FunWithText – Free browser PII sanitizer and prompt injection scanner

Runs fully in the browser for regex-based redaction of structured PII (emails, cards, phones, API keys, IPs, SSNs) and offers an optional Claude step to catch names/addresses patterns miss. Clear placeholders like [NAME] and a privacy toggle make it practical for quick, manual workflows, and I like the Norwegian NIN/phone support. It's useful and thoughtfully privacy-first but not novel — the real win would be integrations (batch processing, editor/extension) or independent accuracy metrics for the AI step.
