Your inputs stay in this page. Only the tool name is sent to record a successful use. No account needed.
Common questions
What limitations apply?
Input is treated as plain text. Decoded markup is displayed as text, never inserted as executable HTML.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
