BlockNSFW – Porn & Adult Content Filter by Monolab Co.

BlockNSFW is a powerful yet lightweight browser extension that keeps your browsing safe, focused, and family-friendly. It automatically blocks pornographic and adult websites before they load — so unwanted content never reaches your screen.

Unlike simple site blockers that rely on a single list, BlockNSFW layers several detection methods that work together. It filters adult domains, understands hostnames in multiple languages, enforces SafeSearch, and now uses on-device AI to read page text and scan images — catching explicit content even when the web address gives nothing away. All of it runs locally in your browser.

🔑 Key Features
Adult Website Blocking – Blocks known pornographic domains and adult platforms before the page loads, with regularly updated blocklists.
AI Text Protection (Beta) – A tiny multilingual model reads the page's text on your device to catch adult sites in English and many other languages (Russian, Chinese, Korean, Thai, Arabic, and more).
AI Image Protection – Scans images on your device and blocks explicit ones — even when nothing in the URL is suspicious. Your images are never uploaded.
Multilingual Hostname Filtering – Detects adult hostnames in Chinese, Korean, Russian, Arabic, Thai, and transliterated Latin, including internationalized (IDN/punycode) domains.
SafeSearch Enforcement – Forces family-safe results on Google, Bing, DuckDuckGo, Yahoo, Brave, Ecosia, Qwant, AOL Search, and Presearch.
DNS Protection (optional) – Adds a network-level layer using Cloudflare for Families to stop adult domains before they resolve.
Safer Social & Video – Blocks NSFW Reddit communities, hides Facebook/Instagram Reels, and filters age-restricted YouTube content.
Stats, Streaks & Whitelist – Track what's been blocked, build streaks, manage your own allowlist, and review an activity audit — all stored locally.
Guided Setup – A simple onboarding wizard gets you protected in seconds.
Lightweight & Fast – Runs quietly in the background with minimal impact on browsing speed.

👥 Who Is It For?
Parents who want a safer browsing environment for their kids.
Students and professionals who want to stay focused and avoid distractions.
Anyone who prefers a cleaner, family-safe internet experience.

🔒 Privacy-Friendly
The AI models are bundled with the extension and run entirely on your device — no accounts, no sign-ups, and your browsing isn't tracked or sold. (Some optional features, like remote blocklist updates and DNS filtering, make network requests to provide protection; see the privacy policy for details.)

With BlockNSFW, you stay in control of what loads in your browser. Simple, effective, and built for privacy.
