What is your most used AI prompt or workflow that saves you real time

[Aisha]

Not looking for the obvious ones. Genuinely curious what specific prompts or AI workflows people have built that actually save meaningful time in their real lives. Whether work or personal. The kind of thing you use weekly or daily that you would miss if it was gone

[EventHorizon25]

Creating practice questions from documentation or notes I am trying to learn. I paste the material and ask for 10 quiz questions. Active recall beats passive re-reading

Rubber duck debugging with context. Pasting a function and the error message and asking what is wrong before I dig in myself. Catches obvious things I was too close to see

[NovaPrime68]

Pasting a long email thread and asking for a one-paragraph summary plus the specific decision that is being asked of me. Cuts meeting prep time dramatically

[ForumPhantom38]

A standing prompt for turning bullet point notes into professional emails. I write fast messy notes after calls and the AI formats them into a clear follow-up in seconds

Weekly meal plan from whatever is in my fridge. List the ingredients, say how many people, get a plan with a shopping list for the gaps. Actually use it every week
