AI PDF Summarizer (PDF, Word, PowerPoint, EPUB)

About the AI PDF Summarizer (PDF, Word, PowerPoint, EPUB)

Open a PDF, a Word or PowerPoint file, an EPUB book, an e-mail or a text file — or a scan or photo of pages, read with on-device OCR — and get it summarised the way you need: key points, a TL;DR, section by section (from the PDF’s bookmarks or its headings), chapter by chapter for books, an executive summary, meeting minutes with decisions and action items, a court judgment digest, or a plain-language version. Pick short, medium or long, and write it in the document’s language or another one.

Every line shows the page it comes from — select it to read that passage — and any number, date or name in an AI line that the document doesn’t contain is highlighted, so you know what to check. A summary without AI appears at once, made of the document’s own key sentences; then the AI summary is written by your browser’s built-in AI or a model on your device, or, with a pass, by MySmartCoPilot’s cloud AI. Long documents are summarised part by part with a progress bar. Without a pass you get the free preview: the first half of the summary.

Common uses

• Getting the gist of a long report, policy or tender before deciding to read it in full.
• Revision notes from a textbook chapter, lecture slides or a research paper.
• Turning raw meeting notes into minutes with decisions and owners.
• A neutral digest of a court judgment to see what it held, before reading the judgment itself.

Summary types

• Key points and TL;DR: the most important points, or the gist in a few sentences.
• Section by section: a few points per part — by the PDF’s bookmarks, else its headings, else five pages at a time. Chapter by chapter does the same for an e-book’s chapters.
• Executive summary: an overview, the key points, and only the recommendations or next steps the document itself states.
• Meeting minutes: what was discussed, the decisions, and the action items as “who — what — by when”.
• Court judgment digest: the case, facts, issues, reasoning and decision as the judgment states them, in neutral words. It never says whether a decision is right and is not legal advice.
• Plain-language version: the document explained in everyday words.

How the summary stays true to the document

• Only the document. The AI is told to use only what the text says, to keep names, numbers and dates exactly, and to treat the document as data, never as instructions. Hidden text in the file (invisible, tiny or white text) is left out before anything is summarised.
• Highlighted checks. Numbers, amounts, dates and names in an AI line that the document doesn’t contain are highlighted.
• Source pages. Each line is matched to the passage of the document it is closest to, and that page is shown beside it.
• No AI, no invention. The summary without AI is made only of the document’s own sentences (TextRank), with keyword rules for decisions and action items.

Where the AI runs, and long documents

• Your browser’s built-in AI where it has one (some desktop browsers).
• A language model on your device, downloaded once from MySmartCoPilot after you agree: about 1 GB on computers (about 350 MB on phones) with WebGPU, or, on a computer without WebGPU, a slower build of about 630 MB that runs on the processor. Any length of document works here, part by part.
• MySmartCoPilot cloud, with a pass, after a dialog shows what is sent (the text with e-mail addresses, phone numbers and similar details masked). It summarises about the first 20 pages, and the summary then says which pages it covers.

A very long document is first cut to its key sentences, chosen without AI, so that it fits the AI’s limit; the summary says so.

Limitations

• One file at a time, up to 50 MB and 500 pages. Scans are read with on-device OCR, which can misread names and numbers, up to 40 pages per run.
• Tables, charts and pictures are read as text where they have text; numbers in a chart’s picture are not read.
• Small on-device models can miss nuance or merge points; check the highlighted words and the source pages before relying on a summary.
• A summary in another language than the document’s needs AI, and names may be spelt differently there.
• The PDF download writes Latin, Greek and Cyrillic text; for Hindi and other scripts that need letter shaping, download Word instead.
• The document and its summary stay only in this tab: reloading the page clears them.

Privacy

Your document is read on your device and never uploaded. The AI summary is written by your browser’s built-in AI where it has one, or by a language model downloaded once from MySmartCoPilot after you agree (the size is shown first). Only if you choose MySmartCoPilot cloud (with a pass) is the document’s text, with personal details masked, sent to MySmartCoPilot’s cloud AI; a dialog shows what is sent first.
