The Whitcomb Trust
A trust contest with five parties, 27 events spanning 80+ years. Lanes for the decedent, trustee, contestant, neighbor, and caregiver. The classic T&E use case.
A visual timeline editor
Make sense of years on a single canvas.
PrizmLine turns scattered dates and documents into a clean, citable timeline. Built for trust and estate work, generalized for any story that spans years — personal histories, organizational milestones, research timelines.
Visual canvas
Swim lanes per person, events plotted by date. Pan, zoom, and reframe the years that matter.
Collaborate
Invite teammates by email or share link. Roles, presence, notifications when someone tags you.
Source everything
Attach files, PDFs, photos, and excerpts to any event. Citations stay with the timeline when you export.
