Is there a tool that downloads every website I visit locally and then, upon revisit, shows me my local copy for instant load, but does a diff in the background with the online version and asks me to show newer version only if there are differences?

Try https://github.com/WorldBrain/Memex, it has annotation and lets you review previously seen versions of a site as you're browsing.
