain fields pause in amber for one-click selection. Name collisions get a suffix like <code>_(2)</code> instead of overwriting anything. Every rename is logged to a local SQLite undo journal, and undo checks inode and hash before it restores a name. You can test bundled sample invoices in the app without a key at <a href="https://stampname.app/download" rel="noopener noreferrer">https://stampname.app/download</a>, or claim one of the first 50 free Pro Lifetime licenses (0 USD checkout via Polar, no card needed) at <a href="https://stampname.app/free?utm_source=devto" rel="noopener noreferrer">https://stampname.app/free?utm_source=devto</a>. Regular pricing is 39.99 USD for Lifetime or 19.99 USD for Yearly, for up to 3 Macs.</p> showdev macos swift productivity
