Any thoughts on how to automate Upwork?

I was exploring different tools that can help agencies save time on Upwork and stumbled upon Convertix. The concept looks interesting, especially for teams that handle a lot of outreach and proposal submissions.
Has anyone here heard of it or had any experience with it? Just curious how it compares to other solutions and whether it's been useful in practice.

Here is the only option I tried: https://convertix.io/

Would appreciate any opinions or feedback. Thanks!
