linkedin-formatter-tool — Yadui

LinkedIn Post Formatter adds a floating toolbar to LinkedIn's post, comment, and message editors. Select any text and instantly apply rich formatting styles that work within LinkedIn's plain-text environment using Unicode mathematical characters and combining diacritics.

Supported styles:
- Bold — mathematical bold Unicode characters
- Italic — mathematical italic Unicode characters
- Bold Italic — combined bold + italic
- Underline — combining underline diacritic
- Strikethrough — combining strikethrough diacritic
- Sans-Serif, Sans Bold, Sans Italic — clean alternate typefaces
- Monospace — fixed-width Unicode characters

How it works:
The toolbar appears automatically above your selected text when you highlight content inside any LinkedIn editor (post box, comment field, or message composer). Click a style button to instantly transform the selected text. Keyboard shortcuts are also supported: Ctrl+B for bold, Ctrl+I for italic, Ctrl+U for underline, and Ctrl+Shift+X for strikethrough.

No data is collected, no accounts required, and no external requests are made. The extension works entirely within your browser on linkedin.com.
