A browser extension released by artist and researcher Tega Brain. It narrows search results to content published before November 30, 2022 ─ the day ChatGPT was made publicly available ─ surfacing the “human-written web” from before generative AI became widespread. Using Google’s date filter, it searches across Google and DuckDuckGo as well as sites such as Reddit, Stack Exchange, Quora, Pinterest, YouTube, and Mumsnet. Released in late 2025 as a response to so-called “AI slop” (mass-produced, low-quality AI content) and the “dead internet theory,” it is free to use on Chrome and Firefox, and its source code is published on GitHub.
Key Features
- A time filter anchored to ChatGPT’s launch date: Only pages published before November 30, 2022 are shown. Content mass-produced since the generative AI boom is separated out mechanically by publication date rather than by judging the content itself
- Cross-platform search of major sites: In addition to date-restricted searches on Google and DuckDuckGo, it can search Reddit, Stack Exchange, Quora, Pinterest, YouTube, Mumsnet, and other sites where AI slop has become noticeable
- Choose target sites with checkboxes: Select the platforms before searching, and each set of results opens in its own tab. Pop-up permission is required to display them all at once
- A lightweight mechanism built on existing search: It maintains no index of its own, simply combining Google’s site-restricted search with a date restriction. The developer states plainly that “it’s very easy to do these searches without this extension; this tool is just a convenience”
- Open source and free: The source code is published on GitHub (Anti-Capitalist Software License), and the extension can be installed for free from the official Chrome and Firefox stores
- A proposal about attitude, not technology: The creator frames it as “a small act of digital refusal,” and is explicit that a browser extension alone will not solve the problem of AI slop

Pros & Cons
✅ Pros
- Makes it easier to reach experience-based posts in areas ─ recipes, DIY, troubleshooting ─ that tend to be buried under AI-generated articles
- Usable immediately after installation, with no account registration or setup
- The mechanism is simple, and what it does can be verified in the source code
- Free, and available for both Chrome and Firefox
⚠️ Cons
- Nothing published after December 2022 appears, so it cannot be used to research current products, news, or timely topics
- The assumption that “before November 30, 2022 = written by a human” is only an approximation; spam and auto-generated pages from before that date are not filtered out
- Because the search is really Google’s date filter, results depend on Google’s index and on how accurately publication dates are detected
- The set of supported sites is limited, and because multiple tabs open at once, pop-up blocker settings need adjusting

Summary
Slop Evader is a simple, easy-to-grasp tool that divides search results along a single line ─ “before ChatGPT’s launch date” ─ rather than judging the content itself. It cannot help with research that requires current information, but it works well as a supplementary search box when looking for experience-based information. It is free and open source, so if the rise of AI-generated content has been bothering you, the quickest way to judge it is to install it and run a few searches.
