Case converter
Paste text and pick a case. A URL, a hashtag and an @mention are found first and left exactly as typed; only the surrounding text is converted.
Converted as you type, in this tab. Nothing is uploaded or stored.
Result
Type or paste text to see it converted.
What stays untouched
Every http or https link, every #hashtag and every @mention is detected before any conversion runs, and none of the four modes touches them: a link is case sensitive in its path, a hashtag is how a platform indexes a post, and a mention names a real account. Title Case here means one fixed rule, capitalize the first letter of every remaining word and lowercase the rest, without the list of lower-cased small words some house styles use, because this tool has no basis to make that editorial call for you.

常見問題
Does this change my links or hashtags?
No. Every URL, #hashtag and @mention is detected first and copied through unchanged in every mode, including sentence case, which still capitalizes the real sentence text around them.
How does Title Case decide what to capitalize?
It capitalizes the first letter of every word outside a protected link, hashtag or mention, and lowercases the rest of that word. It does not lowercase short connecting words such as "a" or "of" the way some house style guides do, since that is a style choice rather than a fact this tool can make for you.
我的草稿會被上傳嗎？
不會。此檢查在你的瀏覽器中運作，沒有任何請求會帶走你的文字，不會儲存任何內容，關閉分頁就足以將它捨棄。
這個工具能幫我發布嗎？
目前還不行。尚無任何連接器完成供應商驗證，因此此網站目前尚未透過任何工具發布到任何平台。此頁面是限制檢查工具，而非撰寫工具。
