As much as cyberpunk fiction loves to play with Christian mythology, reality always tries to keep up with this trend. In 2018 happened the beta launch of Sentinel, an angel artificial intelligence (AI) technology created by AdBlock Plus, claiming to be able to detect ads even without lists typically used in these matters. Browser adblocker is almost an irreplaceable part of internet users’ life, what else?

Thanks to the AI, our ad blocker is able to detect ads just like a human does.


Still a pretty recent development, AI-powered adblockers are taking the market step by step. Unlike traditional ones relying on predefined lists, they rave on real-time machine learning algorithms. Meaning: they can learn to distinguish between page content, and detect ads by analyzing patterns, features, and structure. These rascals aren’t covered by conventional methods. You know, native ones that completely blend with the rest of the site? AI-powered adblocker can work even like a preventive method, identifying not just existing ad formats, but also predicting and blocking new, unseen ones. In essence, they adapt to changes in ad delivery techniques, reducing the effectiveness of advertisers’ attempts to circumvent ad blocking. Despite the evolving strategies of advertisers, it provides users with a new level experience. And one of the best things today — you can download adblocker you need for free.

With all that and a little more in mind, we created our built-in blocker and are happy to introduce you to AdBlock 2.0.

Rooting for tranquility

But first, traditionally, a tiny sidetrack.

The first brick was laid in 2002 by Henrik Aasted Sørensen. Heritage of which is quite a life-saver today, AdBlock was created in response to an already aggressive advertisement, which destructive and disruptive nature was invasively escorting the expansion of the Internet. Popups and banners were so common, that they almost could scratch your eye. Not to mention how easy it is to get sidetracked. Can’t name it a pleasant experience.

A browser adblocker extension created by the Danish student filtered page content against a set of rules (commonly known as filter lists) a user had to provide. These regulations designated specific elements, typically recognized by their originating address, to be eliminated from the page. When a webpage was accessed, any components matching these filter list parameters were obstructed, effectively “concealing” advertisements from the user’s view.

Simple and effective it worked out the purpose of fighting against the all-seeing hand of the market, laying the groundwork for future generations.

In 2006 the fork of the original AdBlock is developed by Wladimir Palant, bringing to the table something that will ease the burden on the users — pre-made filter lists. These lists, such as the widely-used EasyList, allow users to effectively block ads without needing to create their own filters.

But what is the growth without controversy and users questioning decisions? 2010, AdblockPlus announces a feature called Acceptable Ads. A kind of white list of ads that the extension will let display. At first glance, it goes against the idea of the whole deal. But the interesting part is, there are still debates on the issues the popularity of adblockers brought to businesses, while even 13 years ago Adblock Plus noted it and tried to find a balance while still protecting users from the most disruptive and intrusive ads. This feature stays still till that very day, though many users were concerned that it wasn’t the best AdBlock decision.

What makes a good adblocker? Accessibility. As soon as Apple started trying to ride the wave of users’ privacy after doubts were raised with all the coming files, they also introduced support for content blocking with the launch of iOS 9 in 2015. The first time adblockers were allowed for mobile and not surprising that somewhere around that time the mobile browser Brave is launched, also with built-in adblocking capabilities.

Sure enough, where one corporate giant succeeds, another one tries not to drag behind. Google wanted a piece of cake too, though being more cautious to keep their word — concerns about blocking ads completely will bring a crisis and fall of the businesses depending on it. So they introduce a built-in free adblocker to Chrome, which blocks ads on sites that fail to comply with the Better Ads Standards. All and all, it brings adblocking to a much wider audience. And as we mentioned at the start, the same year AdBlock Plus announces the beta launch of AI-powered adblocker Sentinel and invited people worldwide to train neural network algorithms: “Sentinel will learn to block Facebook ads first, and will then learn to recognise other ad types.” From a simple free adblocker extension to a “rebellion” in 16 years.

And most importantly, in 2018 “the Rust community decided to improve the programming experience for a few distinct domains.”

How it relates to the subject and what do we have now? Bingo! The AI-powered adblocker written in Rust is doubtfully the best adblocker. It’s kind you can find in Brave browser and our Sidekick with Adblocker 2.0. The adblocker browser asked for.
