5 things people actually ask AI but wish no one knew

I built Cognivara AI and during testing, I noticed a pattern in what people actually use private AI for. Not the stuff you'd post on Twitter the other stuff:

  1. "Is this job offer lowballing me?" pasting offer letters into AI to decode compensation

  2. "What does my blood report mean?" too anxious to wait for the doctor's appointment

  3. "Write a message to my ex" drafting something they'll rewrite 10 times anyway

  4. "Explain this clause in my lease" scared of getting scammed but can't afford a lawyer

  5. "Am I overreacting or is this toxic?" journaling about relationships privately

These are real use cases. And every single one gets sent to cloud servers when you use ChatGPT.

That's why I built an AI that runs offline on your phone. Your words stay yours.
