From the Big Bang to today — the milestones, each one sourced.

Built against unsourced history
The internet is filling up with confident, machine-generated claims. SourcedStory goes the other way: every event carries its evidence, and the quality of that evidence is visible.
Every claim carries its sources
Events cite their evidence, and each source is graded — primary archives, peer-reviewed journals, reputable institutions. Unsourced claims are flagged, not hidden.
Zoom from eons to an afternoon
One canvas spans 13.8 billion years. Pan across eras, dive into a decade, and land on a single day — the timeline re-draws itself around whatever you focus on.
Build and publish your own
Draft privately with autosave, cite as you go, and publish when it’s ready — readers only ever see the version you chose to make public.
