Contact Sync

Ever been added to a groupchat with no one's numbers added? And then, they just all send their names spamming the groupchat with so many messages and you have to manually add the contacts one-by-one?

No longer! Contact Sync is a simple app that creates a file to add multiple contacts from manual entry, spreadsheet, or even a screenshot (uses Gemini). Note: Currently only tested on MacOS (not sure if it's possible to add multiple contacts at once on iPhone).

Tech Stack

• Framework: Next.js
• Styling: Tailwind CSS
• APIs: Gemini, AI SDK

How it works

The application allows users to add contacts individually, process spreadsheets, and even extract contact information from images. It validates phone numbers and formats them for consistency.
