The Desk is the review layer between grading and your students. The machine grades; you rule. Every score surfaces for your review, you override anything you disagree with, and a single ruling propagates to every matching case in the stack. Nothing reaches students until you approve.
The Desk
The machine grades.
You judge.
Digital Red Pen grades — you judge. Control is returned, not removed. The Desk is the mandatory review step between the grading engine and any grade that reaches a student.
Get started →The flow: grade → Desk → report
The engine grades — in parallel
The grading pipeline reads every student's handwritten work in parallel — each paper processed independently, at the same time. It assigns partial credit from the steps shown and produces a score for every problem. Low-confidence work is flagged rather than guessed at.
You review at The Desk
Every grade surfaces at The Desk for your review. Override any score — change point values, adjust partial credit, mark a problem for re-examination. Issue a ruling and it propagates automatically to every matching case in the stack.
You approve the report
When you're satisfied, you approve the batch. The final report — per-student grades, breakdowns, class analytics — reflects your decisions, not just the engine's proposals.
What The Desk puts in your hands
Full grade review
Every score from the grading run surfaces at The Desk. Nothing bypasses you — the system proposes, you dispose.
Override any grade
Change any point value. Add context. Route a problem back for manual review. Your word is final.
Propagating rulings
Issue one ruling — it applies to every student who made the same error or showed the same work. One decision covers the class instead of marking the same thing 160 times.
Honest-hole routing
Graph-heavy problems and other low-confidence items are flagged and routed directly to you rather than graded with false confidence. You see what the system knows and what it doesn't.
"I checked it against my own Algebra 2 grading. It agreed with me about as well as two good teachers agree with each other. Honestly, on the Sunday nights I graded after 9 pm, it was more consistent than I was — I was handing different scores to kids for the same work depending on how tired I felt. The machine doesn't have bad days."— Zack Alexander, co-founder and secondary math teacher
Digital Red Pen grades — you judge.
Gradescope
Gradescope helps you grade faster. Its AI groups similar student answers and the teacher reviews and grades each group. The teacher is still grading — just working through clusters instead of individual papers. It is AI-assisted grading.
Digital Red Pen
Digital Red Pen reads each student's individual handwritten work, assigns partial credit from the steps shown, and produces a score. The teacher judges those scores at The Desk — overriding, issuing propagating rulings, and approving the final report. The teacher is judging, not grading.

Does the AI replace my judgment?
No. The Desk is a mandatory step between grading and report issuance. Every grade surfaces for your review before anything reaches students. You override any grade, add rulings, and approve the final report. The grading engine scores the work; you judge whether the score is right.
What does it mean that rulings propagate?
When you override a grade or issue a ruling at The Desk, that ruling applies automatically to every matching case in the stack. If you decide that a particular error type on problem 4 deserves 1 point instead of 0, one decision covers every student who made the same error — you don't mark the same thing 160 times.
How is Digital Red Pen different from Gradescope?
Gradescope helps you grade faster — it uses AI to group similar answers, and the teacher still grades each group. Digital Red Pen grades — the system reads each student's handwritten work, assigns partial credit from the steps shown, and the teacher judges the results via The Desk. The workflow is different: Gradescope reduces the grading workload for the teacher; Digital Red Pen does the grading and puts the teacher in the judge role.

Can I override any grade?
Yes. Every grade the system assigns is a proposal. You can override any score at The Desk — change point values, add context, flag a problem for manual re-review. Nothing is final until you approve it.
What happens to problems the system isn't confident about?
Low-confidence work — such as graph-heavy problems where handwritten graphs are difficult to parse reliably — is flagged and routed directly to you at The Desk rather than graded with false confidence. You get the complete picture: the grades the system is confident in and the ones it is handing back.
