I have not formally published it, but it's open source: https://github.com/edmistond/larmindon and https://github.com/edmistond/larmindon-core - you'll want to clone them into the same root directory.

Right now it only supports languages supported by parakeet-rs and Nemotron (so... English only as far as I'm aware) and you'll need the ONNX version of Nemotron: https://huggingface.co/altunenes/parakeet-rs/tree/main/nemot...

The first run experience isn't great, you'll need to download all the files from the model, start the app, and then go to settings and configure the model directory. It runs well on Mac and Windows; I haven't tested it on Linux in a couple of months since my Linux install is out of commission currently.
