Examples

1. Blog Post Link Audit

Content Manager
Background
A content manager needs to review a Markdown blog post before publication to ensure all links are valid and not duplicated.
Problem
The post contains numerous inline and bare URLs, making manual checking inefficient and prone to errors.
How to Use
Paste the Markdown content into the input area, select 'inline' and 'bare' link types, and enable URL validation and duplicate checking.
Example Config
{"linkTypes": ["inline", "bare"], "validateUrls": true, "checkDuplicates": true}
Outcome
A JSON report listing all extracted links with their validation status and duplicates, allowing quick corrections before publishing.

2. Reference Link Consolidation

Technical Writer
Background
A technical writer is converting a Markdown user guide to another format and needs to extract all reference links for updating.
Problem
Reference links are defined separately in the document, and manually listing them is time-consuming.
How to Use
Input the Markdown file, choose 'reference' link type from the options, and sort results by URL for organization.
Example Config
{"linkTypes": ["reference"], "sortBy": "url"}
Outcome
A sorted JSON list of all reference links with their definitions, facilitating easy integration into the new format.
