Breaks the two-column reading order on the annual-report page, so headings and body text no longer follow the source navigation cleanly.

Hybrid Earnings Report
A long, real-world hybrid annual report used to benchmark end-to-end PDF-to-markdown conversion. It combines native text, financial tables, charts/graphics, and scanned signature/stamp regions, stressing preservation of document structure, reading order, and embedded visual content across a multi-section report.
Why this input is hard
- · Native digital text extraction
- · Complex financial table preservation
- · Chart and graphic retention
- · Image-based signatures and stamps
- · Reading order across a long multi-section report
- · Markdown quality and consistency

Advanced Features✓ WorkedSeparately extracts chart content into textual summaries and value tables, including a waterfall chart and bar charts with year/value pairs and growth statistics.Complex Document Handling◐ MixedHandles an 84-page hybrid report end to end, but quality degrades on signatures and multicolumn pages rather than staying uniform across the document.Table Preservation◐ MixedReconstructs the 2011–2015 financial summary table with rows and columns intact, but misses a small number of currency symbols in the extracted values.Visual Content Retention✗ FailedDoes not retain handwritten signature content as visual output on the signatures page, leaving only partial surrounding legal text and no clearly identifiable signatures.

Extend AI✓ WorkedMaintains report hierarchy and reading flow in an 84-page annual report, keeping section text, bullets, and business narrative aligned instead of flattening them.Landing AI✗ FailedFlattens a top-level page heading into plain text, losing heading semantics on a page that should read as a structured annual-report story page.LlamaParse✓ WorkedKeeps the report's heading-and-paragraph sequence intact instead of flattening the page into disconnected text blocks.Mistral AI◐ MixedHeading hierarchy is reconstructed inconsistently, so some parts of the document are flattened even though the underlying content is still recovered.Nutrient.io✓ WorkedPreserves the section hierarchy and bullet-point reading order on the sample page, keeping the 'A Growth Story Again' heading tied to its paragraph and 4 bullets in sequence.Reducto✓ WorkedLinearizes a two-column page correctly, reading the full left column, including all four bullets, before the right-column continuation appears, with no interleaving or sequence inversion.Tensorlake✓ WorkedPreserves heading order and section relationships in an 84-page hybrid annual report, keeping the narrative, bullets, and figure placement aligned with the source flow.
