X strips formatting, so the only way to get bold or italic into a post is to swap the letters themselves for Unicode lookalikes. Type below and get your text in eighteen styles, each with its own copy button, along with the two things most fonts tools will not tell you: styled characters cost double against the 280 limit, and screen readers struggle with them, so style a few words, never the whole post.
Every style updates as you type, in your browser. Copy the one you want and paste it straight into the composer.

The other room
The X tools on this site run entirely in your browser. The LinkedIn half goes much further: Depost AI is an AI content team for B2B founders and teams, agents that read your analytics, plan your week, draft in your voice, design the graphics, and publish through the official API. If LinkedIn is part of your mix, that half can run itself.
Emphasis is the honest use case. One bolded phrase in a plain post directs the eye the way bold does anywhere else, and on a platform with no native formatting that is a real advantage. The failure mode is the fully styled post, which costs you three ways at once: it reads as decoration rather than emphasis, it doubles your character spend since these ranges are weighted 2 on X, and it locks out readers using assistive technology, who hear a string of maths symbols where your sentence was.
The maps behind this page handle the detail that trips up most fonts tools: Unicode assigned some letters of these alphabets long before the rest, in other blocks, so a naive offset produces the occasional unassigned box mid-word. Every one of those holes, the script H, the gothic C, the outline R and friends, is patched to its proper code point here, which is why the output holds up letter for letter.
LinkedIn strips pasted formatting just as thoroughly, and the same eighteen styles survive it the same way. The LinkedIn text formatter on this site applies them inside a full composer, with bullets, undo, and a feed preview, and it shares these exact character maps, so a style copied from either page is identical. Wherever you use them, the discipline carries over: emphasis, not decoration.
X Character Counter
The count the way X actually counts: every link is 23, and some characters cost double.
AI Tweet Generator
Three post options from a rough idea, each inside 280 characters, none of them engagement bait.

Bold, italic, and list formatting that survives the LinkedIn composer, which strips almost everything you paste into it.
