Building Custom GPTs for Your Newsroom or Brand
Custom GPTs let you create a specialized AI assistant pre-loaded with your publication's style guide, your beat knowledge, and your preferred workflows. Instead of re-explaining your context in every conversation, you build it once and use it forever. This lesson shows you how.
What You'll Learn
- What Custom GPTs are and why they're valuable for media professionals
- How to build a Custom GPT tailored to your journalism or content workflow
- Five Custom GPT ideas specifically for journalists and content creators
- How to share Custom GPTs with your team or newsroom
What Are Custom GPTs?
Custom GPTs are personalized versions of ChatGPT that you create through OpenAI's GPT Builder (available with ChatGPT Plus). They allow you to:
- Pre-load instructions so you don't re-type your style guide, audience, and preferences every time
- Upload reference documents like your publication's style guide, past articles, or source databases
- Define specific behaviors like always citing sources, never using passive voice, or formatting output in a specific way
- Share with your team so everyone in your newsroom or content operation uses the same AI assistant
Think of it as training a dedicated AI intern who already knows your publication, your beat, and your standards.
Building Your First Custom GPT
Step 1: Define the Purpose
Before opening the GPT Builder, answer these questions:
- What specific task will this GPT handle? (Be narrow -- "research assistant for my education beat" is better than "journalism helper")
- What context does it need? (Your publication, audience, style guide, beat expertise)
- What should it always do? (Cite sources, match your tone, flag uncertainties)
- What should it never do? (Invent quotes, use certain phrases, write more than a specified length)
Step 2: Write the Instructions
Here's a template for a journalism-focused Custom GPT:
You are a [specific role] for [publication name].
ABOUT THE PUBLICATION:
- [Publication name] covers [beat/topic] for [audience description]
- Our tone is [description -- e.g., "authoritative but accessible, like The Atlantic meets Wired"]
- Average article length: [word count range]
- We follow [AP Style / Chicago Manual / custom] for grammar and formatting
YOUR ROLE:
- [Primary task 1 -- e.g., "Help research and outline articles about education policy"]
- [Primary task 2 -- e.g., "Generate headline options for articles I've written"]
- [Primary task 3 -- e.g., "Repurpose articles into social media content"]
RULES YOU MUST FOLLOW:
- Never invent facts, statistics, or quotes
- Always flag claims you're uncertain about with [UNVERIFIED]
- Match the publication's tone and style in all output
- When suggesting sources, prioritize [types of sources relevant to your beat]
- Keep all output under [word limit] unless I ask for more
- [Any other rules specific to your workflow]
THINGS YOU SHOULD NEVER DO:
- Never use [list banned phrases or clichés from your style guide]
- Never generate content that could be mistaken for a direct quote from a source
- Never skip citation or attribution
Step 3: Upload Reference Documents
The GPT Builder lets you upload files. For journalists and content creators, the most useful uploads are:
- Your publication's style guide (PDF or document)
- 5-10 of your published articles (so it learns your voice)
- A glossary of beat-specific terminology
- Your content calendar template
- A list of frequently referenced sources or organizations
Step 4: Test and Iterate
After building your GPT, test it with real tasks:
- Ask it to outline an article you've already written (compare to your actual outline)
- Ask it to write in your style (compare to your actual published work)
- Try an edge case (ask it to do something outside its scope -- it should refuse gracefully)
- Check that it follows your rules (try to get it to invent facts -- it should flag uncertainty)
Refine the instructions based on what works and what doesn't.
Five Custom GPT Ideas for Media Professionals
1. Beat Research Assistant
Purpose: Quickly background any topic on your beat
Instructions focus: Pre-loaded with knowledge of your beat, key organizations, recurring debates, and your preferred source types. When you say "background me on [topic]," it produces a structured research brief.
2. Style-Matched Editor
Purpose: Edit drafts to match your publication's standards
Instructions focus: Upload your style guide and sample articles. It edits for tone, grammar, AP Style compliance, and house style. It catches inconsistencies and suggests improvements.
3. Social Media Content Creator
Purpose: Turn articles into platform-specific social content
Instructions focus: Pre-loaded with your social voice (which may differ from your article voice), platform-specific rules (character limits, hashtag strategy), and your content pillars. Feed it an article, get a week of social posts.
4. Interview Prep Assistant
Purpose: Prepare questions and background for interviews
Instructions focus: Given a name and topic, it researches the person, identifies their known positions, surfaces past interviews, and generates targeted questions. Pre-loaded with your interviewing philosophy and the type of questions your publication values.
5. Newsletter Curator
Purpose: Help compile and write your weekly newsletter
Instructions focus: Knows your newsletter format, tone, and recurring sections. You feed it your weekly links and notes, it produces a draft newsletter in your exact format with your voice.
Sharing Custom GPTs With Your Team
If you work in a newsroom or content team:
- GPT Builder lets you publish GPTs as "Anyone with the link" or within your ChatGPT Team workspace
- Create role-specific GPTs -- a research GPT for reporters, an editing GPT for editors, a social GPT for the social media team
- Document how to use each GPT -- Include example prompts and expected outputs
- Assign someone to maintain them -- Style guides change, beats evolve. Someone needs to update the instructions periodically
Beyond ChatGPT: Claude Projects
If you use Claude (Anthropic), a similar feature called Projects allows you to:
- Upload documents for persistent context
- Set custom instructions that apply to every conversation in the project
- Organize different workflows into separate projects
The principles are the same: define the purpose, provide context, set rules, and test thoroughly.
