Working through a literature review means triaging far more sources than you can read closely. This tool takes a long text and returns its most important sentences exactly as written, so you can judge quickly whether a paper deserves proper attention.
It selects; it does not rewrite. Every sentence it returns appears verbatim in your source, which means it cannot attribute a claim to an author who never made it — the failure that makes generated summaries unsafe to work from.
A Master's literature review might draw on fifty sources, of which perhaps fifteen are read in full. The rest need a fast, honest judgement: is this about what I think it is about, and does it say something my review needs?
Running an abstract or introduction through here answers that in seconds, and the frequent-terms list shows what vocabulary the paper actually works in. Two papers with similar titles often turn out to use entirely different framings, and this surfaces that quickly.
The tool counts how often each meaningful word appears across the whole text, ignoring common function words. Each sentence then scores by how many high-frequency terms it carries, divided by its own length so that long sentences do not win on bulk alone.
The selected sentences are returned in the order they appeared, not in score order. Reordering by score would produce a passage that jumps between topics and reads as gibberish, even though every sentence in it is genuine.
It has no understanding of importance. A crucial finding stated once in plain language may score low precisely because it avoids the paper's repeated jargon, while a heavily repeated methodological aside scores high.
It also performs poorly on text without repeated vocabulary, on very short passages, and on anything conversational. Treat the output as a pointer to where the substance is, not as a replacement for reading the parts that matter.
The sentences returned here are the author's exact words. If any of them go into your thesis they need quotation marks and a citation, exactly as any other direct quotation would.
For a literature review you want paraphrase, not extraction. Read the summary, close it, and write the point in your own words — then cite the source. That produces genuine paraphrase rather than lightly edited copying, and it is also the only version of the process that leaves you understanding the material.
No. It selects the highest-scoring sentences and returns them word for word, so nothing is invented or altered.
For triage, yes — deciding quickly which of many sources deserve a full read. It does not replace reading the ones that matter.
Yes, and because the sentences are verbatim they need quotation marks too if used directly. Better to paraphrase from memory and cite.
It is assembled from sentences taken from different parts of the text. That is the cost of never inventing connecting prose.
Yes. Everything runs in your browser, so it works on a weak connection or none at all once loaded.
