3 Things Quillbot AI Chat Does Well

• AI Detector: You can use this tool to check if something was written by a person or an AI, which is helpful for students and teachers trying to spot AI-generated work.
 
• Grammar Checker: Includes a grammar checking feature that helps make your writing more accurate; some users even find it more reliable than other grammar tools.
 
• Humanize AI Text: Need your AI-generated content to sound more like a real person? This feature helps make your text less obviously AI-created.

5 Worst Things About Quillbot AI Chat

• Terrible Customer Service: If you ever want to cancel or get your money back, good luck! Quillbot support barely replies and makes it super hard to get refunds, so you can end up just losing your money.
 
• Expensive Subscriptions with Vanishing Credits: You pay a lot every month, but any unused credits just disappear. They don’t roll over, so you’re basically throwing money away for credits you paid for but didn’t use.
 
• AI Detection Is Clueless: Their AI detector says your work is AI-written, even when you wrote it yourself! That’s so annoying. You can’t really trust whether it’s telling the truth or just messing things up.
 
• Humanizer Tool Doesn't Work: The humanizer totally fails sometimes. Even after using it, the AI detector still says your text is 100% AI. So, you pay extra for a feature that just doesn’t do what it promises.
 
• Paraphraser Quality Is Hit or Miss: Sometimes the paraphraser spits out weird sentences that don’t make sense. You still have to fix a bunch of errors yourself, which defeats the whole point of using an AI to help.
 

What Does Quillbot AI Chat Cost?

• Free Plan - This one's $0 a month, so you don’t pay anything. But honestly, you can only paraphrase up to 125 words at a time and just in 2 modes. You get basic grammar fixes and a limited AI detector, but it feels a bit restrictive and pretty bare-bones for real work.
 
• Premium Plan - This costs $4.17 a month if you pay for a whole year up front. You get unlimited paraphrasing, all the modes, advanced grammar help, and unlimited AI detector. I like that you get a 3-day money-back guarantee, but this plan still might feel pricey if you only use it sometimes.
 
• Team Plan - No set price here since it depends on your team, but it includes everything in Premium and throws in stuff like usage metrics, user management, and personal support. It’s handy for groups or companies, but probably overkill if you’re just working solo or don’t need managing features.
 
• Should you buy Quillbot AI Chat? I’d say hold off unless you really need the unlimited features, because the free plan is way too limited and the paid options get costly if you don’t use them a lot.

Quillbot AI Chat Review - What Does it Get Right?

1. AI Detector:
   • Helps with checking if something is written by AI: You can copy and paste text, and the tool tells you if it's made by AI or a real person.
    
   • Useful for school and research: Users like to use it for checking if classmates or teachers use AI in their assignments or grading.
    
   • Pretty accurate: People mention that it catches a lot of AI stuff, though not every single thing, so sometimes you should double-check.
 
2. Grammar Checker:
   • Easy way to fix mistakes: Lots of users say it catches grammar errors, making your work sound more correct and clear.
    
   • Preferred over other tools: Some students feel it does a better job than Grammarly at finding problems in their writing.
    
   • Saves time when editing: Instead of guessing or googling grammar rules, you just run your writing in the checker.
 
3. Humanize AI Text:
   • Makes AI text seem more natural: When you have stuff made by AI, this feature can help change the wording so it sounds more like a person wrote it.
    
   • Helpful for avoiding AI detection: Some reviewers say this comes in handy so teachers or AI tools don't guess your text is AI-made right away.
    
   • Works for lots of assignments: People use it on research, essays, and schoolwork, but you still have to double-check the results.

Quillbot AI Chat Review - What Does it Get Seriously Wrong?

• Terrible Customer Service
  • If you ever try reaching out to Quillbot’s support, they barely reply or sometimes don’t even respond. I’ve faced this myself, and trust me, it’s super frustrating when you just want help.
   
  • When you want to cancel or get your money back, the whole process just drags on. Users say it’s hard to actually get a refund or cancel easily, so you could end up losing your cash for nothing.
   
  • Even if you’re in a rush for a reply, Quillbot support tends to leave you hanging, which just isn’t cool if you actually need fast help with your subscription or account.
 
• Expensive Subscriptions with Vanishing Credits
  • You pay a hefty price every month, but if you don’t use all your credits, they just wipe them out. I always hate this because you never get what you pay for if you miss a month.
   
  • Those leftover credits don’t carry over at all. If you forget to use them, they vanish, and you’re basically wasting your money on nothing.
   
  • Even if you paid the full amount, you get stuck with this unfair system that only benefits them and leaves you losing out almost every billing cycle.
 
Here's a review by Dilmith Hansana LK talking about the service:
 

“Rated 1 out of 5 stars its sucks i brough this premium service… its sucks i brough this premium service and use paraphrase and use the same ai detector and even it shows its AI generated 84% why u nuy premium service when its like this never buy this shit” ― Dilmith Hansana LK

 
• AI Detection Is Clueless
  • Quillbot’s AI detector calls your stuff “AI-generated” even when you write it yourself. People complain that it messes up a lot and can’t really tell what’s written by a person or by a robot.
   
  • I’ve seen my own writing get flagged as AI. That makes it super annoying when you need to prove your work is original but Quillbot just labels it wrong for no reason.
   
  • There isn’t really a fix unless they totally revamp the AI. For now, you just can’t count on it to be accurate, no matter what the official website promises.
 
• Humanizer Tool Doesn't Work
  • The humanizer tool often fails big time. Users say and I’ve noticed it too, the AI detector still marks your writing as AI-generated, even after you run it through this tool.
   
  • You end up paying more for the “humanizer” feature, but honestly, it just doesn’t do what you expect. That’s pretty disappointing for something that’s supposed to help.
   
  • If you want your work to look more human, this tool just won’t help. It even gives you 100% AI-detected results sometimes — which is such a rip-off.
 
• Paraphraser Quality Is Hit or Miss
  • The paraphraser spits out weird sentences sometimes that make no sense. You still have to fix lots of errors yourself, which takes up your time and energy.
   
  • A good AI tool should actually help you, but here you keep spotting grammar mistakes and bad word choices in the paraphrased text. That makes it really unreliable.
   
  • I noticed, like others, that some sentences come out so strange you need to totally rewrite them — which defeats the entire purpose of even using Quillbot in the first place.

What Does Quillbot AI Chat Cost?

• So, the Free plan sounds nice since, well, it's free. But you'll run into its limits real quick. You can only paraphrase up to 125 words at a time, which isn't even a decent-sized paragraph if you ask me.
 
• You only get standard and fluency modes, so if you wanted more advanced rewrites, you're out of luck. Also, grammar correction is super basic—you miss out on smarter suggestions.
 
• The humanize feature is stuck in basic mode and the AI detector is limited, so you're pretty much forced to upgrade if you want to use any real features. I tried the free stuff, and honestly, it felt like a teaser—it's just there to make you want to pay up.

• Now this is the plan they really want you to buy. But look closely—I have, and here's the thing: you have to pay upfront for a whole year, so it's not even a “monthly” thing. That's $50+ all at once.
 
• Sure, they unlock unlimited paraphrasing and all the fancy modes, but you still keep paying every month (well, every year, but same idea), and if you take a break or have a slow month, you still lose out.
 
• You get some extra perks: advanced grammar help, custom summaries, a fancier humanizing feature, and unlimited AI detector usage. But let's be real, for what you're getting, it adds up fast—especially if you ever decide not to use it for a bit.
 
• From my experience, the so-called “premium” features sound cool, but a lot of folks never actually use everything they’re paying for. And the refund? It's only for new users and just 3 days—blink and you'll miss it.

• This one's for organizations or groups. You get team usage metrics, user management, priority support, and centralized billing. Honestly though, most people never need this stuff—unless you’ve got a whole squad cranking out content.
 
• You still have to pay every single month, no matter what. There’s a discount if you have 5+ people, but in the end, it’s another rent-you-can’t-skip situation. Even if you pause, it’s just a temporary stop—you’ll keep paying as soon as you use it again.
 
• The features are just the premium ones with a dashboard slapped on top. If you're a regular writer, it's definitely overkill. I tried exploring this for a group project, and it ended up being way more trouble than it was worth.

• Quillbot AI Chat keeps you locked into paying over and over for the same stuff—even if you don't use your plan fully. Your money is gone each month, just like paying rent for a place you barely visit.
 
• Honestly, you can find better deals out there. One example: AIDetectPlus gives you AI chat with all the good stuff (like GPT-4, Claude, Gemini and more), a smart AI detector, humanizer, essay writer, plagiarism checker, and extra tools—all for a simple one-time payment starting at just $9 instead of a never-ending subscription.
 
• The best part? Your credits NEVER EXPIRE. Buy 5,000 words for $9 one time, use them when you want, and you only pay again if you really need more. That's way better than Quillbot AI Chat, where you’re stuck paying forever, even if you’re on vacation or don’t write much this month.

What are some Quillbot AI Chat alternatives?

#1 - Quillbot AI Chat vs AIDetectPlus

• Both tools help you with writing and checking if something is AI or not, but they work pretty differently:
  • Quillbot AI Chat is mostly about paraphrasing, grammar checking, and a basic AI detector. It’s good for quick fixes and making your writing sound a bit more natural.

  • Simple grammar fixes: If you just want to fix a few sentences or check grammar real quick, Quillbot is easy to use.

#2 - Quillbot AI Chat vs Deep AI

• Both Quillbot AI Chat and DeepAI let you chat with AI and fix your writing, but they have some pretty big differences:
  • Quillbot AI Chat focuses more on fixing up your text—it’s got grammar tools, an AI detector, and features for making AI writing sound more like a real person.
  • DeepAI Chat is more of a creative playground. Besides chatting, you can make pictures, music, videos, and even use voice—with everything rolled into one website.
 
• Where is DeepAI Chat Better?
  • Creative stuff all in one place: You get tools for images, videos, music, stories, and voice, not just chat or writing help.
  • Easy to try for free: You can use a bunch of features on DeepAI without even signing up.
  • Flexible payment options: Just want to try it out? Buy pay-as-you-go credits, or get the Pro plan for $4.99/month for bigger quotas on all the creative tools.
  • No switching between apps: It’s all together—chat, content makers, and voice features—so you don’t have to keep bouncing between different sites.
 
• Where is Quillbot AI Chat Better?
  • Grammar and AI writing help: Quillbot’s pretty handy if you mostly care about checking for grammar mistakes or if something was written by AI.
  • If making your writing sound less robotic is your goal, Quillbot’s humanizer feature tries to help with that.

#3 - Quillbot AI Chat vs Duck AI

• Both Quillbot AI Chat and Duck AI are cool for chatting with AI, but they're kinda meant for different stuff:
  • Quillbot AI Chat is more of a writing-helper tool—it's got things like grammar checks, AI detectors, and options to make your writing sound less robotic, all packed in one spot.
  • Duck.ai (from DuckDuckGo) is really focused on privacy and lets you chat with lots of different AI models (like GPT‑4o mini, Claude 3 Haiku, and Llama 3.3), all without logging in or giving up any personal info.
 
• Where is Duck.ai Better?
  • Super private: You don’t need to sign up, and none of your chats get saved anywhere. It’s all just local to your device.
  • Lots of AI models: You can try out different AIs in the same chat and switch between them whenever you want.
  • Completely free: You get super high daily limits and don’t have to pay a thing—there’s no sneaky paywall.
  • Easy to tinker: Change the tone or how long the AI replies, and you never have to fill out some boring signup form.
 
• Where is Quillbot AI Chat Better?
  • Writes and edits for you: If you need help making your writing better, want to spot grammar mistakes, or just want your words to sound more “human,” Quillbot has those tools built in.
  • AI detector: You can see if something looks like it was written by an AI, which can be handy for school or work.
 
• If you want a privacy-focused chat and lots of AI models for free, Duck.ai is awesome. If you need help with writing, grammar, and making your words sound just right, Quillbot AI Chat is worth checking out—just make sure you really need those features before you pay.

Is Quillbot AI Chat Legit?

• Reason #1: Awful Customer Service: If you ever need help, good luck getting it. Quillbot’s support barely answers, and it feels impossible to get your money back if anything goes wrong. Trust me, I spent ages just waiting for basic answers.
 
• Reason #2: Expensive Plans & Vanishing Credits: You pay a lot, but if you don’t use your credits, they’re just gone. They don’t roll over, so some months you basically pay for nothing.
 
• Reason #3: Flawed Tools That Just Don’t Work: The AI detection gets it wrong all the time—even on stuff I wrote myself! And that “humanizer” tool? It fails to pass their own AI checks, so you’re left fixing errors anyway. What’s even the point?

“I’m disappointed with the AI Detector… I wrote my text manually without using any AI tools, but QuillBot still marked it as AI-generated. This shows the detector is not reliable yet. I hope the team can improve its accuracy.” ― Zee ID

• #1 Fast, Accurate AI Chat with Top Models: With AIDetectPlus, you get built-in AI chat using GPT‑4, Claude, Gemini—basically all the good stuff. Ask anything and get real answers instantly. I use it for brainstorming and research without ever swapping tools.
 
• #2 Credits NEVER EXPIRE: Buy credits once, keep them forever. Unless you use them up, you don’t ever lose your money to some silly “monthly reset.”
 
• #3 Way better customer support: When I had questions, a real person actually replied, usually in a few hours. No getting ghosted or endless waiting like Quillbot.
 
• #4 Built-in AI Chat as Part of an All-in-One Suite: AIDetectPlus isn’t just smart AI chat. You also get AI detection, humanizer, plagiarism checks, essay tools, paraphrasing, and even PDF summaries—all in one place. Whether you’re a student, marketer, or researcher, it’s everything you need. Just poke around the menu above and you’ll see.
