BlockNSFW – Porn & Adult Content Blocker

BlockNSFW is a lightweight browser extension that keeps your browsing safe, focused, and family-friendly. It stops pornographic websites before they load, so unwanted content never reaches your screen. Unlike simple site blockers that rely on one list, BlockNSFW layers several checks that work together: a large database of adult domains, hostname checks in many languages, SafeSearch, and on-device AI that reads page text and looks at images, catching explicit content even when the web address gives nothing away. All of it runs locally. Version 2.0 is built for the hard moment: not only closing the door, but helping with the pull, the pause, and the choice you make. 🔑 Key Features Website Filtering – Stops 237,000+ known adult domains before they load, updated regularly. AI Text Protection (Beta) – A small model reads the text on your device to catch what slips past. It reads English and most European languages best. AI Image Protection (optional) – Checks images on your device and hides explicit ones. Your images are never uploaded. Multilingual Hostname Checks – Recognizes explicit hostnames in many languages and scripts, including internationalized domains. SafeSearch Enforcement – Keeps results family-friendly on the major search engines, and turns on YouTube Restricted Mode. DNS Filtering (optional) – Adds a network-level layer through a family-friendly resolver you choose, or your own. Safer Social – Filters NSFW Reddit communities and can hide Facebook and Instagram Reels. Follow Other Lists – Subscribe to ones other people maintain. They can only ever add to what's filtered. PIN Lock – Put a PIN over the settings that would weaken your defenses. It's stored as a salted hash. Stats & Days Kept – See what was stopped, count the days you kept, manage your allowlist, and review an activity log, all kept locally. Light & Dark – A calm, paper-and-ink design. It starts light; switch to dark or follow your computer. Guided Setup – A short onboarding wizard sets you up in seconds. ✨ New in 2.0: Built for the Hard Moment Gateways – Name the sites where it tends to start. Opening one asks you to pause first, from 5 to 60 seconds, and in your hard hours they stay closed. The Pact – Choose a wait, from 15 minutes to 3 days. Any change that loosens your settings waits it out, even with your PIN. Making them stronger never waits. A Friend Holds the Key – Someone you trust keeps a code in an authenticator app. Only that code lets a change through early, and they never see your browsing. Storm Mode & Risk Hours – For a hard few hours, or the same hours every night, every layer goes to its strongest and nothing can be loosened until it ends. Your Own Words – Your plan, a note to yourself, and someone to call, written on a good day and shown first when a site is held. Held at the Door – When a site is held, BlockNSFW now says why: six layers, drawn as six doors, and the one that stopped it. After a Slip – A short, plain note for the morning after. A slip costs one day, never your progress. Your Week – Every Sunday evening, your week read back, day by day. Back Up & Restore – Save everything in one file, and bring it to a new computer. 👥 Who Is It For? People working to quit porn, who want something that holds on the hard nights. Parents who want a safer internet for their kids. Students and professionals who want to stay focused. 🔒 Privacy-Friendly The AI runs entirely on your device: no accounts, no sign-ups, and your browsing isn't tracked or sold. Optional features, like database updates, DNS filtering, and checking a Supporter code, make network requests; see the privacy policy for details. 💚 Supporter (Optional) Every feature above is free, and stays free. If you'd like to go further, and help keep BlockNSFW going, Supporter adds the full 30-day path, an evening check-in, a letter every month, a message in your own voice for the hard moment, your progress on every computer, and more designs. $4.99 a month, $29.99 a year, or $89.99 once.
