Idea: a fully local (offline) tool that masks sensitive data before you send anything to AI tools (ChatGPT, Gemini, etc.).

Key things:

• No backend — nothing leaves your machine
• Users define their own rules (regex / keywords)
• Select text → “Clean” → PII gets masked
• Can also paste text in extension

Extra features I’m exploring:

• Upload PDF → extract text + mask PII
• Upload image → detect text + mask
• Custom rule upload (so it works across industries/countries)

Example:
“John from Acme email is john@gmail.com”
→ “[NAME_1] from [ORG_1] email is [EMAIL_1]”

Questions:

• Would you actually use this?
• Is custom-rule approach better than auto detection?
• PDF/image support useful or overkill?

Looking for blunt feedback 🙏
