Built a $4.99 AI that works without internet

Cognivara AI 6 AI tools running 100% on your phone. No cloud, no subscription, no data collection.

Built for the private stuff resumes, health reports, financial docs, sensitive messages, journaling. Everything stays on your device.

Download the model once. Use it forever. Even in airplane mode.

Solo dev. No VC. No team. Just one app that does what cloud AI won't respect your privacy.

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.
