Draft, paraphrase, polish and grammar-check your assignments
Writing tools split into three jobs: getting words on the page, making bad sentences better, and catching the stupid mistakes you make at 2am. These seven cover all three, and knowing which job you actually need is most of the battle.
My rule is simple. Use grammar checkers on everything you write. Use paraphrasing tools on sentences you already wrote yourself. Be very careful with anything that generates the whole essay. Grammarly's free tier catches more than most students expect, but ignore its rewrites when they flatten your voice - graders notice the moment a sentence stops sounding like you. QuillBot is genuinely useful when you have read a source and need to restate it in your own structure, and unreliable when you are trying to dodge a plagiarism checker, which it does not reliably do.
Two things I wish someone had told me in first year. The tool does not improve the argument: if your thesis is weak, a polished version of a weak thesis is still weak, and it is far harder to fix once it is written. And check your course policy before leaning on any of these, because most departments now require you to disclose AI assistance. Declaring it costs you a line in the references; hiding it can cost you the module. When the assignment needs sources rather than sentences, that is what the research tools here are for.
I installed the browser extension freshman week and forgot about it until I wrote my first essay without it. It catches typos, passive voice, and tone issues everywhere - docs, emails, even messages to professors. I only paid for Premium during thesis season, and the student discount makes it like 40% cheaper. Worth every cent for that one month.
My go-to for the classic problem: I know what I want to say but it comes out clunky. Paste it in, get a cleaner version. Also a lifesaver for condensing long readings into something I can actually skim before class. Fair warning - it rewrites but doesn't explain, so use it on your own draft, not to pretend you read the chapter.
The way I actually use ChatGPT for essays: not to write them, but to argue with it. I ask for thesis options, outline structures, counterarguments to my own points - then I write the paper myself. Most schools now ask you to disclose AI use, so check your syllabus first. Treat it as the friend who brainstorms with you, not the one who writes your essay.
LanguageTool is what I recommend to every ESL friend who finds Grammarly's suggestions confusing. It supports 30+ languages, so my roommate checks her Spanish essays and I check my English papers in the same tool. The free version catches spelling, basic grammar and punctuation. It nags less than Grammarly, which I mean as a compliment.
Paste your essay into Hemingway and watch it light up like a crime scene - yellow for rambling sentences, red for impossible ones, purple for filler words. My professor said my writing 'improved dramatically' the semester I ran every draft through it. It doesn't check grammar; it checks whether a tired reader can survive your prose.
ProWritingAid is Grammarly for people who want a lecture, not a correction. Its 20+ reports told me my essay was 40% adverbs and that I started six paragraphs with 'However.' The free version only checks 500 words at a time, so I edit section by section - annoying, but it forces me to actually read the feedback.
I finished a 15-source bibliography in ten minutes with Scribbr - paste a URL or DOI, pick your style, copy the citation. No account, no paywall, no 'upgrade to export.' It was the difference between me sleeping before a deadline and manually formatting MLA hanging indents at 4am. My entire friend group switched after I showed them.
