Does this count emojis and links the same way each platform does?

Yes — different networks count emojis and URLs differently (some count a shortened link as a fixed number of characters regardless of its real length), and this tool applies each platform's actual counting rules rather than a simple character-by-character count.

Which network has the shortest limit I need to worry about?

X is typically the tightest at 280 characters for most accounts, which is why it's a common benchmark — a caption that fits X comfortably usually fits everywhere else too.

Is anything I type here sent to a server?

No — counting happens entirely in your browser, so nothing you paste or type is transmitted or stored anywhere.

Paste your caption and watch it measured against every network at once — characters, words and lines counted live, and each limit lit until you blow it.
