Find the code behind a paper without hunting through footnotes.
What this tool does
This tool extracts code repository links from pasted text. It scans for URLs on GitHub, GitLab, Bitbucket, and SourceForge, removes duplicates, and lists each unique repository link as a clickable address. Papers increasingly point to code, but the link often hides in a footnote, a data statement, or a README, and gathering the links into one list saves a hunt through the whole document.
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 a paper section, a README, or your own notes, and press the find button. Click each listed link to check that it opens the repository you expected, and note whether the repository is public, archived, or empty, because a link alone does not guarantee usable code.
Worked example
A passage mentioning code at github.com/example/sleep-study and a pipeline at gitlab.com/example/pipeline yields a two-link list with both addresses clickable. The reader can open the code and the pipeline directly, instead of re-reading the passage to copy each address by hand.
How to read the results
The output is a deduplicated list of repository links with a count, each link clickable and opening in a new tab. Links to other sites are ignored, deliberately, so the list holds only code repositories and not every URL in the paste. If a link appears twice in the paste, it appears once in the list, because duplicates are removed before display.
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 finds links, it does not verify them: a repository can be deleted, made private, or emptied after publication, and the tool will still list its address. It also only recognises the four named hosts and standard owner-and-project URL shapes, so shortened links, DOIs pointing at code, and repository links broken across lines will be missed. Always click through before citing code availability.
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.
