Claude CoWork absolutely dominates - I use it continuously now when connecting to mail, calendar, jira, google docs - any type of knowledge work. Almost everyone I know (at work) who does "Knowledge work" type stuff (as opposed to coding) uses it as their primary pane-of-glass now.
I have 15+ years of top 1 percentile knowledge using awk to process complex unstructured documents - and I don't even bother anymore - just dump the dataset into CoWork and ask it to do the analysis, cross check its work.
I did it last night during a call for a reasonably complex 10,000 node cluster with all sorts of jobs/allocations/memory constraints. I didn't even attempt to throw together a quick awk script (which would have taken me 7-8 minutes - it was a beast) - just did a nomad-job-inspect of a couple hundred jobs, and dumped all the data at CoWork (real time, while talking on the zoom) and said, "Get me the Memory/CPU requirements based on job/datacenter/SKU constraints and give me a summary Table".
Any normal person would have take 3-4 hours, minimum - futzing with google sheets and such (lots of task/taskgroup independent counts). Even I would have taken a minimum of 10 minutes. Cowork had it for me in under 30 seconds - I didn't even have to really look away from the zoom.
I haven't use the Atlassian Jira interface to manage my sprints/issues in 6+ weeks. All that cognitive drain is gone - I just ask CoWork to update the sprints, link issues to change-notices, comment and change status, set epics, etc... Zero need to find the damn field in Jira.
CoWork is legit.
