Learning features
IUPAC nomenclature, spectroscopy, and reaction mechanisms work without an account in supported browsers. Learning records and mistake review are stored in the current browser.
Mechanism Studio
Basic structure, bond, charge, curved-arrow, and text drawing are available with PNG export. Recovery data stay on the device and are not cloud-synchronized.
External services
Meimay does not use access analytics, accounts, cloud sync, or problem-report submission. Answers and structures are not sent externally unless the user explicitly starts an external lookup.
Browser requirements
Current versions of Chrome, Edge, Firefox, and Safari are targeted. Some practice, history, and drawing functions require JavaScript and browser storage.
