Methodology

We send a fixed set of buyer-intent prompts (e.g. “best note-taking & knowledge apps”, “top note-taking & knowledge apps for small teams”) to leading AI assistants and read their actual answers. A brand's score blends how often it's mentioned with how prominently (earlier mention = higher). Share of voice is its slice of all brand mentions in the category. Updated periodically — AI answers shift over time.
