@alexchen
Love that Secret AI actually works offline! No more worrying about my data being sent to some random server.
@jamesrod
Finally! An AI that doesn't need internet. Perfect for when I'm traveling and don't have good signal.
@sophiaw
Been using Secret AI for my journal entries. So nice knowing my personal stuff stays private. Works great even when I'm on airplane mode!
@michaelj
Got the Gemma model running on my phone. Pretty impressive speed for something that's 100% on-device!
@gracet
My go-to for brainstorming sensitive business ideas. Fast enough for daily use and actually private!
@emilyp
The photo thing is super cool. I can show it pics and it understands them without uploading anywhere. Big privacy win!

@robertw
Tried a few different models. Some are faster than others but all work without internet. Pretty cool tech!
@oliviat
I'm paranoid about privacy and this is the only AI app I trust. No data collection = happy me.
@thomasl
Been burned by "private" apps before. This one's legit - you can verify it never connects to anything. Respect.
@danielk
Connected it to my own LLM server on my home network. Works exactly as advertised. Tech nerds will love this!
@avam
I literally blocked the app's internet access in settings just to be sure. Still works perfectly! That's commitment to privacy.
@natalieb
Use this for work stuff I don't want in the cloud. No login, no account, no tracking. Just works.
