Hello Anthony,

If you want to replace those 2 tools which are completely different from the use case, I think I will suggest Asana if you want something cheap and Monday if you want something more visual but a little bit more expensive. I agree with Slack. Slack is to communicate and you can integrate tasks and reminders there from the Project Management Tool but it is not a place to work on the tasks. And Jira is really powerful and complex. I think you will like Asana if you want something easy and Monday if you want something more visual. I didn't use Quip for a long time but I don't think will be an option in this case if you want something simpler, easy and cheaper.

Another option for me is Noton which is easy and simple too because connects very well with documentation.

I hope you found useful this recommendation.

All the best,
