Pitfalls to watch at work

Claude

• On the free and personal paid plans, check Settings, Privacy: training on chats should be off before a work document goes in
• Contracts and correspondence go in only with parties, amounts and details anonymized: [Buyer], [Supplier], [amount]
• The limit is measured by conversation size rather than message count: a long chat with a large file uses up the quota in a few questions, so open a separate chat for each document

Copilot in Word

• Compare two versions of a contract with Word's built-in Compare and ask Copilot to explain the changes found: on its own it misses some edits
• Rewriting in a different tone also changes the content: after Rewrite, check amounts, dates and party names against the original
• In the business version Copilot may pull a passage from someone else's document you have access to: check the sources in the answer
