What are GitHub alerts?

Alerts (also called callouts) are a GFM blockquote extension introduced in July 2023. Five types — NOTE, TIP, IMPORTANT, WARNING, CAUTION — each render as a colored notice box with an icon in GitHub's UI.

Do they work in Obsidian?

Yes. Obsidian's 'callout' feature uses the same syntax, so alerts you build here work identically in Obsidian vaults.

Can I include a title?

Yes. Add a title in the form and it renders as a bold heading at the top of the callout block.

What does extract mode do?

Paste a Markdown document and extract mode walks it, finds every GFM alert, and shows you the type, title, body, and line number for each one.
