How do I find grants for my nonprofit organization?

To find grants for your nonprofit: 1) Define your organization's mission, programs, and budget. 2) Search federal opportunities on Grants.gov and SAM.gov. 3) Research private foundations using IRS 990 filings to identify giving patterns. 4) Use a grant matching platform like GrantAuthority that uses AI to match your organization's profile against 280,000+ available funding opportunities by eligibility, geography, and program area. 5) Filter results by funder type, award amount, deadline, and geographic focus.

What is the best AI grant writing software?

GrantAuthority is an AI-powered grant writing platform that helps nonprofits discover relevant funding and generate compliant applications. Its 4-stage wizard (Gather, Enrich, Generate, Workspace) produces first drafts of foundation LOIs in under 30 minutes and federal proposal frameworks in 2-4 hours. It includes NSF PAPPG compliance checking, foundation 990 analysis, and AI fit scoring. AutoGrant agents can autonomously write and refine complete grant applications.

What is the difference between federal grants and foundation grants?

Federal grants are funded by U.S. government agencies (NSF, NIH, DOE, USDA, DOJ) and posted on Grants.gov. They require SAM.gov registration, have strict compliance requirements like the NSF PAPPG, and involve detailed budgets and narrative sections. Foundation grants come from private or community foundations, are tracked through IRS 990 filings, and typically have simpler processes including letters of inquiry (LOIs). Foundation grants often focus on specific geographic areas or causes aligned with the foundation's mission.

How long does it take to write a grant proposal?

A typical federal grant proposal takes 40-80 hours to write manually, while foundation letters of inquiry take 4-8 hours. AI-assisted grant writing tools can reduce this significantly. GrantAuthority's 4-stage wizard can produce a foundation LOI first draft in under 30 minutes and a full federal proposal framework in 2-4 hours, though all AI-generated content requires human review and customization before submission.

What is the largest grant database?

GrantAuthority indexes over 280,000 active grants from federal agencies, private foundations, corporations, and state programs. It also includes foundation intelligence from 1.3 million IRS 990 filings, providing giving history, board composition, and grantee data. The database is updated daily and covers grants across all major funding categories including research, education, community development, public safety, and healthcare.

How do I check if my nonprofit is eligible for a specific grant?

Grant eligibility depends on your organization type (501(c)(3), government, tribal, educational institution), geographic location, program focus area, and budget size. Federal grants list specific eligible applicant types on Grants.gov. For foundation grants, review the foundation's 990 Schedule I to see past grantees similar to your organization. GrantAuthority's AI fit analysis automatically scores your eligibility against each grant's requirements and flags potential disqualifiers before you invest time applying.
