Research the US-based nonprofits before donating. You can search for nonprofits or causes and dive deep into IRS and website disclosures. This is less like a charity rating site like CharityNavigator and ProPublica and more about helping donors decide whether to support a nonprofit or not.

Since the last update, I've taken in a lot of feedback and included foundations, trusts, and small entities totally over 8.8M filings and 2.2M entities.

Beyond any general feedback, what I'd love to know: what questions do you ask before donating?
