Cronometer may have options for both raw and cooked foods, so in that case it's up to you!
If you are using generic foods from NCCDB when logging foods in Cronometer, foods that are typically eaten both raw and cooked will specify in the name of the food. For example, measure "Broccoli, Raw" before cooking, while "Broccoli, Cooked" should be measured after it has been cooked. Similarly, "Quinoa, Dry" should be weighed before cooking, while "Quinoa, Cooked" should be weighed after cooking.
Some foods from the NCCDB do not specify in the name of the food, but they are meant to represent the most common method of preparation or the way that most people would consume the food. For things like ground meat, roasts, chicken breast, etc. you can reasonably assume that the nutrition values are for the cooked meat. Meats from the USDA database usually specify whether the meat is raw or cooked/roasted/pan fried/etc right in the name of the food.
For brand name products, this is up to the manufacturer whether they would like to report the nutrition values for the raw or cooked meat and so it varies. Check the label to see if they have specified in the serving size. Otherwise, try comparing to an NCCDB version to see if it matches more closely to the raw or cooked version of the food.
