Clean workspace for non-profit fundraising teams.

Monitors roughly 1.5 million funding sources including grants.gov, foundation databases, and state portals, and surfaces matching opportunities daily with weekly alerts.
Each discovered opportunity receives a match score against your mission, programs, and projects so you can prioritize where to invest drafting effort.
Upload past proposals, annual reports, or just your website URL; the AI learns your programs and tone so drafts read like your own team wrote them.
Every grant in your funnel is visible in one place with match scores, deadlines, and alerts so nothing slips past a submission date.
Each initiative you seek funding for gets its own workspace, and proven section templates mean you never start a response from a blank page.
Grantboost is an AI grant writing workspace aimed at organizations that fundraise through grants. Instead of juggling spreadsheet trackers, RFP databases, and generic writing tools, it brings discovery and drafting together: the platform continuously monitors sources such as grants.gov, foundation databases, and state portals, then scores each opportunity against your programs so you see the strongest matches first.
A distinguishing part of the product is voice training. You upload past proposals, annual reports, or simply paste your website URL, and Grantboost builds a profile of your mission, programs, and tone. Drafts are then generated section by section from that profile, with best-practice templates available for each part of a proposal so you are not starting from a blank page.
Around the drafting core, Grantboost provides a fundraising workspace: a pipeline view of every grant with deadlines and match scores, separate workspaces for each project or program you are seeking funding for, and team seats on higher tiers so colleagues can collaborate. Pricing scales with the number of active projects rather than the volume of AI usage, which is unlimited on paid plans.
Scan millions of sources for grants that fit your mission, score the best fits, and track each one through discovery, drafting, and submission in a single pipeline.
Manage separate project workspaces for each client, train each one's brand voice once, and reuse templates to shorten turnaround on every application.
Surface federal and foundation programs aligned with research priorities, then draft structured narratives that match each funder's required sections.
Start from templates and voice-trained drafts, then refine responses so applications sound specific and human rather than generic AI output.
