Examples

1. Highlighting Technical Terms for Documentation

Technical Writer

Background

A writer needs to ensure all instances of 'API' and 'Endpoint' are bolded in a draft to improve readability.

Problem

Manually bolding dozens of technical terms is prone to error and time-consuming.

How to use

Input the draft text, set Highlight Terms to 'API, Endpoint', choose 'Individual Words' as the type, and select 'Bold' as the format.

Outcome

The tool returns the full text with all instances of 'API' and 'Endpoint' wrapped in double asterisks.

2. Extracting Error Codes from Logs

System Administrator

Background

An admin needs to identify all 404 and 500 status codes in a large server log file.

Problem

Scanning thousands of lines manually makes it difficult to spot specific error patterns.

How to use

Paste the log content, select 'Regular Expression' as the type, enter the regex pattern for the error codes, and choose 'HTML <mark> Tag' for the format.

Outcome

The output provides the log text with all identified error codes highlighted in HTML, ready for browser-based review.
