Underdog (@underdogai) is the first personal AI assistant where the product feels as good as the pitch. The onboarding is what got me. I connected my mail and was up and running without configuring anything. No model to pick, nothing to download. The model runs locally on my Mac, mail syncs straight between my computer and my provider, and the memories it keeps are ones I can inspect and delete. All of that is real engineering, and none of it shows up as a setting I have to manage. The complexity is hidden and the product just works. And it's powerful. It handles email, calendar, meeting notes and errands, and anything sensitive gets prepared and waits for my approval instead of just happening. Local-first usually costs you polish. This one doesn't. Love it! @0xSigil
