Arc is based on Chromium, but you wouldn't guess it from the browser's appearance. Arc has arguably the cleanest interface of any browser ever. The website is in the middle, and all actions take place in the sidebar on the left (except for a pop-up on the right side that you can open to see your extensions). You get an address bar on top, then a section called "Favorites", which are like bookmarks but act more like open tabs when clicked. Then you have pinned tabs, which stay open, and "today tabs", which close after a set amount of time. Tabs are divided into Spaces, which you can cycle through by swiping or using icons at the bottom of the side bar, and can be organized using folders within each space. There is also another menu bar that you can access by swiping left after the last Space, which controls some other features and an archive of deleted tabs, as well as accessing files from your computer.

Unlike other browsers that keep releasing new features that pile up and clutter the interface, Arc only keeps the most useful features, including some pretty unique ones. A feature called Boosts allows you to customize websites by changing colors, fonts, sizes, and even deleting elements. Notes, a rather self explanatory feature, is used for notes, while another feature called Easels is similar to Opera's Pinboards, but with the added benefit of being able to add interactive site widgets. Another cool feature is Little Arc, which opens a small, one-tab Arc window on top of another app when you press Command + Option + N, meaning you can use Arc as a secondary browser even if it isn't your primary one. The browser also has split screen tab support for up to four tabs, and a tool called Peek that opens links in a pop-up above the current tab instead of creating a new one, though you can still expand it into a full tab if you want.

 In the privacy category, we find one of the browser's few downsides. While Arc has an excellent privacy policy and does not track you, it does not have a blocker to extend this privacy to the sites you visit. While the tracking issue can be resolved with extensions like uBlock Origin (which is installed by default), Panopticlick found the browser to have a very unique fingerprint among browsers tested with the tool. It is important to note that the browser was only released five days ago as of time of writing, so it's score will probably get better as it gains popularity and receives new updates. 

Arc is a very unique browser. Its developers have rethought the way we interact with the internet and created something new. They are dedicated to providing users with a useful and meaningful browsing experience, and I applaud them in their efforts. That being said, Arc is also a very new browser. It is still in its beta phase and will require much more development in order to truly compete with established browsers. I think that Arc has the potential to revolutionize the way we use the web, and I wish the team at The Browser Company the best as they continue to develop and improve this new software. Using Arc is an interesting experience, and even if you don't end up using it as your primary browser, I highly encourage you to try it out. It will change your perspective on technology forever. The story of Arc is an inspirational one; one of creativity, ingenuity, hard work, and a sincere desire to make a difference in the world. It is the story of a group of people with an idea who got together and made it a reality. Whatever the future holds for this browser, I hope its lessons are incorporated into the way we use technology. They will change the web for the better. Anyway, on to the grading.
