Converts a bar chart into a structured table, preserving the legend/value mapping but not keeping the chart as a visual chart.
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 a 12-page scanned paper end-to-end and reaches SUCCESS after extracting the page content and figure/table outputs.Reading Order & Structure✓ WorkedReflows a two-column scanned page into a single coherent reading order while preserving section-to-body flow.Table Preservation✓ WorkedPreserves the harvest-diameter table's rows and aligned columns in the extracted output.Table Preservation✗ FailedFails to faithfully reconstruct grouped headers in a multi-level stand-effects table, making parent-child column relationships ambiguous.Table Preservation✓ WorkedPreserves a nested treatment table with the 7-inch, 10-inch, 12-inch, 100-leave-tree, and clearcut columns and the acres/live-lodgepole rows.Text & OCR Completeness✓ WorkedRecovers dense readable prose from a scanned page-image source, including the section heading and multiple long paragraphs.

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.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.Nutrient.io⚠ StruggledExtracts the Figure 3 chart's values, but the chart structure and layout are not preserved, so the visualization is flattened into text-like output.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.
