Check a web page for changes and tell me what is different
It opens the page in its own Chrome and compares it with what it saved, on the clone’s 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 the page now, and it does not remember what the page said last month. A computer with its own browser saves the page text and compares it later.
How it goes
- You give it the page and what to watch for, using the prompt below.
- It opens the page in its own browser and saves the relevant text with today’s date.
- When you ask again, it opens the page, compares it with the saved version and lists the differences.
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 <page URL>, save the current wording of the section on opening hours and fees, and tell me it is saved. When I ask again, open the page and tell me exactly what changed.
Limits, said plainly
- You start each check; it does not watch the page on its own.
- Pages that change on every load, such as ads or timers, need you to name the part to compare.
- It sees what a visitor sees; a page behind a login needs you to sign in once.
What it costs
USD per month, billed by Stripe, cancel any time (effective at the end of the period). The machine runs around the clock while the plan is active. Details: pricing, credits and usage windows.
Questions people ask
Will it alert me the moment a page changes?
No. It checks when you ask and compares with the saved version.
What does it compare?
The text you name. Say which part matters so ads and counters do not count as changes.
Where is the old version kept?
On the agent’s own desktop, which persists between tasks.
