Linux power users organically found this. One-click sidebar extracts clean text across 12+ sites using Mozilla engine. v1.0.1 just dropped with pro features.

Curious what HN Linux folks think of UX/performance.

I built VEIL, a Chrome extension that automatically classifies the site you're on and applies context-appropriate privacy protection.

The problem I was solving: most tracker blockers apply identical rules everywhere. But a banking site warrants much stricter protection than a social media site — different threats, different tradeoffs between privacy and functionality.

VEIL detects four contexts: - Financial — maximum blocking, WebRTC leak protection, strict fingerprint masking - Shopping — affiliate tracker blocking, price manipulation protection - Social — balanced blocking that keeps sites functional - Work — corporate tracker blocking, identity compartmentalisation

No configuration needed. Works from install.

Six months in, growing purely organically at ~234% week-on-week, 52 installs, zero uninstalls three periods running.

Happy to discuss the technical approach to context detection or any aspect of the implementation.

Good morning!

I'm a solo UX designer from London, and I built Dopamine Detox to solve my own problem: losing 3+ hours a day to mindless scrolling.

What it does: - Tracks time on TikTok, Instagram, YouTube, Twitter, Facebook in real-time - One-click blocking (30/60/120 min sessions) - AI predictions warn you BEFORE you fall into a binge (premium) - Build focus streaks with gamified rewards - 100% privacy-first – all data stored locally, never leaves your device

Technical stack: - Chrome Extension Manifest V3 - Vanilla JS (no frameworks – keeping it lightweight) - Local storage only (no backend, no servers, no data collection) - Dynamic site tracking with content scripts - Declarative net request API for blocking

Early results (2 weeks live): - 56 installs from 85 page views (65.9% conversion rate) - 12 weekly active users (89% retention) - 58% of users are on ChromeOS (Chromebook students love it!) - 0 uninstalls in last week

The most interesting technical challenge was building AI predictions without sending data to a server. I use on-device pattern recognition to predict when you're about to waste time based on your historical behavior.

Pricing: Free forever (5 sites), $19.99 one-time for premium (no subscription).

Would love feedback from the HN community – especially on: 1. Privacy approach (is local-only storage compelling enough?) 2. Pricing ($19.99 one-time vs subscription) 3. Features you'd want to see 4. Technical implementation suggestions

Happy to answer any questions about the build process, challenges, or anything else!

I built CycleSync after noticing there's no lightweight, privacy-first cycle tracker that lives in your browser without requiring an app download or account signup.

It tracks your cycle phase, predicts your next period and ovulation, lets you log symptoms daily, and gives you phase-specific tips (e.g. peak energy during ovulation = good time for big meetings). No account needed. All data stays local in your browser.

Would love feedback from the HN community — especially on the UX and what features would make this actually useful day-to-day.

I got fed up with reading online. Every article I open comes wrapped in cookie banners, autoplaying videos, sidebar ads, and subscribe popups. Chrome has a built-in reader mode but it only works on a handful of sites and has zero customisation. Firefox's is better but I'm a Chrome user.

So I built READR — a Chrome extension that strips any webpage down to just the content.

The core is Mozilla's Readability.js (the same library behind Firefox Reader View), so coverage is broad. It handles Medium, Substack, Wikipedia, news sites, research papers, most blogs. When Readability fails it falls back to a paragraph-density heuristic.

It runs entirely in the browser. No server, no telemetry, no account required. Settings sync via Chrome's storage.sync API. The extension has four permissions: activeTab, scripting, storage, tabs — nothing broader.

Free features: reader overlay, dark/light theme, font size, line width control, ESC to close.

Pro ($19.99 one-time, no subscription): PDF export via window.print() with a print stylesheet that isolates the overlay, and auto-open on domains you specify.

Built with vanilla JS, no framework. The whole extension minus Readability.js is under 600 lines.

Interested in feedback on: sites where extraction fails badly, whether the Pro features are the right ones to charge for, and whether $19.99 one-time feels right or too high/low.

Tracking solved my 2h15m YouTube binges:

Dopamine Detox shows exact time per site live in Chrome AI warnings before patterns repeat Blocks with one click

Day 1 launch: 200 installs already

Dopamine Detox Chrome extension solved this for me:

Real-time tracking → "YouTube: 2h15m today" shame dashboard AI predicts binges → " 2h risk today" 1-click blocks → focus mode

Mentoring designers fixed their biggest blocker.
