Keep Everything is a Mac utility that provides you with a quick solution for saving websites for offline access. This means that you can store a copy of a webpage in this program and access it even you're not connected to the Internet. This type of tools proves to be of good use when traveling or when you don't have any Internet signal from your provider due to a technical issue.
The program comes with a nicely-designed and intuitive interface where you can paste the URL of the website you wish to save, preview the webpage, and even export it to your local directories. Keep Everything also provides you with the ability to share websites via email, directly from its main toolbar.
Another important advantage is that you have access to an option to automatically sync the stored content across your Dropbox account. This way, you can access your saved websites from another computer or from your smartphone.
Two things bother me about this utility: the fact that it's limited in terms of storing content (you can store up to 100 sites) and that it supports only 2 output formats when exporting web pages to your local folders.
Still, it's definitely worth giving Keep Everything a try if none of the aforementioned aspects mean anything to you. It works 100%, is very intuitive, and comes without a price.
