Extracts the Figure 3 chart's values, but the chart structure and layout are not preserved, so the visualization is flattened into text-like output.
What was measured
Visual Content Retention
Retains charts, figures, diagrams, and images in the output and places them in the correct reading position.
decisive for this rankingtransformation
For complex PDFs, figures, charts, and images are part of the document content, so preserving them in the right place is part of the core job. (3 of 3 judges)
What was given, what came back
Test input: Scanned Research Paper · pdf · group: scanned-research-paper
Input — what we sent
An image-only scanned research paper used to stress OCR and layout recovery in a multi-column academic document with figures, charts, tables, captions, and references.
Why this input is hard
- · OCR on scanned pages
- · Multi-column reading order
- · Figure and chart handling
- · Table reconstruction from scans
- · Caption association
- · Reference extraction
- · Overall document structure retention
Output — unretouched

Complex Document Handling✓ WorkedProcesses an image-only scanned research paper end to end and returns a parsed markdown output plus preview, showing it can handle a multi-page scanned document.Reading Order & Structure✗ FailedMisorders the first page so the abstract is placed before the title, showing a layout-reading-order inversion on the scanned article.Reading Order & Structure✓ WorkedThe tool preserves section hierarchy and column order in a dense multi-column scanned section, keeping headings aligned with the correct body text.Table Preservation✓ WorkedLargely preserves grouped-column tables, keeping their internal organization intact in the extracted output.Table Preservation✗ FailedBreaks more complex multi-level tables, with rows and merged cells misaligned or lost once the hierarchy becomes dense.Text & OCR Completeness✓ WorkedRecovers readable text from scanned pages, including the abstract, keywords, author affiliations, title, and opening paragraphs on the first page.

measured on Visual Content Retention
Adobe API✓ WorkedKeeps chart artwork embedded in the extracted page, placing the residual basal-area figure in situ beneath the extracted table text.Extend AI◐ MixedExtracts chart values into a captioned figure block, but the report says the mortality chart's trend visualization is not fully retained.Landing AI✗ FailedConverts a scanned bar chart into a textual transcription of legend items and approximate values instead of retaining the chart visually in the output.LlamaParse◐ MixedConverts a bar chart into a structured table, preserving the legend/value mapping but not keeping the chart as a visual chart.Mistral AI✓ WorkedCharts are exposed through both page-wise markdown files and the extracted visual assets, keeping the visual content linked to its original document location.Reducto✓ WorkedSegments a shield logo out of a single full-page raster scan and also retains Figure 1 as an image with an accurate synthesized caption; the returned logo crop is a tight 77x81px cut with legible shield text.
