We're a startup from Poland and we created an image recognition API. It would be awesome, if you could help us with testing.
You can find our API at: www.recognize.im
An example of what you can do with it: http://www.youtube.com/watch?v=K57Q-LVE1XU
If you are interested in testing, please send me a PM via forum. I'll send you back your login and password. Please help us improve our service.
For giving us feedback everyone will the premium account (worth 29 Euro) for 30 days, also we'll have some other gifts for the most involved testers.
