In focus
The smaller stones of Stonehenge come from the Preseli Hills in west Wales, about 240 kilometres away. Were they carried by people or left nearby by glaciers?
Four steps from a question to a verdict that anyone can audit.
State a claim to verify, or ask an open question and list the competing explanations.
Add documents, recordings, data or testimony for or against. Facts need a source that others can check.
Disagree? Attach counter-evidence directly to the entry you dispute. Good rebuttals weaken it, support strengthens it.
Ratings weigh every entry. The meter moves live, and moderators close the case once the picture is clear.

From viral claims and predictions to cold cases and historical riddles.
Every factual entry links to something you can open and check. Each case keeps a full list of its sources.
People rate how strong an argument is and whether it is a fact, plausible or speculation.
Counter-arguments attach to the exact entry they answer, so a thread reads like a chain of reasoning.
The method is public and the same for everyone. You can trace a verdict back to every entry behind it.
The assistant summarises and suggests what to check. It has no vote, never decides, and does not add evidence to community cases.
Eight languages, cases from any country, and rules that protect private individuals.
A community platform for checking claims and solving open questions. People gather evidence with sources, rate it, challenge it and arrive at a verdict that anyone can audit.
Nobody decides alone. The meter is calculated from weighted community ratings and from how well each piece of evidence survives rebuttals. Moderators confirm the final verdict only when enough strong evidence points one way.
Viral claims, predictions and forecasts, historical mysteries, unexplained events, consumer and science questions, and more. Cases about private individuals and accusations without proof are not allowed.
Yes. Anyone can read, and a free account lets you add evidence, rate, comment and open cases. There is also an optional supporting membership for people who want to help pay for the service; it adds a seal and personal statistics and changes nothing in the verdicts.
An assistant writes short briefings, suggests what to check next and answers questions in discussions. Its content is always labelled AI and it has no vote. It does not add evidence to community cases; only the starter cases published at launch contain entries prepared with AI, and they are marked.
Anyone can report content. Moderators review reports, explain their decision and the author can appeal. Weak or false entries also lose weight when the community rates and rebuts them.
Open a case and let the community help you get to the bottom of it.
