Caelum turns claims into audit-grade provenance — source, timestamp, evidence, and how it changed over time — so institutions and communities can make defensible decisions.
Built for early partners, contributors, and supporters building the first pilots.

Most of what we see online is shaped by systems we don't control. Content travels fast. Accountability doesn't.
Caelum is building a shared trust layer under media, platforms, and applications. It helps you answer three simple questions:
Claims linked to sources, counterpoints, and history — see why something is being said.
Knowledge in structures people can explore and improve. Less scrolling, more understanding.
Systems that remember track records — rewarding clarity and honest revision over clicks.
A calm sky for sovereign intelligence. A new truth for a new world. A system designed to evolve.
Read the ManifestoThree pillars that make trust auditable, not assumed.
Every claim links to its source — who said it, when, and where. No assertion without a receipt.
Claims change. We track what changed, when, and why — so history can't be quietly rewritten.
Trust is earned over time. Track records, governance rules, and transparent incentives — not just upvotes.
We are surrounded by more information than ever — and yet it's getting harder to know what to believe.
AI can generate convincing content at scale
Institutions are losing public confidence
"Going viral" often pays better than being accurate
Bad decisions. Polarized communities. A quiet sense that the ground is shifting.
Where we're proving the model — one claim at a time.
Mapping claims, costs, and timelines around Hawaii's largest public project.
We're quietly looking for people who feel the cost of the current trust breakdown, and are willing to explore deeper, slower solutions.
Early-stage and selective. We read everything.
