This is not everyone, but if you've been writing scientific papers with LaTeX, you may have come across this issue.
You go to an online database (Inspire or ADS) to fetch some references for your paper. Then you have to copy/paste the entry twice, the key to your LaTeX document and the BibTeX entry to your .bib file. Doing redundant things is annoying, right? autobib removes the need to do the latter. You still have to look up the key online and cite it in your LaTeX document, but autobib downloads the entry automatically to your .bib file.
