"Harry Potter at Home" brings together a number of resources related to the international franchise, including free access to the audiobook version of the first installment in the series.
"Harry Potter and the Philosopher's Stone" has been added to Audible's library of free books as part of its partnership with the platform, making it immediately available in several different languages for free, and without requiring a subscription to the Amazon-owned audiobook service.
Other features of the hub include articles, puzzles and videos, made available by publishers Bloomsbury and Scholastic.
"Parents, teachers and carers working to keep children amused and interested while we're on lockdown might need a bit of magic," Rowling said as she announced the launch.
"For over twenty years now, Hogwarts has been an escape for all -- for readers and fans, young and old," the website organizers added in a post introducing the platform.
"During the strange times we now find ourselves in, we want to welcome you back to Hogwarts, where you will find a friendly retreat for you, your family and those you are caring for."
