Description
Claude, built by Anthropic, is among the most capable assistants for demanding tasks: long-form writing, reasoning, code. The company is not an advertising giant and has no service ecosystem to cross-reference with your conversations. But it is American, hence subject to the Cloud Act, and since September 2025 conversations feed training by default (you can turn it off), with retention of up to five years. The right use: its power for work, nothing private.
My take
My tool for demanding tasks: the best I've found for programming and reasoning. In exchange, I share nothing private with it. That trade-off, I detail in chapter 13.
