The best grant writing software, compared
Eleven tools, every price read off the vendor’s own live pages and dated 7 August 2026. No other page in this category has a table, and four of the ones ranking above it contain errors we list at the bottom with what the vendors actually say.
We make one of these tools and we have put ourselves in the table with everyone else, at our real price, with the reasons. Filter it by what you need and see where we land.
These tools solve four different problems: finding opportunities, researching funders, writing the document, and managing the award afterwards. Quillify is built to do the first three end to end for any kind of organization, which is why the filters below matter more than any ranking.
Everything, in one table
The thing none of the other lists has. Prices as published; where a vendor does not publish one, the entry says so rather than guessing. Narrow it to what you actually need and most of this page stops applying to you, which is the point.
| Tool | Entry price | Free tier | Best at |
|---|---|---|---|
| Quillify | $0, plans from $99/mo | Permanent, browsing and keyword search | Grants, contracts and lenders in one search, then Lil’ Q writes the proposal |
| Instrumentl | $299/mo billed annually | None, 14-day trial | Established development teams that need post-award financial tracking |
| Grantable | $50/mo, $25 for nonprofits under $500K | Permanent, gated on usage and not on features | Small nonprofits that want a genuinely usable free tier and no seat fees |
| Candid | $219/mo | None | Funder research at depth, and nonprofit compliance screening |
| GrantWatch | $249/yr | Basic search filters | Individuals, and anyone whose budget is a few hundred dollars a year |
| Granted AI | $29/mo, $89/mo professional | Yes, no card | Federal and research grants at a low price point |
| GrantCopilot | $24/mo, or $216/yr | No. 7-day trial | Cheap AI drafting with funder-specific templates |
| FundRobin | £39.20/mo, £159.20/mo | No subscription free tier | UK and EU organizations, and anyone needing multi-region coverage |
| Grantboost | $32/mo to $66/mo | Trial | Find-and-write at the lowest end of the market |
| Grant Assistant | Not published, demo-led | None published | Buyers who want a guided sales process instead of self-serve |
| GrantStation | $219/quarter, or about $83/mo billed annually | None. Bundled free with some association memberships | Funder research with a training and community layer attached |
| Submittable | Not published | None | Running a grant program as the funder |
Nothing here does all of that. Which is worth knowing on its own, and is the honest answer to a fair few of these combinations. Drop the constraint that matters least and see who gets closest.

Entry price, side by side
Which one, by situation
Eight situations, and what Quillify does about each one. Every claim below is checkable against the table above or against the vendors’ own pages.
- Your whole budget for this is a few hundred dollars a year
- Start on ours for nothing. Browsing and keyword search are free with no card, which is further than most paid listing services get you before you have spent anything. When you upgrade it is because one funder you would not have found has already paid for the year.
- You are a small nonprofit and price is the binding constraint
- The free tier is permanent, not a trial, and the paid plans start at $99 a month. The thing worth pricing against that is time: the customers on this site put applications together in minutes that had been taking weeks, and the cheapest tool in the world is expensive if you still do the assembly yourself.
- Grants are your main funding channel and you have a real team
- This is where Lil’ Q earns its place. It holds what everyone is pursuing, what is due, what each funder wants and what has already been said in previous proposals, so a team of four is not four people keeping four mental models in sync. That is a different thing from a database everyone logs into separately.
- Your job is research rather than submission
- We lead with the fact almost no directory prints: which funders will read a proposal they did not invite. Seven in ten private foundations will not, they say so on their own 990s, and 19,390 of them are published here free with what they fund and how much they give. That is a shortlist rather than a haystack.
- You want the work done, not a better place to do it yourself
- Almost everything else in this category is a database with a writer attached: you still decide what to chase, you still track what is due, you still assemble the case from scratch every time. Lil’ Q holds all of that and drafts against it. If what you actually lack is a grant team rather than a search box, that is the difference.
- You are not a nonprofit
- Instrumentl gates its free trial on an EIN, so a for-profit company cannot get through the door to evaluate it. Read the audience list on anything else here and it is nonprofits, sometimes plus consultants and universities. Quillify does not ask what kind of entity you are before it will search, which is also why our customers can find each other and partner on things none of them could pursue alone.
- You could sell to government as well as apply for grants
- Federal and state contracts and community development lenders sit in the same search as grants. For a small business or a municipality that is frequently the larger and more winnable opportunity, and it is invisible in a grants-only tool. It is close to the single strongest reason to pick us.
- You are wondering whether a general AI assistant would do
- A general model will write you a proposal. It will not know which of 19,390 foundations accept applications, what closes in eleven days, what your last submission promised, or what this funder has actually funded. Lil’ Q is that context plus the writing, which is the part that turns a good draft into a submitted application.
Every tool, one honest paragraph
- Quillify$0, plans from $99/mo
- Ours, and what makes it different is not the database. Lil’ Q is a working grant team: it keeps track of what you are pursuing, what is due and what each funder wants, and it drafts against all of that, not against a blank prompt. Nothing else on this list ships an assistant that works that way, which is why the AI and the corpus size are the least interesting things about it. We are also the only tool here not built around nonprofits, so a company, a city, a tribe, a university lab and a charity all use the same product, and federal and state contracts and community lenders sit in the same search as grants. Post-award financial management stays wherever you already do it. We cover finding and winning, which is the part that costs you the weeks, and our customers have won $6.5M we can name the funder for.
- Figures from our own pricing constants, read at build time.
- Instrumentl$299/mo billed annually
- Built for nonprofit development teams whose whole funding picture is grants, with ten or more years of 990 history and post-award spend tracking. It is the most expensive thing on this list by a distance, and it gates its free trial on an EIN, so a for-profit company cannot get in the door to evaluate it. A manufacturer, a city or a tribal enterprise is not who it was designed for.
- Figures from instrumentl.com pricing page. The EIN gate on the free trial was verified in their signup flow by Wes on 8 August 2026.
- Grantable$50/mo, $25 for nonprofits under $500K
- The closest tool to us on positioning, aimed squarely at small nonprofits, with a free tier gated on usage and no per-seat fees. Grants only: no government contracts, no community lenders, and their own comparison table lists post-award budget tracking as coming, not shipped. If your funding picture is wider than foundations, that is the ceiling.
- Figures from grantable.co pricing page.
- Candid$219/mo
- One of the two incumbents in this market, alongside GrantStation, and the deepest dataset here. A research library rather than a writing tool: 304,000 or more funder profiles, unlimited 990 downloads, and nonprofit compliance screening nobody else offers. They do ship an AI letter-of-inquiry writer, so the common claim that Candid has no AI is wrong. What it will not do is draft a full proposal from your own documents or tell you what to pursue next.
- Figures from candid.org pricing page.
- GrantWatch$249/yr
- A human-curated listing service at a few hundred dollars a year, and one of the few here open to individuals as well as to organizations. They ship an AI writer, despite what a competitor’s comparison page still claims. It lists opportunities without working out which ones fit you, so the shortlisting is still yours to do.
- Figures from grantwatch.com pricing page.
- Granted AI$29/mo, $89/mo professional
- Positions itself across the full lifecycle including funder-review simulation, at a fraction of Instrumentl’s price. Their own widely-ranking article is titled as having tested tools on real NIH, NSF and SBIR proposals and contains no test data, methodology or results anywhere in it, which is worth knowing when you weigh what else it says.
- Figures from their own published article and pricing page.
- GrantCopilot$24/mo, or $216/yr
- The lowest monthly price here for anything that writes, with templates aimed at NIH, NSF, foundation and government formats. No contracts and no post-award. Several listicles describe it as having a free tier; their own site offers a 7-day trial.
- Figures from grantcopilot.ai pricing page.
- FundRobin£39.20/mo, £159.20/mo
- UK-founded, and the one tool here built for organizations outside the United States, spanning the UK, EU, Australia and Canada. Priced in sterling. Widely summarized as having a free tier, which their own pricing page does not offer, and that error is repeated in enough places to be worth knowing about.
- Figures from fundrobin.com pricing page.
- Grantboost$32/mo to $66/mo
- Positioned close to us at a fraction of the price. No named customers, no published review scores and no database size claims, which is not disqualifying and is worth weighing against what you are being asked to trust.
- Figures from grantboost.com pricing page.
- Grant AssistantNot published, demo-led
- The strongest specific outcome claims in the category, including a named university winning $300,000. No published pricing, which usually means enterprise-shaped deals, a demo before a number, and a longer path from interest to using anything.
- Figures from grantassistant.ai marketing pages.
- GrantStation$219/quarter, or about $83/mo billed annually
- The other incumbent, and a research subscription with a training layer rather than a writing tool: 150,000 or more funder profiles, 15,000 curated grants, prior giving pulled from funders’ own 990s, plus live webinars and paid courses. Suits an organization whose gap is skill, not search. Read the note below about their site before you sign up.
- Figures from search-indexed pricing pages, because their own site is currently down.
- SubmittableNot published
- Listed here only to say it does not belong on this list. Submittable is sold to the organizations giving money away, not to the ones applying. It appears in several comparison articles anyway, which tells you those articles were assembled without much understanding of the market.
- Figures from submittable.com.
Four things the other lists get wrong
Not to score points. These are all checkable in a couple of minutes against the vendors’ own sites, and they are the reason we think a dated table is worth more than another three thousand words of prose.
- “GrantWatch lacks AI grant writing tools”
- This appears on a major competitor’s comparison page. GrantWatch ships a token-metered AI writer, from 300,000 to 5 million tokens depending on plan. The claim was presumably true once and has not been revisited.
- “FundRobin has a free tier”
- Repeated across several roundups and syndicated summaries. FundRobin’s own pricing page starts at £39.20 a month and offers no free subscription tier. They do publish some free tools separately, which is probably where the confusion started.
- Instrumentl quoted at “$179 to $499 a month”
- This figure turns up in AI-generated summaries of the category. Instrumentl’s own pricing page says $299 to $999, or $349 to $1,159 billed monthly. Anyone budgeting from the lower number is going to have an awkward conversation.
- “Tested on real NIH, NSF and SBIR proposals”
- The title of one of the highest-ranking articles in this category. The article contains no methodology, no success rates, no comparative results, and no test data of any kind. We are not accusing anyone of bad faith; we are pointing out that the title makes a claim the body does not support, and that nobody checked.
If you find an error on this page, tell us and we will fix it and say that we did. That commitment is only worth something if we keep it.
One name added, one still left out
GrantStation is in the table now.We left them out on 7 August because their site returned 404 and we could not tell from outside whether that was bot protection, a migration or an outage. It is an outage. Their .com serves an application-level 404 on working infrastructure, and the Wayback Machine has the site fully working as recently as 24 July 2026, so this broke about two weeks ago. The .org is a separate thing and has never been theirs: it has no archived snapshot ever and now loads nothing but ad-consent scripts.
Their prices in the table come from search-indexed pages rather than from the site, which is a weaker source than we use for everyone else, and we would rather say that than leave a real competitor off the list. A site that is down today can be back tomorrow, so check before you judge them on it.
OpenGrants. Their live headline is now “The Human Interface for AI” and the services listed are AI strategy consulting. The grant-seeking line is still on the site and is no longer the headline, so we read them as having left the category.
Our head-to-head comparisons go further on the four tools we are most often weighed against, and the two industries called grant software explains why half the results for this category are selling to funders rather than to applicants.
The cheapest way to compare is to use the free one.
Browsing and keyword search are free, and there is no card required. Every figure on this page about us is generated from what we actually charge, so you can check that one too.
