Comparisons · GrantOrb vs Grantable
A writing assistant meters your usage. A grant writer delivers grants.
Grantable is probably the closest thing GrantOrb has to a true peer: AI writing built for nonprofits, an org profile that learns, real team features. If we're the two finalists on your shortlist, good — you're shopping well. The comparison comes down to what you're actually buying: Grantable sells you AI usage by the month. GrantOrb sells you finished, verified grant applications.

Three structural differences
1. Verified opportunities, not 990 archaeology. Grantable's discovery screens IRS 990 filings — who funded whom, historically. Useful context, but a funder's past giving doesn't mean a grant is open today. GrantOrb searches live, then verifies each opportunity against the funder's page before it reaches your list. See it working in our public verified-grants directory.
2. Grants, not tokens. Grantable's tiers cap AI usage at multipliers (15x on Starter, 45x on Pro). Heavy month? You feel the ceiling. GrantOrb counts the only unit you care about — complete grant applications — with unlimited revisions on each until it's right.
3. A human's there if you ever want one. The AI does an excellent job on its own — but every GrantOrb plan also includes a grant expert you can check in with, for the peace of mind of a second set of eyes when you want it. It's not a step you have to take; it's just there. None of the other AI tools include it.
Who each one is really designed for
This is the deepest difference, and it shapes everything else. Grantable is built as a professional's workspace — organizational memory that reuses your past proposals, an inline editor you drive, an Agency Hub for managing clients. That design assumes the person at the keyboard is a grant writer or consultant producing many applications from a library they've built. GrantOrb starts from the opposite user: the nonprofit itself — a program lead, an executive director, a volunteer — who has never written a grant and shouldn't have to become a grant writer to get funded. So the whole product is a guided path (talk to it, get matched, get a finished draft) rather than a workspace to operate. If you're a consultant with a proposal library, Grantable's workflow will feel natural. If you're the organization that needs the grant, GrantOrb was designed for you.
What the drafts read like
Grantable's writing engine starts, in its own words, "from everything it knows about your organization" — your past proposals and answers. That's a real strength for veterans with a deep library, and its ceiling: the drafts are as good as what you've already written. GrantOrb writes each proposal fresh against the specific funder — researching your impact data, building the narrative section by section so the story holds together end to end, and deliberately writing in plain language instead of grant-speak (funders are humans; "we leverage cross-sectoral synergies" has never moved one). Then it scores the draft against the funder's criteria and revises, unlimited, until it's submission-ready. Both tools are free to try: same organization, same grant, two drafts. Read them side by side — that test is the whole argument.
How is GrantOrb different from Grantable?
Both use AI to write grant proposals, and Grantable is a credible product — but they're designed for different people. Grantable is a professional's workspace (library reuse, an editor you drive, an agency hub), built for grant writers and consultants; GrantOrb is built to empower the nonprofit itself to write its own grant with a guided path. The concrete differences: GrantOrb verifies every discovered opportunity against the funder's actual page (Grantable screens IRS 990 filings — useful history, but not confirmation a grant is open now); GrantOrb includes automated grant discovery on every plan while Grantable gates it behind the $150/month Pro tier; every GrantOrb plan also puts a human grant expert on hand if you ever want a second opinion; and GrantOrb prices per grant ($26–50 each) rather than metering AI usage per month.
Is Grantable cheaper?
Grantable's Starter is $50/month (about $600/year) but doesn't include automated funder discovery — that's Pro at $150/month, about $1,800/year. GrantOrb Starter is $499/year with discovery, verification, writing, revisions, and a human expert on hand — all in. Nonprofit discounts on Grantable (50% off for one year for small 501(c)(3)s) narrow the gap for year one; the structural difference — metered usage vs complete grants — remains. Prices verified July 2026.
What does Grantable do well?
Its organizational memory is genuinely nice — it learns from your past proposals and reuses your best answers, and its inline editor is polished. If you write many similar applications yourself and want a smart autocomplete for that workflow, Grantable fits. GrantOrb's bet is different: most nonprofits don't want a better editor, they want the proposal done and checked.
Judge by the finished proposal.
Both tools are free to try. Set up the same organization in each, run the same grant, and read the two drafts side by side. We built GrantOrb to win that test.
