Alertsie
The price you wanted. The refurb that sells out in an hour. A competitor's new sale, a launch, a headline, a listing that finally appears. Say it in a sentence. Alertsie watches the web and tells you the moment it happens.
If it is on a public page, Alertsie can watch it
Tap one to try it. Alertsie reads the page on the spot and shows you exactly what it will watch before you save.
Eight ways to watch the web
Set a target, any drop, a percent off, or a new all-time low, on any store. A price history chart on every price alert.
Get told on the first check that sees it back in stock, with the price and a link to buy.
Watch a whole page or the one box you click. AI reads the change and tells you in a sentence whether it matters.
New sales, discount codes and free-shipping offers that appear on the competitor pages you watch, with the offer written out.
New articles on any company, person or topic, filtered to the headlines you care about.
The moment a product opens for pre-order or goes on sale, so you hear about it while it is live.
A word appears or disappears: your size, a new date, "sold out", a job title.
Describe the condition in plain English. "A 4-bedroom villa under $8,000 for Christmas week." AI reads the page against it on each check.
How it works
Paste a link or type a sentence. We read the page on the spot and show you the exact price, stock status and text we will watch.
Every 5 minutes to every week, your pick. Store data is read first, then AI decides whether the change is the one you asked about.
Email, text, Slack, Discord, Microsoft Teams, webhooks or a desktop notification. Email carries the before and after, the record low and a button to the store.
Buy used, buy well
Designer bags, watches, jewelry, cameras, Macs, furniture, cars and more. For each: who authenticates, the warranty and the return window. Then one tap turns a source into an alert for new listings.
Consigners and dealers with in-house authentication and written guarantees, side by side.
Manufacturer-certified refurbished programs first, with each program's warranty and return terms shown.
Design marketplaces, enthusiast auctions and gear exchanges, with authentication and return terms side by side.
Chrome extension
On a product page it reads the price and stock and offers price, restock or launch alerts. On any other page, click the exact box to watch, or describe what you are waiting for. Alerts arrive as desktop notifications.

Plugs into your assistants
A built-in Model Context Protocol (MCP) server lets Caleyna, Claude, ChatGPT and any assistant that speaks MCP create, read, change, share and retire your alerts, and look up where to buy something used. Say "watch this for me" in the assistant you already use.

Questions
Public pages: stores, brand sites, news, listings, job boards, competitor sites. Stores that publish structured product data give the most reliable price and stock readings. When a store limits automated reads, the app says so on the spot, before you save the alert.
When a page changes, a model reads what was removed and added alongside the reason you gave for watching, and writes the one sentence you see in the alert. Store data, feeds and keyword matches run first; the model handles the judgment calls.
Yes. Every alert has a share link showing the reading, the price chart and what fired, with a button for the other person to track it too. Your email, notes and channels stay private.
Archive stops checks and keeps the full history. Delete moves the alert to Trash, where it stays restorable for 30 days.
Yes. Connect any MCP-capable assistant with your token from Settings and it can create and manage alerts in conversation.
