Hull strawberries if necessary; puree in a food processor. Remove and set aside. In a small saucepan, sprinkle gelatin over cold water; let stand for 1 minute. Heat over low heat, stirring until gelatin is completely dissolved. Transfer to the food processor; add the cream cheese, cottage cheese and sugar substitute. Cover and process until smooth.
For garnish, wash strawberries and gently pat with paper towels until completely dry. Cut tops off berries. In a microwave, melt chocolate; stir until smooth. Dip each berry tip until half of the berry is coated, allowing excess to drip off. Place with tips pointing up on a waxed paper-lined baking sheet; refrigerate for at least 30 minutes.
