Shipped: a privacy-first Character Counter with real platform rules

I’ve shipped Character Counter, the latest built-in tool in ToolkitLoop.

It counts visible characters rather than misleading underlying code units, so emoji, flags, and combined characters are handled more clearly. It also includes platform-aware checks for X, SMS, Instagram, LinkedIn, Facebook, Threads, Pinterest, and YouTube titles.

Like the rest of ToolkitLoop’s built-in tools, all counting happens locally in the browser. No account is required, and the text is not uploaded.

Try it: https://toolkitloop.com/character-counter/

I’d love feedback on which platform-specific writing limit would be most useful next.
