Gmail has an AI assistant built in now, but reaching it is its own little chore. You move the mouse to the corner, find the right icon, click, and wait for the side panel to slide open before you can ask anything. For something you might do a dozen times a day, that is a lot of clicking.
CMDK gives Gmail’s AI a keyboard shortcut. Press one key on the email you are reading and the assistant opens, ready for your question.
What “Ask AI” does
Ask AI is a fast path to Gmail’s own Gemini side panel. While you are reading a thread, one keystroke opens the assistant in context, so you can summarize a long thread, draft a reply, pull out action items, or ask anything about what is in front of you, without leaving the email or reaching for the mouse.
It is the same Gmail AI you already have. CMDK just removes the friction of getting to it.
How to use it
Open the email you want help with, then press:
ito open the AI assistant for that email.
The Gemini panel opens and you can start typing your question right away. You can also trigger it from the command bar: press Cmd + K (Mac) or Ctrl + K (Windows) and run Ask AI.
Why a shortcut matters here
AI is only useful in email if it is faster than doing the thing yourself. The moment “ask the assistant” means traveling to a corner of the screen and clicking, half the speed is gone and you stop bothering. A single key keeps it instant, so reaching for AI becomes a reflex instead of a detour, exactly when you are staring at a thread you would rather not read end to end.
Where it helps
- Long threads you want summarized before you reply.
- Dense updates where you just need the decisions and action items.
- Drafting a first pass at a reply you can then edit.
- Quick questions about what an email is actually asking for.
