AI Talks Markdown (By Default)

Part of the Fundamentals section of Coddy's AI Prompts journey — lesson 13 of 23.

When you ask the AI a question, you might notice something about its responses: they often include bold text, bullet points, numbered lists, and headers. This isn't random—the AI naturally responds using Markdown, a simple formatting language.

Markdown is a way to add structure to plain text.

When the AI writes **important**, it appears bold. When it writes - item, you see a bullet point. The chat panel automatically renders this formatting so it looks clean and organized.

This default behavior has consequences. Ask the AI to explain something, and you'll likely get headers, lists, and emphasized words—even if you just wanted a simple sentence. The AI assumes structure helps, so it adds it automatically.

For example:

Breakdown this: 13 * 43 = ?

You'll probably get something like:

Breaking down the multiplication:
13 × 43
We can break it into smaller parts for easier calculation:

13 × 40 = 520
13 × 3 = 39

Adding these results together:
520 + 39 = 559
So, the result of 13×4313×43 is 559.

That's Markdown at work. Sometimes this formatting is exactly what you want. Other times, it's overkill for a simple answer. The good news: you can control this. In the next lesson, you'll learn how to tell the AI exactly what format you need.

Challenge

Ask the AI to break down and solve this math problem step by step: "If you buy 3 books at $12 each and pay with $50, how much change do you get?"

The AI's response must:

Contain bold text (**)
Contain the number 14

Notice all that formatting? You didn't ask for bold text or bullet points. AI models automatically add Markdown formatting. In later lessons, you'll learn how to control this.

Cheat sheet

AI models naturally respond using Markdown, a simple formatting language that adds structure to plain text.

Common Markdown formatting that AI automatically includes:

**text** appears as bold text
- item creates bullet points
Headers and numbered lists for organization

This formatting happens by default—even when you ask simple questions, the AI often structures responses with headers, lists, and emphasized words.

Example prompt:

Breakdown this: 13 * 43 = ?

The AI will likely respond with structured formatting including bold numbers, bullet points breaking down the calculation, and emphasized results—not just a simple answer.

This automatic formatting can be helpful for complex explanations, but may be excessive for simple queries. You can control this behavior by specifying the format you want in your prompts.
