Why it surfaced

Capka makes a concrete promise: put in one messy ZIP and get back a PDF report plus an Excel file. Its distinctive mechanism is a separate Linux sandbox for every chat, with tools such as Python, Node, LibreOffice, FFmpeg, Playwright, and OCR, plus recurring automations that leave finished files on your own server.
