The Common App gives you 150 characters to describe each activity. That is about one sentence. Activity Studio helps you make every character count.
What makes a strong description
Effective descriptions lead with impact or action rather than your title, and use specific numbers like funds raised, team size, or events organized. They show progression or growth over time and avoid generic phrases like "helped the community" or "gained leadership skills."
Using the AI optimizer
Paste your draft description and Activity Studio will suggest tighter phrasing, flag vague language, and help you hit the character limit without losing meaning. You can compare before and after versions side by side.
