Is it safe to summarize work email with AI?
With the included Mail2Action AI, the thread text is processed only to create your result and is never stored or logged; it is not used for training. If your company prefers its own AI account, add your own API key for OpenAI, Google Gemini, Anthropic Claude, or xAI Grok — the text then goes directly from your browser to that provider.
