Grantsville drafts grant applications for US nonprofits with budgets under $500K when the director handles grant writing. It works from an organization’s documents, beginning with its public Form 990, and ties draft facts to source documents for review. It can prepare letters of inquiry, full proposals, and answers for funder portals, with portal responses shaped to field limits. The tool flags numbers and claims that need checking before submission and can draw on writing selected by the user to shape its voice. Grantsville warns that generated text can be incorrect or sound unlike the intended voice. First-time grant writers can use it, and a previous award is not required. Its free plan covers one application with no credit card required; a letter of inquiry costs 99.00 USD per application, and a full application costs 299.00 USD per application. Grantsville is self-serve; a consultant may be a better fit for complex strategy or funder relationships. Use of the tool does not guarantee funding.
