About this extension
Extinction is an ultra-lightweight AI content blocker browser extension powered by regex-based pattern matching and linguistic analysis.

Why Block AI?

The World Wide Web is becoming increasingly plagued with low-quality AI-generated content. The content AI produces is often misleading or blatantly incorrect. While some may not particularly see this is an issue, many people wish to escape from or completely hide such content.

We, the maintainers of Extinction, hope to rebuild a more creative and trustworthy form of the incredible invention known as the Internet, liberated from the hands of slop. Extinction is made specifically for the purpose of discouraging the consumption of AI-produced material distributed online.

What Makes Extinction Different?

Traditional AI content detectors rely on machine learning and heavy analysis to product a result. Besides the irony of using such a mechanism, these AI detectors are often less trustworthy when it comes to respecting user privacy. Since the content is fed into an external API, users cannot reliably confirm that the data they send is kept confidential.

Even beyond the privacy aspect, these tools are surprisingly inaccurate. Hence, a well-tuned AI content blocker based on mere pattern-matching and simple structure analysis has the potential to outperform or, at least, be on par with machine-based AI detectors in terms of accuracy.

Extinction does not send any data to an external endpoint; all analyses are done locally, meaning there is no compromise in user privacy. It does not use machine-learning to classify text, but rather simple pattern matching with regular expressions (regexes) paired with sentence variation analyses.

How Foolproof is Extinction?

Extinction is not 100% accurate, just like any other AI detection tool. However, in many cases, it appears to be nearly as accurate as traditional tools in correctly identifying human-written and AI-generated text. In rare situations, it may even perform better than certain detection tools.

Since Extinction is based on a very simple and lightweight detection mechanism, it will occasionally produce false positives and false negatives. For this reason, Extinction has a "trusted sites" feature, which can be used to exclude certain pages or domains from scans.
