Supporting AI teams like yours

Stanford’s Division of Nephrology achieved an 80% reduction in experiment duration, while processing 3x more images with Encord’s annotation tools.



Stanford relied on three separate software tools to identify, annotate, & quantify podocytes and glomeruli in microscopy images.



Stanford adopted Encord's annotation tools & SDK to automate segmentations & measurements.



Stanford researchers decreased experiment duration from an average of 21 to 4 days, while processing 3x the images.

Encord API & SDK

Programatically access projects, datasets & labels within the platform via API.

“This was the first tool we found that could handle the enormous labeling taxonomy we had...

...we have to catalog many different types of products and Encord’s ontology feature was extremely useful in packing everything into a usable structure. The interface is also quite intuitive and the hotkeys make it easy for our team to navigate and speed up the annotation process.”

“One of the best bits of Encord are the powerful ontologies we can create...

...we can build a really complex labelling structure to cover advanced labelling requirements. Even more useful when combined with the action classification - means you can create very rich datasets to train a ML model on.”

“I can confidently say that Encord is one of the best...

...Its versatility and ever-evolving nature never cease to amaze me, allowing me to annotate objects with ease and precision… The interface is simple yet powerful and making annotation-intensive studies a breeze, especially when working with multiple objects.”
