Sift: Facebook Marketplace Filter, Scam Checker, Alerts & Price History

Facebook Marketplace filter: hide ads, dealers and junk. Deal alerts, price history and scam red flags. Works on Kijiji too.

The smarter way to shop local. Sift is a Facebook Marketplace filter and scam checker for buyers, with new listing alerts and price history. It works on Kijiji too. One smart filter clears out dealers and posts you don't want. See red flags before you message, get a second opinion on the price, and get told when new matches turn up while you do something else. Free to use, with no account. Install it, open a search and Sift gets to work. ✓ Desktop notifications for new matches on the searches you watch ✓ Price history on everything you scroll past, with drop badges ✓ Fair-price check: below or above typical for your search ✓ Warning signs quoted in plain words, before you message ✓ An AI second opinion on any listing, with a fair offer and a message to send ✓ Find it used: the same thing used near you, before you buy new ✓ Hide by words, price, listing age and distance ✓ Built-in checks for cars, bikes, phones, LEGO and trading cards WHAT YOU GET: BE FIRST TO THE BEST DEALS • Deal alerts: get a desktop notification when something new matches a results page you watch, even with the tab closed. • Price history: the amounts you scroll past are saved automatically, with no Track button to press, so drops stand out. • Red flags: requests to pay first, payments that are hard to undo and off-site contact are quoted word for word. • Good deals: each item's cost is compared with the rest of the results, so bargains are easy to spot. • AI second opinion: press "Is this a good deal?" for a read on the price, a fair offer and a message to send the seller. 3 free a month. • VIN check: Sift checks a car's VIN against the ad and looks up open recalls. 1 free a month. • Find it used: on a store's product page, click Sift to see the same thing used near you on Marketplace and what you'd save. Or select a product name anywhere and right-click it. • Dealers: tag or remove businesses spotted from wording like financing, OAC and stock numbers. • Distance limit: pick how far from home you will travel, and anything farther is dimmed or cleared away. • Age and reposts: see how long something has been up, and spot relisted ones you saw before. DEAL ALERTS FOR NEW LISTINGS Get notifications for new listings without refreshing all day. Open a results or category page, press Watch in the popup, and it is checked in the background. • Free watches 1 search. Pro watches 5 and Max 25, and checks your top searches more often. • Checks are paced to keep your Facebook account safe. • Checks run while Chrome is open. Computer was off? When you're back, Sift catches up, so nothing posted in between is missed. • Quiet hours from 11 pm to 7 am and a pause while you're away from the computer are on by default, and both are easy to change. • Each search you watch keeps its own settings and location, so it only reports matches your rules would show. • One notification per search gives the count and the first two titles and what they cost. Click it to open the results. • The first run only sets a starting point, so you never get a flood of things that were already up. • Missed one? An inbox keeps matches for 30 days, with All and Unread views, and the toolbar icon shows a count. • Desktop pop-ups are optional, and you can send yourself a test one first. DROPS SINCE YOU FIRST SAW IT Your browser keeps what each item cost the first time you scrolled past it, plus each change seen after that. • Point at the Sift button or a drop badge on a card to see what it first cost, the latest changes and a small chart, plus the site's own crossed-out amount where there is one. • The drop badge shows how far it has fallen, as a percentage. • The Price tracker page lists everything that got cheaper since you saw it. Tracking starts the day you install and stays in this browser. BARGAINS AT A GLANCE The Fair price badge compares what something costs with the rest of the same results or category page and marks it Below typical or Above typical. That makes it a quick deal finder: scroll, and the underpriced ones stand out without opening each one. SPOT A SCAM BEFORE YOU MESSAGE Many Facebook Marketplace scams follow the same script. The title, the card text and the full description once you open it are read, and anything that matches these patterns is quoted: • Pay first: asks for a deposit or an e-Transfer before you see it. • Payment type: asks for Zelle, a wire, gift cards, crypto or PayPal Friends and Family. • Off-site contact: a phone number, email, WhatsApp or Telegram in the text. • Seller away: says they are out of town or leaving the country. • Ships only: offers shipping only on something people usually pick up. • Very low: priced far below similar listings. Good signs show too: one owner, service records, a receipt, the original box, a clean title or warranty left. A flag is a reason to ask questions, not proof of a scammer, so meet in a public place either way. These warnings work on English and French text. CLEAR OUT THE CLUTTER • Hide shipped items, including "Ships to you" and partner ones, with one switch. • Sold and pending items disappear from your Saved page by default. • Block words to exclude anything whose title or card says "rent to own" or "for parts", or require the words you want. Quoted phrases work, and financ* catches financing and financed. • Six starter packs in English and French, including broken or for parts, wanted, rentals and leases, and dropshipping. Each one is a single click. • Set a minimum and maximum, skip $1 and $123 placeholders and "please contact" ads, or show only free stuff. • Listed within 24 hours, 7 days or 30 days, when the site shows a posting time. • Turn off wanted posts (Wanted, ISO, WTB, Looking for), and reposts you have seen before. • Allow or block towns and neighbourhoods by name. • Smart filters can hide items or just dim them. A small counter on screen lets you peek at them or undo, and you can drag it out of the way. DISTANCE FILTER NOT WORKING? If results keep showing things far beyond the radius you picked, set your home by city or current location and choose how far you'll go. Anything farther, measured in a straight line, is removed or dimmed. SIFT PRO AND SIFT MAX Everything above is free.

QUESTIONS Is Sift free? Yes. Filters, price history, scam checks, deal alerts and Find it used are free. Sift Pro and Sift Max are optional and start with a 7-day free trial. How do I get alerts on Facebook Marketplace? Install Sift, open the results you want to follow and press Watch in the popup. It looks again while your browser is open and lets you know when something new matches. Pro and Max can send alerts to your phone. Does Facebook Marketplace show price history? Only an old crossed-out amount, and only sometimes. What you see is recorded from the day you install, and the badges and details card show what it cost before and any drop. How can I tell if a listing is fake? Look for a seller who wants money before you meet, asks for a payment you can't reverse, or moves the chat off the site. Those signs are pointed out in the seller's own words, so you can ask before you pay. Is it safe to buy on Marketplace? It can be, if you know the warning signs and meet in a safe public place. The flags above show you what to ask before you pay. How do I filter out dealers? They are tagged by default. Change Dealers from Tag to Hide, or start from the Car preset. The site's own label counts too. Why do I see items outside my radius? Results often include things beyond the distance you picked. Set a distance limit and anything farther from your home is removed or dimmed. Does it work on my phone? It runs in Chrome on a computer, not in the mobile apps. Pro and Max send alerts to your phone. Sift is a buyer's tool, not a seller tool: it never messages, posts or relists for you.
