FAQ

Frequently asked questions

Grammarly doesn't check citations. Turnitin only tells you about similarity. We actually read every reference in your paper and tell you if it exists, matches your claim, and isn't AI-hallucinated, plus sentence-level AI detection. One upload, less than a coffee.
CiteSure is close to us on citation verification. Check Your Draft is broader: we check whether your references exist and make sense in your draft, then add sentence-level AI detection in the same upload. Use CiteSure if you only want citation verification. Use Check Your Draft when you want a full pre-submission risk check.
Citely.ai focuses on finding sources and verifying reference lists. Check Your Draft starts from your complete draft: we check references in context, flag suspicious or unsupported citations, and pair that with AI-writing checks so you can decide what to fix before submission.
Turnitin is built for institutions, instructors, and academic-integrity workflows. Check Your Draft is built for students before submission. Your draft does not go to your university or a shared repository, and the report explains citation and AI issues you can fix yourself.
GPTZero is strongest when your main worry is AI writing, authorship proof, or plagiarism-style similarity. Check Your Draft includes AI signals, but it also verifies citations and checks whether sources support your academic work. Use GPTZero for AI-focused review. Use Check Your Draft when references and thesis defensibility matter too.
No. We never share your draft with your university or add it to a plagiarism or training database. Your source PDF is automatically deleted 30 days after upload; analysis results stay private for 90 days so you can reopen your report.
Our model is tuned for academic prose specifically and evaluated against 120k+ student papers. We show you a per-paragraph confidence score, not a scary red percentage meant to make you panic.
It's a proofreading tool, like Grammarly. It doesn't edit your text, it just shows you what needs fixing. You do the fixing.
Upload and preview your results free, a few flagged citations and AI-flagged sentences, no card. To unlock the full report it's $26.99 one-time for Essential (3 checks, never expire) or $40.38 one-time for Complete, 30 days of unlimited checks. Both are one-time payments, no subscription.
