Why DraftProof
Prepare. Improve. Prove.
AI detectors flag your writing after you submit — DraftProof works before, on an engine we built and tuned ourselves: a fine-tuned detection model, sentence-level deep scan, and grounding checks that tell you why — not just a number.
Under the hood
A detector we fine-tuned ourselves
Not an off-the-shelf API. DraftProof runs its own model, fine-tuned on frontier-AI output and thousands of real essays — and re-tuned as new frontier models ship, so detection keeps pace with the tools students actually use.
Calibrated for non-native English writers
Detectors are notorious for flagging fluent ESL writing as "AI." Every scoring change is gated against a 272-essay corpus of real non-native English writing and ships only if false positives stay low — 0.8% on lower-proficiency writers at our standard threshold.
Deep scan reads at sentence level
A separate deep-reading model scores your draft sentence by sentence, then fuses with the pattern signal — so no single noisy number can swing a verdict, and you see exactly which lines drive the score.
Claim-graph grounding
DraftProof maps the claims in your argument and checks whether each is actually supported by its cited source — surfacing the ungrounded, generic assertions that are the real reason writing reads as AI-generated.

DraftProof-only features
Diagnose what's flagged and why — before you submit.
Policy risk (dual-mode)
Two scores from one engine — AI-Allowed and AI-Restricted — matching your institution's actual policy, not a single generic verdict.
Submission risk framing
"Can you defend this as your own work?" — framed across three layers: text pattern, thinking ownership, and academic grounding.
Critical thinking control
Five dimensions — specific context, student judgement, reasoning trail, evidence grounding, AI dependency — tell you what to think harder about.
Works inside Word & Google Docs
