What users say
Encord is commonly used by machine learning teams that need to annotate and curate large multimodal datasets, including video, sensor streams, and text. A frequently noted strength is its enterprise-grade reliability, evidenced by adoption among organizations like Woven by Toyota and UiPath. A common limitation is that the platform's depth may be more than smaller teams require, and pricing beyond the free tier is not publicly listed.
