Duplichecker is different because of its user-friendly interface, no-cost, and versatile compared to other plagiarism checkers.

Duplichecker and Its Features

In addition to plagiarism scanning, Duplichecker provides a number of helpful writing utilities:

Plagiarism Checker

This is the core tool. It checks your text (1000 word for free) for copied content. After scanning, it shows the match percentage and highlights every duplicated phrase linking to the original sources. It supports uploading multiple formats (.docx, .pdf, .txt, etc.) and even lets you exclude specific URLs from the check. The plagiarism detector is AI-based and can spot well disguised matches (even paraphrased text) by analyzing sentence structure.

Grammar Checker

Duplichecker’s free grammar tool automatically finds spelling, punctuation and grammatical errors in any text. You simply paste your writing and select the language (it even auto detects). The checker underlines mistakes and suggests corrections similar to other grammar helpers. It works in many dialects of English (US, UK etc.) and is powered by AI/NLP for accuracy.

Paraphrasing Tool

The AI-powered paraphraser lets you rephrase sentences or paragraphs to avoid plagiarism or improve style. Just enter text (or upload a file) and the rephraser will return alternate versions in seconds. It offers different modes (Smart Spin, Ultra Spin, etc.) and supports multiple languages. This can help remove redundancy and generate 100% unique versions of your text.

Word Counter

A simple online counter that instantly computes word, character, sentence, and syllable counts. It also shows reading time. Just paste your content and click “Count Words.” This tool is 100% free and works on any device.

Additional Writing & SEO Tools

Beyond these, Duplichecker offers dozens of other free utilities. For example, it includes a reverse image search, keyword position checker, backlink checker, domain authority tool, and many text analysis tools. These extras make it a one-stop toolkit for writers and SEO users. All the tools are available from the same website, often without logging in.

Duplichecker: Free or Paid?

Duplichecker is generous with free features, but also offers paid plans for heavy users. Free usage: Anyone can use most tools (plagiarism, grammar, paraphrasing, etc.) at no charge. The free plagiarism checker lets you scan up to 1,000 words per search and run unlimited checks per day. There are no hidden fees and you don’t even need an account. However, the free service shows ads and has word limits per search.

Paid plans

To lift these limits, Duplichecker sells subscription plans. For example, their Premium plan unlocks higher word limits (tens of thousands of words) and removes ads. According to pricing info, the basic paid plan (around $10/month) covers roughly 30,000 words per month. Higher-tier plans allow more searches and team seats. For instance, a $25/month plan lets you check about 93,000 words monthly. These paid tiers include features like deep-search (larger search database) and API access for integration. In short, Duplichecker’s core tools are free to try, and upgrading (starting near $10/mo) gives you much larger quotas and pro features.

Alternatives to Duplichecker

Several other plagiarism checkers are popular for writers and educators. Each has its own focus and pricing:

Grammarly

Primarily a grammar/style tool, Grammarly’s Premium plan includes a plagiarism checker that scans content against billions of web pages and ProQuest academic databases. Unlike Duplichecker, Grammarly’s plagiarism check is not free – you must subscribe (starting around $12/month billed annually). Its strength is accuracy and integration (it also helps with style and citations).

Quetext

Quetext offers a free plagiarism checker (up to 500 words per search) and paid plans (from about $13.99/mo) for longer documents. It uses “DeepSearch™” technology to find plagiarism (and even detect AI-written text). Quetext also provides citation generation and AI-assisted paraphrasing tools. In essence, Quetext is like a more advanced, AI-driven alternative to Duplichecker, but with usage limits on the free tier.

Turnitin

Widely used in schools and universities, Turnitin is an enterprise-grade plagiarism service. It compares submissions against an enormous database of student papers and publications. Turnitin isn’t a consumer website – it’s licensed by institutions – so it has no free version. Its key advantage is the depth of its academic database and advanced reporting (it even detects AI-paraphrased text). However, for individual writers, Turnitin is not directly accessible.
