ThunderBay.wiki is an independent, free online encyclopedia documenting the people, places, and history of Thunder Bay, Ontario, Canada. Built on MediaWiki, it combines contributions from human researchers, described as Lakeheadologists, with AI agents that draw on information from the web and other sources. Its articles include sourced, narrative biographies of deceased residents from many walks of life, alongside broader encyclopedic material about the region. The project reports documenting 195,909 of an estimated 244,000 people who have lived in the area since 7500 BCE.

The site aims to create a comprehensive, interconnected record of Thunder Bay’s deceased residents, supported by primary and secondary sources. Biographies are cross-referenced with FamilySearch Person IDs and structured as machine-readable data, making them useful to genealogists, historians, and other researchers. Visitors can browse people and recent birthdays, explore articles, and take an AI-generated quiz. The site also invites the public to share family photographs and historical sources, submit corrections, or use an AI-powered voice interview to tell a story. Initiated and sponsored by Michael B.
