01Section
The easiest win in AI for work
Somewhere in your inbox right now is a thread — twenty replies deep — that you need to understand before your next meeting. Or a page of notes you took last week that made sense at the time. Reading it all properly would take twenty minutes you don't have.
This is the ideal first work task to hand an AI tool, for one simple reason: you supply the material, and you can judge the result at a glance. If the summary is wrong, the original is right there. Nothing has to be taken on faith.
A useful analogy
It's like a colleague who reads the whole thread so you don't have to, then briefs you in the hallway. You'd still glance at the original before acting on anything important — but the briefing tells you exactly where to look.
Why this is safe ground
You have the source. A bad summary is obvious in seconds, and it costs you nothing but a retry.

Don't say "summarize" — say what matters
Type "summarize this" and you'll get a shorter version of everything — the important and the trivial flattened together. The one deadline you needed might end up buried in paragraph three.
The fix is naming what you actually need to know. In work threads and notes, it's almost always some mix of these:
- Decisions: What was decided or agreed — the things that are now settled
- Asks: Who is asking for what, from whom
- Deadlines: Dates and times — especially any that moved
- Who-needs-what: Anything waiting on you, or anything you're waiting on
- Open questions: What was raised but never resolved

Three formats that work
Beyond what to include, tell the AI what shape you want. Three formats cover almost every work situation:
TL;DR
Two or three sentences with the bottom line. For when you need the gist before a call starts.
Bullet-by-topic
A few bullets grouped under each theme. For long threads that wander across several subjects.
Action list
Only the tasks: who, what, by when. For threads that exist so that people will do things.
Vague ask
Summarize this email thread.
Specific ask
Summarize this email thread. Give me a two-sentence TL;DR, then any decisions made, then an action list of who needs to do what and by when. Flag anything that's waiting on me.
Same thread, same tool — the second version tells the AI which details count as important.
Key takeaway
A summary format is a decision about what matters. Pick the format before you paste.

04Section
Clean it before you paste it
Work threads carry more than information — they carry names, client details, and numbers that aren't yours to share. A thirty-second cleanup pass before pasting keeps the summary just as useful:
Swap names for roles: "Our PM" and "the client" summarize exactly as well as real names.
Cut confidential numbers: If the summary doesn't need the contract value, neither does the AI.
Drop signatures and footers: Phone numbers, addresses, legal boilerplate — noise anyway.
Privacy note: Work email belongs to more people than you. Strip names, client details, and anything confidential before pasting — and if your employer has rules about what can go into AI tools, those rules win.

Your reusable summary prompt
Put it all together and you get one prompt worth keeping — save it in your notes app and it's ready every time a long thread lands:
The keeper
Summarize the text below for a busy professional. Give me: (1) a two-sentence TL;DR, (2) decisions that were made, (3) requests and asks — who wants what, (4) deadlines and dates, (5) anything that appears to be waiting on me, (6) open questions. If a section has nothing, say "none." Don't add information that isn't in the text. [PASTE THE THREAD OR NOTES HERE]
One habit to attach
Before acting on anything in the summary — a date, a commitment, an ask — glance at the original. It takes twenty seconds and it's what makes this whole workflow trustworthy.

Prompt exercise
Summarize something real
Find a real long email thread or a page of messy notes from your week. Clean it first — roles instead of names, confidential details out. Then copy this prompt into ChatGPT, Claude, Gemini, Copilot, or whichever AI tool you have access to, and paste your cleaned text where marked. The website doesn't run AI itself — this exercise happens in your own tool.

Reflection: Compare the summary against the original. Did it catch every deadline and ask? Did it flag something waiting on you that you'd forgotten? That comparison is the habit that makes summaries reliable.
