The CAPI-DETECT study examined 1,780 capillaroscopies and developed a machine-learning approach using 24 quantitative variables. Its methods, observer-consensus criteria and validation results are available in the peer-reviewed paper.
The paper details the evaluated algorithm, study population and validation methods.
Open the images, move between fingers and inspect the measurements in our embedded viewer. This is an educational example of an active scleroderma pattern, available without an account.
Example for education and software evaluation. It is not a diagnostic service.
No special hardware required: Capillary.io works with your capillaroscope, USB microscope, or standard optical microscope.
For Dino-Lite, Inspectis, Smart G-Scope, Optilia, and many USB microscopes, Capillary.io CapillaryScope gives you one coherent desktop app for direct capture, calibration support, and direct upload to Capillary.io.
Our AI analyzes each image instantly: the app automatically detects and labels capillaries and hemorrhages in every image.
Standardize analysis, reduce variability, and spend more time on expert review. Consistent, immediate results, ready to review.
Invite your team, share protocols, and review studies together from anywhere.
With Capillary.io you can launch and coordinate research projects in an organized, professional way, with standardized metrics and reports ready for review and audit.
A powerful user interface to visualize your images
Our application is specially built for visualizing and analyzing nailfold capillaroscopy images. Besides marking capillaries, you will also be able to measure them, adjust the image view with filters, or let our algorithm do the analysis for you.
Access your Cloud data from anywhere
You will no longer need to send images by email or have your pendrive with you all the time, our application allows you to access them from any online device, whether it's a computer, a tablet or a smartphone.
Collaborate with other professionals
Conducting studies with hundreds of images will become much faster and easier using our application. You will be able to comment images with other people, validate them and agree on each capillary, but also view the activity in each image by you and your teammates at any moment.
Automatic reports
Download structured reports about each study with a single click, with quantitative and qualitative information. The software follows standardized EULAR/ACR criteria for nailfold capillaroscopy.
Information security and privacy for capillaroscopy image capture, storage, reporting, data export, and MFA-protected access for clinics and research teams.ISO 27001
Our platform is certified with ISO/IEC 27001 information security management standard.
GDPR Compliant
GDPR-first for capillaroscopy data: consent, minimisation & pseudonymisation, access logging, and easy export/erasure.
We collaborate with leading centers in microvascular research. Our AI-driven advances in capillaroscopy have been published in high-impact journals such as Rheumatology (Oxford) and Clinical and Experimental Rheumatology.

How to save time time while performing nailfold capillaroscopy - A diagnostic tool
Replace manual image handling with a process built for capillaroscopy.
Images spread across local folders, screenshots, USB drives, and emails.
Manual reports that are slow to repeat and hard to compare.
Little structure for follow-up, teaching cases, exports, or research datasets.
Structured cases with images, fingers, visits, AI-assisted findings, and quality review.
Automatic reports that can be exported and shared when you need them.
Organized projects for follow-up, collaboration, teaching and research.
Start free with 10 images per month. Upload a first image, generate a report, and explore the complete workflow.
