Capture a contact five ways. Tap Scan a card to photograph a paper card or an event badge, tap scan a QR code to read a digital card, tap upload to pick a photo of a card you already have, tap paste details to drop in an email signature or a LinkedIn link, or just type one in. Contact-Oh! turns any of these into a contact you can follow up on.
To have it read cards for you, add your own AI key.
Open settings (the gear) and choose Claude or OpenAI, then paste your key. Your key stays on this phone and is billed to your own account. Nobody else can see it or use it.
- Claude: get a key at console.anthropic.com. It works right away.
- OpenAI: get a key at platform.openai.com.
No key? That is fine. Type the card details in by hand and Contact-Oh! still saves and exports them, for free.
Tell it about your work. Under settings, fill in Your work, what you offer and who your ideal clients are, so the opening angle on each enriched contact fits you, not a generic pitch.
Show your own card. Fill in your details under settings, then tap the diamond at the top to show a QR anyone can scan to save you.
Your data stays with you. Captured cards live on this device. Save one straight to your phone contacts, or export them all as CSV for a spreadsheet.
Add it to your phone like an app.
- iPhone (Safari): tap the Share button, then Add to Home Screen.
- Android (Chrome): tap the three-dot menu, then Add to Home screen, or Install app.
What does the AI cost? You pay your own provider per use, billed to your key, and it is small. With Claude (Sonnet 4.6, $3 per million input and $15 per million output tokens), reading a card costs well under a US cent, and enriching a contact runs about 2 to 4 US cents, since it adds one web search at about a cent. Capturing and enriching a few hundred contacts costs only a few dollars. Prices as of June 2026; check your provider for current rates.
