Turn figure colors back into numbers
Load a PDF or image, tell FigExtract Agents where the colorbar is, and read values out of the colors. Pick a tool:
Heatmap
One value per cell from gridded heatmaps.
- Rows and columns detected automatically
- Several heatmaps per figure, across PDF pages
- CSV matrix and per-cell diagnostics
ROI
Signal inside regions of interest drawn on images, such as IVIS luminescence.
- Ellipses, rectangles and polygons, mixed freely
- Draw once, copied into every animal's box
- Total, mean, max and signal area; optional scale bar
Map
Near-continuous images, such as spectroscopy maps and fluorescence images.
- One value per pixel, or medians over bins
- Calibrated x and y axes, linear or log
- Line profiles, ΔE and clipping flags
Everything runs in your browser; files are never uploaded, unless you run the optional heatmap agent, which sends page images to OpenRouter. Export the project (.zip) to reopen it later and review or re-run the extraction.
