We believe public information should be genuinely accessible. Official registries, court records, and open-source data exist to inform the public — but most of it is scattered, inconsistent, and hard to use. Our mission is to bring that information together in one place so people can make better everyday decisions.
ClarityCheck offers six lookup services, each drawing on public records and OSINT sources. Reports are delivered in seconds and saved to your account so you can return to them later.
ClarityCheck does not own private databases or collect information from users' devices. We aggregate data from publicly available sources — government registries, court records, corporate filings, public social media, and licensed OSINT vendors — and organize it into readable reports.
Our databases are refreshed daily for near-current accuracy, but results are not real time. Some records may be incomplete or outdated depending on the source jurisdiction. We cover 98.4% of North American records and 95% of European records, with global coverage at varying completion rates.
ClarityCheck is designed for personal informational purposes. To be clear about what we are not:
