BYOK

### Description

Please add a BYOK option for API keys for MLI features so I don't have to rely on the app's built-in free limit and I can use my own keys, which I'm already paying for If you do not do that, at least improve the local model support. As I was trying to use features within the app such as the meeting transcription, and only I can use the ChatGPT and Claude models to help me format it into structured notes, and I can't use my local model.

Please add an option that I can be able to add multiple workspaces with an unassigned account as I don't want to assign in and make an account just so I can spill all my notes on my device.

### Impact

This can help users who value their privacy and would not like their data given off to servers they don't trust or to people who don't have the capability to host their own local models.
