ProposalMint
ProposalMint is a web-based grant analysis and proposal workspace for nonprofit organizations. It builds nonprofit profiles from public records, websites, and information users submit, then surfaces details that need confirmation. Grant opportunities receive fit and readiness scores, with an explanation of whether each is a strong, moderate, or weak match. AI agents draft proposals in sections with citations and claim-level support, while flagging unsupported claims and compliance risks. Users can review, edit, confirm, or dismiss draft items; a compliance check blocks export until issues are cleared. Federal workflows include checking SAM.gov readiness and organizing entity details for Grants.gov submission preparation. The platform uses public nonprofit records and data from IRS records, SAM.gov, Grants.gov, and state registries. Its privacy policy says organizational data is not used to train AI models for other users or third parties, and is not shared with advertisers or marketing partners. The Free plan includes profile building, opportunity search, match scoring, readiness assessment, a foundation explorer, and document management. Pro is $29 a month.
