does blender have "tweak" and "relax" brushes (similar to the retopoflow addon) but without addons?

i need the “tweak” and “relax” brushes like in adon::retopoflow
, for example, in the sculpt mode there is a “smoothing” brush, but it does not use “snapping face”

There’s a slide/relax tool. Does it do what you’re looking for?

If not, there is a surface option in the smooth brush that relaxes the topology while keeping the mesh shape. You juste need to find the settings that works for you under it.
