BlockP is a porn blocker that uses on-device AI to detect and block explicit content in real time — across browsers, apps, and social media feeds.
How the AI works
Most porn blockers maintain a list of known adult domains and block access to those URLs. BlockP uses a different approach: an AI model analyses visual content directly on your device and blocks explicit material regardless of the domain it appears on. This means BlockP blocks adult content on platforms that URL-list blockers cannot reach — including image search results, social media posts, and video thumbnails.
What BlockP blocks
— Adult websites and explicit domains — blocked at both the network level (VPN) and the content level (AI)
— Explicit images and video thumbnails detected in browsers, YouTube, Reddit, Instagram, and other apps
— Keyword-triggered content — configurable list of terms that trigger a block when detected on screen
— Newly installed browsers and apps — auto-detected and blocked to prevent bypass attempts
— Search engine adult results — SafeSearch enforced on Google, Bing, DuckDuckGo, and YouTube
Accountability features
— Partner notification — a designated contact receives an alert if the app is uninstalled
— Password protection — settings changes require approval from the accountability partner
— TimeDelay — a configurable delay is applied before any setting can be modified, preventing impulsive changes

Focus and productivity tools
— App blocker — block individual apps (YouTube, Instagram, Telegram, or others) on a schedule or immediately
— Focus Mode — during active sessions, only user-selected apps are permitted; all others are blocked
— Custom redirects — blocked pages can redirect to a URL of your choice
Free and Premium tiers
The free tier includes AI content blocking, website and app blocking, SafeSearch enforcement, and partner notifications. Premium adds Advanced Focus Mode, TimeDelay accountability, and priority support.
Data and privacy
AI content analysis runs entirely on-device. No screen content, browsing history, or detection events are transmitted to external servers. Permissions used by BlockP:
— Accessibility Service — detects and blocks content across browsers and apps in real time
— VPN Service (optional) — network-level filtering to block domains across all browsers, including private browsing modes
— System Alert Window — displays the block overlay when restricted content is detected
— Device Administrator — prevents uninstallation without accountability partner approval
Intended use cases
— Adults managing personal internet use and seeking a reliable porn blocker
— Individuals on a NoPorn programme requiring tamper-resistant blocking
— Parents configuring a porn blocker and parental control solution on a child's device
— Individuals seeking an app blocker and focus tool for study or work productivity
BlockP is available free of charge. Optional Premium features are available via subscription. More information at blockp.io.
