Description

Underdog is a private, local AI assistant for Mac that handles email, calendar, and task management entirely on-device, aimed at users who want AI help with day-to-day organization without their email and calendar data leaving their machine to a cloud service. It is aimed at privacy-conscious Mac users who want AI productivity help without a cloud-based assistant reading their inbox and calendar.

Logseq is a free, open-source (AGPL) note-taking and personal knowledge management app built around an outliner and a bidirectional-linked knowledge graph, storing everything as local Markdown/plain-text files. It's aimed at researchers, students, developers, and privacy-conscious individuals who want full control and ownership of their data rather than a cloud-locked notebook. What most sets it apart is its local-first, plain-text foundation combined with a powerful query language and an extensible plugin ecosystem.
