## What is X4?

X4 turns paper business cards into organized digital contacts.

Take a photo of a business card, and X4's AI reads it for you. Name, company, job title, phone number, email, website, and address are extracted and saved automatically, so you never have to type them in by hand.

KEY FEATURES

- AI card recognition
Snap a photo and X4 extracts the details on the card in seconds, including cards in many languages.

- Company insights
X4 looks up the company's public website to help you understand who you just met.

- All your cards in one place
Browse, search, and edit your saved cards anytime. Each card keeps its original image alongside the extracted details.

- Built for global networking
Sign up with your phone number from anywhere in the world, with secure verification.
