Fair use is a doctrine in copyright law that allows for the use of copyrighted material without the permission of the owner in certain circumstances. It is not exempted from copyright laws, but rather allows for certain exceptions to those laws under certain conditions. Fair use depends on the character and purpose of the use of the copyrighted material, and whether it is considered transformative or non-transformative. It does not necessarily require attribution, but it is always a good idea to give credit to the original creator whenever possible.
