# How to Summarize a Document

How to summarize a document with Chat Octopus: upload a PDF, Word file, or plain text and get bullet points, an executive brief, or just the action items.

A long document rarely needs a full read before you know what matters in it. Describe the summary you want, and Chat Octopus pulls it out of the file for you.

## Upload the document and ask

Start a new chat, attach the file, and say what you want in the same message. A PDF, a Word file, or plain text all work the same way: [drop it in and ask](/docs/getting-started).

- "Summarize this report in five bullet points."
- "What are the decisions and action items in these meeting notes?"
- "Give me an executive summary of this proposal."

You get the substance without reading every page to find it.

## Choose the kind of summary you need

There is no single "summary" setting. You describe the shape you want, and the length comes with it:

- **A quick overview**: "sum this up in one paragraph."
- **Skimmable points**: "five bullets, most important first."
- **Just the actions**: "pull out every decision and who owns it."
- **Section by section**: "one sentence per section, in order."
- **One thread only**: "everything the document says about budget."

Ask for a different format later and you get it, from the same file, without starting over.

## It reads the structure, not just the words

A copy-paste summarizer treats every sentence the same. Chat Octopus reads the document the way a person would: a heading frames what follows, a recommendation carries more weight than background, and an action item buried on page thirty-seven counts as much as one on page two. So the summary keeps the parts that decide things and drops the padding.

## Ask follow-ups without re-uploading

The summary is the start of a conversation, not the end of one. The whole document stays loaded and [the conversation keeps its context](/docs/using-chat), so you can keep going in the same thread: "expand the second point," "what does it say about pricing," "now give me the one-line version for an email." You are still working from the original file, so nothing gets lost along the way.

## What you can hand it

Most document formats work: PDF, Word (DOCX or DOC), and plain or rich text. A forty-page report is no harder than a two-page memo. It's read in stretches of about two thousand lines, and a file longer than that gets covered in several more passes instead of one straight read-through, which evens out the weighting, so ask for a line per section first and then for depth on the sections that deserve it.

Some files want a different question, though. A workbook with formulas across several tabs is a job for [asking the spreadsheet itself](/tools/excel-chat), and a flat export from your bank or a tool wants [totals and groupings rather than prose](/tools/csv-analyzer). When you already know the exact clause you are after, skip the summary and [ask the PDF for the wording and the page](/tools/pdf-chat). And if the pages arrived as a scan or a photograph, the words are pictures rather than text, which is [a slightly different ask](/guides/extract-text-from-an-image).

So the next time something long lands in your inbox, you do not have to read all of it to know what it says. [Open the document summarizer](/tools/document-summarizer), add your file, and ask for the version you actually need. Every follow-up works from the same upload, so you never attach it twice.
