# Footnote References

> Link footnote markers to the footnote text they qualify.

Use footnote references when the source document relies on symbols, superscripts, or numbered notes that change the meaning of the body text. Common cases include academic papers, financial reports, legal agreements, and diligence materials.

Pulse detects footnote text, finds the in-text references, and lets reviewers jump between the rendered PDF and the extracted footnote output.

```

The response includes `extensions.footnoteReferences[]`. Each item points to the footnote text bounding-box ID and the body-text IDs that reference it, so your app can render source-aware citations instead of loose text snippets.
