Porn Blocker Rewire Brain 🧠

About

🧠 Rewire Brain — Mindful Porn Blocker

The free, open-source porn blocker for Chrome. Built on neuroscience, not shame.
On-device NSFW image classification — your data never leaves your browser.
No subscriptions. No tracking. No accounts. Ever.

═══════════════════════════════════════════════════════════════════

✦ WHAT IT BLOCKS

  ✓ 125+ adult websites (pornhub, xvideos, xnxx, redtube, onlyfans
    and 120 more) — blocked at Chrome's network layer via
    declarativeNetRequest. No DNS hijack. No proxy. No spyware.

  ✓ 30+ NSFW subreddits filtered without breaking the rest of Reddit

  ✓ On-device NSFW image blur — when explicit images slip past the URL
    filter (Twitter/X, Reddit, image search, Discord, etc.), an
    on-device machine-learning classifier blurs them permanently.
    Your images never leave your browser.

  ✓ User-added custom domains and subreddits via the settings page

✦ THE MINDFUL INTERSTITIAL

When you hit a blocked site, Rewire Brain doesn't just say "BLOCKED."
It opens a mindful pause page with:

  🌸 A rotating quote (50+ from Marcus Aurelius, Anna Lembke, Andrew
     Huberman, Thich Nhat Hanh — across 4 categories: stoic, mindfulness,
     philosophical, neuroscience)

  🫁 A 4-7-8 breathing exercise (breathe in, hold, breathe out, rest)
     synced to the visual breathing circle

  📚 Direct links to science-backed recovery resources:
     • Huberman Lab Podcast (dopamine, neuroplasticity, addiction)
     • Fortify — recovery program by Fight the New Drug
     • Anna Lembke — Dopamine Nation (Stanford addiction psychiatry)
     • Pornhub-effect peer-reviewed research

  ⏱ 30-second bypass cooldown + reflection input — friction reduces
     impulsive bypass. You can change the cooldown in settings.

✦ STREAK + PROGRESS TRACKING

  🔥 Live sobriety timer — days, hours, minutes, seconds (I Am Sober
     style) ticking every second

  🌱 Brain-tree visualization that grows from Seedling (Level 1) to
     Rewired (Level 10) as you accumulate XP
