Students get flagged for AI when they don’t use it, AI-generated essays slip through unnoticed, and detection tools contradict each other on the same text.
This is the reality of AI detection in 2025, and Wordvice AI detector is right in the middle of this dilemma.
While the platform offers multiple tools, including its proofreading system and integrations like the Wordvice Grammar Checker AI and the Wordvice AI Grammar Checker, its detection accuracy still leaves major gaps.
We evaluated the platform using the same testing methodology ZDNet used in ranking top detectors. Read the full analysis below.
Key Takeaways
- Wordvice AI works best for academic writers who need proofreading and paraphrasing, not AI detection.
- Free plan offers 5,000 words monthly; Premium costs $19.95/month with unlimited usage.
- The AI detector achieved only 55% accuracy in our testing, which is barely better than guessing
- The tool produces frequent false positives, flagging human academic writing as AI-generated
- It also missed 75% of lightly AI-assisted content and 50% of heavily AI-edited text.
- Premium features such as intensive editing, plagiarism checker are locked behind a paywall with no trial.
What Is Wordvice AI?
Wordvice AI is an online writing assistant that combines multiple editing tools into one platform.
Originally built by Wordvice, a professional editing service with over 500 qualified editors, the AI version launched as an automated alternative for writers who need quick revisions without hiring a human editor.
The platform uses GPT-powered technology along with custom language models trained on academic writing.
Never Worry About AI Detecting Your Texts Again. Undetectable AI Can Help You:
- Make your AI assisted writing appear human-like.
- Bypass all major AI detection tools with just one click.
- Use AI safely and confidently in school and work.
Unlike standalone grammar checkers, Wordvice AI offers six integrated tools: proofreading, paraphrasing, summarizing, translating, plagiarism detection, and AI content detection.
The company primarily targets academic users: students working on essays, researchers preparing manuscripts, and professionals writing business documents.
That focus shows in the “Academic” mode options, which adjust suggestions based on scholarly writing conventions.
Core Features Overview
Here is an overview of the core features of the tool:
AI Proofreader
The Wordvice AI proofreader serves as the platform’s centerpiece. It scans text for grammar errors, spelling mistakes, punctuation issues, and style problems. What sets it apart is the revision mode system.
The light mode works on minor corrections only, the standard mode provides a balanced editing for clarity, the intensive mode is a premium feature, which offers deep revisions for flow and structure and finally, the concise mode that shortens wordy passages
While the free version limits you to 500 words per submission and 5,000 words monthly, the premium removes these caps and unlocks all modes.
AI Paraphraser
The Wordvice AI paraphraser rewrites sentences to improve vocabulary and avoid repetition.
It offers multiple modes including Academic, Fluency, and Creative.
During our testing, it successfully changed phrasing while maintaining original meaning, although its outputs sometimes felt slightly robotic.
AI Summarizer
This feature condenses long documents into bulleted key points.
It works on simple content but not complex technical writing or nuanced arguments. In that manner, the summaries are usually superficial instead of analytical.
AI Translator
The Wordvice AI translator supports more than 40 languages and is powered by DeepL and other sophisticated models.
The quality of translations is good with more frequent language pairs (English-Spanish, English-French) and less accurate with the less frequent ones.
AI Plagiarism Checker
The plagiarism detector scans over a billion online sources, including research databases and public journals.
However, it’s completely locked behind the Premium paywall with no free trial. This is a major limitation, especially if you just want to test accuracy before committing.
AI Detector
The AI content detector identifies text potentially written by ChatGPT, Gemini, Claude, and other language models.
It provides sentence-level analysis showing which portions appear AI-generated.
Wordvice AI Pricing and Plans
Below is a table showing the pricing and plans of this tool and the limitations of each plan:
| Plan | Price | Features | Limitations |
| Basic | Free | Light & Academic proofreading modes, limited paraphrasing, translator, summarizer | 500 words per submission, 5,000 words/month total, no plagiarism checker, no AI detector. |
| Premium | $19.95/month ($16.65/month if billed semi-annually) | All proofreading modes, unlimited paraphrasing, 20 pages plagiarism checks monthly, and AI detector access. | Up to 1 million words/month |
| Team | $19.95/month per user (annual billing only) | All Premium features, multiple user seats, admin dashboard | Requires annual commitment |
Although the cost is competitive, it is more expensive than some AI tools in the market.
It is disappointing that there is no free plagiarism checker trial, so you must pay a fee to test its efficiency.
How Wordvice AI Works
Using Wordvice AI is straightforward.
Here is a step-by-step method of how to go about it:
- Create an account or use it as a guest. However, it is important to note that using it as a guest offers limited features.
- Paste or upload your text into the editor
- Select your tool. This can range from proofreader to paraphraser to detector
- If applicable, choose a revision mode.
- Review suggestions in the editor with tracked changes
- Accept or reject the individual edits
The platform underlines the problems with various colors: red color indicates grammar mistakes, blue color indicates style recommendations, and purple color indicates vocabulary recommendations.
With a single click, you may accept any changes or look through them one by one.
For the AI detector, you simply paste text and receive a percentage score showing how much content appears AI-generated, with sentence-level highlighting.
Our Own Test
Our testing methodology draws from ZDNet’s widely referenced benchmark study that evaluated AI detection tools.
The approach uses many text samples across multiple categories to measure accuracy, consistency, and real-world performance, and this rigorous testing found that only five tools correctly identified AI text every time.
Undetectable AI achieved 100% accuracy in this study, making it our benchmark for comparison.
Results
For this review, we wanted to see how well Wordvice AI performs against real detection tools that content creators actually face.
We generated AI content, ran it through Wordvice Paraphraser, then tested the output using Undetectable AI’s detector, which provides consensus scoring across multiple detection engines, including Turnitin, GPTZero, Copyleaks, and Originality.ai.
We discovered that despite its paraphrasing ability, the AI was obvious to human readers and to Undetectable AI, as it was flagged at 98%.
Additionally, samples where we used the tool to fix a few grammar mistakes or adjust word choice were frequently flagged as heavily AI-generated.
This is a major problem because most writers use AI tools for basic editing help. Wordvice AI wasn’t able to rewrite and paraphrase properly.
To put this to the test, we ran the flagged text through Undetectable AI’s Humanizer to see if the “AI-like” qualities Wordvice couldn’t paraphrase properly can be humanized by Undetectable AI.
After humanization, which rewrites text to match natural writing patterns, the same content passed Undetectable AI’s detector with scores under 10%.
This confirmed that Wordvice was paraphrasing phantom patterns, not real AI signatures.
This is worrying since you’ll need an accurate tool to help you out.
Whatever the case may be, consider using our AI Detector and Humanizer to ensure that your material bypasses AI Detectors.
However, if any element of your writing is tagged as AI, you can humanize it to make it sound more human.
Pros and Cons of Wordvice AI
This is our well-rounded look at the pros and cons of Wordvice AI, based on user feedback, reviews, and analyses.
Use this to decide whether it’s a tool you want to use or not.
Pros
Below are the pros of Wordvice AI:
- Clean and Intuitive Interface: You open Wordvice AI and immediately understand what to do. There are no buried settings, no confusing navigation menus or tutorials required. All you have to do is paste your text, pick a tool, and you’re done.
The interface uses color coding effectively: red for errors, blue for style, and purple for vocabulary. That way, you can scan through suggestions quickly.
For students and professionals who just want to fix their writing without learning complex software, this simplicity is valuable.
- Multiple Revision Modes: Light mode keeps your own voice and corrects unambiguous errors, Intensive mode rewrites awkward sentences and makes them easier to read, and Concise mode is particularly useful when it comes to writing academic papers that are drowning in qualifiers and redundant phrases.
- Ms Word Integration: The Ms Word add-on implies that you do not need to copy 50 pages into a web interface, make changes and reformat. You can simply edit them directly in your document. For dissertation chapters or lengthy reports, this matters. The add-on preserves your formatting, tracks changes like Word’s built-in editor, and lets you accept or reject suggestions without switching between applications.
Cons
Below are the cons of Wordvice AI
- AI Detection Can be Unreliable: The AI detector produces inconsistent results and struggles with false positives, with accuracy varying significantly based on content length and complexity.
Our testing has shown the detector producing dramatically different results for the same 100% human-written content, suggesting potential reliability issues.
This isn’t so great when you’re relying on it for important decisions.
- Plagarism Checker is Paywalled: The plagiarism detection feature is completely locked behind the Premium paywall. You can’t test it with even one document unless you commit $19.95/month.
This can get frustrating because plagiarism checkers vary wildly in database coverage and accuracy.
For instance, while Turnitin works well because it has academic databases, random online checkers miss most plagiarism because they only search public websites.
Without testing Wordvice’s plagiarism checker, you don’t know which category it falls into.
- Slow Processing: Documents over 1,000 words regularly take 20-30 seconds to process. While that might not sound long, it breaks your workflow. You paste text, click analyze, and then watch a loading screen instead of working.
Competitors like Grammarly process text almost instantly, even for multi-thousand-word documents. Wordvice’s slower processing suggests that there are either less efficient algorithms or underpowered servers.
Wordvice AI vs. Competitors
Wordvice AI has some competitors that we’ve noted and made adequate comparisons with.
| Wordvice AI | Undetectable AI | Grammarly |
| It offers AI detection, paraphrasing, summarizing, proofreading and writing tools | Primarily rewrites and paraphrases AI traces, while offering business solutions | It offers writing tools first, with detection as support |
| Users report false positives, and many reveal that its results are inconsistent | Its detection is 100% as seen in industry tests and peer-reviewed studies | Showed 100% detection of fully AI-generated text in some studies |
| This tool is good when you want a one-platform solution (write, check, fix) | This tool works for all writing situations and academic needs, as well as business needs. | Best when your primary goal is writing (paraphrase, grammar), and you want occasional AI detection in the same tool |
| Offers a free version, with limited features | If your goal is humanizing content, Undetectable AI is more specialized and justifies paying more. | It is very pricey and best for someone doing a lot of writing/editing. |
Can Wordvice AI Detect AI-Edited or Paraphrased Text?
Our testing revealed that Wordvice AI struggles significantly with AI content that’s been edited or paraphrased to sound more natural.
When we ran AI-generated samples through humanization tools before testing them, Wordvice AI’s detection rate dropped to below 30%.
Tools like the Stealth Writer and AI Paraphraser provided by Undetectable AI pose a challenge to the standard detectors.
Such specialized tools do not simply replace words, they rearrange sentences, change rhythm, change word complexity, and remove typical AI patterns that detectors monitor.
