I have no idea if this is blazingly fast or not but memodir is a small and simple command line utility (CLI) to remember selected directories and query them, the output can easily be piped into other commands to cd into a directory for instance.

Clone the repository, use go 1.23, go install, memodir should be ready to use!

for nix, check the nix installation guide

For a small explanation message run: memodir .help
