Local visual monitoring, plainly.

Creating a watch

1. Give the watch a name and paste an http or https URL.
2. The page opens in PageDog. Use it normally if you need to sign in.
3. Select the visual area that matters: a calendar, button, map, price, or status block.
4. PageDog saves the first capture as its baseline. Later checks compare that same area.

How checks work

The default interval is five minutes and the default sensitivity is Medium. Checks run locally while this Mac is awake, with small timing variation.

PageDog compares the watched area against its baseline and saves before/after evidence for meaningful changes. The watch card shows the latest check time, schedule, and visual difference.

When a page needs attention

PageDog does not bypass captchas, login prompts, bot challenges, proxies, or anti-detection systems. If a page needs a human, open it from the watch detail view, resolve the prompt yourself, then resume the watch.

What local means

Watches, browser session data, captures, comparison images, and change history stay on your computer. There is no account, cloud screenshot storage, analytics SDK, or remote monitoring worker in the v1 product.

Monitoring runs only while PageDog is open, the computer is awake, and the network is available.

What PageDog is not

It is not an AI agent, scraper platform, cloud monitoring service, captcha solver, proxy system, or Playwright workflow builder. The core promise is intentionally small: select where to watch, then see when that area changes visually.
