About ExtraProof

ExtraProof by Extraara.

ExtraProof makes documented writing sessions verifiable. Writer documents the writing process. Creation Records carry the signed claims. Verify gives recipients a clear technical finding.

01

Share the process behind the work.

Sharing a finished document usually shares only the result. ExtraProof adds a record of the observed session. Recipients gain additional information that they can assess under transparent rules.

02

A shared language for evidence.

File binding, event chains and key trust mean the same thing for a university assignment as they do for an editorial submission or a business report. The context changes the requirements, not the meaning of a technical finding.

03

Technology with clear responsibilities.

Extraara combines local processing with an openly described verification scope. Writers decide how to share their records. Recipients are responsible for substantive assessment. The software makes the technical claims between them understandable.
