Peace of Mind Filter is purpose-built for addiction recovery, while Cold Turkey is a productivity timer designed for focus sessions. Cold Turkey blocks websites for set time periods on desktop only — no iOS, no Android, no image scanning, no text analysis. Peace of Mind provides always-on protection across every platform with 14 independent layers including AI image classification, 13M+ domain blocking, sexting prevention, and recovery tools like a panic button and cool-off detection.

The Fundamental Difference
Cold Turkey and Peace of Mind both block websites, but they exist in completely different categories.
Cold Turkey is a productivity tool. It blocks websites and applications for a set period of time. You start a timer — 30 minutes, 2 hours, until midnight — and the selected sites become inaccessible until the timer expires. Once the timer ends, everything is accessible again. The "Frozen Turkey" mode can lock your entire computer. It is designed to help you focus during work, not to protect you from harmful content.
Peace of Mind is an addiction recovery tool. It provides always-on content filtering that works 24 hours a day, 7 days a week. It does not have timers because protection should never expire. It scans images with AI, detects explicit text in real time, prevents sexting, and blocks 13 million domains — not temporarily, but permanently. Between blocks, Cold Turkey leaves everything accessible. Peace of Mind never stops filtering.
This distinction matters. Addiction does not operate on a schedule. A timer-based blocker assumes you know when you will be tempted. Recovery requires protection that is always there, especially at 2am when you did not plan to be struggling.
Platform Coverage
Cold Turkey is desktop only. It works on Windows and Mac. It has no mobile app — no iOS support, no Android support. Your phone is completely unprotected.
This is a critical gap. The majority of internet browsing happens on mobile devices. A desktop-only blocker leaves the most accessible, most private, most commonly-used device completely open. You can pick up your phone at any time and access anything.
Peace of Mind works on every platform: iPhone, Android, Mac, Windows, and Chrome. The same protection follows you across all your devices. There is no gap in coverage, no unprotected device sitting in your pocket.
Content Analysis vs URL Matching
Cold Turkey blocks by URL. It checks whether a website address matches its category list of "a few hundred" well-known sites. If the domain is not on the list, the content is accessible regardless of what is on the page.
This means Cold Turkey cannot detect explicit content on mixed-use platforms like Reddit, Twitter, Tumblr, or Instagram. It cannot scan images. It cannot read text on a page. It cannot catch creative misspellings or Unicode tricks in search terms. It has no awareness of what is actually being displayed — only whether the domain name matches a short list.
Peace of Mind reads the actual page. It has 14 independent protection layers:
- 13M+ domain bloom filter — instant on-device lookup covering orders of magnitude more sites than Cold Turkey's category list
- AI image classification — every image blurred by default, cleared only after a neural network confirms it is safe
- Real-time text scanning — 2,200+ terms with Unicode normalization, homoglyph detection, leetspeak conversion, and fuzzy matching
- Sexting prevention — explicit outgoing messages are stopped before leaving the browser
- Input monitoring — catches blocked words as you type, before you hit Enter
- 2,100+ blocked paths — specific NSFW subreddits, channels, and pages blocked while safe content remains accessible
- Context-aware exemptions — recovery journaling on Notion or Google Docs is never interrupted
- Network traffic interception — scans fetch, XHR, and WebSocket responses for hidden content
Cold Turkey cannot detect any of this. It has no image scanning, no text analysis, no sexting prevention, no Unicode detection, no fuzzy matching, and no awareness of page content. It is a URL blocker — nothing more.
Always-On vs Timer-Based
Cold Turkey's core mechanic is the timer. You set a block, it counts down, and when it reaches zero the protection disappears. This works for productivity — blocking Twitter during a 2-hour work session. It does not work for addiction recovery.
Recovery requires protection that never turns off. You cannot predict when urges will hit. You cannot schedule sobriety. The moments of greatest vulnerability are precisely the moments when you would never start a timer — late at night, after a bad day, during emotional distress.
Peace of Mind is always on. There is no timer to expire, no schedule to configure, no gap between "sessions." The protection is continuous. If you want to weaken any setting, there is a mandatory 3-day delay — long enough for the impulse to pass. Cold Turkey's settings can be changed the moment a timer expires.
Recovery Tools
Cold Turkey has no recovery-specific features. It is a productivity app. It does not know or care why you are blocking a website.
Peace of Mind was built for addiction recovery and includes tools designed for that purpose:
- Panic button — "I'm struggling right now" triggers a 20-minute lockdown with an urge surfing guide
- Cool-off detection — automatically detects seeking behavior and pauses browsing
- Tree tracker — visual recovery progress that grows daily (not a streak that resets to zero)
- Social media blackout — one-click, 12-hour, non-cancellable
- Tiered response — soft blocks for minor triggers, hard blocks for explicit content

Who Is Each Tool For?
Cold Turkey is designed for people who want to block distracting websites during work hours. If you need to stop checking social media during a 2-hour focus session, Cold Turkey does that well. It is a productivity timer, not a recovery tool.
Peace of Mind is designed for people in addiction recovery who need always-on protection that works across every device, scans actual content, prevents sexting, and never turns off. It understands that the problem is not distraction — it is exposure to harmful content at unpredictable moments.
A timer that expires is not protection. It is a pause. If you need continuous, intelligent content filtering for recovery — not a countdown clock for productivity — Peace of Mind is built for that.
