Editor's Verdict

Official Review

Scribbr's AI detection is genuinely free and unlimited, which differentiates it from Turnitin and most academic tools that charge per check. The detection engine has reasonable accuracy on modern AI writing but produces false positives on clean formal prose with academic register — a published scholar's writing can score as 'AI' for being dense and structured. The human proofreading service delivers APA/MLA compliance alongside substantive feedback, at the premium end of academic editing pricing. For students who need a free first pass before submission, the detector is the right starting point; treat its score as a risk signal rather than a verdict.

Cons

Limitations

AI detector can produce false positives on formal academic prose even when entirely human-written
Human proofreading service is at the premium end of academic editing pricing, starting at $20/1,000 words
AI detection score should be treated as a risk signal, not a definitive verdict on AI authorship
