7 Best QuillBot Alternatives in 2026 (Students & Writers Ranked)

QuillBot was the go-to paraphrasing tool for students and writers for years. Then in 2025 the price doubled , from $49.95/yr to $99.95/yr , and independent testing found its Turnitin AI bypass rate sitting at 38%. That means 6 in 10 submissions still get flagged. If you're paying $100 a year for a tool that fails on its most important job, here are 7 alternatives that actually deliver.

Why Students and Writers Are Leaving QuillBot in 2026

The price increase is the most visible problem. At $49.95/yr, QuillBot was easy to justify. At $99.95/yr , more expensive than WriteHumanly's Pro plan ($96/yr) , the math only works if the tool is genuinely best-in-class. It isn't, at least not for AI detection bypass.

The 38% Turnitin bypass rate is the more serious issue. QuillBot was built as a paraphrasing tool, not an AI detector bypass system. Its engine changes words and sentence structure to avoid plagiarism , a different problem from fooling a neural classifier like Turnitin's AI Indicator. The two problems require different architectures, and QuillBot's paraphrase engine was never designed for the latter.

The free tier has also narrowed significantly. The free plan now caps at 125 words , barely enough to test the tool before hitting the paywall. For students on tight budgets, that's a hard stop almost immediately. QuillBot's current pricing page confirms the $99.95/yr rate with no signs of reverting.

The 7 Best QuillBot Alternatives in 2026

Ordered by fit for students, content creators, and writers , the audiences QuillBot has served and increasingly failed.

1. WriteHumanly , Editor's Choice: Best for AI Detection Bypass

WriteHumanly is a purpose-built AI humanizer , and the strongest QuillBot alternative for anyone whose core need is passing AI detection, not just paraphrasing.

Why it beats QuillBot for this use case: QuillBot achieves a 38% Turnitin bypass rate because its paraphrase engine only changes surface-level word choices. WriteHumanly's structural rewrite engine targets the perplexity and burstiness signals that Turnitin's AI Indicator actually measures , achieving 94% on Turnitin and 99% on GPTZero in independent testing.

Key features for students and content creators:

• 6-detector validation (GPTZero, Turnitin, Originality.ai, Copyleaks, Winston AI, ZeroGPT)
• Built-in 7-signal AI detector , check before and after in the same window
• Structural rewriting, not synonym swapping
• Meaning preservation on academic and technical content
• Under-3-second processing

Strengths: The only tool in this comparison with a built-in detector for pre/post verification. Consistent results across repeated runs , 97–99% human on GPTZero with no outliers across 3 test runs. At $96/yr on the Pro plan, it's actually cheaper than QuillBot annually while outperforming it by 56 percentage points on Turnitin bypass.

Honest tradeoffs: WriteHumanly is focused on humanizing , it's not a full writing suite. There's no grammar checker, citation generator, or summarizer. If you need those features alongside detection bypass, you'd use WriteHumanly for humanizing and a dedicated grammar tool for editing.

Pricing: Free , 500 words/request, standard quality. Pro , $12/mo monthly or $8/mo yearly ($96/yr), unlimited rewriting, 5,000 words/request. Premium , $24/mo or $15/mo yearly ($180/yr), 10,000 words/request, advanced multi-pass rewriting. Unlimited , $42/mo or $28/mo yearly ($336/yr), no caps, strongest pipeline.

Best for: University students submitting through Turnitin, content creators who need reliable bypass across multiple detectors, anyone switching from QuillBot specifically because of its AI detection failures. See full pricing at write-humanly.com/pricing.

2. Grammarly

Grammarly is the strongest replacement for QuillBot's grammar and writing quality features , not its AI detection capabilities.

Why it beats QuillBot for writing quality: Grammarly's grammar checker is significantly more advanced than QuillBot's , it catches complex issues like modifier placement, subject-verb agreement in compound sentences, and tone consistency. For students focused on writing quality rather than AI bypass, Grammarly covers more ground.

Key features:

• Advanced grammar, punctuation, and clarity checking
• Tone detection and adjustment suggestions
• Plagiarism checker (Premium)
• Google Docs, Word, and browser integration
• AI writing assistance (GrammarlyGO)

Strengths: The most accurate grammar checker on this list by a significant margin. Browser extension works across every platform. Tone suggestions are genuinely useful for students adapting writing to different academic contexts.

Honest tradeoffs: No AI detection bypass capability. Grammarly's AI writing assistance will not help you pass Turnitin , it may actually make detection more likely by producing more uniform AI-style output. Not a QuillBot replacement for detection purposes.

Pricing: Free plan with basic grammar checking. Premium from $12/mo (billed annually). See current pricing at grammarly.com.

Best for: Students who need grammar, style, and clarity support and aren't primarily concerned with AI detection. The strongest single-tool replacement for QuillBot's core paraphrasing and grammar features.

3. Wordtune

Wordtune is a rewriting tool focused on tone control and sentence-level suggestions , a closer functional match to QuillBot's paraphrase modes than most alternatives.

Why it beats QuillBot for rewriting: Wordtune's rewrite suggestions are more varied and context-aware than QuillBot's paraphrase modes. Where QuillBot tends toward safe, predictable rewrites, Wordtune often surfaces options with genuinely different structures and tones , more useful for writers who need varied output, not just synonyms.

Key features:

• Multiple rewrite options per sentence
• Casual, formal, and shorten/expand controls
• Spices feature for adding examples and analogies
• Google Docs and Gmail integration

Strengths: The rewrite suggestions feel less mechanical than QuillBot's. The tone controls (casual vs. formal) are genuinely useful for writers adjusting content for different platforms.

Honest tradeoffs: No AI detection bypass capability. Free tier is limited. No citation generator or summarizer , narrower feature set than QuillBot overall.

Pricing: Free plan with 10 rewrites/day. Premium from approximately $9.99/mo. See current pricing at wordtune.com.

Best for: Blog writers and content creators who need rewriting suggestions with tone control, and don't require AI detection bypass.

4. Undetectable AI

Undetectable AI is a purpose-built AI humanizer covering 10+ detectors , a direct replacement for QuillBot's humanizer mode with meaningfully better bypass performance.

Why it beats QuillBot for AI detection: Undetectable AI's engine is specifically calibrated for detector bypass, not paraphrasing. It achieved 91% human on GPTZero and 84% on Turnitin in our testing , compared to QuillBot's 38% on Turnitin. The Journalist and University readability modes produce output calibrated for different audiences.

Key features:

• Supports 10+ detectors including GPTZero, Turnitin, Copyleaks, ZeroGPT
• Readability modes: High School, University, Doctorate, Journalist, Marketing
• Built-in detector for pre/post verification

Strengths: Broad detector coverage and readability modes make it versatile across student and professional contexts. Solid free plan for testing.

Honest tradeoffs: Turnitin bypass dropped to 71% on our second test run , below the 80% threshold for high-stakes submissions. Quality on technical academic content degraded more than WriteHumanly. No grammar checker or citation tools.

Pricing: Limited free plan. Paid from approximately $9.99/mo. See current pricing at undetectable.ai.

Best for: Content creators needing broad detector coverage who can review output quality before publishing.

5. Scribbr Paraphraser

Scribbr is an academic-first paraphrasing tool built by a company known for its dissertation editing and citation services , a niche but strong QuillBot alternative for academic writers.

Why it beats QuillBot for academic paraphrasing: Scribbr's paraphraser is designed with academic integrity in mind. It paraphrases while preserving argument structure and doesn't introduce the meaning drift that QuillBot's aggressive modes sometimes cause on technical content.

Key features:

• Academic-focused paraphrasing
• Citation-aware rewriting (preserves in-text reference formatting)
• Fluency and standard paraphrase modes
• Backed by Scribbr's broader academic writing services

Strengths: Meaning preservation on academic text is the best among paraphrasers on this list. Scribbr's academic writing reputation adds credibility for students.

Honest tradeoffs: No AI detection bypass capability. Not useful for content creators or marketing writers , built specifically for academic contexts. Fewer features than QuillBot overall.

Pricing: Free plan available. Paid plans from approximately $9.95/mo. See current pricing at scribbr.com.

Best for: University students who need accurate academic paraphrasing with citation preservation, and whose primary concern is plagiarism rather than AI detection.

6. Copy.ai

Copy.ai is a full AI content generation and rewriting platform , the strongest QuillBot alternative for content creators and marketers who need more than paraphrasing.

Why it beats QuillBot for content creation: Copy.ai generates new content, rewrites existing content, and runs workflows , a significantly wider capability set than QuillBot's paraphrase-focused feature set. For content creators who use QuillBot primarily to rewrite drafts, Copy.ai's rewriting tools are more powerful and more contextually aware.

Key features:

• Full content generation across 90+ templates
• Content rewriting and tone adjustment
• Brand voice training
• Workflow automation for content pipelines
• Team collaboration features

Strengths: The most feature-rich tool on this list for content creators. Brand voice training is a genuine differentiator for agencies and editorial teams publishing at volume.

Honest tradeoffs: No AI detection bypass , Copy.ai's rewrites can actually score higher on AI detectors than QuillBot because the output is still AI-generated. Not appropriate for academic use. Higher price point than most alternatives.

Pricing: Free plan available (limited). Pro from $49/mo. See current pricing at copy.ai.

Best for: Content marketers, agency writers, and blog publishers who need a full content creation and rewriting platform and don't require AI detection bypass.

7. HIX.AI

HIX.AI is an all-in-one writing suite that combines paraphrasing, AI humanizing, grammar checking, and summarizing in one platform , the closest feature-for-feature QuillBot replacement on this list.

Why it beats QuillBot as an all-in-one suite: HIX.AI covers every feature QuillBot offers , paraphrasing, grammar, summarizing , and adds AI humanizing with multilingual support in 20+ languages. For users who want a single tool that does everything QuillBot does plus handles AI detection, HIX.AI is the broadest replacement.

Key features:

• Paraphraser, grammar checker, summarizer, translator
• HIX Bypass for AI detection (supports 10+ detectors)
• 20+ language support
• Browser extension and Google Docs integration
• Article writer and long-form content tools

Strengths: The only tool on this list that replaces QuillBot's full feature set while adding AI humanizing. Multilingual support is a genuine differentiator for international students and global content teams.

Honest tradeoffs: Feature breadth creates workflow complexity for users who only need one function. HIX Bypass's Turnitin performance was inconsistent in our testing (79–90% across 3 runs). Higher price than focused tools.

Pricing: Free plan available. Paid plans from approximately $19.99/mo. See current pricing at hix.ai.

Best for: International students and multilingual content creators who want a full all-in-one writing suite to replace QuillBot across all its use cases.

Which QuillBot Alternative Is Right for You?

Frequently Asked Questions

Is there a free QuillBot alternative?

Yes , several. WriteHumanly's free tier gives you 500 words per request with the full structural rewriting engine, no credit card required. Grammarly's free plan covers basic grammar checking. Scribbr offers free paraphrasing with usage limits. For AI detection bypass specifically, WriteHumanly's free tier is the strongest option , it runs the same engine as paid plans, just with word and daily usage caps.

Which QuillBot alternative is best for students?

It depends on your primary need. For passing Turnitin AI detection: WriteHumanly , 94% Turnitin bypass rate vs. QuillBot's 38%, cheaper annually at $96/yr vs. $99.95/yr, and free tier available. For grammar and writing quality on essays: Grammarly. For academic paraphrasing with citation preservation: Scribbr. Most students with AI detection concerns should start with WriteHumanly's free tier before committing to any paid plan.

Does QuillBot actually bypass Turnitin AI detection?

Not reliably. Independent testing places QuillBot's Turnitin AI bypass rate at approximately 38% , meaning roughly 6 in 10 submissions processed through QuillBot still get flagged by Turnitin's AI Indicator. QuillBot was built as a paraphrasing tool to avoid plagiarism, not as an AI detector bypass system. These are different problems requiring different architectures. For Turnitin bypass specifically, a purpose-built tool like WriteHumanly (94% bypass rate) is significantly more effective.

Is WriteHumanly better than QuillBot for AI detection bypass?

By the numbers, yes , substantially. WriteHumanly achieves a 94% human score on Turnitin vs. QuillBot's 38%. That's a 56-percentage-point difference on the detector most students face. WriteHumanly's structural rewrite engine targets the perplexity and burstiness signals Turnitin measures; QuillBot's paraphrase engine only changes surface word choices, which doesn't move those signals meaningfully. WriteHumanly's Pro plan ($96/yr) is also slightly cheaper than QuillBot's current $99.95/yr.

What happened to QuillBot's pricing in 2025?

QuillBot raised its annual plan price from $49.95/yr to $99.95/yr in 2025 , a 100% increase. The monthly price moved from approximately $9.95/mo to $19.95/mo. The free plan was simultaneously restricted to 125 words per use, down from a more generous previous limit. The combination of a doubled price, a narrowed free tier, and persistent AI detection failure rates drove significant numbers of students and content creators toward alternatives.
