Built on the PARA method
Your whole life,
organized on solid ground.
Cornerstone is the hub for your family's Projects, Areas, Resources, and Archives — one portal, one calendar, one history across your faith, family, finances, home, vehicles, and the apps that manage them.
Areas are the load-bearing walls. A setup wizard proposes yours — then every project, resource, and event finds its place.
Four categories. Everything filed.
P · A · R · A
The PARA method, from Tiago Forte's book of the same name, sorts everything in your life into four categories by actionability. Cornerstone makes them first-class objects instead of folders.
Projects
Short-term efforts with a finish line — replace the fence, file the taxes, plan the mission trip. Every project belongs to an Area, so nothing floats free.
Areas
Ongoing responsibilities with a standard to keep — Faith, Family, Home, Automotive. Never "done," always stewarded. Areas are the spine of Cornerstone.
Resources
Reference worth keeping — the smoker recipes, the HVAC manual, the insurance PDFs. Attached to the Areas that use them, searchable by everyone you share with.
Archives
Nothing is deleted; it's archived. The sold truck's full service ledger, last year's budget, the finished projects — kept, searchable, restorable.
One calendar, every area
Maintenance, money, and milestones on one timeline
Oil changes projected from mileage. Filter changes on schedule. Bills, appointments, and events from connected apps — forward as a calendar, backward as a permanent household history you can export.
A hub, not a monolith
Your Life Apps, connected
Cornerstone doesn't replace the apps that already work — it gives them shared sign-in, a shared map of your Areas, and a shared timeline. Apps connect with OAuth and signed webhooks; advanced users can register their own.
