Overview
Master Key scans manuscripts against a database of published works to detect unintended similarities that could trigger copyright claims, and identifies signs that AI systems have trained on or copied the author's work. Authors get a detailed similarity and provenance report before publishing, eliminating guesswork about whether their writing is too close to existing published work or has been appropriated by AI systems.
The outcome: peace of mind before publication. Writers know exactly what matches exist between their manuscript and published works, whether AI has been trained on their content, and can make informed decisions about revisions or publishing strategy without legal surprises.
Mission
Value Proposition
Master Key helps writers and authors — fiction and nonfiction — check their manuscripts against a broad database of published works (from famous bestsellers to obscure indie titles) to detect unintended similarities that could lead to copyright claims. It also scans for signs that AI systems have been trained on or directly copied the author's work. Instead of guessing whether a passage is too close to an existing work — or worrying about AI using their writing without credit — authors get a clear similarity and provenance report before publishing.
Target Customer
Independent authors, self-publishers, ghostwriters, small publishing houses, and content creators who produce long-form written work (fiction or nonfiction) and need affordable, pre-publication copyright peace of mind — including reassurance that AI hasn't appropriated their voice or content.
