ChatGPT Callout Styler by Xanet

ChatGPT Callout Styler makes Markdown-style callouts easier to read inside ChatGPT.

It detects Obsidian-style blocks such as:

[!info] Information
Useful context or explanation.

[!success] Recommendation
A positive result or suggested action.

[!warning] Warning
Something that needs extra care.

[!danger] Risk
A critical issue or possible error.

The extension automatically turns those blocks into clean, colored callout boxes with a minimal Obsidian-inspired design.

How to use it:

Ask ChatGPT to use Obsidian-style callouts when it wants to highlight important notes. For example, you can add this to your Custom Instructions:

"When you want to highlight an important note, use Obsidian-style Markdown callouts:

[!info] Information
Useful explanation.

[!success] Recommendation
Recommended action.

[!warning] Warning
Something to be careful about.

[!danger] Risk or error
Critical information.

Use them only when they add clarity."

Features:

• Styles [!info], [!success], [!warning], [!danger], [!note], [!tip], [!question], [!example], and [!quote]
• Works directly on ChatGPT pages
• Uses lightweight CSS and JavaScript
• Does not require an account
• Does not collect, store, or send any personal data
• Free to use

This add-on is useful if you often ask ChatGPT to format important notes, recommendations, warnings, risks, or examples using Markdown callouts.
