Stop losing your place every time a paper says "see Section 3".
What this tool does
This tool turns cross-references in pasted text into working links. You paste text with section headings such as Section 1 and references such as see Section 1, and the tool links each reference to its section heading and adds a back link at every heading, so you can jump to a referenced section and return to where you were. Long papers constantly say see Section 3, and this tool makes those words do what they promise.
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 with section headings on their own lines, written as Section followed by a number, and references written the same way inside paragraphs. Press the link button and click a reference to jump to its section, then use the back link at the heading to return. If a reference stays unlinked, its section heading is missing or spelled differently.
Worked example
A two-section paste where Section 2 says “As shown in Section 1, sleep matters” becomes a page where Section 1 in that sentence is a link to the Section 1 heading, which itself carries a back link to the top. The reader jumps, checks the background, and returns in two clicks, instead of scrolling and hunting for the right paragraph.
How to read the results
The output is your text with linked references and back links at headings, in reading order. References to sections that do not exist in the paste are left as plain text rather than linked to nowhere, so a missing link always means a missing or mismatched heading.
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
The tool recognises only the Section-number pattern, not chapter, figure, table, or appendix references, which have their own tool in this family. It also cannot handle references that use a section title instead of a number, or sections numbered with words rather than digits. For a full document, a word processor’s real cross-references remain the better format.
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.
