About FactIQ and these updates

  • What FactIQ is. FactIQ is a database of official statistics from government agencies, central banks and international organisations in the US, China, India, Europe and elsewhere. AI assistants such as Claude and ChatGPT connect to it to look up the exact figures and cite the agency that published them. It also holds what companies report in their filings and say on their earnings calls.
  • How an update is made. When a source publishes new figures, FactIQ loads them and an AI model writes a short summary of what changed. Before it is published, code checks that every number in the summary matches FactIQ's record of the release, and a second review checks that nothing is overstated. Values that look like errors in the source data are left out.
  • Where the numbers come from. Each key figure links to the full series, with its source, units and history.
