Drop in a long PDF — even a scanned one — ask anything, get a summary in any language as a paragraph, outline, bullets, or interactive mindmap. Linnk reads the whole document, not the first chunk; supports 150+ languages on input and output; and ships the mindmap output ChatPDF and NotebookLM don't.
Linnk AI PDF Summarizer is an AI-powered PDF reader and summarizer designed as a more capable alternative to ChatPDF and NotebookLM. It reads the whole PDF in one pass — even 200-page documents — supports cross-language input and output across 150+ languages, accepts scanned and image-only PDFs, and produces summaries as a paragraph, bullets, outline, or interactive mindmap. Every claim in the summary links back to the source page so you can verify before quoting. Free every month — a monthly allowance lets you summarize PDFs without paying, and the Linnk browser extension shares the same allowance for web pages. From there, one subscription unlocks unlimited use across every Linnk tool. Used daily by 300,000+ paid professionals at Apple, Google, Anthropic, McKinsey, and Stanford.

Linnk reads the whole PDF in one pass — even 200-page documents. ChatPDF-style page-by-page splitting misses the conclusion.
Old archives, scanned reports, photographed pages — Linnk's vision models read each page directly before summarization (no OCR step), then return the same shape of summary you'd get from a digital PDF.
Read in any of 150+ languages, summarize in any of 150+ languages — no separate translation step.
Convert the PDF into an interactive tree of claims and evidence. Click any node to jump to the source page.
Every claim in the summary is anchored to the page it came from. Verify before you quote.
A monthly free allowance lets you summarize PDFs without paying, and the same allowance covers web pages through the Linnk browser extension.
Three practical differences. Linnk reads the whole PDF in one pass (no page-by-page splitting), supports cross-language input and output (Japanese in, English out), and produces interactive mindmap output that ChatPDF and NotebookLM don't ship. It also handles scanned and image-only PDFs end-to-end.
Yes. Every PDF opens in a chat-enabled view: ask in any of 150+ languages and get answers grounded in the document itself, with page-level citations back to the source.
Yes — and most competitors don't. Linnk's vision models read each page directly — no OCR step — so scanned archives, photographed pages, and image-only PDFs all work.
Paid plans go up to 300 MB or 300 pages per file. The summary reflects the entire document including the conclusion.
Paragraph, bulleted brief, hierarchical outline, or interactive mindmap. The mindmap is unique among PDF summarizers.
PDFs are encrypted in transit and at rest, are not used to train models, and are automatically deleted within 48 hours.
ChatGPT requires manual upload, often loses the layout, and stops at its context window. Linnk is purpose-built for PDFs: handles the whole document, preserves citations to source pages, and produces structured output (mindmap / outline) that ChatGPT can't.
Linnk includes a free monthly allowance so you can summarize PDFs every month without paying — the same allowance covers web pages via the Linnk browser extension. One subscription beyond the allowance covers unlimited use plus every other Linnk tool.
