Contact-Oh! · For conferences and events

The card goes in your pocket. The contact goes in your phone.

Point your phone at a business card or a badge and it becomes a contact: name, title, company, email, phone, website, LinkedIn. Tag it hot, warm or cool, add a note while you still remember the conversation, and move on to the next person. Then show your own card as a QR code, and whoever scans it saves you in one tap.

  • JSON backup of everything you captured
  • Optional connection to the Client Relationship Hub

The AI part is optional

Your own key, a few cents, or no AI at all

Card reading and enrichment use your own Claude or OpenAI key. The key stays on your phone and is billed to your own account. Reading a card costs well under a US cent, and enriching a contact runs a few cents: a short brief on the company, with an opening angle written around the work you do. No key? Type the details in and skip the rest.
