Testimonials
webKnossos supports almost all our connectomics work in the retina. It's the best web-based tool out there for integrated team-based annotation, proofreading, display, and output of serial EM data. The toolset is diverse, powerful, and intuitive. The functionality and ease of use just keep getting better. It has been a pleasure to work with the responsive and science-friendly folks at scalable minds.
David Berson
Professor,Brown University
We are working on systems neuroscience in the mouse olfactory bulb. webKnossos is very useful for safely storing large datasets and managing access across multiple users. It makes it simpler sharing insights with collaborators - by facilitating operations such as looking at the very same data or sharing annotations.
