Launching Margin — a Chrome extension that replaces doom-scrolling news feeds with a quick side-panel check-in

Hi everyone!

Launching Margin today — a Chrome extension I built solo over the past weekend, and just shipped on Product Hunt.

The problem
I kept doing the same thing every morning: open four or five news sites, skim headlines, close most tabs without reading anything. That's not "staying informed," it's just friction with extra steps — and every one of
those sites wants me to keep scrolling, not get the headline and move on.

What Margin does
It turns Chrome's side panel into a swipeable stack of bite-sized news cards — one headline, a short summary, and a source, one story at a time. Pick your topics once, then tap through your day's news in a couple of minutes without leaving whatever page you're already on. Tap any card to read the full article at the publisher.

How it's built

• No account, no tracking, no analytics, no backend — settings and reading stats live entirely on your device
• Optional AI summaries run on-device via Chrome's built-in Summarizer — article text never reaches a server
• 25 curated topics from publishers like BBC, The Guardian, and The New York Times
• Five themes, a reading-insights dashboard, and an always-live feed on the paid tier

Pricing
Free covers 3 topics, two themes, and a 30-minute refresh — enough for casual reading. Margin Plus is $1.99/mo for unlimited topics, every theme, a live feed, and your personal reading stats.

Paid tier runs on Lemon Squeezy license keys — no subscription infrastructure I had to build
myself.

Where it's at
Live on the Chrome Web Store and just launched on Product Hunt today.

First public launch for me — would genuinely appreciate an upvote if this is useful to you, and even more so any feedback on whether the "one card at a time" reading format actually works better than a normal feed, or just feels limiting.

Happy to answer anything — about the product, the Chrome side panel API,or going the license-key route instead of full subscription billing.
