How to Block AI-Generated Videos on YouTube (and Facebook) in 2026

AI-generated video is everywhere now, and your feeds know it. If you've noticed your YouTube recommendations filling up with synthetic narrators, faceless "brainrot" compilations, and uncanny deepfake clips, you're not imagining it. This guide walks through the free ways to block AI videos on YouTube, the limits of each, and then a private, local option that also covers Facebook.

Why this is suddenly a problem in 2026

Two data points frame how big this got:

• A late-2025 study found that roughly 21% of YouTube recommendations served to new users are AI-generated slop, with an additional ~33% classified as "brainrot." (source)
• YouTube CEO Neal Mohan publicly named managing AI slop and detecting deepfakes a priority for 2026. (source)

In other words, even the platform admits the noise is a problem. Coverage of the shift notes that users are increasingly tired of the noise and looking for walls, filters, and trusted human curation. (source) Until platform-level fixes catch up, the practical move is to filter the slop yourself. Here's how.

Free method 1: YouTube's built-in controls

You already have a blunt instrument inside YouTube. On any recommendation you don't want, click the three-dot menu and choose "Don't recommend channel" or "Not interested."

• Cost: Free, no install.
• Good for: Killing a specific channel that keeps surfacing.
• The catch: It's reactive and per-channel. AI slop is produced at scale by an endless rotation of throwaway channels, so you'll be playing whack-a-mole forever. It doesn't touch Shorts shelves in any systematic way, and it does nothing on Facebook.

Use it, but don't expect it to keep up on its own.

Free method 2: uBlock Origin + community AI blocklists

If you're comfortable with a more technical setup, the power-user route is uBlock Origin combined with community-maintained filter lists like the "HUGE AI Blocklist" or "SlopBlocker," or custom Tampermonkey/Greasemonkey scripts.

• Cost: Free.
• Good for: People who already run uBlock and like maintaining their own rules.
• The catch: It requires setup and ongoing list maintenance, and filter lists can break when sites change their markup. It's a great $0 option for tinkerers, and worth knowing it exists, but it's overkill for most people who just want an install-and-go fix.

Free method 3: dedicated "hide AI" extensions

Several free browser extensions already do this, and Unslop is not first to market here. The honest rundown:

• Clarity – Hide AI Videos — Free, ~1,000 users, rated 4.6 (9 ratings). Local detection with an optional community blocklist; simple toggle and a daily counter. YouTube only (home/Shorts/recs). (listing)
• ByeAI — Free, ~956 users, rated 3.7 (3 ratings). Uses community flagging / crowd-voted hide, no account; covers AI voice/thumbnail/script/deepfake/music. YouTube only. (listing)
• AI Slop Blocker — Free, ~429 users, rated 4.6 (5 ratings). Local; blocks only self-disclosed/AI-disclosed videos and also hides Google AI Overviews. YouTube + Google Search. (listing)

If you only care about YouTube and want a free toggle, any of these is a reasonable starting point. The two trade-offs to notice: most are YouTube-only, and some rely on community/crowd-voting, meaning what gets hidden depends partly on other people's votes or a shared server.

The paid benchmark: AI Content Shield

The one proven paid product in this niche is AI Content Shield, a freemium tool. Pro runs $6/mo, or $4.95/mo billed yearly (~$59/yr). It's the most feature-rich option, spanning ~20 sites (YouTube, Facebook, TikTok, X, Instagram, Reddit, Google/Bing/DuckDuckGo, Spotify, Gmail) with keyword filters; its Facebook AI-text hiding and AI-voice blocking are Pro features. (source, pricing)

If you want the widest cross-platform coverage and don't mind a subscription, that's the one to look at. If you specifically don't want a recurring bill, accounts, or a server in the loop, read on.

The private/local option: Unslop (YouTube + Facebook)

Unslop is an AI-content blocker browser extension built around one idea: do everything on your device. It hides AI-generated videos and posts on YouTube and the Facebook main feed.

What makes it different:

• 100% local. It runs entirely client-side using only the storage permission — no account, no community server, no telemetry. Nothing about what you watch leaves your browser.
• YouTube + Facebook in one extension. It filters YouTube home, search, sidebar, and Shorts shelves, plus the Facebook main feed. Most named free competitors above are YouTube-only.
• No crowd-voting. Instead of a community flag queue, it matches each card's visible text, your custom keywords and hashtags, and the platform's "Altered or synthetic content" disclosure label. It reads declared signals, not other people's votes.
• Accurate by design. It uses whole-word matching — 16 passing matcher unit tests confirm "ai" never hits Dubai, email, or rain, so you avoid the obvious false positives.
• You stay in control. Add custom keywords, whitelist creators you trust, choose remove or blur modes, and watch a live blocked counter (total/today).
• Wide browser support. Works on Chrome, Edge, Brave, Opera, and Arc.

Honest limitations

No tool is magic, so here's the straight talk:

• Unslop is not first to market — Clarity, ByeAI, and AI Slop Blocker exist and are free.
• Detection keys off declared signals (visible text, keywords, hashtags, the disclosure label). It does not analyze pixels or audio, so AI content with no disclosure and no telltale keywords can slip through.
• It has no AI-voice acoustic detection, which AI Content Shield Pro advertises.
• Its platform coverage is narrower than AI Content Shield's ~20 sites — Unslop covers YouTube plus the Facebook main feed only.
• It has no community blocklist, by design. That keeps it local, but it also means no shared intelligence to auto-catch brand-new patterns the way Clarity's optional shared list can.

So which should you use?

• Just want a free YouTube toggle? Try Clarity, ByeAI, or AI Slop Blocker.
• A tinkerer who already runs uBlock? Add an AI blocklist and you're set for $0.
• Need the widest cross-platform net and fine with a subscription? AI Content Shield.
• **Want to hide AI slop on YouTube and Facebook, with zero account, zero server, and nothing leaving your device?** That's the gap Unslop is built for.

Try it

If a private, local AI-content filter that covers both YouTube and Facebook sounds right, you can add Unslop to your browser for free — remove or blur AI cards, whitelist creators you trust, and watch the blocked counter climb on your own feed. The core is free forever; if it earns a spot in your browser, there's an optional one-time $5 Pro unlock (or name your price) to fund a tool that stays 100% local with no telemetry. No subscription, no pressure — install it, see if it cleans up your feed, and decide for yourself.
