Tysm for the detailed feedback !
On OmniVoice and AMD: good news, AMD is actually already supported, but only on RDNA3 (I'm on a 7800XT). It looks like what I set up for RDNA3 doesn't carry over to RDNA4, which is why the server won't start on your 9070XT. I'm fairly confident I can get it working on RDNA4 pretty quickly — it should just take a couple of back-and-forths and some testing. If you're up for helping out a bit, feel free to join the Discord server and we'll sort it out together.
On the AI response length: you can already adjust this! Open the Settings panel → AI tab → click "Show advanced options," and you'll find a Response length slider right at the bottom.
On the lore section: you can set this up today by creating a custom persona. Head to the Persona tab and edit the default "The witty historian" — copy it into a notepad, add your own lore elements, then create a new persona with that content and assign it to a new Character.
Thanks again for taking the time to write all this out — it genuinely helps me improve the app!
