A note before starting: You do need to have a paid ChatGPT plan to do this. Currently that will run you $20/month.
In an age of limited staff and overwhelming demands, many nonprofit professionals are discovering that artificial intelligence (AI) can be a game-changer. Among the most versatile AI tools available is OpenAI’s Custom GPT, a way to tailor a version of ChatGPT to fit the specific voice, needs, and goals of your nonprofit organization.
This blog will guide you step-by-step through how to set up a Custom GPT, what kinds of data you need to make it effective, and how you can put it to work to support your marketing and fundraising goals.
Why Custom GPTs Are Valuable for Nonprofits
Most nonprofits operate with lean teams and juggle many priorities. Custom GPTs offer a way to automate repetitive tasks, improve communication, personalize donor outreach, and even generate compelling content on demand. Instead of starting from scratch every time, you can train your GPT to understand your organization’s mission, language, and audience.
Some examples of what a nonprofit Custom GPT can do:
- Write donor thank-you letters in your brand voice
- Draft newsletters or campaign copy based on previous examples
- Answer frequently asked questions from donors or volunteers
- Suggest subject lines, social posts, or calls to action
- Provide fundraising coaching for newer staff
- Translate your services or impact into donor-facing language
A well-trained Custom GPT is like a super-smart communications intern who never sleeps and never misses a deadline.
What You Need Before You Start
To get the most out of your Custom GPT, it’s critical to feed it the right information up front. Think of it as onboarding a new team member: the more context you give, the better the results.
Here’s what to gather before you build:
Essential Documents & Data to Upload:
- About Us language: mission, values, elevator pitch
- Recent appeal letters: at least 3-5 examples
- Thank-you letters or stewardship copy
- Newsletter articles, blog posts, or press releases
- Website copy (especially program and impact sections)
- Voice and tone guidelines, if you have them
- Donor segmentation strategies or personas
- Lists of FAQs from donors or volunteers
- Fundraising calendars or campaign timelines
The goal is to train your GPT on both your content and your style, so it learns to speak as you do. If you don’t have written guidelines, upload good examples of real work.
Step-by-Step: How to Set Up a Custom GPT
Here’s a simplified guide to creating a Custom GPT with OpenAI:
- Go to the ChatGPT app or chat.openai.com.
- Click “Explore GPTs” on the left menu, then “Create a GPT.”
- Walk through the GPT Builder wizard. This includes:
- Naming your GPT
- Choosing a profile picture and greeting message
- Setting instructions for how it should behave (e.g., “Write like a warm, accessible nonprofit storyteller.”)
- Uploading files, documents, and links
- Defining capabilities (e.g., should it generate text only? Browse the web?)
- Save and test your GPT. Try a few prompts: “Write a thank-you letter to a $100 donor” or “Draft a Giving Tuesday appeal for families.”
- Refine as needed. If your GPT misses the mark, update the files or instructions to be more specific.
The process takes less than an hour if you’ve prepared your materials.
Making It Work for Marketing & Fundraising
Once your GPT is trained, here are some high-impact ways to use it:
1. Fundraising Support
- Appeal writing: Draft seasonal or themed fundraising letters
- Donor segmentation: Tailor messages for different audiences
- Impact summaries: Translate program stats into donor-friendly language
- Thank-you copy: Generate variations of acknowledgment letters
2. Marketing Content Creation
- Social media posts: Based on your campaign goals or events
- Email newsletters: Pull in tone and structure from past emails
- Website updates: Summarize reports or program changes
- Event promotion: Draft invitations, reminders, and follow-ups
3. Internal Efficiency
- Template generation: Create editable copy blocks for staff
- Volunteer FAQs: Answer common questions consistently
- Messaging alignment: Ensure staff stay on brand in communications
Best Practices for Success
Be specific in your instructions. Instead of saying “write an appeal,” say “write a 3-paragraph appeal for animal lovers in their 40s who gave last year.”
Start with short prompts. See how the GPT responds before asking for long pieces.
Teach it what “good” looks like. Upload examples of content that worked well.
Keep it updated. Refresh your data every few months to reflect new campaigns or tone shifts.
Make it part of your workflow. Use it as a starting point, not a replacement. Think of it as a brainstorming partner.
Final Thoughts
A Custom GPT is not magic. But it is a powerful tool that, when trained with intention, can save time, boost creativity, and help your small team feel a little bigger. For nonprofits juggling impact, fundraising, and storytelling, a GPT that understands your voice is like hiring another you — without the need for coffee breaks.
Start small. Train it well. And soon, you’ll wonder how you ever worked without it.
