The English phrase 'at will' does not have a single direct equivalent in Japanese. Translating it word-for-word (e.g., 意志で) will sound unnatural. Instead, choose an expression based on the intended nuance: freedom of action (自由に), personal preference (好きなように), or unrestricted access (いつでも).
自由に is neutral or positive, implying freedom. 勝手に often implies acting without regard for others, which can be negative. Use 勝手に carefully, especially in requests or instructions.
