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
NotebookLM
- The model answers only from uploaded sources: if the notebook holds an old version of a law, the answer follows the old version and still sounds confident
- Keep documents with personal data and trade secrets out of notebooks in a personal account: use NotebookLM as part of Workspace for them
