Students use this set for the mechanics of an assignment, not the writing itself: stitch scanned pages into one file with PDF Stitcher, format a source into APA, MLA or Chicago style with Citation Generator, and condense a long PDF reading down to its key sentences with Text Summarizer before an exam.
Every file is processed on your own laptop or phone — a draft essay or research notes are never routed through a third-party server, and there's no account to make or ad to sit through before the download. Free for as many assignments as the semester throws at you.
