Short answer: United Way of West Central Connecticut used a custom AI, built by The Endurance Group (TEG) from its own grant files and website, on a real grant within a month of the first draft.

United Way of West Central Connecticut is a Bristol-based chapter serving Bristol, Burlington, Plainville and Plymouth. Its small resource development team applies for grants while running events like the annual golf tournament and a back-to-school supply drive.

Grant writing at a small nonprofit is mostly reuse. The language already exists in past applications, reports and decks. The work is finding it, fitting it to each funder's form, and doing it again for the next deadline.

Board member Trish Tomlinson introduced TEG's Conor Sullivan to the team to explore how AI could help.

TEG asked for the documents a new grant writer would want on day one: reports, one-pagers, decks and previous grant applications. The team shared them in a Google Drive folder, and a first draft of the AI reached them the same day. It draws on:

  • The United Way's previous grant applications and supporting documents
  • The organization's public website
  • More files from the team as the project went on, so answers improve with more information

Conor asked the team to question it and flag anything that seemed off. They chose a small grant due in a few weeks as a real-life test.

"This is wild and so incredibly helpful."

Sarah Mitchell, Resource Development Coordinator, United Way of West Central Connecticut

Within a month, the team had used the AI on a real grant.

"We’ve used it for one grant already and it was a great help."

"The Endurance Group helped us create an AI that allowed us to apply for grants much more efficiently than before. Their expertise and innovative approach have streamlined our grant application, saving us invaluable time and resources."

How can a nonprofit use AI for grant writing?

Start with the organization's own approved material, give the AI only that, and test it on a real deadline. That is what worked here:

  • Ground it in your own files: past applications, reports, decks and your website
  • Test it on a live grant, not a demo
  • Keep adding material, so answers improve over time
  • Keep a person responsible for everything that gets submitted
