What it is

Grantsville is a paid web service for US nonprofits under $500K whose directors write grant applications. It reads an organization’s documents, beginning with its public Form 990, and links statements in drafts to source documents. The service prepares letters of inquiry, full proposals, and answers for funder portals, shaping portal responses to field limits. It flags numbers and claims for review before submission. Users can provide selected writing so drafts follow that voice, although Grantsville says generated text may be wrong or sound off. First-time grant writers can use it without a prior award. Grantsville describes itself as self-serve; a consultant may better fit complex strategy or funder relationships. It says drafting searches only the organization’s documents and does not use them for another organization. One first application is free with no credit card. A letter of inquiry costs $99, and a full application costs $299.
