Peace of Mind Filter is the most comprehensive porn blocker available for Chrome in 2026. It combines 8+ independent protection layers that work simultaneously, providing deeper content filtering than any other product on the market. See all 14 protection layers.
The core layers include: a bloom filter blocking 13 million+ domains from merged community-maintained blocklists with microsecond on-device lookup, on-device AI image scanning using an InceptionV3 neural network classifying images in 50-200ms, real-time text scanning with full Unicode normalization across 200,000+ word variants including homoglyphs, leetspeak, and fuzzy matching, and outgoing message blocking that stops explicit messages before they leave your device.
Peace of Mind costs $24.99/month and works on iPhone, Android, Mac, Windows, Chrome, and Edge. One subscription covers all your devices.
Every image on every page is pre-blurred with a 40px Gaussian blur applied via CSS before anything renders. You never see an unscanned image, not even for a fraction of a second.
On-device AI (an InceptionV3 neural network) classifies each image into 5 categories in 50-200 milliseconds. Safe images are cleared and the blur is removed. Suggestive images stay permanently blurred. Explicit images trigger a full page block.
This all runs on your device using TensorFlow.js on desktop, CoreML on iPhone, and TFLite on Android. No images are uploaded to any server. Video thumbnails and background images are also scanned. The system processes images as they load and as new images appear via mutation observers, so dynamically loaded content on infinite-scroll feeds is caught as well.
Yes. This is where most filters fail, and where Peace of Mind is strongest. Unlike DNS-level filters that can only block or allow entire domains, Peace of Mind scans the actual content on these mixed-content platforms.
Instagram: Safe Mode blocks Explore and Reels. DM control lets you block all DMs or whitelist specific contacts. Profile browsing is monitored.
Reddit: Over 2,100 NSFW subreddit paths are blocked. User profile browsing is blocked by default (a common bypass to view NSFW post histories). Reddit chat and messaging paths are blocked.
Discord: Server finder and server listing sites are blocked. WebSocket traffic is scanned for blocked words.
Twitter/X: Sensitive content detection. DM blocking. Network-level content scanning catches API responses on all single-page apps.
Facebook: Messenger paths blocked. On-page content scanning active.
Yes. Peace of Mind is the only content filter that blocks outgoing messages before they leave your device. It intercepts fetch, XMLHttpRequest, and WebSocket requests in the browser. If the request body contains a blocked word, the request is stopped before it leaves your device. The server never receives it. The recipient never sees it.
This works on DMs, chat boxes, search bars, and any input field on any website. It also scans in real time as you type, so you see a warning before you even hit Send.
No other content filter does this. Most filters only monitor what you receive. Peace of Mind also monitors what you send.
Peace of Mind uses a multi-stage text normalization pipeline that generates over 200,000 word variants from 2,200+ curated base terms. Every piece of scanned text goes through the same transformations:
Homoglyph conversion — Cyrillic, Greek, and other Unicode characters that visually resemble Latin letters are converted. Leetspeak conversion — Digits and symbols are converted to letters (3 to e, $ to s, @ to a) with context-awareness to avoid false positives. Zero-width character removal — Invisible characters inserted between letters are stripped. Diacritical stripping — Accented characters normalized. Fuzzy matching — Catches missing letters, doubled characters, and adjacent swaps.
The word-split matching algorithm uses a hash map for O(1) lookups, checking all variants in under 0.05 milliseconds.
Peace of Mind is available on iPhone, Android, Chrome, and Edge. Mac and Windows desktop lockdown guides are also available for Chrome users.
iPhone — Native app with CoreML image classification, bloom filter domain blocking, and content script injection.
Android — Native app with TFLite image classification and the same filtering engine as the Chrome extension.
Chrome and Edge — Manifest V3 extension with full webRequest blocking, content scripts, and service worker coordination.
Mac — Chrome/Edge extension force-installed via enterprise config profile. DevTools disabled, incognito blocked, alternative extensions blocked.
Windows — Chrome/Edge extension force-installed via registry policies. Same lockdown as Mac.
One subscription covers all your devices.
Yes, the core filtering engine works entirely offline. The 13 million+ domain bloom filter (~37MB) is stored locally on your device. The AI image classification model (InceptionV3) runs on-device via TensorFlow.js, CoreML, or TFLite with no server calls. The 200,000+ word variant list is bundled locally.
The only features requiring an internet connection are account authentication and subscription verification, which are cached locally so the filter continues working even if you lose connectivity.
No. Peace of Mind Filter processes everything on your device. No images are uploaded to any server. No browsing data is transmitted. No browsing analytics, no content telemetry, no tracking of what you view.
We store only your account email and subscription status on Supabase infrastructure, which maintains SOC 2 Type II certification. There is no accountability partner watching your history. Peace of Mind is a filter, not a monitoring tool. Its job is to prevent you from seeing harmful content. It has no reason to collect your browsing data, and it does not.
No. Every component of the content filter runs locally on your device:
Image classification — TensorFlow.js on desktop, CoreML on iPhone, TFLite on Android. The InceptionV3 neural network model is bundled with the app. No server calls.
Text scanning — Local word lists stored on your device. Over 2,200 curated terms with full Unicode normalization, generating 200,000+ word variants including homoglyphs, leetspeak, and fuzzy matching. All processed locally.
Domain checking — A local bloom filter containing 13 million+ domains from merged community-maintained blocklists. O(1) lookup in microseconds. No DNS server queries.
The only network requests are for account authentication and subscription verification.
Yes. Peace of Mind Filter is built by SNAC AI LLC, a registered US company based in Albuquerque, New Mexico. All content filtering runs 100% on your device with zero data transmitted to external servers.
Account data is stored on Supabase, which maintains SOC 2 Type II certification. The AI image classification model (InceptionV3) is bundled locally and does not require server communication. The product is published on the Apple App Store and Google Play Store, both of which review apps for safety and policy compliance before listing.
Peace of Mind uses defense-in-depth with 8+ independent protection layers. When deployed with the lockdown guide:
The extension is force-installed via Chrome enterprise policy and cannot be removed from Chrome or Edge. DevTools are completely disabled. Incognito mode and guest mode are blocked. VPN and proxy download sites are blocked. Alternative browser downloads are blocked. Chrome policies and config profiles prevent extension removal. Tamper-resistant storage and Chrome policies prevent unauthorized changes.
Removing one layer does not disable the others. Even if someone found a way past the domain blocklist, the image scanner would still catch explicit images. Even if they somehow bypassed the image scanner, the text scanner would still detect harmful content. The layers work independently.
Peace of Mind prevents harmful content from reaching your screen. Covenant Eyes reports what you have already seen to an accountability partner. This is the fundamental difference: prevention versus monitoring. Read the full Peace of Mind vs Covenant Eyes comparison.
Image protection: Peace of Mind blurs every image by default with a 40px Gaussian pre-blur and uses on-device AI to classify before revealing. Covenant Eyes takes periodic screenshots (~1/min) and sends them in a weekly report after you have already seen the content.
Outgoing messages: Peace of Mind blocks messages before leaving your device. Covenant Eyes reports sent messages in an accountability report after sending.
Domain blocking: Peace of Mind blocks 13 million+ domains via on-device bloom filter. Covenant Eyes uses cloud-based DNS category filtering.
Privacy: Peace of Mind is 100% on-device with zero data transmitted. Covenant Eyes sends screenshots to their servers and then to an accountability partner. Your browsing history is seen by another person.
Covenant Eyes requires sharing your browsing history with another person. For many people in recovery, this creates shame and discourages honest browsing. Peace of Mind is designed for privacy.
Other filters rely on a single protection layer — usually DNS filtering or keyword matching. Peace of Mind has 8+ independent layers that work simultaneously.
Other filters can be uninstalled. Peace of Mind with the lockdown guide cannot be uninstalled without the administrator password, using Chrome enterprise policies for force-installation.
Other filters are bypassed by a VPN. Peace of Mind blocks approximately 375 VPN, proxy, and alternative browser download domains.
Other filters are bypassed by incognito mode. Peace of Mind disables incognito mode entirely via enterprise policy.
Other filters are bypassed by switching browsers. Peace of Mind blocks alternative browser downloads.
Other filters are defeated by clearing browser data. Peace of Mind persists through data clears because it is installed via enterprise policy, not stored in browser data.
Other filters miss content inside social media apps. Peace of Mind intercepts network traffic and scans API responses inside single-page applications.
Yes. Approximately 375 domains and paths are blocked, covering VPN download pages, alternative browsers, web proxies, remote desktop tools, and messaging app installers that could be used as workarounds.
Blocking is path-specific where it makes sense. For example, Brave Search remains accessible while the Brave Browser download page is blocked. Mozilla's MDN documentation is accessible while the Firefox download page is blocked. Discord's web app works while the desktop app download is blocked. GitHub is accessible for work, but specific repositories containing bypass tools are blocked.
Yes. Peace of Mind has context-aware intelligence that knows the difference between consuming harmful content and writing about your recovery.
On Notion, Google Docs, Evernote, Standard Notes, and other journaling and productivity apps, your writing is never blocked — even if you mention triggers while processing your experiences. On every other site, the same words trigger protection.
This means you can journal freely, write in therapy worksheets, and process your experiences without your filter getting in the way. No other content filter makes this distinction.
Peace of Mind includes three crisis tools designed for your hardest moments:
Panic button: Tap "I'm struggling right now" at the top of the popup. This instantly locks all browsing for 20 minutes, redirects all open tabs, and opens a dedicated page with an evidence-based urge surfing guide, a technique validated by clinical research in mindfulness-based relapse prevention. Non-cancellable.
Cool-off protection: If you hit 15 blocked pages within 15 minutes, Peace of Mind recognizes seeking behavior and automatically pauses all browsing for 20 minutes. All tabs redirect to a countdown page. Whitelisted sites like banks and email remain accessible.
Social media blackout: One tap blocks all social media platforms for 12 hours. Irreversible once activated. For those nights when you know social media is your trigger.
All lockdowns are non-cancellable and persist even if you clear browser data.
Yes. Over 40 dating platforms are blocked by default, including Tinder, Bumble, Hinge, and more.
If you decide you need access to a dating platform, the unblock request takes 3 days to activate. This impulse-resistant time delay prevents decisions driven by a moment of weakness. Re-enabling the block is instant.
Cool-off protection automatically detects seeking behavior. If you hit 15 blocked pages within 15 minutes, Peace of Mind recognizes that pattern and pauses all browsing for 20 minutes.
All open tabs redirect to a countdown page. Whitelisted sites like banks, email, and work tools remain accessible throughout the cool-off period. The cool-off cannot be cancelled or skipped.
This catches the pattern of escalating search behavior before it leads to a relapse, even when individual pages are successfully blocked.
Download Peace of Mind from the Apple App Store and follow the built-in setup guide. The native iOS app uses CoreML for on-device image classification, a bloom filter blocking 13 million+ domains, and content script injection for text scanning with full Unicode normalization.
The setup guide also walks you through Screen Time restrictions to block Safari, prevent app deletion, and disable Siri web search. With Screen Time configured, the only browser available on the device is Peace of Mind, providing complete device lockdown.
