Ask for recommendation social media management tool

[nosuv]

Hello guys, can you recommend me a tool that can generate posts automatically. For example, we link our shop and social accounts to the tool then it can generate posts and submit the updates on my behalf. Thanks!

PS. I tried with Buffer, Viraltag, SocialFlow but none of them work with me.

haven't come across an app who can do all these! maybe not developed yet!
