Check content originality and detect AI-generated writing — start free, with paid plans for higher volume.
2 tools in totalContent tools check the originality and authorship of a piece of writing before it goes live — whether it matches text already published elsewhere on the web, and whether it shows the patterns typical of AI-generated writing. Both are checks worth running before publishing anything meant to represent original, human-authored work.
Each check compares submitted text against a broad index of published web content and known AI writing patterns, returning a detailed, page-by-page or sentence-level breakdown rather than a single unexplained score.
Confirm a draft is fully original before publishing, and catch accidental overlap with existing sources.
Screen freelance or AI-assisted content for originality before it goes live under the brand's name.
Check written work for both plagiarism and AI authorship before submission or grading.
Double-check your own drafts before sending them to a client, catching accidental overlap or AI-flagged phrasing first.
Both the Plagiarism Checker and AI Content Detector let you run a check for free, up to a limited amount of text per scan — enough to try either tool properly and check a typical blog post or short article without paying anything upfront. Results come back in seconds with a detailed, sentence-by-sentence or source-by-source breakdown, not just a single vague score.
For longer documents, bulk checking, or regular ongoing use, paid plans unlock higher word limits and additional usage. That makes the free tier a good fit for occasional, one-off checks, while a plan makes more sense for agencies, publishers, or anyone screening content on a recurring basis.
