You didn't start a nonprofit to write grants at midnight.
Catharsis is an AI grant writer that learns your mission and drafts winning proposals from a vetted evidence base — so your team can pour its hours back into the work only you can do.
Free to start · No credit card · Built by people who worked at nonprofits for a decade
“I've been the person working past midnight on a grant, when I could have been out in the community, actually making the impact. That's the trade every small nonprofit makes. It shouldn't have to.”
The math on grant writing is brutal.
This is the burden Catharsis lifts — so a two-person team stops losing entire weeks to a single application.
A single grant can swallow five full work weeks.
Most of that time ends in a polite no.
Money small orgs would rather spend on programs.
For most orgs, the grant writer is also everything else.

How many hours is your org losing to grant writing this year?
Plug in your numbers and see exactly what Catharsis gives back — in hours, dollars, and grants you could actually pursue.
A closed loop, from your mission to a finished draft.
It learns you
Onboarding discovers your mission, community, and past wins. An LGBTQ+ org and a watershed coalition get different, curated expertise.
It matches
Catharsis aligns each opportunity to a funder's priorities before it writes a single sentence — the way the best grant pros do.
It drafts from evidence
Every claim is written only from a vetted evidence base of what funded proposals share — never invented. Each line is cited.
You add the human
You proofread, edit in a click, and drop your voice where it matters most. The story stays yours.
Stop hunting for grants. Start winning the right ones.
Catharsis reads your mission, your location, and your budget, then scans thousands of open opportunities to surface only the ones worth your time — each with the amount, the deadline, and a tailored strategy for why you'll win it.
Not a chatbot. A closed system that only writes what it can prove.
Generic AI hallucinates numbers and invents impact. Catharsis can't. It writes strictly from an approved pool — your documented outcomes plus a curated base of what makes grants win — and cites every claim back to a source you can check.
Before you dive in.
Does Catharsis submit grant applications for us?+
No. Catharsis drafts; a human at your organization always reviews, edits, and submits. We never send anything to a funder on your behalf.
How do you keep the AI from inventing facts or numbers?+
Every draft is written only from your uploaded documents plus a curated evidence base — never from the model's general knowledge. Every claim is cited back to a source you can open and check yourself.
Do you train AI models on our documents?+
No. Your organization's documents and drafts are never used to train Anthropic's, or anyone else's, underlying AI models. See our privacy policy for the full picture.
Do we need to already be a registered 501(c)(3)?+
No. Catharsis is priced for nonprofits from the start — verifying your EIN is optional and never blocks you from signing up or drafting.
What does it cost?+
Seedling is free, forever, with one full grant draft a month and no card required. Paid plans unlock more drafts and features — see the full pricing page.
What happens to our documents if we cancel?+
You can export or delete anything at any time from account settings. If you close your account, we delete your organization's documents and drafts within 30 days.
Let AI carry the paperwork. Keep the part only humans can do.
back per grant cycle — that's real time in the community, not at the keyboard.
Catharsis drafts the structure; you bring the story, the relationships, the heart.
