How to use the summarizer
- Add a document or a table to “Your files”: PDF, Word (.docx), Markdown, text, HTML, CSV, TSV or JSON, up to 20 MB.
- Type “summarize it”, or open the Summarizer and choose how many key points you want (1–12) and, if you like, words to focus on.
- Read the key points with their page or section, the key terms and the outline; for a table, the totals, ranges, most common values and blanks.
- Download the summary as Markdown, have it read aloud, or put it in a report with your tables.

Extractive, so nothing is invented
The summary is made of the document’s own sentences. Each one is scored by how much of the document’s vocabulary it carries: a word counts for more the more often it occurs and the fewer sentences it appears in. The opening of the document and of each section gets a lift, so does any sentence with the words you asked to focus on, and fragments and run-on sentences count for less. The best sentences are taken, any that repeat one already taken are skipped, and they are shown in the order they appear.
Because nothing is reworded, nothing can be made up: every key point can be found in the file at the page or section shown beside it. The trade is that the sentences are the author’s, not a fresh paragraph written for you. For that, ask the document a question with Ask your documents, which uses a language model on your graphics card.
A table is summarized by arithmetic
A CSV, TSV or JSON list of records is read column by column. Each number column gets its total, average and range (prices and rates get no total, which would mean nothing), each label column its number of values and the most common one, and every column its blanks. When there is an amount such as revenue and a category such as region, the summary says which group holds the most of it and which the least.
- PDFs are read with pdf.js, page by page, in a background worker; scanned pages without text cannot be read.
- Word files are unzipped by the browser itself; HTML is reduced to its text.
- The summary is saved as Markdown in Results, ready for the report builder or the voice tool.
Questions
Summarizer: common questions
Is my document uploaded?
No. The file is read and summarized inside this browser tab, PDFs included, and the summary is saved only in the Files panel of this browser.
Why are the key points sentences from the document?
This summarizer is extractive: it picks the sentences that carry the most of the document rather than writing new ones. That makes every point checkable against its page, and it means the summary cannot contain anything the document does not say.
Can it summarize a spreadsheet?
Yes, as a CSV, TSV or a JSON list of records. It states the size of the table, the totals, averages and ranges of its number columns, the most common values of its label columns, any blanks, and which group holds the most of the main amount.
How long can the document be?
Up to 20 MB. A long document still gets the number of key points you asked for, up to twelve, taken from across the whole text.
