AI Content Blockers Compared (2026): Clarity vs ByeAI vs AI Slop Blocker vs AI Content Shield vs Unslop

AI-generated "slop" is no longer a fringe complaint. YouTube CEO Neal Mohan has named managing AI slop and detecting deepfakes a priority for 2026 (CNBC). A late-2025 study found roughly 21% of YouTube recommendations served to new users are AI-generated slop, with an additional ~33% classified as "brainrot" (FinancialContent). Coverage of the trend notes that users are tired of the noise and increasingly ready to pay for walls, filters, and trusted human curation (TechBuzz) — Brave even added an option to block YouTube Shorts entirely as a "nuclear option" (TechBuzz).

If you want a more surgical filter than "block everything," browser extensions are the practical middle ground. Below is a straight comparison of five of them, using only their published store facts, followed by an honest "best for" verdict on each — including cases where a competitor is the better pick than ours.

The tools, one by one

Clarity

Free, around 1,000 users, and tied for the highest rating among the named free tools at 4.6, on the most ratings (9) (store listing). It works on YouTube's home, Shorts, and recommendations, uses local detection with an optional community blocklist, and keeps things simple with a single toggle and a daily counter.

Best for: YouTube-only users who want a $0, low-friction toggle and don't mind opting into a shared community blocklist for extra coverage.

ByeAI

Also free, with about 956 users and a 3.7 rating (3 ratings) (store listing). It targets YouTube and relies on community flagging / crowd-voted hiding with no account required, covering AI voice, thumbnails, scripts, deepfakes, and music. Its rating is the lowest of the group, on a small number of reviews.

Best for: YouTube users who specifically want crowd-sourced flagging across many AI signal types and are comfortable with a community-voting approach (and its current lower rating on few reviews).

AI Slop Blocker

Free, about 429 users, 4.6 rating (5 ratings) (store listing). It runs locally and, by design, blocks only videos that are self-disclosed or AI-disclosed — a conservative, low-false-positive stance. It also covers Google Search and hides Google AI Overviews.

Best for: Users who want a cautious, local filter that only hides explicitly AI-disclosed content and also want Google AI Overviews gone from Search.

AI Content Shield

The most feature-rich and the only proven monetizer in this niche. It spans roughly 20 sites — including YouTube, Facebook, TikTok, X, Instagram, Reddit, Google/Bing/DuckDuckGo, Spotify, and Gmail — using keyword filters plus a Pro tier; Facebook AI-text hiding and AI-voice blocking are Pro features. Pricing is freemium, with Pro at $6/mo or $4.95/mo billed yearly (~$59/yr) (site, pricing FAQ). Its user count and rating are not published in our data.

Best for: Multi-platform power users who want the widest coverage (TikTok, X, Instagram, Reddit, search engines, and more) and capabilities like AI-voice blocking, and who are willing to pay a subscription for them. If you live across many platforms, this is likely your best fit, not Unslop.

Unslop

Unslop hides AI-generated videos and posts on YouTube and Facebook using 100% local, on-device matching — no account, no community server, no telemetry, and only the "storage" permission. On YouTube it covers home, search, sidebar, and Shorts shelves; on Facebook it covers the main feed. Instead of crowd-voting, it matches each card's visible text against curated and user keywords, hashtags, and the platform's "Altered or synthetic content" disclosure label. Matching is whole-word, so "ai" never trips on "Dubai" or "email" — a behavior confirmed by 16 passing matcher unit tests (no false positives on Dubai/email/rain). You get custom keywords, an always-allow whitelist, remove or blur modes, and a live blocked counter (total/today). It runs on Chrome, Edge, Brave, Opera, and Arc.

Honest limits: Unslop is not first to market — Clarity, ByeAI, and AI Slop Blocker came before it and are free. It detects AI by declared signals (visible text, keywords, hashtags, the disclosure label), not by analyzing pixels or audio, so undisclosed AI with no telltale keywords can slip through. It has no AI-voice acoustic detection (something AI Content Shield Pro advertises), covers fewer platforms than AI Content Shield's ~20 sites, and deliberately offers no community blocklist (Clarity's optional shared list can catch patterns Unslop won't). We also don't publish a rating or install count yet, where competitors do.

Best for: People who want a private, fully local tool — no account, no server, no telemetry — that cleans both YouTube and Facebook in one extension. Most named free competitors here are YouTube-only, so if Facebook-feed AI is part of your problem and privacy is a hard requirement, Unslop is built for exactly that case.

A note on price (and free alternatives)

Three of the five tools — Clarity, ByeAI, and AI Slop Blocker — are completely free, which sets the baseline at $0. AI Content Shield is the price ceiling at ~$59/yr for its 20-site Pro tier. Unslop's core is free; any paid "Pro/Supporter" unlock is positioned as a one-time, optional way to fund a no-telemetry tool — not a subscription, and far below ~$59/yr.

You can also approximate AI-content filtering at $0 with do-it-yourself tooling: uBlock Origin plus community filter lists like "HUGE AI Blocklist" or "SlopBlocker," Tampermonkey/Greasemonkey custom scripts, or YouTube's native "Don't recommend channel" / "Not interested" controls. These take more setup and upkeep than an install-and-go extension, but they cost nothing — worth knowing before you pay for anything.

Bottom line

• Only use YouTube and want $0? Clarity (highest-rated free option), AI Slop Blocker (conservative, disclosure-only, plus Google AI Overviews), or ByeAI (crowd-voted flagging) all fit.
• Live across many platforms and willing to pay? AI Content Shield's ~20-site coverage and AI-voice blocking make it the strongest multi-platform pick.
• Want a private, fully local filter that also cleans Facebook? Unslop covers YouTube and the Facebook feed with no account, no server, and no telemetry — just know it keys off declared signals and keywords, not pixel/audio analysis, and isn't first to market.

The right blocker depends on which platforms you use and whether privacy or breadth matters more. Pick the one whose trade-offs match yours.
