[Damini2004]

Is your feature request related to a problem? Please describe.
The problem is that there's currently no easy way to determine if a word or phrase is an isogram (a word or phrase without a repeating letter) using existing tools. This can be frustrating for users who need to quickly check multiple words or phrases for isogram status.

Describe the solution you'd like
would like to have an Isogram Checker Extension that can:
Accept input in the form of words or phrases.
Analyze the input to determine if it is an isogram.
Provide immediate feedback on whether the input is an isogram or not.
Highlight the repeating characters if the input is not an isogram.

Describe alternatives you've considered
Alternatives considered include:

Manually checking each word or phrase for repeating letters, which is time-consuming and error-prone.
Using existing tools that are not specifically designed for isogram checking, resulting in less efficient processes.
