Sigil Wen(@0xSigil):I designed Underdog as an OS because your life shouldn’t split into fragmented apps. Your email, calendar, browser, voice, files, and meetings all give the AI you own context. It works better when it can see the full picture. Fly through your entire “context/life” with keyboard shortcuts, or hands free while underdog is standby. Seamless. Intuitive. At your fingertips.
