Collect every passage you marked into a single list you can export.
What this tool does
This tool gathers highlighted passages into one list you can copy or download. You mark passages in your pasted text by wrapping them in double square brackets, and the tool extracts every marked passage in order into a numbered list. That list is the raw material of a reading summary: the sentences you thought mattered, collected without retyping and without the surrounding text you skipped.
It works fully in your browser. Nothing is uploaded to a server, and you do not need an account. Paste your text, press the button, and read the result on the same page. That makes it useful for students, researchers, and anyone who has to get through a long paper quickly without losing the important parts.
How to use it
Paste your text and wrap each passage worth keeping in double square brackets, like this: [[passage to keep]]. Press the gather button and read the numbered list, checking that each item is complete and in the order you marked it. Then copy the list or download it as a text file for your notes.
Worked example
A sentence saying sleep improves memory by 23 percent in rested students and strengthens neural connections during rest, with both the percentage phrase and the connections phrase wrapped in brackets, yields a two-item list: first the percentage phrase, then the connections phrase. The rest of the sentence is dropped, which is exactly the point: the list holds only what you chose to keep.
How to read the results
The output is a numbered list of highlights in marking order, with a count. If no brackets are found, the tool says so plainly and reminds you of the format, rather than returning an empty list that looks like a failure. Copy and download buttons export the list as plain text.
Do not treat the output as a final answer. It is a starting point for your own reading. Skim the highlighted parts first, then read the full passage around anything that matters for your work. A tool can point at the likely important sentences, but only you can judge whether they are actually important for your question.
Honest limits
Highlights are only as good as your marking: the tool cannot tell whether a marked passage is actually important, fairly quoted, or taken out of context. It also cannot read highlights from a PDF, an e-reader, or another app directly; you must paste text with brackets yourself. Always check a highlight against its original paragraph before quoting it, because a short excerpt can easily mislead.
This tool does not use artificial intelligence, and it does not understand your paper the way a human reader does. It follows fixed rules that you can inspect in the results. That is a strength when you want transparent, repeatable results, and a weakness when a passage needs real understanding, context, or judgement.
Tips for best results
Paste clean text. Remove page headers, footers, and reference lists before you paste, because they add noise to word counts and sentence scores. Work on one section at a time for long papers, and keep your original file open beside the tool so you can check anything surprising against the source. If you use the result in your own writing, always cite the original paper, never the tool output.
Frequently asked questions
Is it free? Yes. The tool is free to use online, with no sign-up and no download.
Is my text stored anywhere? No. Everything runs in your browser tab. Closing the tab removes your pasted text.
Can I trust the output completely? No tool of this kind should be trusted blindly. Use it to speed up reading and checking, then verify the important claims yourself in the original text.
