Most submissions are graded in 5-10 minutes.

Quality takes time—even for AI. Each submission goes through multiple specialized passes: first, an 'Investigator' AI scans your documents to extract evidence for each rubric criterion. Then, an 'Evaluator' scores each dimension using calibrated benchmarks (what does 'excellent' vs. 'passing' actually look like?). An 'Auditor' then reviews all scores for consistency and catches potential hallucinations. Finally, a 'Coach' generates personalized improvement recommendations. This multi-stage process is why our grades align 90%+ with human experts—and why we catch nuances that instant AI responses miss.
