ProposalMint

ProposalMint is a web-based grant workspace for nonprofits, best suited to small teams managing several deadlines and federal applications. Its strongest advantage is connecting grant-fit analysis to drafting and compliance review; the catch is that AI-assisted drafting is reserved for the paid plan and every output still needs human verification.

Overview

ProposalMint brings nonprofit profiling, grant discovery, proposal preparation and federal-readiness tasks into one workspace. That makes it a more compelling fit for organizations trying to manage a grant pipeline than for those that need only a searchable funder directory or a standalone writing tool. Its review gates add structure, but they do not transfer responsibility for accuracy away from the applicant.

Key features

Profiles draw on public records, websites and information supplied by users, and surface facts that need confirmation. Matching scores opportunities for fit and readiness, with strong, moderate or weak assessments and explanations. This can help a lean team decide where to spend limited proposal time, though the scores are a prioritization aid rather than a substitute for checking eligibility and fit.

On Pro, AI agents generate sectioned proposal drafts with citations and claim-level support. The Critic–Writer revision loop, compliance officer check, funder intelligence, voice library and PDF Form Chat extend that drafting workflow. Users can review, edit, confirm or dismiss draft items; export is blocked until compliance issues are cleared. That is a useful safeguard, not a guarantee that a proposal is correct: users remain responsible for verifying AI-generated material before submission.

Federal workflows assess SAM.gov readiness and organize entity details for Grants.gov 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. It also describes encryption in transit and at rest, organization-scoped role-based access controls, JWT-based authentication with JWKS verification, audit-trail request IDs, and regular security assessments and monitoring.

Pricing

The Free plan costs nothing and includes EIN-based profile building from 8+ sources, grant browsing and search, smart match scoring, SAM.gov readiness assessment, a foundation explorer, and document upload and management. It is a substantial starting point for organizations that want to profile themselves and explore opportunities, but it does not include AI proposal generation or the Pro review tools.

Pro costs $29 a month, billed $29/month. It adds AI multi-agent proposal generation, the Critic–Writer revision loop, compliance officer final check, PDF Form Chat, funder intelligence, a voice library and priority support. For a grant writer or development lead who expects to draft and refine proposals regularly, those are the plan’s key reasons to upgrade. A free trial is available. The Pro plan includes priority support; support contact is [email protected].

Platforms

ProposalMint runs on the web, making it a fit for teams working in a browser-based grant workflow.

Who it's for

Nonprofit grant writers, development directors and program leaders managing multiple deadlines without enterprise-scale staffing are the clearest audience. Teams that need help with matching and federal readiness can start on Free; those seeking AI-assisted drafting and built-in review controls need Pro. Organizations that require fully automated, submission-ready writing should look elsewhere: users must review and verify generated drafts.

Pros and cons

Pro: Match scoring explains relative fit and readiness, helping small teams prioritize opportunities rather than just browse them.

Pro: Citations, claim-level support and an export-blocking compliance check create meaningful review steps before a draft leaves the workspace.

Pro: SAM.gov readiness and Grants.gov preparation address federal workflows alongside ordinary grant discovery.

Con: AI proposal generation and its review tools require the $29 a month Pro plan, while Free is limited to discovery, profile and readiness functions.

Con: Generated material remains a draft that users must check and verify, so it does not remove the need for grant-writing judgment.

Alternatives

For a broader comparison, see Nonprofit Grant Writing Software. Choose Granted AI if an API-based option matters alongside web access; it has a free plan and free trial. Mavenly is another API-and-web option with a free trial and a 500-requests-per-month Sandbox, while its Starter plan costs $49 a month.

GrantAppli may suit a team that wants a free plan capped at 3 grant projects. Grantable offers a free plan with 5 chat messages a day and file imports up to 10 MB, which is a better fit for readers comparing chat-led grant work. Grantboost gives free users 10 Writer chats and 10 grant views per month; its Find Grants plan is $32 a year, displayed as $32/mo.

Grantora may appeal to teams prioritizing a defined free allocation: its Community plan allows up to 4 Grant Project Outputs per year, with 5 MB storage and one admin and one writer user. Grantivo offers 10 free credits alongside unlimited proposals and drafts, while its Starter plan costs $29 as a one-time purchase. For readers seeking a paid service without a free plan, Instrumentl has a free trial; its Discover plan costs $299 a year, billed $299/month paid upfront annually, and allows up to 3 users.

Verdict

ProposalMint is a sound choice for a small nonprofit team that wants grant matching, proposal drafting and federal-readiness checks in the same workflow. Its strongest reason to choose it is the path from opportunity assessment to cited, compliance-reviewed drafts; its strongest reason to look elsewhere is that those drafting tools cost extra and still require careful human verification.
