WHY CARD NEST

Built for useful relationships, not data entry.

Your library, safely synced

Private cloud storage and offline-first foundations keep the contacts you value available when you need them.

03

AI with your own keys

Choose OpenAI or Gemini for extraction while keeping provider credentials under your control.
