Sieve
Clean Internet Suite — a privacy-first browser extension that quietly cleans up the modern web.
Sieve blocks the stuff that makes the internet feel hostile — scams, gambling,
dark patterns, toxic comments, popup hijacks, and endless feeds — and gives you
back a bit of control. It runs entirely on your device: no account, no
tracking, nothing leaves your browser.
Honestly, I made this because I got tired. The internet I grew up on felt fun
and open. Somewhere over the years it turned into scams, nasty comments,
endless feeds, and sites that trick you at every click. So I built the tool I
wished existed. — monolab
Features
On-page cleanup
- Bad Language Filter — masks profanity on pages (funny or family-safe styles, plus your own word list).
- Toxic Comment Hider — collapses toxic comments on YouTube, Reddit, X/Twitter, and Disqus, with an optional on-device TensorFlow.js toxicity model.
- Dark Pattern Blocker — catches fake countdown timers, guilt-trip copy, pre-checked boxes, and manufactured scarcity, and shows you what it found: the toolbar popup lists what each page tried and what Sieve did about it, with Show me and Undo, and the toolbar badge counts the tricks. It remembers what a page claimed (for 30 days, on your device, under scrambled codes rather than addresses) so it can prove a fake: a countdown that restarts when you come back, an "only 3 left" that never moves or jumps about, a sale that "ends today" every day, a "23 people are viewing this" that says 23 every time. It also hides "Sarah from Ohio just bought this" pop-ups, found by their shape rather than by who sells the widget. How firmly it responds is your choice — Gentle only labels, Balanced fixes what's likely and covers what's proven, Firm covers anything likely — and whatever you pick, something it isn't sure about is only ever labelled. It also reads the small print on free trials that turn into payments — "After 7 days, this becomes $14.99 a month; the first payment is due Thu, Oct 15" — and offers to remind you two days before, on your device, with no account, email or notification permission: the reminder appears at the top of whatever page you're on that day.
- Cookie Auto-Reject — automatically rejects cookie-consent banners (built on the MIT-licensed Consent-O-Matic rules).
- Popup & Click Hijack Blocker — blocks popups and click-hijacks by default, with a per-site allow prompt and whitelist.
- Search Result Filter — opt-in sorting of your search results before you click: colour-code the sources you trust and hide the ones you don't, each rule carrying its own colour. Works on Google, Bing, DuckDuckGo, Brave Search, Yahoo and Swisscows. Hidden results are counted with a link to show them, never dropped silently, and every affected result can tell you which rule changed it and where that rule came from.
