Summarise anything

AI can turn a 40-page report into one page in seconds, if you tell it what you need the summary for.

01 · The idea

Most assistants accept long text, PDFs, web pages, even video transcripts. Summaries are one of the most reliable things AI does.

A plain "summarise this" gives a generic result. Say who it is for and why: "Summarise for a busy manager who must decide whether to renew this contract." The AI then keeps what matters for that decision.

Ask for a structure: three key points, risks, numbers, and open questions. That makes summaries easy to scan and compare.

Summaries can still miss or twist details. For decisions, ask it to quote the exact sentence it relied on, so you can check quickly.
