Diff algorithm from the amazing github.com/kpdecker/jsdiff

For now, Differences are performed on text, not graphically, only the latest screenshot is available.

Screenshot requires Playwright/WebDriver enabled

This tool will extract text data from all of the watch history.

RegEx to extract

A RegEx is a pattern that identifies exactly which part inside of the text that you want to extract.

For example, to extract only the numbers from text ‐
Raw text: Temperature 5.5°C in Sydney
RegEx to extract: Temperature ([0-9\.]+)

Be sure to test your RegEx here.

Each RegEx group bracket () will be in its own column, the first column value is always the date.
