How to redact sensitive data before pasting into Claude or ChatGPT
Runs 100% locally in your browser · Zero uploads · Free
Summary
Instead of uploading private contracts, emails, HR notes, or logs to a cloud redaction server, Yaqgu Redact for AI cleans text locally in your browser tab via WebAssembly and on-device name detection, lets you paste safely into Claude, ChatGPT, or Gemini, and restores original names when you paste the answer back.
1. The 3-step local workflow
- Paste or drop locally: Paste raw text or drop a
.pdf,.docx,.csv,.json,.log, or code file into Redact for AI. - Review & copy safe text: Sensitive values become consistent tokens like
[PERSON_1],[ORG_1],[EMAIL_1], or[SECRET_1]. Click any highlight to toggle it, or select any phrase to hide it. - Restore on reply: Copy the safe text into Claude, ChatGPT, or Gemini, then paste the AI's reply back into Redact to swap the real values back in one click.
2. Local browser redaction vs alternatives
| Approach | Uploads raw text? | Restores AI reply? | Account needed? | Works offline? |
|---|---|---|---|---|
| Yaqgu Redact for AI | No (0 B sent) | Yes (in-tab) | No | Yes (after load) |
| Cloud PII proxy / SaaS | Yes (to proxy server) | Varies | Usually yes | No |
| Manual Find & Replace | No | Manual | No | Yes |
3. Supported files and sensitive details
Redact for AI reads plain text, text-based PDFs (.pdf), Word documents (.docx), spreadsheets (.csv, .tsv), configs and logs (.json, .log, .yaml, .env, .sql), and source code files—all inside your browser.
It detects names, companies, addresses, emails, phone numbers, payment cards, bank and UPI details, Aadhaar, PAN, SSN, passwords, IP/MAC addresses, and API keys. Automated detection is a helper and can make mistakes, so always review the output before pasting into any AI tool.
