Acadly AI returns an originality gauge, a plagiarism gauge, and a matched-spans list with source links — the same output shape as Copyleaks. It also includes the Research Writer, Slide Generator, Chart Builder, Grammar, Paraphrase, Humanizer, Detector, and Document Chat in one Pro plan at $17.99/mo.
Copyleaks is a plagiarism and AI content detection platform with strong cross-language support, full website scanning, and LMS integrations. Personal is $13.99/mo monthly with 100 scan credits. The next tier, Business / Pro, jumps to $74.99/mo with 1,000 credits and team analytics — a price point aimed at institutions, not individuals. A limited free trial is available.

Frequently asked
Is Acadly AI's plagiarism checker comparable to Copyleaks?
+
For per-author submission checks, yes. Acadly AI returns matched spans with source links in the same shape as Copyleaks. Copyleaks' repository access and full-website crawl are deeper, which matters for editors but rarely for individual authors checking their own work.
Does Acadly AI support cross-language plagiarism detection?
+
Not at the same depth as Copyleaks. If your manuscript mixes multiple languages or you need translation-aware plagiarism matching, Copyleaks is stronger. For English-first academic writing, Acadly AI handles the common case.
Why is the Copyleaks price jump from $13.99 to $74.99 so steep?
+
The Business plan is priced for institutions running classroom-scale scans. As an individual, the right comparison is Personal at $13.99 against Acadly AI Pro at $17.99, and on that comparison Acadly AI is broader — nine bundled tools instead of one.
