How Does Quillbot Compare to Competitors?

vs Grammarly

Quillbot is excellent for content creation for paraphrasing and summarization, however Grammarly is superior for providing real-time grammar and style suggestions. Grammarly also provides many more options for integration into other applications than Quillbot and is therefore more expensive if you require many paraphrasing functions.

Use Quillbot when you want to rewrite or summarize content and use Grammarly for general assistance with your writing.

vs Wordtune

Both Quillbot and Wordtune are good at paraphrasing; however Quillbot has more options for paraphrasing and also provides a summarizer function. Wordtune is best used for sentence level rewording. Quillbot has a more aggressive price point for group subscriptions than Wordtune.

Use Quillbot when you need a complete AI writing suite and Wordtune when you just need to make a few rewrites quickly.

vs Jasper

Jasper is used for creating longer forms of content based on a prompt; Quillbot can take existing content and transform it. While Jasper is significantly more expensive, it does provide more creative ability for generating content.

Use Quillbot to edit your content, and use Jasper to create new content.

vs Writesonic

Writesonic has a greater number of marketing copywriting tools available than Quillbot; however Quillbot is better for core rewriting tasks.

Use Quillbot to assist with academic and content editing; and use Writesonic to automate marketing.

What are the strengths and limitations of Quillbot?

Pros

QuillBot’s paraphrasing is an excellent mode — it can be used in seven different modes (including fluency, formal, creative) 15.
You have unlimited use of Premium — there are no word limits on how much you can use — even if you're a heavy user, you won't go over your limit 16.
The annual premium pricing model is cost effective — you’ll save as much as 58% by buying annually versus month-to-month 17.
Team pricing for QuillBot includes a discounted price per user — this is a good way to scale QuillBot for teams of five or more people 18.
In addition to paraphrasing, QuillBot has a built-in summarizer that will help you summarize large documents in seconds 19.
Another benefit of QuillBot is its plagiarism detection capabilities — on the Premium version, you get to detect plagiarism in 25,000 words each month 20.
Processing speed is fast — and faster when using the paid version 21.

Cons

Although QuillBot does have a free version, it is extremely limited — you'll be able to paraphrase only 125 words at most 22.
One major drawback of QuillBot is it doesn’t allow you to access its API — therefore, you cannot access QuillBot programmatically 23.
Also, team versions of QuillBot can only be purchased for one year — there is no monthly subscription for groups 24.
Pricing varies greatly depending upon where you find it — we found monthly pricing ranging from $9.95 to $19.95 25.
Unfortunately, QuillBot does not have a mobile app — you’ll need to use it either through your browser or extension 26.
Currently, QuillBot supports very few integration options — primarily just the browser and Google Docs 27.
Support is basic — you’ll need to submit a request via a contact form — there is no live chat option 28.

Who Is Quillbot Best For?

Best For

Content creators and bloggers — However, it is worth noting that paraphrasing with QuillBot helps eliminate repetition in writing and generates new variations of writing quickly 29.
Students and academics — Additionally, QuillBot provides two types of rewriting — Summarizer (for shortening writing) and Formal (for creating formal writing) — along with several other ways to create multiple rewrite options 30.
Small teams (5-50 members) — Tiered pricing per user is more beneficial than individual Premium plans — especially because the dashboard allows all team members to see who is using which version and how many words they've paraphrased 31.
SEO specialists — Rewrite modes offered by QuillBot prevent duplicate content while still allowing writers to convey their intended message 32.
Non-native English speakers — Fluency mode provided by QuillBot also enhances the natural expression of writing 33.

Not Suitable For

Developers needing API — It is worth noting that although QuillBot is great for individuals, it may not be the best option for businesses looking for API integration — if you want API integration, consider OpenAI or Grammarly Business API 34.
Solo casual users — Although QuillBot offers a free version, it is so limited that it's almost useless for everyday writing — and without a significant discount, the monthly Premium price is quite high 35.
Real-time collaborative editing — Because QuillBot does not provide live co-editing, consider using either Grammarly or Google Docs with extensions 36.
Enterprises needing SSO/compliance — Additionally, although QuillBot is a solid product, limited documentation exists regarding its business/enterprise features — Grammarly Enterprise is more robust 37.

What Are the Best Alternatives to Quillbot?

•
Grammarly: Quillbot is a comprehensive artificial intelligence-based writing assistant that provides superior grammar checking, style suggestions, and plagiarism detection capabilities, while being significantly less expensive than many other writing assistants. It is best suited for businesses and professionals who need high-quality proofreading services, but are willing to pay a higher fee for these services compared to the paraphrasing capabilities of Quillbot. (grammarly.com)
•
Wordtune: The primary purpose of WordTune is to provide an AI-based rewriting tool that emphasizes adjusting tone and providing concise rewrites of text. While similar to QuillBot, it provides real-time integration of an editor, and is best suited for email and document editing applications. (wordtune.com)
•
Summarizer.org: Summarizer.org is a completely free artificial intelligence-based text summarizer that can process long pieces of text without any word limit constraints. While QuillBot is simpler and easier to use, Summarizer.org is missing a paraphrasing feature, and is primarily used for quickly creating article summaries, especially when budgets are tight.

•
Paraphraser.io: Dedicated paraphrasing tool with multiple modes like QuillBot. Free tier available, fewer extras; suits users prioritizing rewriting over full suites. (paraphraser.io)
