write it once. select words and press B or I, or type **bold** and _italic_.
write or paste your post, and it shows up here ready to copy.
how to use it
- write or paste your post. leave an empty line between paragraphs: that's where a thread splits first.
- select the words you want to stand out and press B or I. you can also type **bold** and _italic_ yourself.
- on the X tab, copy each post into your thread, in order. on the LinkedIn tab, copy the whole post.
how the X thread is split
a post on X holds 280 characters, but X doesn't count every character as one. links always count as 23, however long they are. most emoji, Chinese, Japanese and Korean characters, and styled letters like 𝗯𝗼𝗹𝗱 count as 2. the counts here follow the same rules, so a post that fits here fits on X.
the thread breaks between paragraphs first, then between sentences, and only then between words, so each post reads on its own. numbering (1/4, 2/4…) is on by default and the room it takes is saved for it.
bold and italic on LinkedIn
LinkedIn has no formatting buttons in its posts. the bold and italic text people use are Unicode letters that look styled, and that's what this tool makes, so it shows up the same on the web and in the apps.
use them for a word or a short line: a whole post of styled letters is hard to read, and screen readers may read them oddly. the first lines matter most: LinkedIn shows about the first three lines or 210 characters, then “…see more”. the preview shows you exactly that.
what to post about what you ship
- lead with the change, not the work: “csv import is live” beats “spent the week on parsers”.
- say who it's for and why it matters in one or two lines.
- end with a link where people can try it, and what's next.
shipping every week? commiToday turns each update into its own public page, writes the posts from your GitHub commits, and keeps your build streak, so there's always something to share.
questions
+is it free?
yes. it runs in your browser, nothing you write is sent anywhere, and there's no sign-up.
+why does X count my post as longer than it looks?
X counts every link as 23 characters, and emoji, styled letters and Chinese, Japanese or Korean characters as 2. this tool counts the same way, so what fits here fits on X.
+does bold text work in LinkedIn posts and comments?
yes. the styled letters are ordinary Unicode, so they work in posts, comments, your headline and your about section.
+should I use bold on X too?
you can, by ticking “bold and italic on X too”. each styled letter counts as 2 on X, so keep it to a few words. it's off by default for that reason.
+what about X Premium's longer posts?
if you can post more than 280 characters, use the LinkedIn tab's text as one long post. the thread here is for the standard limit.
