can i ran a local llm as an assitant in a thinkpad T480?

Pretty straight forward, im new to this. Im wondering what specs would I need to achieve this, I know that an i7 is necessary, but how much RAM would I need? This is my daily driver so thats also important. My main objective with this would be a personal encyclopedia as well as a personal assitant making basic tasks like some organization and give me calendar appointments. Ideally I would like to use it through my too. Is this realistic and how hard would it be to learn? Im not tech savy at all but Im willing to learn as this is a long term project Im focusing on so time is not an issue.
