Linnk Research Paper Summarizer is an AI tool built specifically for academic literature. It reads the whole paper — abstract, methods, results, discussion, and conclusion — and returns a summary structured the way researchers actually read papers: main claim, evidence, limitations, contribution to the field. Output as a paragraph, outline, bulleted brief, or interactive mindmap. Cross-language input means a Japanese paper produces an English mindmap in one step — no translation step needed. Free every month — a monthly allowance lets researchers and analysts summarize papers 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 researchers and analysts at Stanford, Anthropic, McKinsey, and the University of Tokyo.
Pick the shape that fits the audience
Interactive mindmap
A clickable mindmap of the whole document — collapse and expand branches, jump to source pages. The format Linnk's competitors don't ship.
Built for the way researchers and analysts read
research-paper-features-desc
Whole-paper, structured the way researchers think
Abstracts, methods, results, discussion, and conclusions get separate treatment in the outline view. The summary mirrors how researchers actually evaluate a paper.
Cross-language input by default
A Japanese paper in, an English mindmap out — single shot, no translate-then-summarize round-trip.
Equations and citation context preserved
Display equations are read in math notation; citation context ("Smith 2023") stays attached to the claim it supports.
Mindmap output for lit reviews
Convert each paper into a clickable mindmap; combine 20 paper mindmaps into a comparable view for your lit review.
Cited and verifiable
Every claim links back to the page and paragraph in the source paper — verify before you cite.
Free every month, plus the browser extension
A monthly free allowance lets you summarize papers without paying, and the same allowance covers web pages (preprints, blog posts) through the Linnk browser extension.
Frequently asked questions
Can it summarize a paper into a language different from its source?
Yes. Input and output languages are independent — drop in a paper in any of 150+ supported languages and pick the output language separately.
Are equations and figures handled correctly?
Yes. Display equations are read in math notation; figures and their captions are summarized together; citation numbering is preserved.
Can I cite the summary in my own work?
The summary is faithful and high-quality, but for any quotation or formal citation we recommend referencing the original-language paper as the canonical source. For internal lit reviews and working notes, the summary is robust enough to use directly.
Does it handle scanned or image-only papers?
Yes. AI vision reads each page directly before summarization — no OCR step. Old archives, scanned reprints, and photographed pages all work.
Can I ask follow-up questions about the paper?
Yes. Every paper opens in a chat-enabled view: ask in any of 150+ languages and get answers grounded in the paper itself, with page-level citations.
Is my paper kept confidential?
Papers are encrypted in transit and at rest, are not used to train models, and are automatically deleted within 48 hours.
How much does Linnk Research Paper Summarizer cost?
Linnk includes a free monthly allowance so researchers and analysts can summarize papers 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.
