Also using Mlem, here. I like it because it's a native app and has lots of customization features. I used to use Voyager, but it never quite felt native for me (though it's been a long while since I last used it).
Some say this one is fake. I'm not convinced either way. While this may not have been the "manifesto" that was found on him when he was caught, why couldn't this have been written prior to the act and the one he was caught with written after?
Several years ago, I contracted for a short time as a software engineer for a team within Walmart that was working on an in-house digital label solution. It was pretty cool as it was all custom hardware running Android. I think the project probably could've been run better, though. I'd guess that's part of the reason they have taken so long to deploy some type of digital label solution, and ultimately went with a third party product.
I'd recommend trying LM Studio (https://lmstudio.ai/). You can use it to run language models locally. It has a pretty nice UI and it's fairly easy to use.
I will say, though, that it sounds like you want to feed perhaps a large number of tokens into the model, which will require a model made for a large context length and may require a pretty beefy machine.
Also an Mlem user, here
