A personal assistant for email, calendar, meeting notes, dictation and errands that runs its own models locally on your Mac, so content stays on your computer.

Underdog: In beta, invite only. Get it at underdog.ai.

Underdog is a personal AI assistant for email, calendar, meeting notes, dictation and errands that runs entirely on the user's computer. It uses its own local models, including Woof 4B, Saluki 27B and Underdog 27B, so summaries, drafts and answers are generated on-device rather than by a cloud AI service. Mail syncs directly with the user's email provider, saved memories can be viewed, edited or deleted, and each account gets its own vault with a locally held key. It strips remote images, scripts and tracking pixels, and a Naval mode switch stops it from calling home. Underdog is an invite-only beta for Apple silicon Macs, with Windows in beta and iPhone and iPad coming soon.
