For quick emphasis inside a conversation, Markdown Bot (@bold) is the better pick: it is Telegram's own inline bot, so you type @bold and your text in any chat, groups included, and send it as bold, italic or monospace without leaving the conversation and without ads. Its limit is those three styles. Text4Insta (@Text4InstaBot) works on a whole paragraph instead: you send it text in a private chat and copy back a version with centred lines, first-line indentation or struck-through words; about 29,000 people use it each month. Choose Text4Insta when you are preparing a long Instagram caption or channel post that should not read as a wall of text.

Official inline formatter: type @bold and your text in any chat to send it as bold, italic or monospace without markdown syntax. Free, instant, works everywhere.
Formats a wall of text into readable paragraphs — centred text, indented first lines, and strikethrough — aimed at Instagram-style captions, but just as useful for a Telegram channel post. Free, 29k+ monthly users.
