CASE STUDY
CANADA
“The reason I chose CVAT is because whenever I had a question or an issue, I got a quick response from the team. Unlike other tools, the team behind CVAT was always listening and willing to work with me. The labeling platform is great and user-friendly, but it's the team behind it that makes the difference.”

“I love CVAT because it's so hands-on, simple and straightforward. We tried other well-known tools before, but there was a lot of friction when we tried to get them up and running, and the UI was harder to work with.”
Andre Kempe
CEO & Product Owner, ProMetronics
COMMUNITY VOICE
“We have a dedicated annotation team within our company, comprising over 50 annotators. For the past four years, we have been using self-hosted CVAT, which has been functioning exceptionally well. Recently, we acquired a project that requires annotating approximately 1 million images and videos monthly. We tried various tools, such as Supervisely, Label Studio etc, especially for video annotation, but CVAT remains the best option.”

At Dragonfly AI we help brands measure creative effectiveness of marketing materials e.g. packaging, advertisements etc. using patented AI. CVAT helps us efficiently track attention-critical areas in video ads and feed structured annotation data into our proprietary attention measurement algorithm. The platform is straightforward, reliable, and fits naturally into our workflow.

Will Champion

Customer Success Executive

We began our AI journey with CVAT because, at the time, it was the only solution truly bridging the gap between raw data capture and practical model training workflows. Years later, it continues to be a foundational part of our pipeline thanks to its robustness, flexibility, and deep alignment with real-world computer vision development needs.
