Wordvice AI is the web-based, AI-powered writing and research tool platform at wordvice.ai. It offers an AI proofreader, paraphraser, translator, grammar checker, AI detector, PDF summarizer and other tools, with a free plan capped at 5,000 words per month. Everything below is taken from the platform’s own pages as read on 2026-11-07; plans and limits change, so treat the figures as “as listed on that date”.
What Wordvice AI is
Wordvice AI is a set of browser-based tools, plus Chrome and Microsoft Word extensions, aimed at people writing and reading academic text. The home page groups the tools into two sets.
- Writing tools: AI Proofreader, AI Paraphraser, AI Translator, AI Humanizer, Document Editor, Grammar Checker, AI Rewriter, Spell Checker, Punctuation Checker and Word Counter.
- Research tools: ChatPDF, AI Summarizer, PDF Summarizer, PDF Translator, Plagiarism Checker, AI Detector and a Citation Generator covering APA, MLA, Chicago and Vancouver.
Who runs it and what it covers
The site footer is marked “(c) 2026 Wordvice”. The paid human editing service, which is a separate product, lives on a different site (wordvice.com) and is linked from the platform. Do not confuse the two: the AI platform is software that returns suggestions immediately, while the human service assigns your file to an editor. See copyediting vs proofreading for what human editing levels mean.
Plans as listed on 2026-11-07
| Plan | Price shown | Allowance shown |
|---|---|---|
| Basic (free) | Free | 5,000 words per month; basic tools and basic revision modes |
| Premium | From $9.95 per month | 1,000,000 words per month; access to all Premium tools |
| Team | From $8.45 per month | One account, unlimited team members; discounts for 10 or more seats |
The home page states that advanced tool modes and features require the Premium plan. The interface is available in English, Korean, Japanese, Simplified and Traditional Chinese, German, French, Spanish and Italian. The grammar checker lists English, Chinese, Korean, Japanese, Spanish, French, German, Russian, Arabic, Portuguese and Italian.
How to use two of the tools
AI Detector
- Paste your text into the text box.
- Choose the language from the “Detect Language” dropdown.
- Click “Detect AI”.
The results appear in a report area and a “Sentence-Level AI Analysis” panel that labels sentences “Likely AI”, “Possibly AI” or “Unlikely AI”. The tool page says it uses perplexity and burstiness measures, names output from ChatGPT (GPT-3.5 and GPT-4), Google Gemini and Anthropic Claude as targets, and gives a probability score of likely origin. The page mentions a free character quota without stating the number, and its language count is stated two ways (30+ in the features text, over 47 in the FAQ). A detector score is a probability, not proof of authorship; see how another AI detection tool is described for wider context.
PDF Summarizer
- Drag and drop a PDF onto the upload area, or click it to upload (limit shown: 50 MB; PDF only).
- Summarize the whole file, select specific pages, or drag to highlight a passage.
The free allowance shown on the page is 100 pages uploaded and 100 pages summarized per month, with 300 MB of storage. Totals vary by subscription plan.
Data handling, tool by tool
Researchers often paste unpublished manuscripts into such tools, so what each tool page says about your text matters. The statements below are the tool pages’ own wording as read or seen on 2026-11-07; they are the vendor’s claims, not audited findings. Read Wordvice’s privacy policy and terms before submitting confidential or embargoed work.
| Tool page | What the page says about your content |
|---|---|
| AI Detector | Encrypted HTTPS transmission; temporary processing with automatic deletion; no third-party sharing; content never used for training. No retention period given. |
| AI Humanizer | Text is not stored after humanizing completes; not used to train models or shared. |
| PDF Summarizer and ChatPDF | Files are stored in your account until you delete them; chats are encrypted. |
| Grammar Checker and Word Counter | Refer to the Privacy Policy and Terms for collection and storage details; no training statement on the page. |
The practical consequence is that retention differs by tool: some pages state deletion after processing, while the PDF tools keep files in your account until you remove them.
Strengths and limits
- Documented strengths: a wide set of writing and research tools in one account; a free tier; extensions for Chrome and Word; multilingual interface and grammar checking.
- Limits stated on the pages: the free plan is 5,000 words per month and advanced modes need Premium; the PDF summarizer is PDF only with a 50 MB file cap; the AI detector gives probabilities, and its quota and language count are not stated consistently.
- Not established here: the accuracy of the proofreading, paraphrasing or detection outputs. This page makes no quality judgement; independent user reviews appear on listing sites such as Capterra and G2.
Using AI tools in a manuscript
Journals and publishers set their own rules on AI assistance, and a tool’s data promises do not change them. See ICMJE generative AI policy, generative AI disclosure statement and author responsibility for AI use. Check the target journal’s instructions before relying on any AI proofreader, paraphraser or translator, and see AI tools for improving academic writing style.
Alternatives
Wordvice AI sits in a crowded category. This table names the categories of alternatives and points to CASRAI pages that cover them; it states no vendor features, prices or limits, because those change and should be read from each vendor’s own pages.
| Category | Examples searchers compare | Where to read more |
|---|---|---|
| General AI paraphrasers and grammar checkers | Quillbot, Grammarly, Wordtune | Quillbot vs Grammarly; AI tools for improving academic writing style |
| Human editing and proofreading | Professional editing services, including Wordvice’s separate editing service | Copyediting vs proofreading |
| Reference managers with Word integration | Citation tools for in-document referencing | Reference managers that work inside Microsoft Word |
Whichever you choose, compare each vendor’s current plan page and data-handling statements, and check the target journal’s AI policy first.
