Overview

Grantboost is an AI grant writing tool that finds funding opportunities and helps draft the applications in the same place. It is built for nonprofits, grant-writing agencies, consultants and university research offices pursuing federal and foundation funding.

Grantboost positions itself against discovery-only tools. Finding a grant and writing a competitive application are separate efforts, and the second is where small organisations run out of capacity. A nonprofit that finds ten eligible grants but can staff only two applications has a drafting bottleneck, not a discovery one.

Grantboost offers separate paths for nonprofits writing for their own cause, agencies serving several clients, and university research teams. Funders’ requirements are exacting: a draft that misses a stated criterion can be disqualified however well it reads. Treat the output as a first draft and check it against the funder’s own guidelines before you submit.
