Check the prices of products I watch and tell me what changed

It opens each product page in its own Chrome and compares prices with its last sheet, on its own computer, which you can watch. Signing up is free, with no install and no card; a dedicated cloud computer starts at $19/month with AI credits included.

Why a chat assistant alone cannot do this

A chat reply cannot open a product page, and it forgets today’s price by tomorrow. A computer with its own browser reads the live price and keeps the sheet, so next time it can tell you what moved.

How it goes

1. You give it the product links, using the prompt below.
2. It opens each page in its own browser, reads the current price and stock note and saves them with today’s date in a spreadsheet.
3. On a later run you ask it again; it compares with the saved sheet and lists what went up or down.

What you tell it

The exact prompt. The button at the bottom of this page puts it in your own chat, ready to run.

Open these product pages: <link 1>, <link 2>, <link 3>, <link 4>. Put the product name, current price and stock status into a spreadsheet with today’s date. The next time I ask, compare with this sheet and tell me what changed.

Limits, said plainly

• You start each check: it does not watch prices on its own in the background.
• A price shown only after you choose a size, color or region needs that choice named in the prompt.
• Pages that block automated visits may stop it; a CAPTCHA is yours to clear on the live screen.
