CharitySense

CharitySense is a research and due diligence platform covering every U.S. nonprofit: 2.2 million organizations and 8.8 million IRS filings. Search by name, EIN, cause, location, or a plain-English question. Each profile brings together filing history, finances, grants, compensation, governance, foreign activity, related organizations, website disclosures, and multi-year trends. CharitySense checks filings against themselves. Balance sheets, totals, and schedule details must reconcile. When they do not, the exact discrepancy is shown. Ratings and charts link back to the filing, line item, or source page, so users can inspect the evidence instead of trusting a black-box score. For grantmakers, CharitySense supports the whole first-pass workflow: discover organizations by mission and location, compare peers, inspect money flows and governance, build a shortlist, and request deeper research. Ask CharitySense answers questions about each organization with citations. CharitySense is built as a direct alternative to Cause IQ, Candid, and Charity Navigator. It covers every U.S. nonprofit, checks the underlying filings, exposes the evidence behind each answer, and makes the same data available through an API. The public API gives researchers, developers, and AI agents access to the same source-backed data. Core research is free and requires no account.
