Simply upload one document of uncertain authorship and one or more documents by the author you suspect to have written the unknown document. Envelope uses a small handful of "best performing" methods carefully curated from the more than one million stylometric analyses commonly used by our expert analysts. Then, it reports its findings: the likelihood that the unknown document was authored by the same person as the known document(s). It's that simple!
One you have reviewed the results, our expert analysts can assist you in performing additional detailed analysis if you require forensic quality results (for instance, if you wish to use the results of the analysis in legal proceedings). Envelope allows you to see the likely outcome of your query quickly and at a great value before you commit to a full forensic-quality analysis.
