About
Scribbr is an AI-powered academic writing tool offering a plagiarism checker, grammar corrector, and citation generator, alongside professional proofreading services. It helps students and researchers ensure the originality, accuracy, and proper referencing of their work, significantly improving academic quality and integrity. Available on a freemium model, it empowers users to submit polished and well-cited assignments.
How to Use
- Go to scribbr.com and choose the tool you need: Plagiarism Checker, AI Detector, Grammar Checker, Citation Generator, or Paraphraser. Each tool is available separately from the main navigation.
- For the Plagiarism Checker: upload your Word or PDF document (up to 100,000 words) or paste text. Scribbr's checker is powered by iThenticate — the same engine used by many journals — and compares against 99 billion web pages and academic sources.
- For the AI Detector: paste up to 1,200 characters (free) or use the paid plan for full documents. Scribbr returns an AI percentage score and highlights the sentences most likely generated by an LLM.
- For the Citation Generator: search for a source by DOI, ISBN, URL, or title. Select your citation style (APA 7, MLA 9, Chicago, Harvard) and copy the formatted reference. You can build a full bibliography and export it to Word or BibTeX.
- For professional proofreading: upload your paper and select a turnaround time (24 h, 3 days, or 7 days). A human Scribbr editor corrects grammar, improves clarity, and checks citation formatting, returning a tracked-changes Word document.
- Review the plagiarism report's colour-coded similarity breakdown — separate percentages for internet sources, publications, and student papers help you distinguish legitimate citations from unattributed borrowing.

✓ Pros
- •iThenticate-powered plagiarism engine is the same technology used by Elsevier, Springer, and thousands of academic journals — giving students a research-grade check before submission.
- •Citation generator supports APA 7, MLA 9, Chicago, Harvard, and many discipline-specific styles, reducing one of the most time-consuming and error-prone parts of academic writing.
- •Bundled suite (plagiarism checker + AI detector + grammar checker + citation generator + paraphraser) means students can complete multiple writing quality checks in one place without juggling separate tools.
- •Optional human proofreading service connects the digital tool to a real editor, offering a level of feedback depth no automated grammar checker can match.
✗ Cons
- •AI Detector free tier is capped at 1,200 characters — far too short for a full essay, effectively requiring a paid plan for meaningful detection on student work.
- •Plagiarism checks are per-document purchases rather than a monthly subscription, making it expensive for students who need to check multiple drafts across several assignments.
- •Professional proofreading turnaround (minimum 24 h) is too slow for last-minute submission checks, limiting its utility when students need feedback under time pressure.
- •The platform is student-facing rather than instructor-facing — there is no class dashboard, batch upload, or LMS integration, so educators cannot use it as a systemic classroom tool.

Frequently Asked Questions
Is Scribbr's plagiarism checker the same as iThenticate?▾
Scribbr's plagiarism checker is built on the iThenticate engine (owned by Turnitin), which is the same technology used by major academic publishers and journals. This means the database coverage and matching algorithms are equivalent to a professional publication-review tool, not just a web-crawl search.
How current is Scribbr's AI detector compared to dedicated AI-detection tools?▾
Scribbr's AI detector is a useful addition to its writing suite but is not as specialised as dedicated tools like GPTZero or Originality.ai. The free tier's 1,200-character limit means it is best used for spot-checking specific passages rather than full documents. For systematic AI detection across a classroom, a dedicated educator tool with batch processing is more appropriate.
What citation styles does Scribbr's generator support?▾
Scribbr supports APA 7th edition, MLA 9th edition, Chicago (notes-bibliography and author-date), Harvard, and several discipline-specific formats including IEEE, Vancouver, and AMA. The generator accepts DOIs, ISBNs, URLs, and manual entry, and output can be exported as a formatted bibliography in Word or BibTeX for LaTeX documents.
Can Scribbr be used by educators as well as students?▾
Scribbr is primarily student-focused — it lacks class dashboards, bulk-upload, or LMS integration. Educators can use it to check their own materials or demonstrate citation formatting to students, but for institution-wide academic integrity workflows, a tool with LMS integration (Turnitin, Copyleaks) or a dedicated educator dashboard (GPTZero Educator) is a better fit.
