What bugs you about paperwork?
Crooked scans you keep fixing?
Finds the paper edges, straightens the perspective and whitens the background. Usually you just confirm.
Thinking up file names?
It names the document from its content: “Invoice – Elektro Hruška – 12 Aug 2026”.
Looking for one receipt among hundreds?
Type a word — a name, a number — and it finds it inside the text.
Lost in a wall of text?
The overview pulls out what matters: amount, due date, account, reference.
A letter in a foreign language?
Translates the whole document into English, Czech, German, Polish or Ukrainian.
Need a signature?
Sign with your finger right on your phone and send it back.
Folded corner, chopped-off scan?
It notices when part of the page sticks out past the edge and keeps the whole document — no missing corner, no slice of table.
