Bates numbering without expensive software
Bates numbers give every page in a case a unique identifier, so lawyers can refer to "ACME000214" and everyone finds the same page. The numbers must run in order across the whole production, which is why this tool continues numbering from one file to the next.
The files are numbered on your own device. Nothing is uploaded, which matters for privileged and confidential material.
Tip: Number files in the right order: add them one by one, or remove and re-add any that are out of place.
Your files stay on your device
Most online PDF sites upload your documents to their servers. Aleynray Ai does the work inside your browser instead, on your own computer or phone.
Nothing is sent anywhere, so contracts, bank statements, IDs and medical forms stay private, and there is no waiting for uploads.
