Ariadne was a princess from Greek mythology; she provided Theseus with the thread that helped him escape the Labyrinth. This is a personal project management tool, built for people with too many things going on. It helps track projects, deadlines, upcoming work, the people involved, and generates the all important reports you need to justify what you did last week.
It also provides a local MCP server so you can get your upcoming task information into your other systems. AI Import extracts tasks from any random text - emails, project plans, slack notifications and saves it as tasks in the system. It also integrates with Todoist so you can push the day’s agenda to an app running in your pocket.
Your daily interactions start with the command center - what’s overdue, due today, due soon, what’s blocked. Underneath that are projects with dependency graphs and collaborators that let you keep track of what’s happening.
People are first-class objects here rather than a text field. Contacts carry reporting lines and contact information. There’s tag support as well- you tag work against a vocabulary you can rename and merge across the whole workspace. Reports come out as plain text you can paste into an email to make it easier to communicate out what you are doing.
Everything you enter lives on your own filesystem as human-readable JSON, with attachments as ordinary files in a folder. There is no account, no login, no server and no database, which has two consequences that matter more than any feature: the application keeps working when the network does not, and the data outlives the application. If Ariadne disappeared tomorrow the JSON would still open in a text editor and the attachments would still be files.
