A polished email can still fail if it hides the deadline or reply you need. Open Introduce and Chrome extension. Send Claude and Copilot the same brief: audience, facts, requested action, tone, and word limit.
- Facts stay unchanged
- Action is easy to find
- Tone fits the relationship
Read both answers beside source notes. Mark invented details, softened deadlines, missing owners, and vague asks. Do not choose by confidence. In Introduce and Chrome extension, ask: “Keep every fact and place the requested action in the final two sentences.”
Save the prompt, missing condition, and final edit. This keeps the next comparison consistent without claiming one model is always better. By Meka Coven. Return to Introduce or Chrome extension, verify each date, name, and commitment, then send.
