Thanks! You can think of Grimp as a lower-level tool for interacting with the import graph in Python, while Tach is a high-level tool responsible for 'modularity' as a whole (e.g. modules, interfaces, layers, deprecations etc.)
Tach is also more opinionated - so it doesn't require you to write any custom code, and uses declarative config to enforce your desired architecture.
