SageAgenda, an unfinished resurrection of Lotus Agenda
A web reimplementation and research archive for Lotus Agenda, the short-lived DOS information manager that organized notes after you wrote them.
Field notes
SageAgenda documents Lotus Agenda’s unusual approach to information management: categories carry conditions and actions, while views can update the underlying database rather than merely display it. The project is reconstructing that model from a 1990 design paper and preserves six original manuals, freeware binaries, and related tools. Its archive records whether sources were read, summarized, or only seen; the full index contains 63 sources. The site explicitly states that no runnable version has shipped and invites readers to join a waitlist.
