Your text (draft) is stored in your web browser only (on your device only) and is not available to anyone. But if you want to send your text note to your friend or to another device, you can create a Temporary link to sync your text.
In addition, this online notepad works like a “multi-page” notepad and allows you to manage drafts (notes). All created notes (drafts) are named “by date” and “time”, to easily identify your note.
ShareText.me is not a “text editor” and has no text formatting. If you need a real multifunctional special text editor with text formatting tools etc., you can find a lot of different applications (any Word processor or Text editor) for your special needs. Or you can download and install, for example the free and open-source LibreOffice Writer (for Windows, Mac OS X and Linux).
