# Building an emoji list generator with the GitHub Copilot CLI

See how we created an emoji list generator during the Rubber Duck Thursday stream.

Every week, the GitHub team runs[a stream called Rubber Duck Thursdays](https://www.youtube.com/@GitHub/streams), where we build projects live, cowork with our community, and answer questions!

This week, we built a very fun project together using the[GitHub Copilot CLI](https://github.com/features/copilot/cli?utm_source=blog-rdt-emoji-list-cta&utm_medium=blog&utm_campaign=dev-pod-copilot-cli-2026)! Let me tell you about it.

![Image 28: 💡](https://s.w.org/images/core/emoji/17.0.2/svg/1f4a1.svg)_New to GitHub Copilot CLI?[Here’s how to get started.](https://github.blog/ai-and-ml/github-copilot/github-copilot-cli-for-beginners-getting-started-with-github-copilot-cli/)_

## What is it?

In a lot of social media tweets and launches, you often see accounts post things like:

```plaintext
We shipped the most amazing emoji list generator ever. It:

 Works in the CLI
 Uses the Copilot SDK to intelligently convert your bullet points to relevent emoji
 Copies the result to the clipboard
```

It’s beautiful. But coming up with the perfect emoji is far too slow for me in this “move fast and break things” world. I have projects to build! Repos to vibe! Pull requests to merge! I can’t be thinking about emojis!

And thus, on the stream, we build an emoji list generator (very descriptively called Emoji List Generator) that:

![Image 29: 🖥️](https://s.w.org/images/core/emoji/17.0.2/svg/1f5a5.svg) Runs in the terminal

![Image 30: 📋](https://s.w.org/images/core/emoji/17.0.2/svg/1f4cb.svg) You paste or write a list

![Image 31: ⌨️](https://s.w.org/images/core/emoji/17.0.2/svg/2328.svg) You hit Ctrl + S

![Image 32: 📎](https://s.w.org/images/core/emoji/17.0.2/svg/1f4ce.svg) You get the list on your clipboard

(Can you tell I’m dogfooding the product here?)

## How we built it

We used a few cool technologies for this project:

![Image 33: 🖥️](https://s.w.org/images/core/emoji/17.0.2/svg/1f5a5.svg)`@opentui/core`for the terminal UI

![Image 34: 🤖](https://s.w.org/images/core/emoji/17.0.2/svg/1f916.svg)`@github/copilot-sdk`for the AI brain

![Image 35: 📋](https://s.w.org/images/core/emoji/17.0.2/svg/1f4cb.svg)`clipboardy`for clipboard access

To start the project off, we opened up the GitHub Copilot CLI.

In plan mode using Claude Sonnet 4.6, we wrote:

```plaintext
I want to create an AI-powered markdown emoji list generator. Where, in this CLI app, if I paste in or write in some bullet points, it will replace those bullet points with relevant emojis to the given point in that list, and copies it to my clipboard. I'd like it to use GitHub Copilot SDK for the AI juiciness.
```

Copilot asked me a bunch of clarifying questions, for example around the tech stack and what libraries we should use (shoutout to[Gabor](https://javorszky.co.uk/)in the chat for suggesting[OpenTUI](https://opentui.com/)), and from there, we had a fully thought-out`plan.md`file for me to review and use!

We implemented the plan using Claude Opus 4.7 (which was[recently released](https://github.blog/changelog/2026-04-16-claude-opus-4-7-is-generally-available/)!) and a few minutes later, voilà, we had a fun little terminal UI to work with!

![Image 36: Screenshot of the 'Emoji List Generator.' Paste or type your bullet points below. Press CTRL + S to generate, CTRL + C to quit.

Your bullet points
- Is there a ghost here?
- Ducks quack a lot
- I would like to have a word with the moon
- Mechanical keyboards are cool
- We just launched a sick new feature
- I'd like to squish some slime

Followed by the same list, with appropriate emojis.](https://github.blog/wp-content/uploads/2026/04/list.png?resize=1869%2C1944)
The project was small but mighty. In the CLI, we used some really cool tools all together:

![Image 37: 📋](https://s.w.org/images/core/emoji/17.0.2/svg/1f4cb.svg)[Plan mode](https://docs.github.com/copilot/how-tos/copilot-cli/cli-best-practices?utm_source=blog-rdt-emoji-list-cta&utm_medium=blog&utm_campaign=dev-pod-copilot-cli-2026#plan-mode)
