QuillBot still operates under its own name and branding. You will not see "Course Hero" plastered across the interface. Course Hero folded QuillBot into a broader portfolio of study and writing products, alongside CliffsNotes, which it acquired the same year. It did not merge the products or retire the QuillBot brand.
Read the dashboard row by row. The product ships. The team is stable. The only amber signal is ownership, and an acquisition is not a shutdown. Compare that with a genuinely dead tool on our leaderboard and the difference is obvious.
What happened to QuillBot: a quick timeline
2017 — Launch. QuillBot was founded by University of Illinois students Rohan Gupta, Anil Jason and David Silin as an AI paraphrasing tool, through the university's iVenture Accelerator. It stood out early for natural-sounding rewrites instead of the clunky "spun" text older tools produced.
2017 to 2020 — Growth. QuillBot built a large base of students and professional writers. It added a grammar checker, a summarizer and multiple paraphrasing modes such as Standard, Fluency, Formal and Creative.
January 2021 — Acquired by Course Hero. Course Hero acquired QuillBot and CliffsNotes in the same month. Terms were not disclosed. This was not a distress sale. Course Hero was building an AI-assisted writing and study suite next to its tutoring products.
2021 to 2026 — Continued operation. Since the deal, QuillBot has kept shipping: wider word limits, a citation generator, a plagiarism checker, a Chrome extension and a Microsoft Word add-in. It remains one of the most used AI paraphrasing tools by traffic and reviews. Our full QuillBot story covers each phase in more depth.
Why people think QuillBot might be dead
A few things trigger the "is QuillBot dead" search every month.
- Confusion over the acquisition. Seeing Course Hero in billing or account emails makes some users assume QuillBot was replaced.
- Pricing and paywall changes. As premium-only features grew, tighter free limits looked like a sunset signal.
- General AI tool churn. So many AI writing startups have folded that people now check first, which is sensible.
- Occasional outages. A failed login or a slow paraphrase gets screenshotted and shared as proof of death.
None of these point to an actual shutdown. The core tools work as of this writing.
Is QuillBot still free to use?
Yes. The free tier covers basic paraphrasing, with a lower word limit and fewer rewrite modes, plus basic grammar checking. Premium unlocks:
- Higher or unlimited word counts per paraphrase
- Every paraphrasing mode, including Formal, Academic, Creative and Shorten
- Faster processing
- Full summarizer and citation generator access
- The plagiarism checker
Premium bills monthly, semi-annually or annually, and the annual plan gives the lowest effective monthly cost. Exact prices change, so check QuillBot's own pricing page before subscribing.
What is QuillBot used for?
QuillBot is built for people who need to rewrite, polish or condense text quickly:
- Paraphrasing sentences or paragraphs for clarity, tone or originality
- Grammar and spelling checks while you write
- Summarizing long articles, papers or reports into key points
- Generating citations in APA, MLA, Chicago and other styles
- Checking for plagiarism against web and academic sources
It is popular with students, ESL writers and content marketers who edit drafts rather than generate content from scratch. Academic integrity rules still apply, so check your institution's policy and guidance from bodies such as Turnitin before submitting rewritten work.
Does QuillBot detect AI-generated content?
No. QuillBot is a paraphrasing and writing-improvement tool, not an AI content detector. If you need to test whether text was AI generated, use a dedicated detector instead.
Best QuillBot alternatives in 2026
QuillBot being alive does not make it the only option worth considering.
Grammarly — the strongest all-round competitor. It leads on grammar, spelling, tone and plagiarism detection and suggests rephrasing, though its paraphrasing is less flexible than QuillBot's mode-based rewriter.
Wordtune — focused on sentence-level rewriting with tone and length controls. Similar in spirit to QuillBot's paraphraser, with a different interface and a smaller free tier.
ProWritingAid — aimed at long-form writers and editors, with deeper style and readability reports next to grammar checking.

Verdict: QuillBot is alive in 2026
QuillBot is active, owned by Course Hero, and still shipping. It is safe to use for coursework and client work today. Keep exports of anything important, as you should with any subscription tool, and pair it with a proofreader like Grammarly when accuracy matters most.
FAQ
Frequently Asked Questions
Is QuillBot still active in 2026?
Yes. QuillBot is fully operational in 2026 as part of Course Hero's product lineup. The paraphraser, grammar checker, summarizer, citation generator and plagiarism checker are all live for both free and paid users, and the Chrome extension and Microsoft Word add-in are still maintained.
Did QuillBot shut down or get discontinued?
No. QuillBot did not shut down and was never discontinued. It was acquired by Course Hero in January 2021 and has continued to operate and release updates since, including wider word limits, a citation generator and a plagiarism checker.
Who owns QuillBot now?
Course Hero owns QuillBot after acquiring the company in January 2021, the same month it acquired CliffsNotes. QuillBot still runs under its own brand and interface rather than being merged into Course Hero's main product.
Is QuillBot still free to use?
Yes. QuillBot keeps a free tier with basic paraphrasing at a lower word limit and basic grammar checking. The paid Premium plan raises or removes word limits and unlocks every rewrite mode, the full summarizer, the citation generator and the plagiarism checker.
Can QuillBot detect AI-generated content?
No. QuillBot rewrites and improves text but does not detect AI-generated writing. If you need to test whether a passage was produced by an AI model, use a dedicated AI detection tool instead of QuillBot.
What is the difference between QuillBot and Grammarly?
QuillBot specialises in paraphrasing with multiple rewrite modes, while Grammarly focuses on grammar, spelling, tone and plagiarism checking with lighter rephrasing features. Many writers run both: QuillBot to rewrite, Grammarly to proof the final draft.
Why do people search whether QuillBot is dead?
Mostly because of the Course Hero acquisition showing up in billing emails, tightened free-tier limits, and occasional login or outage errors. Combined with the high failure rate of AI writing startups, those signals make users check before trusting the tool with coursework or client work.
Is QuillBot safe to rely on for coursework in 2026?
Technically yes, since the product is active and maintained. The real risk is academic policy rather than shutdown risk: many institutions restrict paraphrasing tools on submitted work. Check your school's rules, keep your own drafts, and use QuillBot to improve your writing rather than to disguise someone else's.
