Overview

DupliChecker is a web-based content tool focused on originality checking (plagiarism detection) plus related utilities such as paraphrasing, grammar checking and some SEO/keyword tools. You upload or paste text (or file) and it scans for duplication and other issues.

If you’re creating content—student essays, blog articles, marketing copy, or academic papers—you want to avoid plagiarism, improve readability and ensure your content is unique. DupliChecker gives a fast and accessible way to do this online without installing software. For small teams or solo creators, it offers a lower-cost entry compared with high-end tools.

You paste text (or upload a file like .doc/.pdf/.txt/.rtf/.odt). The tool runs a scan against web sources and shows you the percentage of your content that appears duplicated, highlights matching fragments and tags potential sources. It also offers a paraphrasing tool (to rewrite content) and grammar check. Free tier allows limited word count per search; paid tiers increase limits. Some file upload formats are supported.

FAQ

Can I use DupliChecker commercially (for my blog or content agency)? ▼

Yes—your content checking is your use. The tool doesn’t claim you cannot use it commercially. You retain your content. But if you publish work, you still must ensure you comply with copyright/usage laws of underlying content you reference.

How many words or pages can I check per month? ▼

The free tier allows up to ~1,000 words per search (and likely limited searches). Paid tiers raise both search counts and total word counts (e.g., a $5/week plan offers ~10,000 words)

Can I upload documents like .pdf or .docx? ▼

Yes — DupliChecker supports multiple upload formats (.tex, .txt, .doc, .docx, .odt, .pdf, .rtf) for the plagiarism checker.

Does DupliChecker integrate via API or support team seats? ▼

Some paid plans list “API” or “User Seats” but the lower tiers show “API unavailable” and “User Seats = 0”. For team-use or API integration you’ll need a higher-tier plan and check the specific plan details.

Does the service store my uploaded text or train on it? ▼

The site claims uploaded material isn’t saved and is deleted after checking. However, there is no detailed public documentation about training or reuse of uploaded content. Use caution if you have sensitive or confidential text.

What differentiates the paid plan vs. free plan? ▼

Paid plans increase the word-limit and search quotas, remove ads, may support more file sizes, larger documents per search (up to ~25,000 words per search) and possibly include additional features like downloadable PDF reports.
