The most insightful comment came from a member who suggested that your tagline should match how users actually use your product. If people primarily use your app for capturing meetings and conversations, positioning it around "thoughts" might miss the mark.
You also need to consider your target audience. As one member noted, what appeals to our tech-savvy community might not resonate with mainstream users.
