Google's "Colaboratory" is a similar use of Jupyter Notebook, but I think it's worth pointing out that Colaboratory has some added GCP-launching integrations and Sagemaker has some ML training integrations with AWS. Jupyter is open source and I wouldn't fault these companies using a familiar and quality interface for interfacing with their backend products.
