[Help] Is there anything such as this? (Please help)

Hello,

I'm having hard times finding the correct counter for heroes in the game as the time is also less, it totally confuses me leading me to pick a very fragile hero.

I'd like to know if there is ANY website like DotaZerk BUT for DotA 1 not 2 that shows heroes and counters OR is there any tool such as this where you input 1-5 heroes and then the tool tells you the best possible hero which can counter them and the weakest hero which will be countered.

Please help, I need it.
