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.

- DOI-level confidence

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
