Not fit for purpose
In my experience, Claude repeatedly failed to follow clear instructions and made mistake after mistake. Even simple tasks took several attempts to get right, and every correction seemed to create a new problem somewhere else.
The most frustrating part is that while it is wasting your time producing unusable work, it is also burning through your credits and constantly telling you that you have run out. You are effectively paying for its mistakes, then being asked to pay again so it can attempt to fix them.
I spent more time checking, correcting and rebuilding the work than I would have spent doing it myself. The service felt unreliable, expensive and completely unfit for professional work where accuracy actually matters.
A horrendous experience. I would not recommend it.
