Compare prepaid text searches with a recurring credit allowance and its data controls.
THE ATN TAKE · EDITORIAL ASSESSMENT
Copyscape suits evaluating occasional text matches with metered searches; Copyleaks packages repeated checks and additional analysis in a subscription. Estimate the same set of documents and rechecks for each. Privacy controls, permission to submit the text and human review matter more than an unverified detector-accuracy claim. [1][2][3][5]
CopyscapeFind matching web text for an existing page or a submitted draft. [1][2]
CopyleaksText plagiarism and AI-analysis reports. This comparison does not assess the accuracy of either detector. [3]
Free starting point
CopyscapePublic-URL searches return up to ten results, with additional scan limits. [2]
CopyleaksStart-for-free access is advertised; a continuing free credit allocation was not established. [3]
Paid billing model
CopyscapePremium prepaid searches: 3 cents for the first 200 words, then 1 cent per additional 100 words or part. Confirm currency and minimum purchase before paying. [1][2]
CopyscapePremium accepts pasted text and PDF/Word documents, plus URL batches and the documented API. [1]
CopyleaksMultiple-file upload, browser extension and Google Docs integration are listed. [3]
Usage limits
CopyscapeBatch Search supports up to 10,000 pages per operation; each page and API request is billed as an individual search. [2]
CopyleaksPersonal has 100 unified credits per month: up to 25,000 words OR 100 images. Plan changes replace the current plan and can forfeit remaining credits. [3]
Uploaded material
CopyscapePrivate Index is a product feature, not proof of a complete retention policy. The FAQ’s privacy link returned terms; upload retention and reuse remain unresolved. [2][4]
CopyleaksPolicy describes model training with a support-based opt-out. Shared Data Hub has separate controls; matching passages may be visible to other users. [5]
Use and result limitations
CopyscapeResults can miss unindexed content and do not certify ownership. Only the documented API permits automated querying. Adult-business permission was not established. [4]
CopyleaksTerms prohibit pornographic use and require rights to submitted content. General adult-business eligibility is not established. [6]
Affiliate status
CopyscapeNo public commission program was verified in the official pages or the targeted official-site search. No tracking link or application was created. [1][2]
CopyleaksPublic Awin offer claims 15% recurring customer-lifetime commission, a 30-day cookie and US$50 payout threshold. ATN acceptance is unverified. [7]
Consider it forATN assessment
CopyscapeOccasional permitted text searches where metered use fits better than a recurring allowance. Review matches before drawing conclusions. [1][2][4]
CopyleaksA recurring, permitted editorial workflow where the shared credit budget and upload controls have been checked first. [3][5][6]
For non-graphic editorial and business text you are authorized to submit. Similarity reports need human review; they do not prove ownership, plagiarism, AI authorship or a successful takedown. No accuracy testing has been performed. A feature listing does not establish adult-business permission.
Copyscape meters words in each search, including each page in a batch. Copyleaks uses a shared credit allowance, and changing plans can forfeit unused credits. Compare your real monthly workload and repeat checks, not a per-search amount with a monthly headline. [2][3]
Resolve upload handling
Copyscape’s private-index feature does not resolve the missing retention policy. Copyleaks documents training and Shared Data Hub controls separately, including possible visibility of matching passages. Review those controls before submitting confidential client or creator drafts. [1][4][5]
Review evidence before acting
Copyscape disclaims ownership certification and complete detection. Copyleaks’s terms restrict pornographic use and require upload rights. A match is a reason to inspect the original context and permissions; it is not an automatic accusation, authorship finding or removal outcome. [4][6]
