What payment methods do you accept?

LINGA is a psycholinguistics company that provides authorship identity verification as a service via our proprietary Linguistic Fingerprint™ technology. Through the LINGA web application, guests complete writing prompts in order to build their Linguistic Fingerprint™. Once built, guests can discover their true selves as expressed in the form-factor of writing. Guests can also scan written documents in order to generate a unique Authorship Verification Certificate, which is certified by LINGA and available as a downloadable PDF file. This certificate indicates whether or not the scanned document matches the guest's Linguistic Fingerprint™, and is backed by our $1,000,000 Authorship Integrity Defense Guarantee℠ (Terms apply.). Individual guests can use LINGA to verify and defend authorship integrity for important written works like books, articles, papers, speeches, and more.

We regularly update the Linga web app with new features, changes, and bug fixes in order to make your experience even better.
