Peace of Mind Filter is a more effective content blocker than Quittr because it blocks 13M+ domains with an on-device bloom filter, pre-blurs every image with AI classification, and uses policy-installed lockdown that cannot be uninstalled. Quittr's Chrome extension has 1-2M domains with basic keyword matching that can be removed by the user at any time. Quittr also suffered a data breach exposing user data, while Peace of Mind processes everything 100% on-device.

The Fundamental Difference
Quittr and Peace of Mind both serve people in pornography addiction recovery, but they prioritize very different things.
Quittr is a recovery program with a basic content filter bolted on. Its core product is a 90-day neuroscience-based program with a panic button, AI chatbot, streak tracker, and community forum. The Chrome extension blocklist is secondary — it checks 1-2 million domains with basic keyword recognition. The extension can be uninstalled by the user at any time.
Peace of Mind is a dedicated content filter built from the ground up for depth. It has 13 million domains in an instant-lookup bloom filter, AI image classification that blurs images before they render, 2,200+ flee words with full Unicode normalization and fuzzy matching, sexting prevention that blocks explicit outgoing messages, and tamper-resistant lockdown that cannot be removed without administrator access.
The difference matters most at 2am. When willpower is gone, when the streak tracker means nothing, when the chatbot's advice feels irrelevant — what actually stops a relapse is whether the content can reach your screen. Quittr's 1-2 million domains with no tamper resistance will not stop a determined user. Peace of Mind's 13 million domains with policy-enforced lockdown will.
Filtering Depth
Quittr's Chrome extension uses a basic domain blocklist and simple keyword recognition. This approach has fundamental limitations. It cannot detect misspellings, Unicode tricks, leetspeak substitutions, or homoglyph characters. It cannot pre-blur images before they render. It cannot prevent sexting by blocking explicit outgoing messages. It cannot block specific subreddit paths while allowing safe Reddit content. And it cannot prevent a technically inclined user from simply uninstalling the extension and using Chrome without it.
Peace of Mind has 14 independent protection layers that work together:
- 13M+ domain bloom filter — instant on-device lookup, no server round-trip, 6.5x more domains than Quittr
- AI image pre-blur — every image blurred by default, cleared only after on-device neural network confirms it is safe
- 2,200+ flee words — with full Unicode normalization, homoglyph detection, leetspeak conversion, and fuzzy matching for typos
- Sexting prevention — blocks explicit outgoing messages before they leave the browser
- Input monitoring — catches blocked words as you type in any input field, before you hit Enter
- 2,100+ blocked paths — specific NSFW subreddits, channels, and pages blocked while safe content stays accessible
- Context-aware exemptions — recovery journaling on Notion or Google Docs is never interrupted
- Network interception — scans fetch, XHR, and WebSocket traffic for content hidden from the visible page
Tamper Resistance
Quittr's Chrome extension can be uninstalled by the user at any time. There is no policy enforcement, no DevTools restriction, and no protection against switching to a different browser. For anyone with basic technical knowledge — or anyone determined enough at 2am — this is not a meaningful barrier.
Peace of Mind uses policy-installed lockdown. The extension cannot be uninstalled. DevTools are disabled. Incognito mode is blocked. Guest mode is disabled. Alternative browsers are blocked. Bypass tools (VPNs, proxies, remote desktop) are blocked. And weakening any protection requires a 3-day delay — long enough for the urge to pass. This is the difference between a suggestion and a locked door.
Data Security
Quittr suffered a major security breach when a Firebase misconfiguration exposed sensitive user data. For people in addiction recovery — one of the most private struggles a person can have — a data breach is not just an inconvenience. It is a potential life-altering exposure of deeply personal information.
Peace of Mind processes everything 100% on your device. No images are uploaded. No browsing data is transmitted. No personal information is stored on any remote server. There is nothing to breach because your data never leaves your device. Your recovery stays completely private.

Recovery Philosophy
Quittr's approach is heavily gamified — streaks, badges, challenges, leaderboards. This works for motivation, but it has a fundamental problem: streak-based tracking creates shame spirals. When you lose a 90-day streak at 2am, the counter resets to zero, and that shame makes the next relapse more likely, not less. The gamification also means Quittr's business model depends on engagement with the app itself, not on you successfully staying away from content.
Peace of Mind uses a tree tracker instead of a streak counter. Your tree grows every day. If you slip, the tree loses some health — but it does not die. It does not reset to zero. You do not lose everything you built. This maps to how recovery actually works: a single slip does not erase months of progress. You are still growing.
More importantly, Peace of Mind's recovery tools sit on top of real protection. The panic button triggers a 20-minute non-cancellable lockdown while showing an urge surfing guide. It is not just a motivational feature — it physically prevents you from accessing content during the most dangerous moments. Quittr's panic button shows you your own face. Peace of Mind's panic button locks your browser.
