You can run Natalog without a subscription in demo mode. Just click the "Try Natalog without an account" link on the sign-in page after installing and starting Natalog. In this mode, Natalog has most of the features of the regular version; however, it discards all changes that you make. After you exit the demo, a short survey will open in your browser. Please complete the survey and help us better tailor Natalog to your needs.
