Yes. It tries to fit your route to known cycle routes based on the open bikefiets cycle maps.
In general you enter the start and end points and see what it suggests.
Ity can be overly cautious as it will try to avoid major roads at all costs, but sometimes you might be happy enough to ride on a major road for a few miles rather than through unknown sidestreets for 2-3x as far. You can click on a road and open in it Streetview, or see if there are geotagged images from the same location.
For finding what a bridleway looks like, this latter feature is excellent.
Where it does fall down is that it will not route you onto one-way footpaths. So if there is no exit, it won't let you go there, even though it's obvious it's a real route (these paths are usually there because the open streetmap data is incomplete). So sometimes you end up creating routes that don't properly work and have to import them into Kommute or something to close the links. Usually I make notes and memorise the route.
I've found some amazing routes and trails beciuase of it and that includes a lot of "hidden" infrastructure that looks dodgy as fuck on a map, but turns out to be excellent.
