MedSeg

MedSeg is an AI-assisted medical image segmentation platform built by radiologists.

  The free single-user version is still at medseg.ai. The new multi-user workspace at app.medseg.ai is built on the same segmentation engine and adds:

  • A library of pre-built AI models for CT and MRI: TotalSegmentator, MRSegmentator, FastSurfer, MindGlide, TissUNet, Viola-Unet, BodySegAI, plus a specialty pack for epilepsy work.

  • nnInteractive for universal 3-D interactive segmentation on any modality, with click, scribble, freehand, or bounding-box input.

  • Custom model training: bring your own masks, train an nnU-Net on your data (2-D or 3-D), with optional transfer learning.

  • A built-in chat assistant that can run any of the above on demand, summarise series, list jobs, and answer how-to questions.

  • Cloud-hosted GPU compute, with DICOM and NIfTI throughout.

  Free for research. Try the new workspace at app.medseg.ai.
