The Note-Taking Problem
Most people's notes are disorganized graveyards of half-formed ideas. We write things down but never find them again. Tags help but require discipline. Search works if you remember keywords. AI note-taking tools solve this by automatically organizing, connecting, and surfacing relevant notes. In 2026, they're essential for knowledge workers.
