AI Writing & Study Assistant
How to Summarize a PDF with AI on Mac
Forty-page reports, lecture slide decks, contracts, research papers — you don’t need to read all of it to know what matters. Attach the PDF in AI Writing & Study Assistant, pick a model, and ask. Summaries, key points, specific answers — in seconds, in a native Mac app.
More than a one-shot summary
- TL;DR first — “summarize this in 5 bullets” gives you the shape of the document instantly.
- Then interrogate it — “what does it say about termination clauses?”, “what method did they use in section 3?”, “list every deadline mentioned.”
- Structured output — ask for tables, pros/cons, or step lists instead of walls of text.
- Pick the right brain — Claude for long careful reads, Gemini for mixed text-and-image documents, DeepSeek for technical papers.
Summarize a PDF in four steps
- Download the app — Get AI Writing & Study Assistant free from the Mac App Store and open it — no account, no API keys.
- Attach your PDF — Click the attachment button (or drag the file in) — documents and photos work too.
- Ask for the summary you need — “Five bullets”, “one paragraph for my boss”, “explain it like I’m new to the topic” — the phrasing controls the output.
- Dig deeper — Follow up with specific questions; the model answers from the document you attached.
Where this beats PDF-suite AI tools
PDF editors with AI bolt a summarizer onto a paid PDF suite. Here the summarizer is a full AI chat: you choose the model, you can bring in web search for context, and the same window handles your follow-up writing — email the summary, turn it into slides, or make flashcards from it.
Common questions
What file types can I attach?
PDFs, documents and images. Attach a file and ask anything about its contents.
How long a PDF can it handle?
Long documents work — attach the file and ask section-specific questions for best results on very large PDFs.
Is my document uploaded somewhere?
Files are sent to the selected AI provider to generate the answer — same as any hosted AI tool. Chat history itself stays on your Mac with iCloud sync.
