TL:DR - You could do more than you think is possible, in a fractin of the time.
I use Cursor almost exclusively, have since February of this year. Installed Hermes Agent two weeks ago. My use case may not be best example, as it's pretty niche.
My project is building digital TCG game from scratch - from an old physical game design, that I made with group of friends for GenCon 2015.
After cutting my workload by 1/3 having a dedicated partner (Hermes) that I can offload a bunch of stuff to - I decided yetserday to migrate to a hosted version so it's available 24/7.
It ran research for 2 hours last night unattended. It has it's own email, and I can chat/work from Telegram anywhere at anytime. It is useable across all my devices - macbook air as my on the go, gaming rig for home.
I use Deepseek V4 Pro as my daily driver for Hermes. I have spent 600 million context on that platform, just now hit $9/20 initial spend. I have used it consolidate all my documentation, do research, troubleshoot things Composer 2.5 couldn't sort on it's own. Help me migrate my DB, and about a thousand other use cases. I feel like I've been using this thing for months, it's been two weeks.
I already have a memory system where it's logging information on a daily basis, picking up skills from the work we're doing and it is genuinely the best tool I have used in my life. I will not be able to go back - I have cancelled Grok, Claude and am considering downgrading my Cursor $200/month sub to lesser tier, because of how useful it is.
Can it replace those subs, probably. But that's not what it's for. It can be an extension of you, your taste and your habits if you work with it long enough.
