Frequently Asked Questions

How does the summary work?
The document's text is analysed to identify the most significant passages, which are drawn together into a shorter overview. It gives you the substance of a long document quickly, which is usually enough to decide whether the full text is worth your time.
Can it summarise a scanned PDF?
Not directly — a scan has no text to analyse, only images of pages. Run it through Extract Text (OCR) first to produce a text layer, then summarise the result.
How accurate is the summary?
It reliably identifies what a document is about and what its main points are. It is not a substitute for reading anything you intend to rely on, and should never replace reading a contract, a legal document, or anything with consequences attached.
What length of document works best?
Documents with a clear structure and sustained argument — reports, articles, papers, and proposals — summarise well. Very short documents have little to condense, and highly fragmented content such as tables of figures does not summarise meaningfully.
Does it work with any language?
Results are strongest for English. For documents in other languages, consider Translate PDF first, then summarise the translated text.
Are my documents stored on your server?
No. Your file is processed in memory and discarded once the summary is produced. Nothing is written to disk, nothing is logged, and no copy is retained.

The Problem With Long Documents

Most documents that land on you are not ones you chose. A supplier sends a sixty-page specification, a committee circulates a report, a colleague forwards a paper "worth a look". Each represents an hour you had not planned for, and often the useful conclusion is that it was not relevant to you at all.

The genuinely wasteful part is not reading things carefully — it is reading things carefully to discover they did not need reading. A summary answers that question in seconds rather than an hour, and lets you spend your attention on the documents that actually deserve it.

What a Summary Is Good For

Triage. The primary use. Is this relevant? Does it affect my work? Do I need to read it properly? A summary answers all three quickly.

Recall. Coming back to a document you read months ago, a summary reminds you what it contained faster than skimming it again.

Briefing. Explaining to a colleague what a document says without either of you reading the whole thing.

Screening a set. Faced with twenty candidate papers or reports, summarising each identifies the three that matter before you commit real time to any of them.

What a Summary Is Not Good For

This deserves stating plainly. Never rely on a summary for anything with consequences attached.

Contracts, legal documents, medical information, regulatory requirements, financial commitments, and safety instructions all need reading in full. The significant content in those documents frequently sits in exactly the places a summary compresses — a conditional clause, a specific figure, an exception that applies only in certain circumstances.

A summary tells you what a document is broadly about. It does not tell you what you are agreeing to. Use it to decide what to read, not as a replacement for reading.

What Summarises Well

Reports, articles, and research papers summarise well because they have a clear structure and a sustained argument with identifiable main points.

Proposals and business documents summarise well for the same reason.

Meeting minutes and correspondence summarise reasonably, though action items are worth checking directly.

Tables, figures, and reference material do not summarise meaningfully — there is no argument to condense, just data that either matters to you or does not.

Contracts and legal text can be summarised for orientation but must never be relied upon in that form.

Who Uses This Tool

Researchers and students screening papers to decide which to read properly. Managers processing reports and proposals arriving faster than they can be read. Consultants getting up to speed on unfamiliar material at the start of an engagement. Journalists assessing whether a lengthy release or filing contains anything of interest. Anyone facing a backlog of documents they are expected to have read.

How to Summarize a PDF

Upload your PDF by dragging it onto the box or clicking to browse. The text is analysed and a summary is produced. Read it, decide whether the full document is worth your time, and read properly if the answer is yes.

Scanned Documents Need OCR First

If your PDF came from a scanner, it contains images rather than text and there is nothing to analyse. Extract Text (OCR) recognises the characters and produces a text layer, after which summarisation works normally.

Documents in Other Languages

Summarisation works best on English text. For documents in other languages, running them through Translate PDF first and then summarising the translation generally produces better results than summarising the original directly.

Your Privacy Is Protected

Your document is processed in memory and discarded once the summary is produced. Nothing is written to disk, nothing is logged, and no copy is retained.
