Long documents have a habit of burying the actual point somewhere around page 11. By the time you get there, you’ve already lost 40 minutes and half your will to live. This prompt fixes that.
TL;DR: One 24-word prompt compresses any dense document into 5 bullets and 2 key takeaways. No setup, no plugins, no summarizer tool.
The Prompt
Here it is, exactly as shared on r/PromptEngineering:
“Give me the ‘TL;DR’ version. Max 5 bullet points. Why does this matter? Tell me the 2 biggest takeaways.”
Paste it before any document. Works in Claude, ChatGPT, Gemini. Nothing to configure.
The mechanics are simple: copy the prompt, paste it at the top of your message, then paste the full document text underneath. Or if you’re working with a URL or uploaded file, paste the prompt first and let the model handle the rest. Either way, you get a structured briefing in seconds. The whole thing takes less time than scrolling to find the executive summary that may or may not exist.
Worth keeping this somewhere fast to access. A notes app, a pinned message, a text expander shortcut. The faster you can reach it, the more often you’ll actually use it.
Why It Works
Most AI summaries default to long, structured recaps because nothing told them not to. Without constraints, a model will mirror the length and structure of the source material. You give it a 20-page report, it gives you a 4-page summary. Marginally faster, still exhausting. This prompt pushes back against that.
Three things are happening at once: “Max 5 bullets” forces real compression, so the AI can’t pad with length. “Why does this matter?” adds an editorial layer on top of the summary, not just a restatement. And “2 biggest takeaways” puts a hard ceiling on noise.
That combination turns a passive recap into a prioritized briefing.
The editorial question is the underrated part. Asking “why does this matter?” forces the model to reason about relevance, not just extract sentences. It’s the difference between a highlight reel and a clip someone actually cut for you. A standard summary tells you what the document said. This prompt tells you what to do with it.
The hard ceiling on takeaways also matters more than it looks. Two forces you to rank. If you ask for five takeaways, the model fills five slots. Ask for two and it has to decide what actually counts. That decision is where most of the value lives.
📋 Use Cases
- Legal contracts you need the gist of before a call. You’re not replacing your lawyer, you’re walking into the conversation knowing which clauses to ask about.
- Research papers where you want conclusions, not methodology. Skip straight to what the study found and whether it’s relevant to what you’re working on.
- Internal reports with 18 slides before they get to the point. Every company produces these. Now you don’t have to suffer through them to participate in the meeting.
- News articles flagged but never read. That backlog of saved tabs you keep meaning to get to? Run them through this prompt in batches.
- Vendor proposals that bury pricing in the appendix. Get the structure of the offer in 30 seconds before you decide if it’s worth reading the full thing.
The common thread across all of these: you’re not skipping the information, you’re front-loading the decision about whether it deserves more of your time. Sometimes the summary is enough. Sometimes it tells you exactly which section to read carefully. Both outcomes are wins.
Prompt of the Day
“Give me the ‘TL;DR’ version. Max 5 bullet points. Why does this matter? Tell me the 2 biggest takeaways.”
Copy it once. Keep it somewhere you can grab it fast. The next 20-page PDF that lands in your inbox will thank you.
If you want to push it further, you can append one line depending on context: “Focus on implications for [your role or goal].” That extra constraint personalizes the output without complicating the core prompt. A founder gets different takeaways from a market research report than a product manager does. Give the model that context and it sharpens the output considerably.
Bottom Line
The best prompts don’t optimize for completeness. They optimize for your time. This one does exactly that in 24 words.
Most people treat AI summarization as a nice-to-have. Something you do when you’re feeling lazy. Flip that. Summarize first, read in full only if the summary tells you it’s worth it. That’s the workflow change. The prompt is just the tool that makes it fast enough to actually stick.
Save it. Use it. You’ll stop reading full documents the long way.
