Rubrica
Built for students

Every feature is built to answer one question: "would this pass the rubric?"

Rubrica is not a grammar checker and not an essay generator. It's a rubric-aware self-assessment tool built around the specific way students are graded.

The six things that matter

Why students choose Rubrica over generic AI feedback.

Graded against your actual rubric

Upload your brief, your rubric, and your work. We score against the criteria you'll be marked on - not a generic writing standard.

  • Any rubric format (PDF, Word, table)
  • Criterion-by-criterion breakdown
  • Marker-aligned, not generic AI advice

Evidence from your own draft

Every comment quotes the part of your text it's about. Not 'be more analytical' - instead, the actual paragraph that needs work and why.

  • Quoted source spans, not vague advice
  • Strengths + gaps per criterion
  • Concrete revision steps

One-click rewrites in your voice

Don't like a paragraph? Hit Improve. We rewrite it to address the specific criterion - keeping your tone, not pasting in robotic AI prose.

  • Voice-preserving rewrites
  • Tied to one criterion at a time
  • See original vs improved side by side

Honest when we can't grade

If something fails, we tell you in plain English and refund the credit automatically. No fake F. No silent broken submission.

  • Automatic credit refunds
  • Plain-English failure messages
  • Try again with one click

Real references, verified

Every citation is checked against CrossRef. Fabricated, hallucinated, or invented references are flagged before your tutor sees them.

  • CrossRef-backed verification
  • Catches AI-fabricated citations
  • DOI-level confidence

49¢ a check. Revisions free.

Under the hood

The details that make feedback specific

The work happening behind every grade - the kind of detail generic AI never bothers with.

Smart brief parsing

We read your assignment brief for word counts, deadlines, required sections, and directive verbs (critically evaluate vs describe) - so the feedback knows what the task actually asks.

  • Directive verb detection
  • Hidden requirement extraction
  • Word count & structure check

Brief + rubric + draft, read together

Most AI sees only your essay. Rubrica reads all three documents together - that three-way read is what makes the feedback specific instead of generic.

  • Brief alignment check
  • Rubric coverage analysis
  • Cross-referenced gaps

Privacy by design

Your drafts are never used to train AI. Reference verification runs on CrossRef (public data), not on your private writing. Built for academic integrity.

  • Not used for AI training
  • Public-only reference checks
  • Auto-deletion on request
