How it works

How the NSFW filter works.

Every image and text block on every page passes through a multi-layer classification pipeline — cheapest and fastest checks first.

01
Domain Blocklist
Known adult domains are blocked instantly before any content loads.
<1ms
→
02
Smart Filters
Icons, logos, and UI elements are skipped. Only content images are analyzed.
<1ms
→
03
AI Image Scan
An on-device neural network classifies each image. No upload required.
10–50ms
→
04
Text Analysis
Intelligent keyword detection identifies explicit text, stories, and links.

Features

AI-powered porn blocker that works everywhere.

Install and forget. FocusShield works immediately with zero configuration.

⚡

Blur-First Design

Content is blurred before classification completes. You never see a flash of explicit content — not even for a frame.

🛡️

Works Everywhere

Not limited to known adult sites. The AI classifier detects explicit images on any webpage — social media, forums, image boards, anywhere.

🔒

Fully On-Device

The AI model runs entirely in your browser using WebAssembly. Zero images are uploaded. Zero data is transmitted.

📝

Text Detection

Catches explicit text content — stories, discussions, and links — not just images. Multi-layer keyword analysis flags and blurs text blocks.

⚙️

Configurable Strictness

Choose how aggressively content is filtered. Strict mode is built for recovery — false positives are intentional, not a bug.

🚀

Zero Setup

Install the extension. That's it. No configuration wizard. No complex setup. Protection starts immediately.

Who it's for

Safe browsing for recovery, families, and work.

Whether you need a porn blocker for personal recovery or a content filter for a shared device, FocusShield adapts to your situation.

🛡️

People in Recovery

Strict mode is built for porn addiction recovery. Aggressive filtering with intentional false positives — because one slip matters more than one over-block.

👨‍👩‍👧‍👦

Parents & Families

Add a layer of protection to shared devices. FocusShield works silently in the background with no complex parental control setup.

💼

Workplaces & Schools

Keep screens clean in professional and educational environments. On-device processing means no browsing data is sent to IT or any third party.

Privacy

Private on-device content filtering.

FocusShield was built on a simple principle: a content filter should not become a surveillance tool. All AI classification runs locally. Your browsing activity is never recorded, transmitted, or analyzed by anyone — including us.

Strictness

Your comfort level. Your rules.

Not everyone needs the same level of filtering. FocusShield adapts to you.

STRICT

Maximum Safety

Aggressively blurs anything remotely suggestive. Built for recovery and maximum safety. False positives are expected and intentional.

BALANCED

Reasonable Default

Catches clearly explicit content without over-filtering. Good middle ground for everyday browsing.

RELAXED

Minimal Filtering

Only blurs content that is unambiguously pornographic. Minimal false positives for those who want subtle protection.

FAQ

Frequently asked questions.

Is FocusShield free?

+

Yes. FocusShield is completely free to use with no premium tier, no ads, and no data collection.

Does FocusShield upload my browsing data?

+

No. All AI image classification and text analysis runs entirely on your device using WebAssembly. Nothing is uploaded, transmitted, or stored on any server.

Does FocusShield work in incognito mode?

+

Yes, if you enable it. Go to chrome://extensions, find FocusShield, and toggle "Allow in Incognito."

What sites does FocusShield work on?

+

Every site. Unlike blocklist-only tools, FocusShield uses AI to detect explicit images and text on any webpage — social media, forums, image boards, search results, and more.

Can FocusShield be used as a porn blocker?

+

Yes. FocusShield is designed to block pornographic and sexually explicit content. Strict mode is specifically built for porn addiction recovery with aggressive filtering.

Does it slow down my browsing?

+

Barely. The blocklist check takes under 1ms. AI image classification takes 10–50ms per image. Most users don't notice any difference.

Block porn and explicit content automatically.

Free, private, and fast. Install in one click and FocusShield handles the rest.
