Editorial Verdict

AI-researched, not hands-on tested

Underdog runs an AI assistant for email, calendar, and tasks locally on your Mac, which makes it a fit for people who want automated inbox and schedule help but don't want that data sent to a cloud service to be processed. That on-device approach is the whole point, so it will appeal most to privacy-conscious Mac users and won't be an option for anyone on Windows, Linux, or the web. It's free, which lowers the risk of trying it. Beyond that, there's little public detail on how well it actually handles email triage, scheduling, or task management, so how capable the AI is in practice is hard to judge from the available information.
