Grammarly vs QuillBot for Students 2026
Students use these two tools for very different things. Grammarly catches grammar, spelling, and tone errors as you write — it works inside Google Docs, your browser, and every writing surface you use. QuillBot paraphrases, summarises, and rewrites existing text — it is the tool students reach for when incorporating research into essays or rewriting notes into their own words. Both have genuinely useful free tiers. The question is which one fits your specific student workflow — or whether you need both.
The AI Map Verdict — June 2026
For most students: use both free tiers simultaneously at $0 total.
If you can only pay for one: QuillBot Premium ($9.99/mo) beats Grammarly Pro ($12/mo) on student-specific value.
QuillBot's Academic paraphrase mode, citation generator, summariser, and plagiarism checker are purpose-built for student work. Grammarly Pro's best features — brand tone, style guides, team analytics — are irrelevant for students. Grammarly free is excellent for real-time grammar correction. Run both free tiers together and only upgrade QuillBot if you write at high volume.
Quick Answer — Last verified: June 2026
Use Grammarly free for real-time grammar and spelling correction while you write essays. Use QuillBot free (125 words/paraphrase) to rephrase research in your own words. Both free tiers cost $0 and cover most student needs. If you write long essays and need plagiarism checking, upgrade QuillBot Premium ($9.99/mo) before Grammarly Pro ($12/mo).
Decision Rules for Students
- Use Grammarly if you:
- Want real-time corrections while typing essays in Google Docs, Word, or your browser. Grammarly's free extension catches grammar, spelling, and punctuation errors as you write — no copy-paste needed.
- Use Grammarly if you:
- Struggle with tone in academic writing. Grammarly's tone detector flags overly casual language and suggests more formal alternatives — useful when your writing needs to sound professional or academic.
- Use QuillBot if you:
- Paraphrase research sources into your own words. QuillBot's Academic paraphrase mode rewrites text while preserving the original meaning — the core task for citing sources without copying them directly.
- Use QuillBot if you:
- Need to summarise long readings quickly. QuillBot's Summarizer condenses academic papers, chapters, and articles into key points — a genuine time-saver for heavy reading loads. Grammarly has no equivalent tool.
- Use QuillBot Premium if you:
- Write essays over 125 words (most students do). The free paraphrase limit of 125 words means you must work in chunks. Premium removes this limit entirely — $9.99/mo or cheaper annual. Cheaper than Grammarly Pro at $12/mo.
- Use both free tiers if:
- You write original essays and also incorporate research sources. Grammarly free catches errors as you type. QuillBot free handles paraphrasing in 125-word chunks. Total cost: $0. This is the setup most students should start with.

Student Use Case Verdicts
Writing and proofreading essays
→ Grammarly wins
Grammarly's free browser extension catches grammar, spelling, and punctuation errors in real time inside Google Docs and Word — the two places students actually write essays. It also detects tone mismatches (too casual, too aggressive) and suggests clearer phrasing. QuillBot is a paste-and-rewrite tool — you have to actively bring text to it. For the essay-writing workflow itself, Grammarly's always-on correction is more valuable.
Paraphrasing research sources and citations
→ QuillBot wins
QuillBot's paraphraser with Academic mode is designed specifically for this task. You paste in a sentence or paragraph from a source, select Academic mode, and get a properly reworded version to incorporate into your essay. The free tier (125 words per paraphrase, unlimited uses) covers most individual sentences and short passages — which is exactly how students cite research. Grammarly can rewrite text but has no Academic mode and is not built for paraphrasing source material.
Reading and summarising long academic papers
→ QuillBot wins
QuillBot's Summarizer condenses long documents into key points at adjustable lengths. Students can paste in a journal article or textbook chapter and get a structured summary in seconds. This is a genuine time-saver for heavy reading loads in university courses. Grammarly has no dedicated summariser — it can help with writing but not with processing information you need to read and understand.
Checking for plagiarism before submission
→ QuillBot wins (on price)
Both Grammarly Pro and QuillBot Premium include plagiarism checkers. QuillBot Premium costs $9.99/month vs Grammarly Pro at $12/month — so if plagiarism checking is your primary reason to pay, QuillBot is the cheaper option. QuillBot Premium includes 25,000 words/month of plagiarism checking. Grammarly's plagiarism checker is also solid. The deciding factor is simply price — and QuillBot is $2/month cheaper with more student-relevant tools in the rest of the package.
Non-native English speakers writing academic work
→ Use both
Both tools help significantly. Grammarly's free tier catches grammar errors as you write and flags unnatural phrasing in real time — essential for catching mistakes before they accumulate into a draft full of errors. QuillBot's Fluency mode rewrites awkward sentences to sound more natural in English. For non-native speakers, the combination of both free tiers is more powerful than either alone: Grammarly prevents errors while writing, QuillBot fixes awkward passages after drafting.
Avoiding AI detection on AI-assisted writing
→ QuillBot (unique feature)
QuillBot has a dedicated AI Humanizer that rewrites AI-generated text to reduce AI detection scores. Grammarly has no equivalent feature. This is a controversial use case — many universities prohibit submitting AI-generated work, and using a humaniser to bypass detection violates academic integrity policies at most institutions. Understand your institution's AI policy before using this feature.
Academic integrity warning:
Using AI tools to write or substantially rewrite your work may violate your institution's academic integrity policy. Paraphrasing a source with QuillBot and submitting it as your own understanding of that source may count as plagiarism at many universities. Using QuillBot's AI Humanizer to hide AI-generated content is explicitly prohibited at most institutions. Check your university's AI use policy before using any of these features in graded work.
Fact Ledger — verified June 2026, no unsourced stats
The free student setup that actually works: Install Grammarly's Chrome extension (free) — it runs automatically in Google Docs and catches grammar errors as you type. Open QuillBot in a separate tab (free) — when you need to paraphrase a source, paste it there, select Academic mode, and copy the reworded version back into your essay. Total cost: $0. This covers 90% of what most students need from both tools.
Frequently Asked Questions
Is QuillBot better than Grammarly for students?
For most student-specific tasks — paraphrasing research, summarising readings, generating citations, checking plagiarism — QuillBot's Premium plan offers more relevant features at a lower price ($9.99/mo vs Grammarly Pro at $12/mo). However, Grammarly's free tier is better for real-time essay correction because it works inside Google Docs and Word without you needing to copy and paste text. The best setup for most students is both free tiers together at $0.
Does QuillBot have a student discount?
QuillBot does not currently advertise a permanent student discount, but promotional pricing and seasonal discounts (especially around back-to-school periods) frequently bring the annual plan below the standard rate. Check quillbot.com/premium for current pricing. The annual plan (~$4.17/month billed as one payment) is significantly cheaper than monthly billing at $9.99/month.
Does Grammarly have a student plan?
Grammarly does not offer a dedicated student discount tier. The free plan is what most students use — it covers grammar, spelling, and tone detection in Google Docs, Word, and the browser. Grammarly Pro at $12/month (annual) is the paid upgrade, but its extra features (style guides, brand tone, team analytics) are designed for professionals and teams rather than students. Most students get better value from QuillBot Premium if they are going to pay for anything.
Will professors know if I use Grammarly or QuillBot?
Using Grammarly to correct grammar errors in your own writing is generally accepted at most institutions — it functions like a spell checker. Using QuillBot to paraphrase source material or rewrite your own sentences falls into a grey area at many universities — some consider it academic assistance, others consider it a form of contract cheating. Using QuillBot's AI Humanizer to hide AI-generated content is widely considered academic misconduct. Check your institution's specific AI use policy before using either tool in graded work.
Can QuillBot and Grammarly be used together?
Yes — and this is the most effective student setup. Write your essay with Grammarly active in Google Docs (catches errors as you type). When you need to incorporate a research source, paste the relevant passage into QuillBot (paraphrases it in Academic mode). Copy the paraphrased version back into your essay. Grammarly then catches any grammar issues in the paraphrased text. Both free tiers support this workflow at zero cost.
Does QuillBot work for non-English languages?
QuillBot Premium supports paraphrasing in 23 languages including Spanish, French, German, Portuguese, Italian, and others. The free tier is primarily English. Grammarly supports writing assistance in English only (grammar checking and suggestions). For students writing in languages other than English, QuillBot Premium's multilingual support is a meaningful advantage.
