Constant critic
A straightforward phrase for someone who repeatedly judges or criticizes other people or their work.
Example: He became known as a constant critic of every new initiative.
Chronic complainer
Fits someone who repeatedly expresses dissatisfaction, even when the issue is not specifically a fault.
Example: The chronic complainer found something wrong with every hotel we suggested.
Carper
A formal or literary word for someone who continually finds fault or complains.
Example: The article dismissed the loudest carpers but addressed the substantive criticism.
Quibbler
Someone who objects over minor points or makes small, often pedantic distinctions.
Example: A quibbler can turn a simple discussion into an argument over wording.
Hypercritical person
Describes someone who judges others or things too harshly and focuses excessively on faults.
