OSSUS Substack Books

A personal reading-library tool under development. Its purpose is to combine selected Substack serial chapters into one updating EPUB in the owner’s private reading library.

Gmail ingestion is not enabled yet. The planned import uses explicitly authorized, read-only Gmail access and configured newsletter senders. This public website contains app information only; it has no mailbox interface or account-registration form.

The application is for its owner’s personal use. It is not affiliated with or endorsed by Google, Substack, or BookOrbit.
