Twenty-three text styles you can paste into Bluesky — with a straight answer about what they cost.
Free, no sign-up, and it runs entirely in your browser. Limits checked 2026-08-31.
These are maths symbols, not formatting.
They look like bold or italic text and they are separate characters with separate meanings. Screen readers usually either read them out as symbol names — “mathematical bold small e”, once per letter — or skip them entirely, so a blind reader may hear nothing at all. They are also excluded from search on X and LinkedIn, are not translated, and will not linkify inside a hashtag.
Worth using for a word or two. Not worth using for a headline, a name, or anything you want found.
𝗬𝗼𝘂𝗿 𝘁𝗲𝘅𝘁 𝗵𝗲𝗿𝗲
The one most people mean. Best coverage of any bold style.
𝘠𝘰𝘶𝘳 𝘵𝘦𝘹𝘵 𝘩𝘦𝘳𝘦
The least-covered of the eight math faces — boxes on some Android builds.
𝙔𝙤𝙪𝙧 𝙩𝙚𝙭𝙩 𝙝𝙚𝙧𝙚
Same coverage gap as italic.
𝐘𝐨𝐮𝐫 𝐭𝐞𝐱𝐭 𝐡𝐞𝐫𝐞
𝑌𝑜𝑢𝑟 𝑡𝑒𝑥𝑡 ℎ𝑒𝑟𝑒
𝒀𝒐𝒖𝒓 𝒕𝒆𝒙𝒕 𝒉𝒆𝒓𝒆
𝖸𝗈𝗎𝗋 𝗍𝖾𝗑𝗍 𝗁𝖾𝗋𝖾
𝚈𝚘𝚞𝚛 𝚝𝚎𝚡𝚝 𝚑𝚎𝚛𝚎
Looks like a typewriter font but is not actually fixed-width — no good for columns.
𝕐𝕠𝕦𝕣 𝕥𝕖𝕩𝕥 𝕙𝕖𝕣𝕖
Capitals render everywhere; lowercase drops out on some Android builds.
𝒴ℴ𝓊𝓇 𝓉ℯ𝓍𝓉 𝒽ℯ𝓇ℯ
Eleven letters come from a different font, so the run often looks uneven even when nothing is missing.
𝓨𝓸𝓾𝓻 𝓽𝓮𝔁𝓽 𝓱𝓮𝓻𝓮
𝔜𝔬𝔲𝔯 𝔱𝔢𝔵𝔱 𝔥𝔢𝔯𝔢
Five capitals come from a different font. Carries unfortunate historical associations in some markets.
𝖄𝖔𝖚𝖗 𝖙𝖊𝖝𝖙 𝖍𝖊𝖗𝖊
ʏᴏᴜʀ ᴛᴇXᴛ ʜᴇʀᴇ
X and Q have no small-capital form in Unicode, so they stay full height.
Ｙｏｕｒ ｔｅｘｔ ｈｅｒｅ
The most reliable style here — every CJK font has these.
Ⓨⓞⓤⓡ ⓣⓔⓧⓣ ⓗⓔⓡⓔ
Ⓜ renders as the metro emoji on some phones.
🅨🅞🅤🅡 🅣🅔🅧🅣 🅗🅔🅡🅔
No lowercase exists, so lowercase borrows the capital. Digits come from a different design.
🅈🄾🅄🅁 🅃🄴🅇🅃 🄷🄴🅁🄴
No lowercase or digits exist. Missing from many Android builds.
🆈🅾🆄🆁 🆃🅴🆇🆃 🅷🅴🆁🅴
A, B, O and P are also emoji and go colour on most phones while the other 22 stay monochrome. Expect a mismatched run.
ʸᵒᵘʳ ᵗᵉˣᵗ ʰᵉʳᵉ
A handful of letters have no superscript form that any font actually ships, and are left as they are.
Y̶o̶u̶r̶ ̶t̶e̶x̶t̶ ̶h̶e̶r̶e̶
A combining mark after each letter. The line is always a little ragged — that is the font, not the tool.
Y̲o̲u̲r̲ ̲t̲e̲x̲t̲ ̲h̲e̲r̲e̲
As with strikethrough, the line is drawn per character and will look uneven.
ǝɹǝɥ ʇxǝʇ ɹno⅄
Reversed as well as flipped, so it reads bottom-right to top-left. Unintelligible to a screen reader.
Bluesky gives you no formatting toolbar, so what everybody actually does is substitute characters that look bold or italic. They come from the Mathematical Alphanumeric Symbols block, encoded so that a paper can tell the vector 𝐱 from the scalar x.
The substitution is not simple arithmetic. Unicode left twenty-four holes in that block's Latin range — letters that already existed elsewhere — so a generator that just adds an offset produces unassigned codepoints, which render as empty boxes. Every hole is patched here, and a script in the repository asserts that no style can emit an unassigned character.
Text you paste in is turned back into plain letters before a style is applied, so switching between styles works instead of silently doing nothing.
Mostly, and not entirely. These are real Unicode characters, so any app can display them if its font has them — and some fonts do not. Each style on this page is labelled with how widely it renders; the ones marked as risky are missing from enough Android font stacks that a real share of readers will see empty boxes instead of letters.
Because these are not the letters they look like. A search for “marketing” does not match the mathematical characters that spell it in bold, so a styled headline is invisible to search on X and LinkedIn, a styled hashtag never becomes a hashtag, and translation tools pass the whole thing through untranslated. If the words matter, leave them plain.
Yes, and that is not a hedge. Screen readers either announce these characters by name — “mathematical bold small e”, once per letter — or skip them entirely, so a blind reader hears either nonsense or silence. Braille displays have no mapping for most of them. Use a styled word or two for emphasis if you like; do not put your name, your headline, or the point of the post in them.
You can, and it is the one place we would tell you not to. A name in styled characters cannot be found by anybody searching for you, cannot be read aloud by a screen reader, and on LinkedIn a decorated name is a documented reason for a profile to be restricted. Style a word inside a post if you want emphasis; leave your name alone.
Nothing. There is no server behind these pages — the tool is JavaScript running in your tab, so what you type stays in the browser and is never sent anywhere, by us or by anyone else.
Free, with no sign-up, no limit and no watermark. These tools cost us nothing to run because they run on your computer rather than ours. We build them because the people who need them are the people who might eventually want the product they sit next to — that is the whole arrangement, and it does not require anything from you.
Reaching for fake bold usually means a post is hard to scan. Influenar writes drafts against your brand kit — your voice, your style rules, your source material — so the structure does the work that formatting was being asked to.
