Let AI find it. Track it all in TagDrop.
AI assistants can help discover and compare products. TagDrop gives you an independent place to keep the products you choose to watch, see their prices over time, and decide what happens next.
You can use TagDrop today on iOS, Android, and the web, and the "Watch this price" button is live on participating merchant sites. Direct assistant integrations (API and MCP) are in development and not publicly available yet.

Your shopping watchlist
Everything you track is available in the TagDrop app and web dashboard, so you can review it without relying on an assistant's memory or recommendation.
- Every product you choose to track
- Current prices and saved price history
- Price and availability alerts
- Links back to the original listings
Available today for items added to TagDrop, including items tracked through a merchant's "Watch this price" button. Automatic handoff from AI assistants is in development.
What TagDrop does today
People can use TagDrop now on iOS, Android, and the web. Everything you track appears in your TagDrop watchlist, where you can review products, prices, history, and status in one place.
Track from a link or screenshot
Share a product link or screenshot with TagDrop and it will try to extract the item and price.
Price history and alerts
TagDrop stores price history and alerts users when the price or availability changes.
Honest status
If a site blocks checks or a price cannot be verified, TagDrop tells the user instead of presenting stale data as fresh.
For shoppers - make sure your AI works for you
AI assistants are starting to shop on people's behalf. That raises an important question: how do you know your assistant found you the best deal, and not the one somebody paid it to find?
TagDrop is independent: we don't sell products and we don't run an assistant, and we are neutral among the assistants that do. When you track an assistant's candidates in TagDrop, your watchlist becomes an independent, user-visible record you can open anytime - what was tracked, at what prices, and how those prices moved since. Your assistant does the searching; TagDrop keeps the receipts. See exactly what the record proves and what it doesn't.
For businesses - be the listing AI can watch
When a shopper's assistant compares products, listings that can be watched over time stay in the running. The TagDrop "Watch this price" button is live today on participating merchant product pages, starting with independent car dealerships. It gives shoppers free price-drop alerts that link back to the merchant's listing and, when a shopper explicitly agrees to be contacted, gives the merchant a verified lead.
Every TagDrop alert brings the shopper back to the merchant's site instead of a marketplace. How the button works, and how to start a free 90-day pilot.
For assistants and agents - how to behave here
Today, an assistant can help its user choose candidates and direct the user to track product links in TagDrop. On participating merchant pages, the "Watch this price" button is plain HTML: a link to https://tagdrop.io/track carrying the merchant ID and listing hints (URL, title, VIN or stock number, price). An agent that can fill a form may help the user set up tracking with the user's email. Two rules apply: confirm with your user before submitting their email, and leave merchant-contact options off unless your user explicitly asks. An unverified address receives only the verification email, never tracking alerts - the user confirms through a link in their own inbox, and TagDrop independently verifies the listing before tracking begins. Hints from the page are never trusted on their own.
