InvoicePilot: a private AI invoice sorter for freelancers that runs offline with Gemma 4

Описание и применение

InvoicePilot позволяет фрилансерам обрабатывать счета и квитанции офлайн, сохраняя конфиденциальность и устраняя подписки, с проверкой и ручным утверждением данных.

Задача

Freelancers must manually sift through emails, downloads, and photos of receipts to extract data into spreadsheets, while existing AI scanners risk violating NDAs and incur subscriptions.

Результат

InvoicePilot enables freelancers to process invoices offline, preserving privacy, eliminating subscription costs, and providing a validated, human‑approved CSV export.

Доказательства

Every freelancer I know has the same quarterly ritual: dig through email attachments, download folders and photos of paper receipts, then retype everything into a spreadsheet.

Источник

Everything runs on localhost. No document text, price or client name leaves the machine.

Источник

Small on-device models can invent a zero tax line when a tax breakdown exists, confuse MM/DD with DD/MM dates, or return totals that don’t add up.

Источник

A deterministic math check: the backend verifies subtotal + tax - discount = total itself, in integer minor units, and warns on any mismatch
