Where AI Pays You Back First
The best AI use cases aren't the flashy ones - they're the boring tasks you do a hundred times a week. Small wins, repeated daily, beat one impressive demo every time.
Email: The 10-Second First Draft
- Draft replies: paste the email you got, ask for a professional reply in your tone
- Fix tone: "Rewrite this more politely" / "more direct" / "less passive-aggressive" (that last one saves marriages)
- Summarise the inbox: paste the long thread, get the decision that's actually needed
- Never write from zero: you're the editor, AI is the first drafter
Documents: From Blank Page to Nearly Done
- Outlines first: "Give me an outline for [document type]" before writing a single word
- Rewrite and compress: "Cut this to half the length without losing meaning"
- Turn notes into prose: paste your messy bullet points, get a clean paragraph
- Create templates: ask for a reusable template for anything you do repeatedly - meeting notes, reports, proposals
- Format on command: "Turn this into a table" is one of the most underrated prompts in existence
Research: Faster, With Receipts
- Ask for sources: "Summarise this topic and list where I can verify each point"
- Use a search-connected tool (Perplexity, or ChatGPT with web search) so answers come with links
- Two-model check: ask two different AIs the same question; agreement is reassuring, disagreement is interesting
- Never cite AI: cite the sources it found, after you check they exist
The Personal Assistant Stuff (Yes, This Counts)
- Meal planning: "Plan 5 dinners from what's in my fridge"
- Travel: "Build a 3-day itinerary in [city] that's walkable and cheap"
- Learning: "Explain [topic] as if I'm twelve, then quiz me"
- Household: "What's the fastest way to remove [stain]" - it's a legitimate use of a trillion-parameter model, and it works
The 20-Minute Daily Habit
- Morning (5 min): ask AI to plan your day or prep for your hardest meeting
- Midday (10 min): use it for one task you'd normally dread
- Evening (5 min): ask it to summarise what you learned today, or draft tomorrow's first step
Within a week, the habit replaces itself - you'll reach for AI automatically on the tasks where it helps.
