A user reported that Gmail's web interface generated unprompted message summaries and reply drafts via language models, displayed persistent prompts like "Press / for Help me write" and "Tab to improve," and highlighted a "help me write" button during composition. The primary account documented that some AI features lacked independent toggles without disabling thread categorization, interpreted this as deliberate metric inflation, and initiated migration to Fastmail with a custom domain while retaining contacts only. Google's Gemini integration announcements reference optional AI assistance in Gmail, while user reports on platforms like Reddit detail similar navigation interruptions from AI prompts in 2024; Fastmail documentation confirms domain alias support without generative AI overlays.
