What It Is

AiSList & AiBlock is an open-source blocking toolkit for YouTube: AiSList is a community-maintained blocklist of AI slop channels, while AiBlock is a browser extension available for Firefox and Chrome. Its goal is not to generate content, but to help users hide low-quality AI-generated channel content from their YouTube recommendations and browsing experience.

Core Features and User Experience

Based on the main description, the tool uses a list-based filtering mechanism rather than a disclosed AI model detection system. The extension hides content from channels already included in the blocklist in real time while users browse YouTube, without requiring a page refresh. The list can be automatically synced from GitHub, so newly added channels should theoretically take effect automatically. Users can also submit suspicious channels via the extension’s right-click menu, a small flag inside the video player, the extension popup, Discord, or GitHub Issues, creating a community-driven contribution workflow.

Pricing, Privacy, and Integrations

In terms of pricing, both the Firefox and Chrome versions are listed as free to install. The main text does not mention any paid version, subscription, or usage quota. Privacy is one of its key selling points: the page clearly states that there is no tracking, no analytics, and no data collection. The extension only reads the blocklist and filters feeds locally. As for integrations, it mainly relies on browser extensions, automatic GitHub syncing, the Discord community, and GitHub repository collaboration. No open API or enterprise-grade management features are mentioned.

Pros and Cons

Its strengths are that it is free, open-source, transparent, privacy-friendly, and supports mainstream desktop browsers, making it suitable for YouTube users who do not want to repeatedly click “Don’t recommend channel” manually. The drawbacks are also clear: it depends on a community-maintained list, while coverage, false-positive rates, and review standards are not disclosed in the main text. It currently focuses only on YouTube, with no mention of mobile support, Safari, Edge, or other video platforms. It also does not show real blocking counts, user scale, or effectiveness data.

Who It’s For and Access from China

It is suitable for heavy YouTube users, creators and viewers who dislike mass-produced low-quality AI content, and privacy-conscious users who prefer open-source, auditable tools. Regarding access from China, the main text does not discuss network availability. However, since the core use case depends on YouTube, GitHub, and Discord—and YouTube/Discord are generally restricted in mainland China—actual use will likely require an additional network setup. Alternatives may include YouTube’s built-in “Don’t recommend channel” feature, custom uBlock Origin rules, or other content-filtering extensions.
