The best bot I have found here is Hive account@ginabot.

I wrote a review of it for Blindtest here:
https://steemit.com/busy/@fitinfun/blindtest-ginabot-21-days

I have a ton of detail in the review, so please read it if you are interested in trying it.

Basically:

• you join the discord
• you set it up to say what you want to be notified about
• you get notifications for those things in discord.

It has really helped me work here on steem in the few weeks I have had it. I wanted it to see when I got mentioned, but now I have so much more information. I do not have to check for things and just look in discord now.

It is free and easy and I highly recommend giving it a try :)
