Basically, we are repeating the same task. I would like to know if there are templates for checklist. This way, I don't have to retype it each time I assign it to someone.
There is currently a feature request card called Templates for boards, lists, cards, and checklists on the Trello Development board.
The note on it says:
We're still looking at how we want to implement this, but until we do, Phillip Epstein has created a Chrome Extension that does many of the things that people want.
So the answer is no, checklist templates do not currently exist.
