# Strikethrough in Markdown

> How to cross out text in Markdown with ~~tildes~~ — the GFM syntax, where it works, and what AI does with struck text.

## Basic syntax

Wrap text in two tildes on each side — that's strikethrough.

```markdown
~~no longer needed~~
```

## It's GFM, not core Markdown

Strikethrough isn't in the original Markdown. It comes from GitHub Flavored Markdown, so it works on GitHub, Slack, Discord, Notion and most modern editors — but not every renderer.

## Mix it with bold or italic

You can nest it. Wrap bold text in two tildes and it strikes and bolds at once.

```markdown
~~**struck and bold**~~
```

:::tip
For AI, struck text still gets read — it reads as "deprecated", not "deleted". If you truly want it gone, remove it.
