Here is a quick tutorial :
1) Plug your NS4 into your computer via USB MIDI and wait until startup loading is finished.
2) Open the following link in your preferred browser:
https://ai.studio/apps/2fcdf5e5-0a2b-45 ... pplet=true
3) Accept MIDI in the browser prompt permission pop-up windows, your NS4 should be recognized by the App, if not, restart your browser.

If your Nord Stage 4 is not recognized (Firefox sometimes has MIDI issues), try using Chrome or Edge instead.
4) Choose an empty program on your NS4 by selecting the Bank and Program number in the app’s interface (for example: A11, which is a default program with the default piano selected). A midi PC message will be send to your NS4 and the NS4 will focus on the program chosen. You don't need to switch to the Program manually.
If the selected program is not empty, manually initialize all layers (=> LAYER INIT => ALL => SAVE PATCH) and save the program first, note that it doesn't matter if the default piano is active, the AI will erase it in the INIT phase.
The NS4 will automatically select the program and begin building the patch in that location.

5) Now you need to go to Nord Sound Manager => Files => Export Sound list, and import Nord Stage 4 Piano [YYYY-MM-DD] & Nord Stage 4 Samp Lib [YYYY-MM-DD], both files are html files that describes all the samples you've loaded in your NS4. The AI will be able to use the samples, even the Custom user samples, make sure to name your custom samples so the AI understand what the sample is.

6) You can now start using the app.
First, use the text box to enter a patch description, for example:
“Create a synth bass patch with a saw wave, LFO, and reverb.”

You can also target specific samples or instruments that are loaded in your NS4. For example:
“Use the Astoria Grand sample to create an ambient piano patch and add a synth pad layer with a filter LFO.”
You can also refine your request with or without using text by selecting options in the wheel, such as the instrument type and music genre. You may also choose semantic controls to make your request clearer for the AI.

You can also use the middle button 'Reset' to reset the wheel to default state.

You can also use the “Shuffle” button to reroll the Instrument Type and Genre based on the options already selected. If nothing is selected, the wheel will choose random options, allowing you to explore different styles and instruments.

8) The AI will send automatically to MIDI sequence to create the patch on the program chosen. The program will appear in the patch history on the right, you can now play on your NS4 with the new program generated, and save it on your NS4 :

You can either see the details of the patch by pressing 'DETAILS',
or press 'RECALL' send the MIDI sequence again through another Bank/Program by choosing another one, e.g Bank F Program 21 per example.
And that's it, do not hesitate to PM me if you find any bugs or things that don't work, i'm currently working in this app to make it better and easy to use !
Have fun !
