ExtraProof

The text. Its history. A connection you can check.

Writer accompanies a writing session. The Creation Record documents observed steps in the process. Verify checks whether the record and file match.

The process stays traceable.

A Creation Record links the process to a version of the text.

Written assignments in education

From the first draft to the submitted version.

Take a coursework assignment: teachers agree on the task and permitted aids. Learners document selected stages of their work and submit the record alongside their text.

For education
  1. Write

    Learners deliberately start a session in the agreed writing environment. What process data is recorded and who may see it is settled beforehand.

    What learners see and decide
  2. Share the record

    A signed process record (Creation Record) documents observed events and gaps. The writer decides whether to share the record and the associated file.

    Data flows and sharing
  3. Review together

    Teachers check the record and file locally in their browser. Gaps need context and do not, by themselves, establish misconduct. Academic judgement stays with the teachers.

Working with education

A real assignment. A pilot together.

One real assignment, a small group and a shared question: does the documented writing process help when questions arise about a submission? We support setup and evaluation. Duration, workload and costs are agreed before the start.

Extraara is based in Västernorrland, Sweden. Institutions outside Sweden can also enquire about a pilot. We discuss whether to work on site or remotely in our first conversation.
