Bloxx Work / Alternatives / Adobe Acrobat Sign

An alternative to Adobe Acrobat Sign
where an AI fills it in and a person signs.

Adobe Acrobat Sign is Adobe's e-signature service, included with Acrobat plans. Bloxx Work sends a PDF for signing. Each person gets their own link, they or their AI fill in the details, and only a person can sign.

Adobe Acrobat Sign pricing: Filling and signing a PDF yourself online is free and needs no account. Acrobat Standard is $14.99 a month on a yearly plan billed monthly; Teams is $16.99 per licence.

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.
