Produces usable but not clean markdown: the output contains 12 <signature> tags, 2 <empty> placeholders, and literal HTML tags such as <b>, <i>, and <u> instead of pure CommonMark.
What was measured
Markdown Quality
Produces clean, well-structured, usable markdown rather than a flat text dump.

Input — what we sent
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

Advanced Features✗ FailedOn the bar-chart schema, extract.run gets only 3 of 5 Sales values right: 2011 and 2012 are silently pulled from a different table ($69.9B and $73.3B), with no confidence or warning signal.Advanced Features◐ MixedThe parse pipeline’s confidence field catches all 10 footer-number corruptions and also produces one false alarm on a correct securities table, so the signal is real but not perfectly calibrated.Advanced Features✓ 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.Complex Document Handling◐ MixedProcesses the full 84-page mixed-content report in 25.5 seconds with no truncation and keeps the hardest nested table’s 27 values exact, but 10 footer numbers are corrupted in the back two-thirds of the file.Reading Order & Structure✓ 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.Reading Order & Structure⚠ StruggledDrops heading structure on most of the filing: the FORM 10-K opening area receives no # or ## markup, and the report says 80 of 84 pages stay as plain paragraphs rather than navigable section headings.Table Preservation✓ WorkedPreserves a genuinely row-paired 52-row state table as a clean grid, keeping the 1,792 stores total and 239,539 retail-square-footage total intact.Table Preservation✗ FailedMis-merges two independent side-by-side lists into one table, forcing unrelated cost-of-sales and SG&A bullets into fake row pairs where no row correspondence exists in the source.Text & OCR Completeness✓ WorkedConverts the full 84-page native-digital annual report with no skipped pages; the output contains all 84 page-marker pairs, and checked high-risk numbers survive exactly, including the $51,550,988,273 market-value figure and 599,982,121 shares outstanding.Visual Content Retention✓ WorkedRetains visual content as real image outputs when requested: the portrait, donut chart, and bar chart are all returned as preserved figure/image crops rather than being dropped.Visual Content Retention✗ FailedDoes not retain handwritten signature graphics as images: a signature crop returns only the <signature> placeholder plus the printed name/title, omitting the cursive mark itself.

Mistral AI✓ WorkedThe export is usable markdown rather than a flat text dump: it includes an overall markdown file plus page-wise markdown files delivered in a downloadable ZIP.PDF.ai✗ FailedMarkdown export failed on an 84-page hybrid earnings report; the report records "Output MD: Output failed."PDFVector◐ MixedReturned markdown-like content inside JSON, but the document structure was largely flattened rather than preserved as faithful markdown.Tensorlake✓ WorkedRenders the extraction as structured, copyable markdown in the Document Markdown view rather than a flat text dump.
