Direct answers
Before opening your library
Raziel.MD limits and behavior, without vague promises.
Does Raziel.MD work without internet?
Yes. Core reading, organization, and search work offline once app resources are available on the device.
Are my files sent to a server?
Not in the core flow. Your library is processed and stored locally in the browser.
Can I open a whole folder?
Yes in compatible browsers. Where file-system APIs are limited, regular import remains available.
Do I need to install anything?
No. Use it in the browser or install the PWA for a more integrated offline experience.
