Grantsville is a web service that drafts grant applications for US nonprofits under $500K when the director writes the grants. It starts with an organization's documents, including its public Form 990, and connects facts in drafts to their source documents. It prepares letters of inquiry, full proposals, and funder portal answers tailored to field limits. Users can choose writing samples to shape the draft's voice, while the service flags numbers and claims for review. Grantsville cautions that generated text may be inaccurate or sound unlike the intended voice. First-time grant writers can use it, and no prior award is required. The service says it searches only that organization's documents when drafting and does not use them to write for another organization. Optional product analytics exclude identifying details and document content, among other listed data. The site describes the service as self-serve and suggests a consultant may be better for complex strategy or funder relationships. One application is free 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.
