How Grantable writes
Three steps from blank page to RFP-ready draft.
Reads your org once
Drop in your last proposal, your website, or your strategic plan. Grantable extracts your mission, programs, theory of change, and writing style — and remembers them across every future draft.
Writes section-by-section in your voice
Paste an RFP. Grantable produces a structured first draft pulling from your content library — narrative, logic model, budget justification, evaluation plan. No copy-paste from ChatGPT, no re-explaining your org each time.
Cross-checks the RFP before you hit send
Page limits, required sections, attachments, eligibility criteria, formatting rules — Grantable compares your draft to the RFP and flags anything missing. No more last-minute panic at 11pm the night before.
Will the AI make stuff up?
The honest answer: no — because Grantable wasn't built like ChatGPT.
Won't make stuff up
Every claim cites your content library and the funder's IRS 990. No fabricated grant amounts, no invented programs, no wrong eligibility.
Grounded in your org
Grantable reads your mission, past proposals, and program data once. From then on, every draft pulls from your actual content — not the open web.
You stay in control
The AI suggests. You approve. Every paragraph is editable, every change tracked. We don't auto-submit or send anything on your behalf.
