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
LanguageTool
- The extension sends text to the service's servers for checking: for documents with trade secrets check your company policy or use a corporate plan with processing in Europe
- Accounting and legal terminology is often flagged as an error: add the terms to your personal dictionary instead of accepting every correction
