By the end of this guide you will have a complete grant proposal draft built from the funder's own guidelines, with each section checked against the scoring criteria and ready for a final review by a person who knows your organisation. AI helps in three places: finding likely funders, turning the call text into an outline, and drafting and tightening sections from facts you supply.
If you want to write a grant proposal with AI, the first decision is whether you need a tool for the whole bid or just a good writing editor. Bid platforms handle requirements and compliance, nonprofit tools add funding search, and general editors give you a flexible place to draft. This guide compares five options from our Writing category and its neighbours.
Key takeaways
- Start from the funder's guidelines: extract every requirement and scoring criterion, outline against them, then draft each section from your own facts.
- The main decision is a bid platform (AutogenAI), a nonprofit funding assistant (Vee), or a general AI editor (Moonbeam, Spell).
- Prices vary widely: Spell lists a free plan, Moonbeam lists only paid plans, and AutogenAI is quoted on request.
- AI must never invent outcomes, statistics or budget figures. Someone accountable for your organisation has to verify the final text before it is submitted.
What you need before you start
- The funder's call. The full guidelines, eligibility rules, scoring criteria, word limits and deadline.
- Your facts. Mission, track record, past results, team biographies, the need you are addressing and a draft budget.
- Supporting evidence. Data and sources you are allowed to cite, kept in one folder.
- An account or a demo. AutogenAI is quoted after a demo or sales contact, Edgrapi needs an API key, and the editors run through an account.
- Time. A first draft can come together in a day. Planning, review and the budget take longer, so start well before the deadline.
- Difficulty. Moderate. The writing is the easy part; the strategy and the numbers are the hard part.
- Rules about AI. Some funders set rules on AI-assisted applications. Read the call for any such statement.
Which kind of AI tool fits this job
Pick by the size of the job and the type of organisation.
A proposal platform for the whole bid. AutogenAI covers RFPs, tenders and grant calls. It extracts requirements from the solicitation, builds an outline through a set-up wizard, drafts with compliance mapping, and runs an automated compliance review before you submit. A Sources panel shows which material the AI read and cited, and drafts export to Word, PowerPoint and InDesign. It lists a Grant Writer edition. Pricing is not published.
A nonprofit assistant that also finds funding. Vee is built for nonprofits. Its Grant teammate searches a database of more than 500,000 grants, sends matches and drafts applications for you to review and submit. It also writes social media posts, which you can ignore if you only need grants.
A funding data feed for developers. Edgrapi is an API and hosted MCP server that serves Grants.gov grants as JSON, alongside other US government data. It is for people who build their own search or alerts, not for writing the proposal itself.
A general AI editor for drafting. Moonbeam turns rough notes into an outline and then paragraphs, with templates and a chat inside the editor. Spell drafts a document from a plain-language prompt, lets you rewrite a highlighted section, supports live team editing and exports to Word, PDF or Markdown. Both suit teams that want control of the writing and will supply the funder-specific structure themselves.
Step 1: Break the guidelines into requirements
You finish with a checklist of everything the funder asks for and how it will score you.
- Read the full call, eligibility rules and scoring criteria twice.
- List every required section, attachment, word limit and deadline.
- Copy the scoring criteria into a table so you can map each to a section.
- If you use AutogenAI, upload the call document and let it extract the requirements, then compare its list with yours.
Check it worked by confirming that nothing in the guidelines is missing from your checklist.
Step 2: Find the right funder and confirm the fit
A well-written proposal sent to the wrong funder still fails.
- Describe your project in two sentences: who it helps, what changes and where.
- Search for matching programmes. Vee offers AI grant matching for nonprofits, and Edgrapi exposes Grants.gov data for developers who want to build their own search.
- Check eligibility yourself on the funder's page. A match from a tool is a lead, not a decision.
- Choose one call and note its deadline, award size and any previous winners you can find.
Check it worked by being able to explain in one sentence why this call fits this project.
Step 3: Choose a tool to write the grant proposal with AI
Pick the tool that matches the size of the bid.
- For a competitive or regulated bid with many requirements, a platform such as AutogenAI fits. Pricing is by quote, so ask for a demo.
- For a small nonprofit that also needs funding leads, Vee combines search and drafting. Its listing quotes different allowances on different help pages, so confirm the plan before you sign up.
- For a team writing in a document, try Spell, whose free plan covers 10 documents and 10k AI credits a month, or Moonbeam, which lists a 30-day money-back guarantee on paid plans.
- Check where your data goes before you upload anything confidential.
Check it worked by noting the plan, cost and any usage limits for your chosen tool.
Step 4: Build an outline from the criteria
An outline that mirrors the scoring criteria keeps the proposal on target.
- Create a section for each requirement, in the order the funder asks for them.
- Under each heading, list the facts and evidence you will use.
- In Moonbeam, paste rough notes into the Wizard to get an outline, or in Spell write a prompt describing the document you need.
- Share the outline with your team and agree who owns which section.
Check it worked by mapping every scoring criterion to at least one heading.
Step 5: Draft each section from your own facts
Let the AI do the first pass, but keep control of the content.
- Draft one section at a time, giving the AI the relevant facts, the word limit and the funder's wording.
- Ask for plain, specific language, not general claims. Replace any statement that lacks evidence.
- Rewrite weak passages by highlighting them and asking for a new version, which Spell supports.
- Never let the tool generate figures, outcomes, partners or citations on its own. Add them yourself from verified sources.
- Keep the budget narrative consistent with your spreadsheet, written or checked by someone in finance.
Check it worked by confirming that every number in the draft can be traced to a source you hold.
Step 6: Check compliance and quality
Run both a mechanical check and a human read before you submit.
- Compare the draft against your Step 1 checklist: sections, word counts, attachments and formatting.
- If you use AutogenAI, run its automated compliance review, which checks requirements before a document goes out.
- Ask a colleague who has not worked on it to score it against the criteria.
- Fix gaps, shorten padding and read the whole proposal once more for tone and consistency.
Check it worked by having a reviewer say they could score every criterion from your text.
Step 7: Finalise, export and submit
The last step is about accuracy and a clean submission.
- Have the person who is legally responsible for your organisation review and approve the final text.
- Export in the format the funder wants. AutogenAI lists Word, PowerPoint and InDesign, and Spell exports to Word, PDF and Markdown.
- Submit well before the deadline and save a copy of exactly what you sent.
- Keep your notes, so you can reuse the strongest passages next time.
Check it worked by receiving the funder's confirmation of submission.

Common mistakes to avoid
- Writing before reading. Drafting first and checking the guidelines later leads to missed criteria. Fix it by building the requirements checklist in Step 1.
- Trusting invented evidence. AI can produce confident statistics and citations that do not exist. Fix it by supplying every number yourself and verifying each source.
- Sending a generic proposal. A draft that could apply to any funder scores poorly. Fix it by quoting the funder's priorities and linking each section to a scoring criterion.
- Relying on a match without checking eligibility. A tool may list a grant you cannot win. Fix it by reading the eligibility rules on the funder's own page.
- Ignoring funder rules on AI. Some calls state what is allowed. Fix it by reading the call and disclosing AI use where required.
How we put this together
This is an evidence-based guide built from each tool's listing in our directory, which is compiled from the vendor's own site and pricing page. It is not a review based on using the tools.

Frequently asked questions
Is there a free way to write a grant proposal with AI?
Partly. Spell has a free plan with 10 documents and 10k AI credits a month, which is enough to try drafting. Edgrapi has a free plan of 100 credits a month for grant data. AutogenAI, Vee and Moonbeam are paid or quoted, so check each vendor's site for the current offer.
Can AI write a grant proposal that wins funding?
It can speed up the draft, but winning depends on a strong project, a good fit with the funder and accurate evidence, all of which come from you. Treat AI output as a first draft and have someone responsible for your organisation verify it.
Can I use AI to find grants?
Yes. Vee searches a database of more than 500,000 grants for nonprofits and sends matches, and Edgrapi serves Grants.gov data as JSON for developers. Confirm eligibility and deadlines on the funder's own page before you invest time in an application.
How long does it take to write a grant proposal with AI?
A first draft can come together quickly, but the listings give no standard timings. Most of your time should go to the requirements, the evidence, the budget and review. Start well before the deadline.
