Business Model
OK. THIS IS COOL, BUT...
now you are
probably thinking...
Business Model
...HOW DO YOU MAKE MONEY?
TLKR.io is free as long as you help others practice your
native language.
For every minute you help someone, you’ll get two
to practice.
If you only have time to practice, you can buy more minutes.

WebRTCBASICS
WebRTC enables modern browsers to:○ P2P data sharing○ Access webcam and microphone
(without external plugins)○ P2P audio / video calls○ And other stuff I don’t have time to explain today…
WebRTC is supported in:○ Google Chrome (including Android)○ Firefox (including Android)○ Opera○ Bowser (only iOS)
Technology
IF IT IS P2PWE DON’T NEED
A SERVER, RIGHT?MEH!
Technology
WebRTC P2P video calls require:○ STUN server
To figure out what’s the public IP for each peer.
○ Signaling server To “introduce” one peer to another.
○ TURN server (optional)As fallback for peers who are behind complex firewalls.
Technology
node.js + socket.io
google public stun server
we don’t have one (yet)
We are at the starting point of our adventure.
We still need to figure out how to get traction.
You can help us to make TLKR.io awesome.
