Automated particle analysis
for electron microscopy
Upload TEM or SEM images and receive particle counts, coordinates,
size distributions, circularity, and density statistics.
Free tier: 3 images / month · No payment required
How it works
Three steps
Upload
Drop TEM/SEM images (TIFF, PNG, JPEG). Up to 20 MB per file. Multiple files processed in parallel.
Segment
A state-of-the-art deep learning model (BPartIS) identifies and outlines each particle instance — no manual thresholding required.
Analyse
View counts, coordinates, size distributions, circularity and 10+ more metrics. Export to CSV. Set a pixel-to-unit scale for real-world dimensions.
Computed metrics
Per-image statistics
Features
Designed for microscopy workflows
Batch processing
Upload multiple images at once. Each is analysed in parallel and results appear as they complete.
Overlay toggle
Switch between the original micrograph and the segmentation overlay to verify particle boundaries.
Unit calibration
Set a pixel-to-unit scale and convert all measurements to nm, μm, Å, pm, or other units.
Adjustable histograms
Control bin count with a slider. The histogram updates immediately.
Scalebar detection
Scalebars are detected automatically using OCR, so pixel scale is set without manual input. You can also manually set or override the scale to any value.
CSV export
Download per-particle measurements for any image as a CSV file.
