The cheapest way to prove your documents are authentic.
Install a free Chrome extension. When you download a PDF from a real website, NotChanged stamps a verified copy. Anyone can check it later.
AI makes forged statements and payslips easier than ever. A simple check that a file came from a real site — and hasn’t been edited since — goes a long way.
For companies
Lenders, landlords, and HR teams: ask applicants to use NotChanged before they download bank statements or payslips. Upload the stamped PDF on the verify page — you’ll see where it came from, and whether it’s still the same file.
