## What is Bitalk?



Bitalk is a revolutionary social discovery app that helps you find and connect with like-minded people in your immediate vicinity!



Whether you're at a coffee shop, conference, concert, or just walking around town, Bitalk uses **Bluetooth Low Energy (BLE)** to create a private mesh network that connects you with interesting people nearby - all without needing internet, GPS tracking, or sharing your personal data with big tech companies!



## Why Bitalk



In our hyper-connected yet paradoxically isolated world, I believe the most meaningful connections happen **face-to-face** with people who share your interests. But how do you discover these kindred spirits in a crowded room or bustling city?

Bitalk helps you find people who have the same interests as you.



## How Bitalk Works



### 1. **Choose your topics**

Select from dozens of interesting topics or create your own! From "Bitcoin" and "Art" to "Hiking" and "Startups" - let people know what makes you tick.



### 2. **Describe yourself**

Add a quick description to help others identify you: "Guy in the yellow shirt by the coffee counter" or "Woman with the cool vintage backpack"



### 3. **Start discovering**

Bitalk automatically scans for nearby people using Bluetooth. When someone with matching interests comes within range, you'll see them appear as a bubble on your screen!



### 4. **Connect & talk**

Tap on someone's bubble to see their full profile, shared interests, and how long they've been nearby. If you vibe with their topics, approach them for a real conversation!



## Key features



### **Smart topic matching**

- **Partial matching**: "Art" matches "Digital Art", "Street Art", etc.

- **Exact matching**: Only match identical topics for more precise connections

- **Custom topics**: Create your own topics that others can discover and match with



### **Intuitive interface** 

- **Bubble visualization**: See people as floating bubbles - bigger bubbles mean they're closer!

- **Distance indicators**: "Very Close", "Close", "Far" - know exactly how near someone is

- **Real-time updates**: Watch as people move in and out of range



### **Smart notifications**

Get instant alerts when someone with matching interests enters your vicinity:

*"Found match: Nostr, Startups - alice: Woman in red jacket with many pins"*



### **Privacy & security**

- **Zero internet required** - works completely offline!

- **No GPS tracking** - only uses Bluetooth proximity

- **No personal data collection** - everything stays on your device  

- **No account required** - just pick a username and you're ready!

- **Ephemeral connections** - people disappear when they're no longer nearby

- **Hyper-local discovery** - only shows people within Bluetooth range (~30 meters)

- **Completely decentralized** - no central servers or corporate surveillance
