@robertw

Tried a few different models. Some are faster than others but all work without internet. Pretty cool tech!

Olivia Thompson

@oliviat

I'm paranoid about privacy and this is the only AI app I trust. No data collection = happy me.

Thomas Lee

@thomasl

Been burned by "private" apps before. This one's legit - you can verify it never connects to anything. Respect.

Daniel Kim

@danielk

Connected it to my own LLM server on my home network. Works exactly as advertised. Tech nerds will love this!

Ava Martinez

@avam

I literally blocked the app's internet access in settings just to be sure. Still works perfectly! That's commitment to privacy.

Natalie Brown

@natalieb

Use this for work stuff I don't want in the cloud. No login, no account, no tracking. Just works.
