Emits semantic attestation blocks for handwritten-signature regions and a blurry signature stamp, distinguishing the signer/company name and the signature legibility instead of leaving those regions unannotated.

context, not decisivetransformation
Separate extraction modes and OCR confidence flags are useful workflow features, but they do not by themselves determine whether the Markdown conversion is good. (3 of 3 judges)

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
Output — unretouched



Also checked on this input — same tool, 5 other criteria
Reading Order & Structure✗ 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.Reading Order & Structure✓ WorkedPreserves reading order on a narrative annual-report page by keeping the page title, embedded photo description, paragraphs, and financial-highlights table in sequence.Reading Order & Structure✓ WorkedPreserves section flow and heading-to-body relationships in a scanned report section, keeping the '19. Commitments and Contingencies' heading and the 'Data Breach' subsection attached to the following paragraphs.Table Preservation✓ WorkedReconstructs a five-year financial results table with the 2015–2011 columns and aligned row/value relationships intact in markdown-style rows.Visual Content Retention✗ FailedReplaces a waterfall chart with text, preserving the SG&A rate values and year-to-year change labels but not the chart as a visual asset in the output.

Reducto✓ WorkedThe separate schema-driven extract.run endpoint cleanly recovers both a financial table and a donut chart: all requested table rows and all five donut percentages come back exactly.Tensorlake✓ WorkedProvides separate chart extraction for the SG&A waterfall, outputting chart metadata with a title, axis labels, 10 category labels, and a numeric series instead of only inline prose.Upstage AI✓ WorkedSeparately extracts chart content into textual summaries and value tables, including a waterfall chart and bar charts with year/value pairs and growth statistics.
