Pitfalls to watch at work

ChatGPT

• On the free and personal paid plans, chats may be used for training by default: in Settings, Data controls, turn off Improve the model for everyone before your first work task
• Employee names and tax IDs, account details, amounts and contract terms go into the chat only anonymized: replace them with [Employee 1], [Counterparty], [X]
• The model invents statute numbers, court decisions and links in a confident tone: check every such fact in the primary source

Gemini in Google Docs

• Ask the model to take numbers only from the block you give and to write [CAUSE, confirm] where it wants to fill gaps: otherwise the explanation gets invented causes for variances
• The panel can pull any Drive file by link: make sure data from unrelated matters does not end up in the document
• After inserting a draft, check every figure against the source: the model rounds and flips signs without warning
