ChatGPT GPT Builder Welcome Message: Examples & Setup

You built a custom GPT. You wrote careful instructions. Then you left the greeting on whatever the GPT Builder suggested, and now the first thing every user sees is four generic prompts that sound like every other bot in the store.

The welcome message is the one field almost everyone leaves on default. It is also the first impression, the tone-setter, the moment a conversation decides whether it sounds like you or like a help desk.

This guide covers exactly where the welcome surface lives in GPT Builder, what it controls (and what it doesn't), and copy-paste examples that turn a generic opening into one that carries your voice. OpenAI's creating a GPT guide is the official reference for the builder itself.

Where the Welcome Message Lives in GPT Builder

First, a clarification that saves a lot of confusion: ChatGPT's GPT Builder has no field literally named "welcome message." People search for it because they expect one. What actually exists is two fields that together form the greeting.

Open the GPT Builder from Explore GPTs → Create, then switch to the Configure tab. You will see these fields:

• Name
• Description
• Instructions
• Conversation starters
• Knowledge
• Capabilities (web search, image generation, code interpreter)
• Actions

The "welcome message" is a combination of two of them:

1. Description: a short summary that shows under the GPT's name on the start screen, and in the GPT Store listing before anyone opens it.
2. Conversation starters: example prompts that appear as clickable buttons when a user opens the GPT.

That is your greeting. The Description tells people what this GPT is. The starters show them how to begin. Between them, they set the register of everything that follows.

For the field that does the heavy lifting on how your GPT actually writes, see our complete guide to custom GPT instructions. This post is about the surface people meet first.

What the Welcome Surface Controls (and What It Doesn't)

Here is the part most guides get wrong. The Description and the conversation starters do not work the same way behind the scenes.

The Description is human-facing. It is what your users read to decide whether to click. It shows on the start screen and in the Store. It is not injected into the model as a rule the way Instructions are. So think of the Description as your storefront sign, not your operating manual.

Conversation starters are model-facing, but only when clicked. A starter is not a hidden instruction that runs in the background. It sits there as a button. The moment a user clicks it, its exact text becomes their first message. The model reads it word for word, exactly as if the user had typed it.

That distinction matters more than it sounds. It means a conversation starter is voice-priming. The first user turn sets the tone of a chat, and here you get to write that first turn yourself. Leave it generic and the conversation opens in the default ChatGPT register. Write it in your voice and you have seeded the whole exchange before the user says a thing.

What the welcome surface does not do:

• It does not override your Instructions. If your Instructions say "write in short declarative sentences," that still governs every reply.
• It does not limit what users can ask. Starters are suggestions, not a menu. People can type anything.
• It does not change model behavior on its own. The Description is display copy. Only clicked starters reach the model.

So the mental model is simple. Instructions decide how the GPT writes. The welcome surface decides how the conversation opens. Both are voice surfaces. Most people only think about the first one.

Default vs Voiced: Side-by-Side Examples

The fastest way to see the difference is to compare. Here are common starters in their default, forgettable form next to a voiced version. Notice that the voiced version is not longer. It is more specific, and it sounds like a person.

Example 1: A writing-assistant GPT

• Default: "Help me write an email"
• Voiced: "Draft a reply that gets to the point in three sentences and skips the 'I hope this finds you well'"

Example 2: A strategy GPT for a founder

• Default: "Give me some business advice"
• Voiced: "Pressure-test this idea. Tell me the one reason it fails before you tell me why it works."

Example 3: A content GPT for a marketer

• Default: "Write a blog post"
• Voiced: "Turn these three bullet points into a post that opens with a problem, not a definition"

Example 4: A support GPT for a small team

• Default: "How do I use this product?"
• Voiced: "Walk me through setup like I've got five minutes and zero patience for jargon"

Example 5: A coding GPT

• Default: "Help me debug my code"
• Voiced: "Read this function, tell me what it actually does, then tell me what it's supposed to do"

The default versions are safe and dead. The voiced versions carry a register: direct, a little impatient, allergic to filler. They tell the user, before anything else happens, that this GPT has a personality. And because the clicked text becomes the real first message, they also tell the model how to answer.

The Description works the same way. Compare:

• Default: "A helpful assistant for writing emails."
• Voiced: "Writes emails the way you'd write them if you had ten more minutes and no meetings."

Same length. One is a label. The other is a voice.

Templates by Use Case

Use these as starting points. Fill in the specifics from your own work, then edit the phrasing until the starters read like something you would actually type. Remember: only your first four starters show as buttons, so lead with your strongest.

Personal writing twin GPT

• Description: "Drafts in [your name]'s style: direct, short sentences, no corporate filler."
• Starters:
  1. "Draft a reply to this email in my voice, three sentences max"
  2. "Rewrite this so it sounds like me, not like a press release"
  3. "Turn these notes into a message I'd actually send"
  4. "Make this shorter without making it cold"

Team or client-facing GPT

• Description: "Writes updates and proposals in our house style, ready to send."
• Starters:
  1. "Draft a weekly update: wins first, blockers second, no fluff"
  2. "Write a client email that says no without sounding defensive"
  3. "Summarize this thread in five bullets a busy exec will read"
  4. "Rewrite this in our tone: plain, confident, specific"

Creator or content GPT

• Description: "Turns rough ideas into posts that open strong and skip the throat-clearing."
• Starters:
  1. "Open this post with a problem, not a definition"
  2. "Give me three hooks for this topic, no clickbait"
  3. "Rewrite this intro so it earns the next sentence"
  4. "Cut this by a third and keep the rhythm"

The pattern across all three: every starter is a complete, ready-to-run prompt written in the register you want. That is the whole trick. A starter is a free sample of how this GPT talks.

If you want the underlying voice to be consistent everywhere (not just in the opening), the real work happens in the Instructions field. Our guide on building custom instructions that capture your voice walks through that in depth, and our full ChatGPT Style Profile workflow covers deploying the same voice across every ChatGPT surface.

A voiced welcome message is a good start. A voiced welcome message on top of a real Style Profile is a GPT that sounds like you from the first click to the last reply.

Frequently Asked Questions

What is the welcome message in a custom GPT?

There is no field literally labeled "welcome message" in GPT Builder. The greeting your users see is built from two things: the Description (a short summary shown on the start screen and in the GPT Store) and the Conversation starters (example prompts shown as clickable buttons). Together they form the welcome surface people read before they type.

Do conversation starters affect responses?

Yes, but only when clicked. A conversation starter is not a hidden system prompt. When a user clicks one, its exact text becomes their first message, so the model reads it word for word. A starter written in your voice seeds the register of the whole conversation. A starter left on default seeds a generic one. Your Instructions still govern how every reply is written.

How many conversation starters can you add?

You can add more than four in the Configure tab, but only four appear as clickable buttons on the GPT's start screen (on desktop). Treat those first four as prime real estate: your four best, most voiced prompts, not filler.
