How Social Character Limits works

The counter or converter is a loop over the characters you typed, running in this tab. There is no draft to sync, no spell-check service and no copy of your writing anywhere but your own screen. Paste a confidential paragraph and it is treated like a local variable: created when you type, discarded when the tab closes.

That is the whole architecture: static files, one script, no upload endpoint to leak or log. Close the tab and the work is gone.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
