7 Things You Should Never Paste Into ChatGPT, Claude, or Gemini — No Matter How Helpful It Seems

TamilTech AI summary

Hey, AI chatbots like ChatGPT, Claude, and Gemini feel private, but they are not—inputs can be visible to company staff, used for model training, or even become searchable after security flaws. That risk hits Indian users harder because everyday UPI, Aadhaar-linked services, IRCTC, and rapid AI adoption create extra ways financial and identity data can be misused. Never paste bank or card details, UPI IDs, passwords, OTPs, Aadhaar or PAN numbers, specific medical records, company secrets or source code, or other people’s personal info without consent. Ask general questions without real numbers, anonymize names, use enterprise AI plans for work, and turn off training in settings such as ChatGPT Data Controls or Gemini Apps Activity. Treat every prompt like a postcard someone else might read, so you still get everyday help while keeping sensitive data out.

• AI chatbots are 'public environments' — conversations may be used for training, stored on servers, and in documented cases indexed by search engines; treat every prompt like a postcard
• Never paste: bank details/UPI IDs, Aadhaar/PAN, passwords/OTPs, company-confidential data, medical records, other people's personal info without consent
• Turn off AI training now: ChatGPT → Settings → Data Controls → off; Gemini → Google Account → Gemini Apps Activity → pause; Claude → account privacy settings → opt out
