What only Bloxx Work does
- Each document can have a separate fill link for an AI assistant. It can complete names, dates and choices, and it has no way to sign: signature and initials fields are refused by type.
- A person signs on the page, after ticking a consent box. The signing record stores the consent text word for word.
- The signed PDF has the values burned in and a signing record appended, so it reads the same anywhere.
- Bloxx Work records a simple electronic signature. It is not for documents the law requires to be witnessed, such as deeds.
