Auto Tweet Bot

hello. im curious about an auto tweet tool because ive seen accounts that auto reply to hashtags tweeted
so if i tweet #iphone some account would tweet me with their website related to an iphone. i would like to know if anybody has any idea of this

there are alot of bots around here , just use the search bar , i once use a bot called Tweetadder
not sure if its still work TBH

There are so many bots here. I'd link them to u but my I'm not allowed. Also the good ones that work perfect are not free just to let you know
